The purpose of this study is to examine the prevalence of police practitioner-research partnerships in the United States and examine the factors that prevent or facilitate development and sustainability of these partnerships. This study used a mixed method approach to examine the relationship between law enforcement in the United States and researchers. A nationally-representative sample of law enforcement agencies were randomly selected and given a survey in order to capture the prevalence of police practitioner-researcher partnerships and associated information. Then, representatives from 89 separate partnerships were interviewed, which were identified through the national survey. The primary purpose of these interviews was to gain insight into the barriers and facilitators of police and practitioner relationships as well as the benefits of this partnering. Lastly four case studies were conducted on model partnerships that were identified during interviews with practitioners and researchers.

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.
