This Campbell systematic review examines the effects police‐initiated diversion programs on delinquent behavior, compared to traditional system processing. The review summarizes evidence from nineteen high‐quality studies, including 13 randomized controlled trials and six quasi‐experimental studies. This review includes studies that evaluated the effects of police‐led diversionary practices compared to traditional processing for youth under 18 years of age. We identified a total of 14 manuscripts representing 19 evaluations. Of these 19 evaluations, 13 used randomized controlled designs (random assignment to conditions) and 6 used quasi‐experimental designs (no random assignment to conditions). Many of these designs included two or more diversionary conditions compared to a common control (traditional processing) producing 31 treatment‐comparison contrasts for analysis. These studies were conducted between 1973 and 2011, inclusively. Most were conducted in the USA (11) with the remaining conducted in Canada (4), Australia (2), and the UK (2). The general pattern of evidence is positive, suggesting that police‐led diversion reduces the future delinquent behavior of low‐risk youth relative to traditional processing. Assuming a 50 percent reoffending rate for the traditional processing condition, the results suggest a reoffending rate of roughly 44 percent for the diverted youth. This overall benefit of diversion holds for the random assignment studies judged to be free from any obvious risks of bias. No meaningful differences were found across types of diversionary programs. Furthermore, we found no evidence to suggest these findings suffer from publication selection bias. Plain language summary Police‐led diversion of low‐risk youth reduces their future contact with the justice systemPolice‐led diversion of low‐risk youth who come into contact with the justice system is more effective in reducing a youth's future contact with the justice system compared to traditional processing. What is this review about?Youth misconduct and misbehavior is a normal part of adolescence and that misbehavior sometimes crosses the line from disruptive or problematic to delinquent. Nationally representative surveys of youth in the USA have indicated that minor delinquent behavior is normative, particularly for boys. The normative nature of minor delinquent behavior raises the question of how police should respond to minor delinquent behavior in a way that is corrective, but also avoids involving the youth in the criminal justice system beyond what will be effective in reducing future misbehavior.Police diversion schemes are a collection of strategies police can apply as an alternative to court processing of youth. Diversion as an option is popular among law enforcement officers, as it provides an option between ignoring youth engaged in minor wrongdoing and formally charging such youth with a crime. Police‐led diversion has the potential to reduce reoffending by limiting the exposure of low‐risk youth to potentially harmful effects of...

Executive Summary/Abstract Background Survey research and analysis of police records, hospital emergency rooms, and women's shelters have clearly established the severity of the intimate partner violence problem and the need to find programs to address this issue. Roughly 1 in 4 women in an intimate relationship is a victim of intimate partner violence. Court‐mandated batterer intervention programs (BIPs) have been implemented throughout the United States as a leading method to address this problem. These programs are also now implemented in Canada and Europe. These programs emerged from the women's shelter movement leading to programs with a strong feminist orientation, such as the Duluth Model. The programs that were developed were group‐based and relied on psychoeducational methods. Their aim was to get men to take responsibility for their sexist beliefs and stop abusing their partners by teaching them alternative responses for handling their anger. More recent programs draw from cognitive‐behavioral therapeutic principles or a mix of the latter with feminist components as well. Objectives This is an update of our prior review. The aim was to assess the effects of postarrest court‐mandated interventions for intimate partner violence offenders that target, in part or exclusively, male batterers. Our focus was on studies aimed at reducing intimate partner violence, above and beyond what would have been expected by routine legal procedures (e.g., probation monitoring, etc.). Search Methods We searched numerous databases and websites, bibliographies of published reviews of related literature, and a scrutiny of annotated bibliographies of related literature. Our goal was to identify all published and unpublished literature that met our selection criteria. The original review identified nine eligible studies. The updated search identified two new studies. The total sample size across these 11 studies was 4824. Selection Criteria We included experimental (random assignment) and quasi‐experimental evaluations of court‐mandated BIPs that measured official or victim reports of future intimate partner violence. Rigorous quasi‐experimental designs were defined as those that either used matching or statistical controls to improve the comparability of the treated (program) and untreated (comparison) groups. The original review also included quasi‐experimental designs that used treatment drop‐outs as the comparison group. Given the serious selection bias of such studies, these have not been included in this update. Data Collection and Analysis We coded characteristics of the treatment, sample, outcomes, and research methods. Findings were extracted in the form of an effect size and effect sizes were analyzed using the inverse‐variance weight method of meta‐analysis. Official report and victim report outcomes were analyzed separately as were the different design types (i.e., random assignment and quasi‐experimental designs with a no treatment comparison). Results The mean effect for official reports of intimate partner violen...

The relationship between the police and African Americans has had a contentious history for decades. To explore this topic further, we interviewed 77 African Americans in the City of Durham, NC, about the declining relationship between their community and the police. We find that African Americans’ perceptions of the police are nuanced and complicated by personal experiences, vicarious experiences of relatives and friends, and news from social media and television regarding policing practices and treatment, including police harassment and/or brutality. We characterize these direct and vicarious experiences as the transmission of trauma. Even for the proportion of African Americans who had positive perceptions and interactions with the police, their views of the police seemed to be further complicated by broader concerns of discriminatory treatment. We proffer solutions to improve the relationship between the police and African Americans. The implications of our findings for future research are also discussed.
