Developing, Implementing, and Evaluating a Police Fatigue Risk-Management Strategy for the Seattle Police Department, Washington, 2020-2023 (ICPSR 39029)

Released/updated on: 2025-07-10
Geographic coverage: Seattle, United States, Washington
Time period: 2020-01-01--2023-01-01

The goal of the project was to improve police officers' sleep, health, safety, and wellness, thus improving the quality of police services. Using a multi-phase, mixed method approach, the core objectives included:

  1. Measure the effects of work schedules and sleep loss on Seattle Police Department (SPD) officer health, wellness, safety, and quality of life.

  2. Develop a fatigue risk management strategy, informed by the data collected during objective one.

  3. Using a randomized control trial design, implement the resulting fatigue risk management strategy across the SPD, which is a large municipal police department (approximately 1,500 sworn officers)

  4. Measure the effectiveness of the fatigue risk management strategy.

The main research questions the study sought to address were as follows:

  1. What are the effects of shift work, work hours, sleep loss, and fatigue on police officers' safety, health, and quality of life?

  2. Can a fatigue risk management strategy influence these effects?

Variables include measures of officers' sleep patterns and sleep quality, physical and mental health metrics, descriptions of the officers' role at the SPD, and demographic variables including age, gender, and race/ethnicity.

Evaluation of Simulation vs. Classroom-Based Implicit Bias Training to Improve Police Decision Making and Enhance the Outcomes of Police-Citizen Encounters, California, 2019-2021 (ICPSR 39309)

Released/updated on: 2025-06-12
Geographic coverage: United States, California
Time period: 2019-01-01--2021-01-01
This study evaluated the impact of implicit bias and counter bias training interventions for improving police behavior and public perceptions of bias. A random selection of Body Worn Camera (BWC) videos from a large and diverse municipal agency were scored before and after training using a validated tool for coding police behavior. The variables coded from BWC videos were compiled into Body Worn Camera Data (DS1) and include demographic details on citizens and officers, circumstances of the incident, and the behavior of both the officer and citizen. During pre- and post- intervention measurement periods, "discrimination"-based community member complaints were also collected. Information about these complaints including the type, incident date, and complaint findings was compiled into Complaints Data (DS2).
