Assessing Procedural Justice During Police-Citizen Encounters with Officer Surveys, Citizen Surveys, and Systematic Social Observations, Norfolk, VA, 2017-2019 (ICPSR 37455)
Released/updated on: 2023-01-31
Geographic coverage: United States, Virginia, Norfolk
Time period: 2017-01-01--2019-01-01
This study aimed to improve the understanding of procedural justice during police-citizen encounters with a comprehensive approach including officer surveys, systematic social observations, and citizen surveys.
First, the study used officer surveys to evaluate the effectiveness of a procedural justice training program in Norfolk, Virginia. In 2017, an eight-hour training was conducted for all Norfolk police officers. A pretest and posttest survey was given to each officer during the training, which asked about their opinions on a multitude of statements representing the key elements of procedural justice in policing (e.g., voice, respect, trustworthiness, and neutrality). In 2019, the officers were given a second-wave survey to assess the long-term effects of the training.
The study also examined officers' procedurally fair behavior during interactions and citizens' behavioral responses through systematic social observations of police-citizen interactions captured by the police body-worn cameras. Patrol shifts were randomly selected and observed between December 2017 and March 2019.
The third component included a survey of citizens who interacted with the police during the observation period. Randomly selected officers were, prior to the shift, encouraged to hand out survey cards to all citizens they encountered. These cards invited the citizens to take a survey online. Citizens could also give their phone numbers to the officers so that they could be contacted to take the survey over the phone. The goal of the citizen survey was to obtain information about the citizens' opinions of the Norfolk police in general and the specific encounters they had with the Norfolk police.
Taken together, the three components of this study offered a systematic understanding of the policing issues related to procedural justice, including officers' perceptions about procedural justice, officers' procedurally fair behavior during interactions, citizens' behavioral responses, and citizens' subjective evaluations of their encounters.

Decision-Related Research on the Organization of Service Delivery Systems in Metropolitan Areas: Police Protection (ICPSR 7427)
Released/updated on: 2006-03-30
Geographic coverage: United States
Time period: 1970-01-01--1975-01-01
This study represents one of four research projects on service delivery systems in metropolitan areas, covering fire protection (DECISION-RELATED RESEARCH ON THE ORGANIZATION OF SERVICE DELIVERY SYSTEMS IN METROPOLITAN AREAS: FIRE PROTECTION [ICPSR 7409]), public health (DECISION-RELATED RESEARCH ON THE ORGANIZATION OF SERVICE DELIVERY SYSTEMS IN METROPOLITAN AREAS: PUBLIC HEALTH [ICPSR 7374]), solid waste management (DECISION-RELATED RESEARCH ON THE ORGANIZATION OF SERVICE DELIVERY SYSTEMS IN METROPOLITAN AREAS: SOLID WASTE MANAGEMENT [ICPSR 7487]), and police protection (the present study). All four projects used a common unit of analysis, namely all 200 Standard Metropolitan Statistical Areas (SMSAs) that, according to the 1970 Census, had a population of less than 1,500,000 and were entirely located within a single state. In each project, a limited amount of information was collected for all 200 SMSAs. More extensive data were gathered within independently drawn samples of these SMSAs, for all local geographical units and each administrative jurisdiction or agency in the service delivery areas. Two standardized systems of geocoding -- the Federal Information Processing Standard (FIPS) codes and the Office of Revenue Sharing (ORS) codes -- were used, so that data from various sources could be combined. The use of these two coding schemes also allows users to combine data from two or more of the research projects conducted in conjunction with the present one, or to add data from a wide variety of public data files. The present study used five major clusters of variables to investigate the delivery of police services: service conditions, the legal structure, organizational arrangements, manpower levels, and expenditure levels. Information about specific services such as patrol, traffic control, criminal investigation, radio communications, adult pre-trial detention, entry-level training, and crime laboratory analysis was collected at the local jurisdiction level in a random sample of 80 SMSAs. Part 1 summarizes in matrix form the relationships between all consumers and producers for each type of service in a given SMSA. Part 2 provides data about 1,885 consuming units, or service areas, defined as mutually exclusive geographical divisions of each SMSA that received police services. Part 3 contains information for 1,761 police agencies, defined as service producers, with functions and duties that may overlap several jurisdictions.

Developing a Common Metric for Evaluating Police Performance in Deadly Force Situations in the United States, 2009-2011 (ICPSR 33141)
Released/updated on: 2014-06-18
Geographic coverage: United States
Time period: 2009-07-01--2011-09-01
This study developed interval-level measurement scales for evaluating police officer performance during real or simulated deadly force situations. Through a two-day concept mapping focus group, statements were identified to describe two sets of dynamics: the difficulty (D) of a deadly force situation and the performance (P) of a police officer in that situation. These statements were then operationalized into measurable Likert-scale items that were scored by 291 use of force instructors from more than 100 agencies across the United States using an online survey instrument. The dataset resulting from this process contains a total of 685 variables, comprised of 312 difficulty statement items, 278 performance statement items, and 94 variables that measure the demographic characteristics of the scorers.

Enhancing Procedural Justness of Encounters Through Substantiation (EPJETS): The Atlantic County Randomized Controlled Trial, New Jersey, 2022-2024 (ICPSR 39659)
Released/updated on: 2026-03-11
Geographic coverage: Atlantic City, United States, Pleasantville, New Jersey
Time period: 2022-01-01--2024-01-01
The Enhancing Procedural Justness of Encounters Through Substantiation (EPJETS) project was a collaborative initiative between researchers from Stockton, Rutgers, and Northwestern Universities and the police departments of Atlantic City and Pleasantville, New Jersey that aimed to test whether incorporating principles of procedural justice, sharing body-worn camera (BWC) footage with drivers following traffic stops, and strategically targeting identified high-traffic crash locations for enforcement could improve public trust and perceptions of police legitimacy. Between October 2022 and June 2024, the study evaluated 1,423 traffic stops conducted for speeding violations by comparing standard enforcement protocols to a novel procedural justice-based intervention. Drivers who were speeding were surveyed immediately after the stop by researchers to determine whether the EPJETS protocol positively affected their perceptions of officer treatment and the effectiveness of BWCs.

Enhancing the Research Partnership Between the Albany Police Department and the Finn Institute, 2005-2016 (ICPSR 37820)
Released/updated on: 2020-12-16
Geographic coverage: United States, New York (state), Albany (New York)
Time period: 2005-01-01--2016-01-01
The Finn Institute is an independent, not-for-profit corporation that conducts research on matters of public safety and security. The project provided for steps that would strengthen and enhance an existing police-researcher partnership, focused around analyses of proactive policing. As part of a research partnership with the Albany Police Department (APD) and the Finn Institute, this study was oriented around a basic research question: can proactive policing be conducted more efficiently, in the sense that a better ratio of high-value to lower-value stops is achieved, such that the trade-off between crime reduction and police community relations is mitigated.
Albany Resident Survey Dataset (DS1) unit of analysis was individuals. Variables include neighborhood crime and disorder, legitimacy and satisfaction with police service, and direct and vicarious experience with stop and perceptions of stops as a problem. Demographic variables include age, race, education, employment, marital status, and household count.
Management of "Smart Stops" Dataset (DS2) unit of analysis was investigatory stops; variables include records of individual stops, the month and year of the stop, whether the location of the stop was a high-crime location, whether the person stopped (or any of the persons stopped, if multiple people were stopped at one time) were high-risk, and whether the stop resulted in an arrest.
Trends in Proactive Policing Dataset (DS3) unit of analysis was APD officers. Variables include number of stops per quarter; variables include demographics such as officer characteristics such as their assignments, length of service, and gender.

Evaluation of Grants to Encourage Arrest Policies for Domestic Violence Cases in the State College, Pennsylvania, Police Department, 1999-2000 (ICPSR 3166)
Released/updated on: 2006-03-30
Geographic coverage: United States, Pennsylvania
This project was an 18-month long research-practitioner partnership to conduct a process evaluation of the State College Police Department's implementation of a grant to encourage arrest policies for domestic violence. The general goals of the process evaluation were to assess how and to what extent the State College Police Department's proposed activities were implemented as planned, based on the rationale that such activities would enhance the potential for increasing victim safety and perpetrator accountability systemically. As part of the grant, the police department sought to improve case tracking and services to victims by developing new specialized positions for domestic violence, including: (1) a domestic violence arrest coordinator from within the State College Police Department who was responsible for monitoring case outcomes through the courts and updating domestic violence policies and training (Part 1, Victim Tracking Data from Domestic Violence Coordinator), (2) a victims service attorney from Legal Services who was responsible for handling civil law issues for domestic violence victims, including support, child custody, employment, financial, consumer, public benefits, and housing issues (Part 2, Victim Tracking Data From Victim Services Attorney), and (3) an intensive domestic violence probation officer from the Centre County Probation and Parole Department who was responsible for providing close supervision and follow-up of batterers (Part 3, Offender Tracking Data). Researchers worked with practitioners to develop databases suitable for monitoring service provision by the three newly-created positions for domestic violence cases. Major categories of data collected on the victim tracking form (Parts 1 and 2) included location of initial contact, type of initial contact, referral source, reason for initial contact, service/consultation provided at initial contact, meetings, and referrals out. Types of services provided include reporting abuse, filing a Protection from Abuse order, legal representation, and assistance with court procedures. Major categories of data collected on the offender tracking form (Part 3) included location of initial contact, type of initial contact, referral source, reason for initial contact, service/consultation provided, charges, sentence received, relationship between the victim and perpetrator, marital status, children in the home, referrals out, presentencing investigation completed, prior criminal history, and reason for termination. Types of services provided include pre-sentence investigation, placement on supervision, and assessment and evaluation. In addition to developing these new positions, the police department also sought to improve how officers handled domestic violence cases through a two-day training program. The evaluation conducted pre- and post-training assessments of all personnel training in 1999 and conducted follow-up surveys to assess the long-term impact of training. For Part 4, Police Training Survey Data, surveys were administered to law enforcement personnel participating in a two-day domestic violence training program. Surveys were administered both before and after the training program and focused on knowledge about domestic violence policies and protocols, attitudes and beliefs about domestic violence, and the background and experience of the officers. Within six months after the training, the same participants were contacted to complete a follow-up survey. Variables in Part 4 measure how well officers knew domestic violence arrest policies, their attitudes toward abused women and how to handle domestic violence cases, and their opinions about training. Demographic variables in Part 4 include age, sex, race, education, and years in law enforcement.

Evaluation of Law Enforcement Training for Domestic Violence Cases in a Southwestern City in Texas, 1997-1999 (ICPSR 3400)
Released/updated on: 2006-03-30
Geographic coverage: United States, Texas
Time period: 1997-01-01--1999-01-01
This study was an outcome evaluation of the effects of the Duluth Domestic Abuse Intervention Project Training Model for Law Enforcement Response on police officer attitudes toward domestic violence. Data on the effectiveness of the training were collected by means of an attitude survey of law enforcement officers (Part 1). Additionally, two experimental designs (Part 2) were implemented to test the effects of the Duluth model training on (1) time spent by police officers at the scene of a domestic violence incident, and (2) the number of convictions. Variables for Part 1 include the assigned research group and respondents' level of agreement with various statements, such as: alcohol is the primary cause of family violence, men are more likely than women to be aggressive, only mentally ill people batter their families, mandatory arrest of offenders is the best way to reduce repeat episodes of violence, family violence is a private matter, law enforcement policies are ineffective for preventing family violence, children of single-parent, female-headed families are abused more than children of dual-parent households, and prosecution of an offender is unlikely regardless of how well a victim cooperates. Index scores calculated from groupings of various variables are included as well as whether the respondent found training interesting, relevant, well-organized, and useful. Demographic variables for each respondent include race, gender, age, and assignment and position in the police department. Variables for Part 2 include whether the domestic violence case occurred before or after training, to which test group the case belongs, the amount of time in minutes spent on the domestic violence scene, and whether the case resulted in a conviction.

Evaluation of the Elder Abuse Training Program in Massachusetts, 1993-1995 (ICPSR 6921)
Released/updated on: 1998-01-12
Geographic coverage: United States, Massachusetts
Time period: 1993-09-01--1995-02-01
These data were collected to evaluate the Elder Protection Project in Massachusetts, sponsored by the Massachusetts Attorney General's Office and funded by the Massachusetts Committee on Criminal Justice. The mission of the project was to train police officers to be aware of the changing demographics of the elderly population in Massachusetts and to communicate effectively and sensitively with senior adults so that officers could effectively intervene, report, and investigate instances of elder victimization, neglect, and financial exploitation. These data examine the quality of instruction given at the advanced training sessions conducted between September 1993 and May 1994 and offered in all regions of the state in coordination with local protective service agencies. Variables include the respondent's agency and job title, type of elder abuse programs offered by the agency, the respondent's estimate of the percentage of actual elder abuse reported in his/her area, and the respondent's opinion on the greatest obstacles to having elder abuse reported. Respondents rated their knowledge of elder abuse reporting laws, procedures for responding to elder abuse incidents, unique aspects of communicating with elderly people, and formal training on recognizing signs of elder abuse. Respondents that completed the two-day advanced law enforcement elder abuse training program rated the quality of the training and were also asked about issues related to elder abuse not covered in the training, names of new programs in the department or agency initiated as a result of the training, aspects of the training most useful and least useful, and suggestions regarding how the training program could be improved.

Evaluation of the Gang Resistance Education and Training (GREAT) Program in the United States, 1995-1999 (ICPSR 3337)
Released/updated on: 2015-08-21
Geographic coverage: United States
Time period: 1995-01-01--1999-01-01
This study sought to evaluate the effectiveness of the Gang Resistance Education And Training (GREAT) program by surveying five different groups: students in a cross-sectional design (Part 1), law enforcement officers (Part 2), educators (Part 3), parents (Part 4), and students in a longitudinal design (Part 5). Middle school students in the cross-sectional design were surveyed to examine GREAT's short- and long-term effects, and to assess the quality and effectiveness of officer training. Law enforcement officers were surveyed to determine whether their perceptions and expectations of the GREAT program varied depending on sex, race, rank, age, level of education, and length of time working in policing. Data were collected from middle school personnel (administrators, counselors, and teachers) in order to assess educators' attitudes toward and perceptions of the effectiveness of the GREAT program, including the curriculum's appropriateness for middle school students and its effectiveness in delinquency and gang prevention both in the school and in the community. Parents were surveyed to assess their attitudes toward crime and gangs in their community, school prevention programs, the role of police in the school, and their satisfaction with and perceptions of the effectiveness of the GREAT program. The middle school students participating in the longitudinal aspect of this study were surveyed to examine the change in attitudes and behavior, germane to gang activity, over time. Variables for all parts were geared toward assessing perception and attitudes about the police and the GREAT program and their overall effectiveness, community involvement, neighborhood crime, and gang-related activities.

Geographic coverage: New York City, United States, New York (state)
Time period: 1986-01-01--1989-01-01
The purpose of this study was to examine whether the Police Cadet Corps program in New York City had achieved its goal of improving the police force through additional training of applicants with higher education. The evaluation of the program was designed to answer questions such as (1) How was the program recruitment implemented, and with what success? (2) What were the role-related perceptions and attitudes of the cadets and how did they differ, if at all, among different types of cadets and from those of the members of the latest recruit class? (3) How, if at all, did the program experience affect the cadets' perceptions and attitudes? and (4) How did the attitudes and perceptions of cadets compare to non-cadet recruits with and without some college education in the same academy class? Four cohorts of cadets were asked to complete several different questionnaires throughout the course of the program, which culminated in graduation from the police academy. Two sets of non-cadet recruits from the academy were also included in the research. Major variables in the data collection detail reasons for entry into the police department, opinions regarding police, and perceptions and attitudes toward the police cadet program. Some questionnaires also provided information on demographic characteristics of the cadets (race, sex, marital status, military service and branch, highest level of education, family income, and year of birth). The unit of observation is the New York City police cadet.

Geographic coverage: San Francisco, United States, California
Time period: 1999-01-01--2000-01-01
In an effort to reduce the workload of police officers participating in problem-solving and community-oriented activities, the San Francisco Police Department applied for and was awarded a Community Oriented Policing Services (COPS) Making Officer Redeployment Effective (MORE) grant in 1995 to integrate Mobile Computing Terminals (MCTs), or laptop computers, into its daily operations. The National Institute of Justice funded an evaluation of this COPS MORE initiative. The evaluation examined the efficacy of a technological intervention to improve operational efficiency, service quality, and the corresponding changes in officers' attitudes and behaviors associated with integrating the use of MCTs for computerized incident reporting into the work process. The two systematic methods of data collection used for this research project were pencil-and-paper surveys of officers' attitudes toward computers and community policing and direct observation of the behavior of officers on patrol, including measurements of time to complete reports and time engaged in police activities.

Evaluation of Victim Advocacy Services Funded by the Violence Against Women Act in Urban Ohio, 1999 (ICPSR 2992)
Released/updated on: 2006-03-30
Geographic coverage: United States, Ohio
The focus of this research and evaluation endeavor was on direct service programs in Ohio, particularly advocacy services for female victims of violence, receiving funding through the Services, Training, Officers, Prosecutors (STOP) formula grants under the Violence Against Women Act (VAWA) of 1994. The objectives of this project were (1) to describe and compare existing advocacy services in Ohio, (2) to compare victim advocacy typologies and identify key variables in the delivery of services, (3) to develop a better understanding of how victim advocacy services are defined and delivered, and (4) to assess the effectiveness of those services. For Part 1, Service Agencies Data, comprehensive information about 13 VAWA-funded programs providing direct services in urban Ohio was gathered through a mailback questionnaire and phone interviews. Detailed information was collected on organizational structure, clients served, and agency services. Focus groups were also used to collect data from clients (Parts 3-11) and staff (Parts 12-23) about their definitions of advocacy, types of services needed by victims, services provided to victims, and important outcomes for service providers. Part 2, Police Officer Data, focused on police officers' attitudes toward domestic violence and on evaluating service outcomes in one particular agency. The agency selected was a prosecutor's office that planned to improve services to victims by changing how the police and prosecutors responded to domestic violence cases. The prosecutor's office selected one police district as the site for implementing the new program, which included training police officers and placing a prosecutor in the district office to work directly with the police on domestic violence cases. The evaluation of this program was designed to assess the effectiveness of the police officers' training and officers' increased access to information from the prosecutor on the outcome of the case. Police officers from the selected district were administered surveys. Also surveyed were officers from another district that handled a similar number of domestic violence cases and had a comparable number of officers employed in the district. Variables in Part 1 include number of staff, budget, funding sources, number and type of victims served, target population, number of victims served speaking languages other than English, number of juveniles and adults served, number of victims with special needs served, collaboration with other organizations, benefits of VAWA funding, and direct and referral services provided by the agency. Variables in Part 2 cover police officers' views on whether it was a waste of time to prosecute domestic violence cases, if these cases were likely to result in a conviction, whether they felt sympathetic toward the victim or blamed the victim, how the prosecution should proceed with domestic violence cases, how the prosecution and police worked together on such cases, whether domestic violence was a private matter, and how they felt about the new program implemented under VAWA.

The California correctional system underwent a dramatic transformation under California's Public Safety Realignment Act (AB 109) in 2011, a law that shifted from the state to the counties the responsibility for monitoring, tracking, and incarcerating lower level offenders previously bound for state prison. Realignment, therefore, presents the opportunity to witness 58 natural experiments in the downsizing of prisons. Counties faced different types of offenders, implemented different programs in different community and jail environments, and adopted differing sanctioning policies. This study examines the California's Public Safety Realignment Act's effect on counties' criminal justice institutions, including the disparities that result in charging, sentencing, and resource decisions.

Impact of Community Policing at the Street Level: An Observational Study in Richmond, Virginia, 1992 (ICPSR 2612)
Released/updated on: 2006-03-30
This study's purpose was twofold: to investigate the nature of police patrol work in a community policing context and to field-test data collection instruments designed for systematic social observation. The project, conducted in Richmond, Virginia, where its police department was in the third year of a five-year plan to implement community policing, was designed as a case study of one police department's experience with community policing, focusing on officers in the patrol division. A team of eight researchers conducted observations with the police officers in the spring and summer of 1992. A total of 120 officers were observed during 125 observation sessions. Observers accompanied officers throughout their regular work shifts, taking brief field notes on officers' activities and encounters with the public. All of an observed officer's time during the shift was accounted for by either encounters or activities. Within 15 hours of the completion of the ridealong, the observer prepared a detailed narrative account of events that occurred during the ridealong and coded key items associated with these events. The study generated five nested quantitative datasets that can be linked by common variables. Part 1, Ridealong Data, provides information pertinent to the 125 observation sessions or "rides." Part 2, Activity Data, focuses on 5,576 activities conducted by officers when not engaged in encounters. Data in Part 3, Encounter Data, describe 1,098 encounters with citizens during the ridealongs. An encounter was defined as a communication between officers and citizens that took over one minute, involved more than three verbal exchanges between an officer and a citizen, or involved significant physical contact between the officer and citizen. Part 4, Citizen Data, provides data relevant to each of the 1,630 citizens engaged by police in the encounters. Some encounters involved more than one citizen. Part 5, Arrest Data, was constructed by merging Parts 1, 3, and 4, and provides information on 451 encounters that occurred during the ridealongs in which the citizen was suspected of some criminal mischief. All identification variables in this collection were created by the researchers for this project. Variables from Part 1 include date, start time, end time, unit, and beat assignment of the observation session, and the primary officer's and secondary officer's sex, race/ethnicity, years as an officer, months assigned to precinct and beat, hours of community policing training, and general orientation to community policing. Variables in Part 2 specify the time the activity began and ended, who initiated the activity, type, location, and visibility of the activity, involvement of the officer's supervisor during the activity, and if the activity involved problem-solving, or meeting with citizens or other community organizations. Part 3 variables include time encounter began and ended, who initiated the encounter, primary and secondary officer's energy level and mood before the encounter, problem as radioed by dispatcher, and problem as it appeared at the beginning of the encounter and at the end of the encounter. Information on the location of the encounter includes percent of time at initial location, visibility, officer's prior knowledge of the initial location, and if the officer anticipated violence at the scene. Additional variables focus on the presence of a supervisor, other police officers, service personnel, bystanders, and participants, if the officer filed or intended to file a report, if the officer engaged in problem-solving, and factors that influenced the officer's actions. Citizen information in Part 4 includes sex, age, and race/ethnicity of the citizen, role in the encounter, if the citizen appeared to be of low income, under the use of alcohol or drugs, or appeared to have a mental disorder or physical injury or illness, if the citizen was representing an establishment, if the citizen lived, worked, or owned property in the police beat, and if the citizen had a weapon. Also presented are various aspects of the police-citizen interaction, such as evidence considered by the officer, requests and responses to each other, and changes in actions during the encounter. Variables in Part 5 record the officer's orientation toward community policing, if the suspect was arrested or cited, if the offense was serious or drug-related, amount of evidence, if the victim requested that the suspect be arrested, if the victim was white, Black, and of low income, and if the suspect represented an organization. Information on the suspect includes gender, race, sobriety level, if of low income, if 19 years old or less, if actively resistant, if the officer knew the suspect adversarially, and if the suspect demonstrated conflict with others. Some items were recoded for the particular analyses for which the Arrest Data were constructed.

Impact of Community Policing Training and Program Implementation on Police Personnel in Arizona, 1995-1998 (ICPSR 3789)
Released/updated on: 2005-11-04
Geographic coverage: United States, Arizona
Time period: 1995-12-01--1998-02-01
This study examined the impact on police trainees of the Phoenix Regional Training Academy's curriculum. The academy's basic training program integrates community policing and problem-oriented policing across the curriculum. A multiple-treatment single-case design was used to study 446 police recruits from 14 successive academy classes that began basic training classes between December 1995 and October 1996. The Police Personnel Survey, adapted from Rosenbaum, Yeh, and Wilkinson (1994), Skogan (1994, 1995), and Wycoff and Skogan (1993), was administered to officers in the study on four separate occasions. This instrument was designed to take repeated measures of police officer attitudes and beliefs related to various dimensions of the job, including job satisfaction, community policing, problem-solving policing, traditional policing, the role of the police, relations with the community, and multicultural sensitivity.

Impact of Oleoresin Capsicum Spray on Respiratory Function in Human Subjects in the Sitting and Prone Maximal Restraint Positions in San Diego County, 1998 (ICPSR 2961)
Released/updated on: 2006-03-30
Geographic coverage: San Diego, United States, California
Oleoresin capsicum (OC), or pepper spray, has gained wide acceptance as standard police equipment in law enforcement as a swift and effective method to subdue violent, dangerous suspects in the field. As a use-of-force method, however, OC spray has been alleged in the media to have been associated with a number of in-custody deaths. The goal of this study was to assess the safety of a commercially available OC spray in use by law enforcement agencies nationwide. The study was conducted as a randomized, cross-over, controlled trial on volunteer human subjects recruited from the local law enforcement training academy in San Diego County, California. Subjects participated in four different experimental trials in random order over two separate days in a pulmonary function testing laboratory: (a) placebo spray exposure followed by sitting position, (b) placebo spray exposure followed by restraint position, (c) OC spray exposure followed by sitting position, and (d) OC spray exposure followed by restraint position. Prior to participation, subjects completed a short questionnaire regarding their health status, history of lung disease and asthma, smoking history, medication use, and respiratory inhaler medication use. Prior to exposure, subjects also underwent a brief screening spirometry in the sitting position by means of a portable spirometry device to determine baseline pulmonary function. Subjects then placed their heads in a 5' x 3' x 3' exposure box that allowed their faces to be exposed to the spray. A one-second spray was delivered into the box from the end opposite the subject (approximately five feet away). Subjects remained in the box for five seconds after the spray was delivered. During this time, subjects underwent impedance monitoring to assess whether inhalation of the OC or placebo spray had occurred. After this exposure period, subjects were placed in either the sitting or prone maximal restraint position. Subjects remained in these positions for ten minutes. Repeat spirometric measurements were performed, oxygen saturation, blood pressure, end-tidal carbon dioxide levels, and pulse rate were recorded, and an arterial blood sample was drawn. A total of 34 subjects completed the study, comprising 128 separate analyzable study trials. Variables provided in all three parts of this collection include subject's age, gender, ethnicity, height, weight, body mass index, past medical history, tobacco use history, and history of medication use, as well as OC spray or placebo exposure and sitting or restraint position during the trial. Part 1 also includes tidal volume, respiratory rate, and heart rate at baseline and at 1, 5, 7, and 9 minutes, and systolic and diastolic blood pressure at baseline and at 3, 6, and 9 minutes. Additional variables in Part 2 include predicted forced vital capacity and predicted forced expiratory volume in 1 second, and the same measures at baseline, 1.5 minutes, and 10 minutes. Derived variables include percent predicted and mean percent predicted values involving the above variables. Part 3 also provides end-tidal carbon dioxide and oxygenation levels, oxygen saturation, oxygen consumption at baseline and at 1, 5, 7, and 9 minutes, blood pH, partial pressure of oxygen, and partial pressure of carbon dioxide at 8 minutes.

Law Enforcement Family Support: Demonstration Project (L.E.A.F.S.) 1998-1999 (ICPSR 29422)
Released/updated on: 2012-06-04
Geographic coverage: United States, Tennessee
Time period: 1998-01-01--1999-01-01
The Law Enforcement and Family Support program consists of multi-dimensional stress management services for law enforcement personnel within the state of Tennessee. The Tennessee Sheriffs' Association was awarded a grant to develop, demonstrate, and test innovative stress-reduction and support programs for State or local law enforcement personnel and their families. Over an 18-month period, a framework of stress-related services on a statewide basis for law enforcement personnel and their families was developed. The services cover a range of activities from on-scene defusings to group therapy for families, children, and couples. Its focus is the early recognition and provision of services, which preserves confidentiality while utilizing extensive peer support. The program implemented a model for a stress reduction program at regional law enforcement training academies and produced a text/workbook for educating new recruits and their families on stress related topics. In addition, this program incorporated a monitoring and evaluation component, which consisted of three studies, a Baseline Study, a Critical Incident Stress Debriefing (C.I.S.D.) Study, and an Evaluation of C.I.S.D. Peer and Family Teams Study, all of which utilized a design that attempted to test the efficacy of services provided to law enforcement personnel and their families and are described in more detail below.
Baseline Study (Dataset 1) - A baseline survey, the Tennessee Law Enforcement Officer Questionnaire, was developed and distributed to officers in a randomly selected number of departments from each of three regions: West, Middle, and East. The agencies from each region were matched based on demographics such as number of sworn officers. In addition to demographic information, participants were asked to identify their awareness of 19 services that may be offered by their agency as well as the utilization and willingness to use these services. The final section of the questionnaire asked participants to identify post-traumatic stress disorder symptoms that they may have experienced after a critical incident on the job. All law enforcement agencies in Tennessee were organized into groups based on type of agency (City, County, State). Agencies from each group were randomly selected. A summary of the data from Time 1 provides Tennessee with a baseline of the current awareness, utilization, and willingness to use services. In addition, this data provides an understanding of the number of critical incidents that law enforcement officers in Tennessee have experienced as well as the potential to which these incidences have impacted officers' perception of their performance.
Critical Incident Stress Debriefing (C.I.S.D.) Study (Datasets 2 and 3) - The goal of this portion of the project was to determine the effectiveness of critical incidents stress debriefing (CISD) as a means to assist officers in dealing with the negative effects of exposure to a critical incident. To identify the effectiveness of the CISD intervention as well as the support programs in each region, information was collected from officers who participated in a debriefing at three time periods (i.e. prior to CISD, 2-weeks after CISD, 3-months after CISD). The Western region received only Critical Incident Stress Debriefing (CISD), the Eastern region received CISD, and Peer Support, and the Middle region received CISD, Peer Support, and Family Support. Participants were asked to identify what services they and their family may have used (e.g. EAP, Counseling, Family Support Team, Peer Support Team, Training Seminar). Additionally, participants were asked to identify any health problems they experienced since the incident, and lost work time as a result of the incident. A CISD Team member identified the type of critical incident that the officer experienced.
Evaluation of the C.I.S.D. Peer and Family Teams Study (Dataset 4) - The goal of this section of the evaluation process was to identify the impact that the three Teams had on participants. Specifically participants' perception of the usefulness of the Teams and what was gained from their interaction with the Teams was to be measured. Initially, the Team evaluation forms were to be filled out by every individual who participated in a debriefing at the 2-week and 3-month periods. Asking participants to complete Team evaluations at these time periods would allow participants in the Middle region to have exposure to the Family Support and Peer Support Teams, and participants in the Eastern region to have exposure to a Peer Support Team. The procedure was modified so that Team evaluations were conducted at the completion of the project. The evaluation first asked the participant to identify if they had been contacted by a member of a Team (CISD, Peer, Family).
The Part 1 (Baseline) data public and restricted files contain 5,425 cases and 157 variables. The Part 2 (Critical Incident Stress Debriefing) data public and restricted files contain 329 cases and 189 variables. The Part 3 (Critical Incident Stress Debriefing Matched Cases) data public and restricted files contain 236 cases and 354 variables. The Part 4 (Evaluation of CISD Peer and Family Teams) data public and restricted files contain 81 cases and 24 variables.

Line Police Officer Knowledge of Search and Seizure Law: An Exploratory Multi-city Test in the United States, 1986-1987 (ICPSR 9981)
Released/updated on: 2006-01-12
Geographic coverage: United States
Time period: 1986-01-01--1987-01-01
This data collection was undertaken to gather information on the extent of police officers' knowledge of search and seizure law, an issue with important consequences for law enforcement. A specially-produced videotape depicting line duty situations that uniformed police officers frequently encounter was viewed by 478 line uniformed police officers from 52 randomly-selected cities in which search and seizure laws were determined to be no more restrictive than applicable United States Supreme Court decisions. Testing of the police officers occurred in all regions as established by the Federal Bureau of Investigation, except for the Pacific region (California, Oregon, and Washington), since search and seizure laws in these states are, in some instances, more restrictive than United States Supreme Court decisions. No testing occurred in cities with populations under 10,000 because of budget limitations. Fourteen questions to which the officers responded were presented in the videotape. Each police officer also completed a questionnaire that included questions on demographics, training, and work experience, covering their age, sex, race, shift worked, years of police experience, education, training on search and seizure law, effectiveness of various types of training instructors and methods, how easily they could obtain advice about search and seizure questions they encountered, and court outcomes of search and seizure cases in which they were involved. Police department representatives completed a separate questionnaire providing department characteristics and information on search and seizure training and procedures, such as the number of sworn officers, existence of general training and the number of hours required, existence of in-service search and seizure training and the number of hours and testing required, existence of policies and procedures on search and seizure, and means of advice available to officers about search and seizure questions. These data comprise Part 1. For purposes of comparison and interpretation of the police officer test scores, question responses were also obtained from other sources. Part 2 contains responses from 36 judges from states with search and seizure laws no more restrictive than the United States Supreme Court decisions, as well as responses from a demographic and work-experience questionnaire inquiring about their age, law school attendance, general judicial experience, and judicial experience and education specific to search and seizure laws. All geographic regions except New England and the Pacific were represented by the judges. Part 3, Comparison Data, contains answers to the 14 test questions only, from 15 elected district attorneys, 6 assistant district attorneys, the district attorney in another city and 11 of his assistant district attorneys, a police attorney with expertise in search and seizure law, 24 police academy trainees with no previous police work experience who were tested before search and seizure law training, a second group of 17 police academy trainees -- some with police work experience but no search and seizure law training, 55 law enforcement officer trainees from a third academy tested immediately after search and seizure training, 7 technical college students with no previous education or training on search and seizure law, and 27 university criminal justice course students, also with no search and seizure law education or training.

Geographic coverage: United States, Texas, Massachusetts, Los Angeles, California, Florida, Las Vegas, Boston, Nevada, Miami, Houston
Time period: 2007-01-01--2010-01-01
This study examines the state of counterterrorism and homeland security in five large urban law enforcement agencies (the Boston Police Department, the Houston Police Department, the Las Vegas Metropolitan Police Department, the Los Angeles County Sheriff's Department, and the Miami-Dade Police Department) nine years following the September 11, 2001, terrorist attacks. It explores the long-term adjustments that these agencies made to accommodate this new role.
Researchers from the RAND Corporation, in consultation with National Institute of Justice project staff, selected law enforcement agencies of major urban areas with a high risk of terrorist attacks from different regions of the United States that have varied experiences with counterterrorism and homeland security issues. The research team conducted on-site, in-depth interviews with personnel involved in developing or implementing counterterrorism or homeland security functions within their respective agency. The research team used a standardized interview protocol to address such issues as security operations, regional role, organizational structures, challenges associated with the focus on counterterrorism and homeland security issues, information sharing, training, equipment, and grant funding.

This study, funded under the Measuring What Matters Program, was conducted to identify general neighborhood strengthening, or community building, processes and police contributions to them. The purpose of the study, also known as the Police-Community Interaction Project (PCIP), was to conceive, identify, or define recognizable patterns of interaction and to find ways to treat these as quantities that vary in amount and can be shown to fluctuate over time or across places. To that end, researchers conducted surveys of block clubs, neighborhood associations, and umbrella groups to gauge the issues that were important to them, steps they were taking to address these issues, and the ways in which they interacted with the police. Researchers also attended the meetings and events held by the Westside Cooperative Organization (WESCO), an umbrella group, and gathered coded data about the meetings, events and issues discussed. Specific variables in the study include demographic variables about the blocks, neighborhoods, and districts represented by the organizations, descriptive variables on the organizations themselves, variables describing issues of importance to the organizations and steps those organizations were taking to address the issues, variables to describe the interaction between the organizations and police, and variables describing police involvement in community activities.

Multi-Method Study of Police Special Weapons and Tactics Teams in the United States, 1986-1998 (ICPSR 20351)
Released/updated on: 2007-12-10
Geographic coverage: United States
Time period: 1986-01-01--1998-01-01
This research study was designed to pursue three specific goals to accomplish its objective of enhancing knowledge about Special Weapons and Tactics (SWAT) teams and the role they play in contemporary American policing. The first goal was to develop a better picture of the structure and nature of SWAT teams in American law enforcement. The second goal of the research project was to increase the amount of knowledge about how SWAT teams prepare for and execute operations. The project's third goal was to develop information about one specific aspect of SWAT operations: the use of force, especially deadly force, by both officers and suspects. To gather this information, the SWAT Operations Survey (SOS) was conducted. This was a nationwide survey of law enforcement agencies with 50 or more sworn officers. The survey sought information about the agencies' emergency response capabilities and structures. The SOS included two instruments: (1) the Operations Form, completed by a total of 341 agencies, and containing variables about the organization and functioning of SWAT teams, and (2) the Firearms Discharge Report, which includes a total of 273 shootings of interest, as well as items about incidents in which SWAT officers and suspects discharged firearms during SWAT operations.

National Assessment Program Survey of Criminal Justice Agencies in the United States, 1992-1994 (ICPSR 6481)
Released/updated on: 2005-11-04
Geographic coverage: United States
Time period: 1992-01-01--1994-01-01
The National Assessment Program (NAP) Survey was conducted to determine the needs and problems of state and local criminal justice agencies. At the local level in each sampled county, survey questionnaires were distributed to police chiefs of the largest city, sheriffs, jail administrators, prosecutors, public defenders, chief trial court judges, trial court administrators (where applicable), and probation and parole agency heads. Data were collected at the state level through surveys sent to attorneys general, commissioners of corrections, prison wardens, state court administrators, and directors of probation and parole. For the 1992-1994 survey, 13 separate questionnaires were used. Police chiefs and sheriffs received the same survey instruments, with a screening procedure employed to identify sheriffs who handled law enforcement responsibilities. Of the 411 counties selected, 264 counties also employed trial court administrators. Judges and trial court administrators received identical survey instruments. A total of 546 surveys were mailed to probation and parole agencies, with the same questions asked of state and local officers. Counties that had separate agencies for probation and parole were sent two surveys. All survey instruments were divided into sections on workload (except that the wardens, jail administrators, and corrections commissioners were sent a section on jail use and crowding instead), staffing, operations and procedures, and background. The staffing section of each survey queried respondents on recruitment, retention, training, and number of staff. The other sections varied from instrument to instrument, with questions tailored to the responsibilities of the particular agency. Most of the questionnaires asked about use of automated information systems, programs, policies, or aspects of the facility or security needing improvement, agency responsibilities and jurisdictions, factors contributing to workload increases, budget, number of fulltime employees and other staff, and contracted services. Questions specific to police chiefs and sheriffs included activities aimed at drug problems and whether they anticipated increases in authorized strength in officers. Jail administrators, corrections commissioners, and wardens were asked about factors contributing to jail crowding, alternatives to jail, medical services offered, drug testing and drug-related admissions, and inmate classification. Topics covered by the surveys for prosecutors, public defenders, judges, and state and trial court administrators included types of cases handled, case timeliness, diversion and sentencing alternatives, and court and jury management. State and local probation and parole agency directors were asked about diagnostic tools, contracted services, and drug testing. Attorneys general were queried about operational issues, statutory authority, and legal services and support provided to state and local criminal justice agencies.

Time period: 2019-10-01--2020-09-01, 2020-10-01--2021-09-01, 2021-10-01--2022-09-01
The Office of Juvenile Justice and Delinquency Prevention (OJJDP)'s Internet Crimes Against Children (ICAC) Training and Technical Assistance (TTA) Program provides TTA to ICAC task force members and their affiliate agencies to support the investigation of ICAC cases. However, little is known about the quality, implementation fidelity, outcomes, and costs associated with ICAC TTA Program training. This study was designed to fill this gap and focused on examining the quality, implementation fidelity, and costs of OJJDP-funded ICAC trainings, as well as participant reactions to training such as perceptions of quality and satisfaction, perceived changes in knowledge and skills, and perceived training results. Using a descriptive design, this study used multiple data collection and analysis approaches, including those that involved extant data collected by TTA providers (i.e., surveys, pre-post tests, implementation data, cost data) and original data collected by the evaluation team (i.e., observations, surveys, interviews, cost data). Findings suggest that overall, ICAC investigative training was rated highly by both trainees and their ICAC commanders in terms of the quality of training delivery, expertise of instructors, knowledge gains, and applicability to on-the-job ICAC investigations. Costs associated with ICAC training suggest a total cost of about $10.3 million to provide ICAC training over the three-year evaluation period, with annual average costs ranging from $2.9 million to $4.3 million over this period. Findings from this study are intended to support OJJDP in its understanding of the ICAC TTA Program to develop and deliver investigative TTA to ICAC task forces.

National Manpower Survey, 1973-1976 (ICPSR 7675)
Released/updated on: 1992-02-16
Geographic coverage: United States
Time period: 1973-01-01--1976-01-01
This data collection contains information from a series of national surveys, conducted simultaneously across the criminal justice system, to ascertain national manpower strengths and goals, agency information and characteristics, and attitudes of the agency heads during the period 1973-1976. The National Manpower Survey was undertaken to assess the adequacy of existing federal, state, and local training and education programs meeting current personnel needs in various law enforcement and criminal justice functions and operations. The study intended to project future personnel and training needs, by occupation, in relation to anticipated availability of qualified personnel in order to assess the future adequacy of training and educational resources. It also sought to establish "needs priorities" as a basis for future training and academic assistance programs to be funded by the Bureau of Justice Statistics. The study design systematically covered the personnel needs in all state and local governmental agencies that were part of the law enforcement and criminal justice system. Sectors within the system included: (1) law enforcement, consisting of police departments and sheriff's agencies, ranging in size from one-person constabularies to large city departments employing 20,000 or more individuals, (2) corrections, including both adult and juvenile correctional institutions and agencies, and (3) the judicial process, including a wide range of courts with varying jurisdictions and scope, district attorneys or prosecutors' offices, and public defenders' offices. For this study, the Bureau of Social Science Research was responsible for the acquisition and assessment of existing statistical data as well as the design and execution of systematic mail surveys of agencies, officials, and employees within the law enforcement/criminal justice system. Nine nationwide surveys were directed to executives in criminal justice agencies, including chiefs of police (in both large and small departments), sheriffs (in both large and small departments), chief prosecutors, chief defenders, court administrators, wardens of adult correctional facilities, directors of juvenile correctional facilities, and chief probation and parole officers. Two additional surveys were sent to general and appellate jurisdiction courts. In the nine surveys directed to criminal justice executives, the instruments asked respondents for (1) an overall assessment of manpower problems, including personnel categories in which critical shortages might exist, and total personnel required to fulfill all agency duties and responsibilities, (2) desired and actual entry level standards, as well as entry level and in-service training content and requirements, (3) demographic, educational, training, and occupational background information about the executive respondent, (4) opinions about major obstacles to effectiveness and attitudes toward various issues such as team policing, plea bargaining, and computer-assisted case management, and (5) a fact sheet section dealing with agency employment by occupational category, salaries, and workloads. Each of the remaining two surveys was a census of general and appellate jurisdiction courts designed to yield basic statistical information regarding the courts and court systems' current staffing, training activities, and caseloads, and did not seek any attitudinal or subjective responses. Thus the agency itself was the reporting unit, with the respondent required only to be in a position to provide accurate, reliable information.

National Review of Stalking Laws and Implementation Practices in the United States, 1998-2001 (ICPSR 3411)
Released/updated on: 2006-03-30
Geographic coverage: United States
Time period: 1998-01-01--2001-01-01
This study was designed to clarify the status of stalking laws and their implementation needs. To accomplish this, the principal investigator conducted a survey of police and prosecutor agencies across the country to determine how stalking laws were being implemented. While there had been significant federal support for state and local agencies to adopt anti-stalking laws and implement anti-stalking initiatives, no comprehensive review of the status of such efforts had been done. Thus, there had been no way of knowing what additional measures might be needed to enhance local anti-stalking efforts. Two national surveys on stalking were conducted. The first survey of 204 law enforcement agencies (Part 1, Initial Law Enforcement Survey Data) and 222 prosecution offices (Part 3, Initial Prosecutor Survey Data) in jurisdictions with populations over 250,000 was conducted by mail in November of 1998. The survey briefly asked what special efforts the agencies had undertaken against stalking, including special units, training, or written policies and procedures. A replication of the first national survey was conducted in November of 2000. Part 2, Follow-Up Law Enforcement Survey Data, contains the follow-up data for law enforcement agencies and Part 4, Follow-Up Prosecutor Survey Data, contains the second survey data for prosecutors. Parts 1 to 4 include variables about the unit that handled stalking cases, types of stalking training provided, written policies on stalking cases, and whether statistics were collected on stalking and harassment. Parts 2 and 4 also include variables about the type of funding received by agencies. Part 4 also contains variables about other charges that might be filed in stalking cases, such as harassment, threats, criminal trespass, and protection order violation.

National Survey of Staffing Issues in Large Police Agencies, 2006-2007 [United States] (ICPSR 29162)
Released/updated on: 2012-10-26
Geographic coverage: United States
Time period: 2006-01-01--2007-01-01
The primary objective of this study was to formulate evidence-based lessons on recruitment, retention, and managing workforce profiles in large, United States police departments. The research team conducted a national survey of all United States municipal police agencies that had at least 300 sworn officers and were listed in the 2007 National Directory of Law Enforcement Administrators. The survey instrument was developed based on the research team's experience in working with large personnel systems, instruments used in previous police staffing surveys, and discussions with police practitioners. The research team distributed the initial surveys on February 27, 2008. To ensure an acceptable response rate, the principal investigators developed a comprehensive nonresponse protocol, provided ample field time for departments to compile information and respond, and provided significant one-on-one technical assistance to agencies as they completed the survey. In all, the surveys were in the field for 38 weeks. Respondents were asked to consult their agency's records in order to provide information about their agency's experience with recruiting, hiring, and retaining officers for 2006 and 2007. Of the 146 departments contacted, 107 completed the survey. The police recruitment and retention survey data were supplemented with data on each jurisdiction from the American Community Survey conducted by the United States Census Bureau, the Bureau of Labor Statistics, and the Federal Bureau of Investigation Uniform Crime Reports. The dataset contains a total of 535 variables pertaining to recruitment, hiring, union activity, compensation rates, promotion, retirement, and attrition. Many of these variables are available by rank, sex and race.

Police Use of Force [United States]: Official Reports, Citizen Complaints, and Legal Consequences, 1991-1992 (ICPSR 6274)
Released/updated on: 1996-07-13
Geographic coverage: United States
Time period: 1991-01-01--1992-01-01
This national survey was designed to collect information on police departmental policies and practices pertaining to the use of physical force--both deadly and less than lethal--by law enforcement officers. A further objective was to investigate the enforcement of these policies by examining the extent to which complaints of policy violations were reviewed and violations punished. Additionally, the survey sought to determine the extent to which departments kept records on the use of force, and to collect from those agencies that recorded this information data relating to how frequently officers used force, the characteristics of officers who did and did not have complaints filed against them, and the training of recruits on the appropriate use of force. The study also provides data on citizen complaints of excessive force, the disposition of those complaints, and litigation concerning allegations of excessive force. Additional variables provide agency size, demographic characteristics, and workload.

Role of Police Psychology in Controlling Excessive Force in 50 Large Cities in the United States, 1992 (ICPSR 6402)
Released/updated on: 1996-10-01
Geographic coverage: United States
As part of the development of an information base for subsequent policy initiatives, the National Institute of Justice sponsored a nationwide survey of police psychologists to learn more about the characteristics of officers who abuse force, the types of measures police psychologists recommend to control police violence and the role of police psychologists in preventing and identifying individual police officers at risk for use of excessive force. Police personnel divisions in 50 large cities were contacted for names and addresses of the police psychologists who provided services to their departments. Data were collected using a telephone interview protocol that included 61 questions. In this study, excessive force was defined as a violation of a police department's use-of-force policy by an incumbent officer that was serious enough to warrant a referral to the police psychologist. Background information collected on respondents included years with the department, years as a police psychologist, if the position was salaried or consultant, and how often the psychologist met with the police chief. A battery of questions pertaining to screening was asked, including whether the psychologist performed pre-employment psychological screening and what methods were used to identify job candidates with a propensity to use excessive force. Questions regarding monitoring procedures asked if and how police officer behavior was monitored and if incumbent officers were tested for propensity to use excessive force. Items concerning police training included which officers the psychologist trained, what types of training covering excessive force were conducted, and what modules should be included in training to reduce excessive force. Information about mental health services was elicited, with questions on whether the psychologist counseled officers charged with excessive force, what models were used, how the psychologist knew if the intervention had been successful, what factors limited the effectiveness of counseling police officers, characteristics of officers prone to use excessive force, how these officers are best identified, and who or what has the most influence on these officers. General opinion questions asked about factors that increase excessive force behavior and what services could be utilized to reduce excessive force.

Social Interaction Training to Reduce Police Use of Force, Fayetteville, NC and Tucson, AZ, 2016-2018 (ICPSR 37856)
Released/updated on: 2022-11-10
Geographic coverage: North Carolina, Fayetteville, United States, Tucson, Arizona
Time period: 2016-01-01--2018-01-01
This study evaluated Polis Solution's Tact, Tactics, and Trust (T3) program using a randomized controlled trial (RCT). Survey data were collected from experimental and control group officers at two research sites prior to and after the implementation of the training program. Additionally, official use of force reports from both agencies were collected from roughly one year prior to the implementation of the training program to one year after the completion of the training program. The survey data are used to examine changes in officers' attitudes and priorities during hypothetical officer-citizen encounters to determine if the training program impacted the importance officers placed on specific social interaction concerns. The use of force reports were then used to determine whether the training program successfully reduced the number of use of force incidents among officers involved in the training program.

Victims' Ratings of Police Services in New York and Texas, 1994-1995 Survey (ICPSR 6787)
Released/updated on: 2005-11-04
Geographic coverage: New York, United States, Texas
Time period: 1994-12-01--1995-03-01
The Family Violence Prevention and Services Act of 1984 (FVPSA) provided funding, through the Office of Victims of Crime in the United States Department of Justice, for 23 law enforcement training projects across the nation from 1986 to 1992. FVPSA was enacted to assist states in (1) developing and maintaining programs for the prevention of family violence and for the provision of shelter to victims and their dependents and (2) providing training and technical assistance for personnel who provide services for victims of family violence. The National Institute of Justice awarded a grant to the Urban Institute in late 1992 to evaluate the police training projects. One of the program evaluation methods the Urban Institute used was to conduct surveys of victims in New York and Texas. The primary objectives of the survey were to find out, from victims who had contact with law enforcement officers in the pre-training period and/or in the post-training period, what their experiences and evaluations of law enforcement services were, how police interventions had changed over time, and how the quality of services and changes related to the police training funded under the FVPSA. Following the conclusion of training, victims of domestic assault in New York and Texas were surveyed through victim service programs across each state. Similar, but not identical, instruments were used at the two sites. Service providers were asked to distribute the questionnaires to victims of physical or sexual abuse who had contact with law enforcement officers. The survey instruments were developed to obtain information and victim perceptions of the following key subject areas: history of abuse, characteristics of the victim-abuser relationship, demographic characteristics of the abuser and the victim, history of law enforcement contacts, services received from law enforcement officers, and victims' evaluations of these services. Variables on history of abuse include types of abuse experienced, first and last time physically or sexually abused, and frequency of abuse. Characteristics of the victim-abuser relationship include length of involvement with the abuser, living arrangement and relationship status at time of last abuse, number of children the victim had, and number of children at home at the time of last abuse. Demographic variables provide age, race/ethnicity, employment status, and education level of the abuser and the victim. Variables on the history of law enforcement contacts and services received include number of times law enforcement officers were called because of assaults on the victim, number of times law enforcement officers actually came to the scene, first and last time officers came to the scene, number of times officers were involved because of assaults on the victim, number of times officers were involved in the last 12 months, and type of law enforcement agencies the officers were from. Data are also included on city size by population, city median household income, county population density, county crime rate, and region of state of the responding law enforcement agencies. Over 30 variables record the victims' evaluations of the officers' responsiveness, helpfulness, and attitudes.

Work and Family Services for Law Enforcement Personnel in the United States, 1995 (ICPSR 2696)
Released/updated on: 2006-03-30
Geographic coverage: United States
This study was undertaken to provide current information on work and family issues from the police officer's perspective, and to explore the existence and prevalence of work and family training and intervention programs offered nationally by law enforcement agencies. Three different surveys were employed to collect data for this study. First, a pilot study was conducted in which a questionnaire, designed to elicit information on work and family issues in law enforcement, was distributed to 1,800 law enforcement officers representing 21 municipal, suburban, and rural police agencies in western New York State (Part 1). Demographic information in this Work and Family Issues in Law Enforcement (WFILE) questionnaire included the age, gender, ethnicity, marital status, highest level of education, and number of years in law enforcement of each respondent. Respondents also provided information on which agency they were from, their job title, and the number of children and step-children they had. The remaining items on the WFILE questionnaire fell into one of the following categories: (1) work and family orientation, (2) work and family issues, (3) job's influence on spouse/significant other, (4) support by spouse/significant other, (5) influence of parental role on the job, (6) job's influence on relationship with children, (7) job's influence on relationships and friendships, (8) knowledge of programs to assist with work and family issues, (9) willingness to use programs to assist with work and family issues, (10) department's ability to assist officers with work and family issues, and (11) relationship with officer's partner. Second, a Police Officer Questionnaire (POQ) was developed based on the results obtained from the pilot study. The POQ was sent to over 4,400 officers in police agencies in three geographical locations: the Northeast (New York City, New York, and surrounding areas), the Midwest (Minneapolis, Minnesota, and surrounding areas), and the Southwest (Dallas, Texas, and surrounding areas) (Part 2). Respondents were asked questions measuring their health, exercise, alcohol and tobacco use, overall job stress, and the number of health-related stress symptoms experienced within the last month. Other questions from the POQ addressed issues of concern to the Police Research and Education Project -- a sister organization of the National Association of Police Organizations -- and its membership. These questions dealt with collective bargaining, the Law Enforcement Officer's Bill of Rights, residency requirements, and high-speed pursuit policies and procedures. Demographic variables included gender, age, ethnicity, marital status, highest level of education, and number of years employed in law enforcement. Third, to identify the extent and nature of services that law enforcement agencies provided for officers and their family members, an Agency Questionnaire (AQ) was developed (Part 3). The AQ survey was developed based on information collected from previous research efforts, the Violent Crime Control and Law Enforcement Act of 1994 (Part W-Family Support, subsection 2303 [b]), and from information gained from the POQ. Data collected from the AQ consisted of whether the agency had a mission statement, provided any type of mental health service, and had a formalized psychological services unit. Respondents also provided information on the number of sworn officers in their agency and the gender of the officers. The remaining questions requested information on service providers, types of services provided, agencies' obstacles to use of services, agencies' enhancement of services, and the organizational impact of the services.
