Effects of Foot Patrol Policing in Boston, 1977-1985 (ICPSR 9351)

Released/updated on: 2006-01-12
Geographic coverage: United States, Massachusetts, Boston
Time period: 1977-01-01--1985-07-31
This collection evaluates the impact of a new foot patrol plan, implemented by the Boston Police Department, on incidents of crime and neighborhood disturbances. Part 1 contains information on service calls by types of criminal offenses such as murder, rape, aggravated assault, simple assault, robbery, larceny, burglary, and auto theft. It also contains data on types of community disturbances such as noisy party, gang, or minor disturbance and response priority of the incidents. Response priorities are classified according to a four-level scale: Priority 1: emergency calls including crimes in progress, high risk or personal injury, and medical emergencies, Priority 2: calls of intermediate urgency, Priority 3: calls not requiring immediate response, Priority 4: calls of undetermined priority. Parts 2 and 3 include information about patrol time used in each of the three daily shifts during the pre- and post-intervention periods. Part 4 presents information similar to Parts 2 and 3 but the data span a longer period of time--approximately seven years.

The purpose of the study was to implement a "platform-based" methodology for collecting data about police organizations and the communities they serve with the goals of generating in-depth standardized information about police organizations, personnel and practices and to help move policing in the direction of evidence-based "learning-organizations" by providing judicious feedback to police agencies and policy makers. The research team conducted three web-based Law Enforcement Organizations (LEO) surveys of sworn and civilian law enforcement employees (LEO Survey A Data, n=22,765; LEO Survey B Data, n=15,825; and LEO Survey C Data, n=16,483). The sample was drawn from the 2007 Law Enforcement Management and Administrative Statistics (LEMAS) database. Agencies with 100 to 3,000 sworn police personnel were eligible for participation. To collect data for the Police-Community Interaction (PCI) survey (PCI Data, n=16,659), each week department employees extracted names and addresses of persons who had recent contact with a police officer because of a reported crime incident, traffic accident or traffic stop. Typically, the surveys were completed within two to four weeks of the encounter.

National Police Research Platform, Phase I [United States], 2009-2011 (ICPSR 34518)

Released/updated on: 2016-08-31
Geographic coverage: United States
Time period: 2009-01-01--2011-12-31

The National Police Research Platform was designed to a) strengthen the science of policing by generating timely, in-depth, longitudinal information about policing organizations, personnel and practices and, b) move policing in the direction of evidence-based "learning organizations" by providing translational feedback to police agencies and policy makers. Phase I focused on testing methods and measures in 29 agencies in order to build the Platform infrastructure. First, a "total department" online methodology was successfully implemented covering numerous dimensions of organizational behavior, from supervision and accountability to employee integrity and burnout. Second, a public satisfaction contact survey was implemented in several jurisdictions to provide local external indicators of the quality of police-citizen encounters and organizational legitimacy in the community. Third, two longitudinal studies were initiated - one of new police recruits and one of new first-line supervisors - to chart their career development and identify factors that influence life trajectories. Finally, a randomized control trial was introduced in once site to test the effects of procedural justice training as part of the Platform's measurement system.

Psychological and Behavioral Effects of Bias- and Non-Bias-Motivated Assault in Boston, Massachusetts, 1992-1997 (ICPSR 3413)

Released/updated on: 2003-10-30
Geographic coverage: United States, Massachusetts, Boston
Time period: 1992-01-01--1997-12-31
This study sought to inform various issues related to the extent of victims' adverse psychological and behavioral reactions to aggravated assault differentiated by the offenders' bias or non-bias motives. The goals of the research included (1) identifying the individual and situational factors related to bias- and non-bias-motivated aggravated assault, (2) determining the comparative severity and duration of psychological after-effects attributed to the victimization experience, and (3) measuring the comparative extent of behavioral avoidance strategies of victims. Data were collected on all 560 cases from the Boston Police Department's Community Disorders Unit from 1992 to 1997 that involved victim of a bias-motivated aggravated assault. In addition, data were collected on a 10-percent stratified random sample of victims of non-bias assaults within the city of Boston from 1993 to 1997, resulting in another 544 cases. For each of the cases, information was collected from each police incident report. Additionally, the researchers attempted to contact each victim in the sample to participate in a survey about their victimization experiences. The victim questionnaires included questions in five general categories: (1) incident information, (2) police response, (3) prosecutor response, (4) personal impact of the crime, and (5) respondent's personal characteristics. Criminal history variables were also collected regarding the number and type of adult and juvenile arrest charges against offenders and victims, as well as dispositions and arraignment dates.
