Anti-Terror Lessons of American Muslim Communities in Buffalo, New York, Houston, Texas, Raleigh-Durham, North Carolina, and Seattle, Washington, 2008-2009 (ICPSR 26921)
In the aftermath of the attacks on September 11, 2001, and subsequent terrorist attacks elsewhere around the world, a key counterterrorism concern was the possible radicalization of Muslims living in the United States. The purpose of the study was to examine and identify characteristics and practices of four American Muslim communities that have experienced varying levels of radicalization. The communities were selected because they were home to Muslim-Americans that had experienced isolated instances of radicalization. They were located in four distinct regions of the United States, and they each had distinctive histories and patterns of ethnic diversity.
This objective was mainly pursued through interviews of over 120 Muslims located within four different Muslim-American communities across the country (Buffalo, New York; Houston, Texas; Seattle, Washington; and Raleigh-Durham, North Carolina), a comprehensive review of studies an literature on Muslim-American communities, a review of websites and publications of Muslim-American organizations and a compilation of data on prosecutions of Muslim-Americans on violent terrorism-related offenses.

Eyewitness Identification: A Systematic Investigation of Lineup Composition and Fairness, United States, 2019-2022 (ICPSR 38761)
The major objective of this project was to investigate photo array composition in order to improve eyewitness identification procedures. Photo array composition involves the fillers, or known-innocent individuals that police add to a photo array so that the perpetrator/suspect (referred to as the "target" in experimental design) does not stand out. An unbiased (fair) photo array contains fillers that match the description of the suspect provided by one or more eyewitnesses. In contrast, in a biased photo array, the suspect stands out from the fillers. Another popular procedure used by police is the showup, when the suspect is presented without any fillers. This project involved all three of these procedures.
This collection contains raw and aggregated data from 12 sets of experiments that investigated different aspects of eyewitness identification, including fair vs. biased lineups, lineup size, distinctive facial features, target-filler similarity, impact of sleep on eyewitness accuracy, memory strength, number of suspects presented, impact of courtroom instructions and expert expertise, and speed and confidence of eyewitness identification. Each experiment set followed a similar general design, with variations based on the purpose and hypotheses of the specific study. United States-based adult participants recruited via SurveyMonkey were asked to complete an online experiment in which they would be presented with a crime vignette and a suspect facial image (created from a faces database), given a distractor task, and then asked to select the suspect from a lineup and rate the confidence level of their decision.
The data were provided to ICPSR in Excel workbook format (41 data files, 3 codebooks) and are available for download as a zipped package. ICPSR has not modified the files from the format in which they were supplied. Data files are organized into subfolders that are named with a short content descriptor and citation of the relevant publication. Unless noted, data files contain a "codes" sheet that explains the variables and experimental condition groups. Articles and theses/dissertations that used each dataset are available under Data-related Publications. Please refer to the ICPSR README for more information.
The Healthy Adolescent Relationship Trajectories (HART) Study, Baltimore, Maryland, 2018-2021 (ICPSR 38273)
Teen dating violence (TDV) is a prevalent criminal justice problem. The field urgently needs more effective interventions that are relevant to the lives of diverse adolescents; developing these interventions requires understanding of how violent episodes unfold within the greater romantic context, which generally includes not only violence but also positive feelings and behaviors. This study recruited 144 urban, primarily African American adolescent females from disadvantaged communities between 16 and 19 years of age who reported being in a romantic relationship with TDV in the past month.
The objectives of this study include examining the inter-play between emotional connectedness, pro-relationship behaviors, jealousy and TDV victimization and perpetration. Specifically, researchers will (1A) determine the same day and previous day associations between adolescent females' perceptions of emotional connectedness (love, communication, dyadic trust, intimate self-disclosure, commitment and enmeshment), jealousy and TDV victimization and perpetration, (1B) compare the frequency and patterns of emotional connectedness and jealousy across relationships that initiate, continue and/or escalate TDV victimization and perpetration; (2A) determine the same day and previous day associations between adolescent females' reports of pro-relationship behaviors and TDV victimization and perpetration, (2B) compare the frequency and patterns of pro-relationship behaviors across relationships that initiate, continue and/or escalate TDV victimization and perpetration; and (3) determine cycles of rupture (TDV incidents) and repair within adolescent relationships over time.
Researchers leveraged the infrastructure from the prior NIJ grant to recruit participants from community venues in Baltimore that have been identified as locations where adolescent females congregate, as well as recruited in the Johns Hopkins Pediatric Emergency Department and online through social media posts. Eligible females with informed consent completed the baseline survey which includes socio-demographic questions about the participant and her partner. From baseline, participants completed four months of diaries by responding to daily web-based questions on their Smart Phone about TDV victimization and perpetration, emotional connectedness and pro-relationship behaviors.
Homeland Security in Small Law Enforcement Jurisdictions: Preparedness, Efficacy, and Proximity to Big-City Peers, 2011 (ICPSR 33941)
The Homeland Security in Small Law Enforcement Jurisdictions study drew upon data collected from 350 small (1-25 full time sworn officers) law enforcement agencies nationwide to address four gaps in the homeland security research literature and clarify/expand upon an empirically-derived model of homeland security preparedness and organizational efficacy.
- Whether physical and relational proximity to large agency peers facilitates the development of homeland security preparedness and improves perceptions of organizational efficacy (the capacity of an organization to respond) in small agencies and, conversely, whether the geographic isolation of small, rural agencies inhibits homeland security efforts.
- Whether efficacy of efforts to enhance homeland security is not just a function of perceived/actual risk or funding, but also other "institutional pressures", such as books and journal publications, as well as conferences, training, and other professional networks and channels.
- Assessments of preparedness outcomes through "organizational efficacy", the perception about the organization's ability to accomplish its goals.
- The lack of theoretical context, such as contingency and institutional theory frameworks, used to examine data on preparedness and organizational efficacy.
Jurors' Judgments About Forensic Identification Evidence, Arizona, 2011-2014 (ICPSR 36169)
This data file describes three different experiments that were designed to examine how differences in the way forensic scientific evidence is communicated affects jurors.
In each experiment, participants consisted of jury-eligible community members in Maricopa County, Arizona. Groups of participants attended a research session in which they were shown a 35-40-minute videotapes of one of two mock criminal trials (one, a rape case, centers around bitemark evidence, and the other, an attempted murder, centers around fingerprint evidence). Within each trial the content of a forensic scientist's testimony was manipulated. These manipulations involved: 1) whether the technique used by the forensic scientist was "high tech" or "low tech," 2) the amount of experience possessed by the forensic scientist, 3) whether the technique used by the forensic scientist had been scientifically validated, 4) whether the forensic scientist conceded that an error was possible, and 5) whether any exculpatory evidence was present at the crime scene.
Immediately following the trial, each individual participants completed a questionnaire in which they gave their individual impressions of the strength of the case. Following that, the group of participant would deliberate and attempt to reach a unanimous verdict. Finally, each individual participant completed an additional questionnaire that again measured perceptions of the case along with individual difference measures and demographics.

Tribal Justice, Tribal Court: Strengthening Tribal Justice Systems Using Restorative Approaches, South Dakota, 2022 (ICPSR 38825)
The purpose of this project was to develop a culturally relevant crime seriousness index specific to the Sisseton-Wahpeton Oyate (SWO) tribe while working closely with community partners. Informal background interviews with key stakeholders provided a foundation on traditional crime management by the community. These interviews informed the creation of an SWO-specific adaptation of the Sellin-Wolfgang crime seriousness index following an online survey conducted in 2022 with SWO community members (n=44 completed surveys).
Aggregated survey data have been released as a zipped package as it was received by ICPSR. Please refer to the study documentation for details on the index items and instructions on how to obtain the raw research data. The Final Report released by NIJ contains the full SRO crime seriousness index as Appendix D.
