---|---|---|---|
Portland, OR2014 | Through a multi-agency, collaborative effort, the Portland Police Bureau (PPB) worked in coordination with the Mayor’s Office, local academics, and community partners to reduce crime and build community relationships primarily through community engagement patrols (CEP). | Research Design Ninety high crime areas were randomly assigned to receive none, two, or four 15-minute supplemental CEPs a day for a three month period. Offense reports, CAD data, resident surveys, officer focus groups, and officer surveys were used to conduct process and outcome evaluations of the NI-Loc program. Findings

Roanoke County, VA2015 | The SPI evaluated the effects of mobile crisis team in an experimental context to enhance police response to people with mental illness. The intervention sought to understand and improve Roanoke County Police Department's response to calls for service (CFS) involving individuals experiencing mental health (MH) crises in Virginia’s primarily rural Roanoke Valley. | Research Design An experimental intervention testing the efficacy of a police-mental health provider co-responder model for addressing mental health-related calls for service.

Rochester, NY2012 | The Rochester SPI intervened in retaliatory gun violence.
| Research Design Examination of descriptive statistics, correlation coefficients, and logistic regression models. FindingsThe evaluation validated the risk assessment tool as a predictive device: for every one-point increase in the assessment tool score that a dispute received, the odds of violence occurring in that dispute over time increase by 29%. | Gun Violence, Violence Reduction |
Sacramento County, CA2016 | The Sacramento SPI implemented a Homeless Outreach Team (HOT). The overall objective of the SPI-HOT pilot was to develop a new service & community-oriented policing approach for addressing homelessness that de-emphasizes enforcement strategies. Three part-time deputies collaborated with various social services to provide street outreach services to individuals and families experiencing homelessness in select “hot spots” of the county – areas identified by Sheriff’s analysts and the research partner as having high levels of homelessness. | Research Design The intervention was intentioned to result in a series of staggered short-term and intermediate outcomes that would over time contribute to increase safety and collective efficacy in the community around issues of homelessness (the long-term impacts). The evaluation also conducted a process evaluation on implementation of HOT. Findings

Savannah, GA2009 | The Savannah SPI addressed increases in violent crime rates through the Savannah Impact Project (SIP), an intensive reentry and monitoring program focused on high-risk offenders.
| Research Design Pre-post impact analysis, assessment of service provision Findings16% reduction in violent crime at the Central Precinct (target area). Exploratory analyses found that providing services could reduce the likelihood of future crimes. Interviews concluded that SIP was effective because of the multi-agency collaboration and ability to balance treatment and enforcement approaches. | Violence Reduction |
Shoreline, WA2015 | This SPI developed the Response Awareness, De-Escalation, and Referral (RADAR) effort that was aimed to institutionalize department-wide and regional information sharing about community members with behavioral health issues or developmental disabilities (BH/DD) who may be at increased risk of violence or use of force; and offer opportunities for outreach and connection to services and resources through a mental health “navigator.” | Research Design A quasiexperimental design based on propensity score matching (PSM) methods in which RADAR response plan recipients would be matched with similarly-situated people in a comparison jurisdiction to compare outcomes accompanied by a process evaluation.

Toledo, OH2014 | The Toledo Police Department organized a prolific offender unit, entitled the Special Intelligence Group (SIG), consisting of one sergeant, four detectives, and a crime analyst. This unit was trained and equipped to gather intelligence and conduct undercover surveillance of prolific serious offenders. The research partners developed and tested an empirically based Prolific and Priority Offender (PPO) Scoring Matrix – a risk assessment tool for identifying those most at risk of committing a new robbery, burglary, or aggravated assault offense within the next year. | Research Design A quasi-experimental research design, examining the numbers of reported crimes within the geographic area identified as the “awareness space” of all of the prolific offenders as well examining reported crimes and calls for services within these areas. FindingsImplementation of the prolific offender program activities coincided with statistically significant reductions in the specific crimes targeted by the program.
