Abstract: This Campbell systematic review assesses the effects of problem‐oriented policing on crime and disorder based on the existing research. The review summarises findings from 10 studies from eight American cities and six residential areas in the UK. The participants were probationers, parolees and residents of the eight American cities and six residential areas in the UK. Problem oriented policing has a statistically significant impact on reducing crime and disorder, but the effect size was small, and there was a lack of diversity and responses in the included studies. The results were similar for both the randomized and quasi‐randomized studies. The evidence base is small and there are shortcomings in the quality of the evidence. Abstract Background: Problem‐oriented Policing (POP) was first introduced by Herman Goldstein in 1979. The approach was one of a series of responses to a crisis in effectiveness and legitimacy in policing that emerged in the 1970s and 1980s. Goldstein argued that police were not being effective in preventing and controlling crime because they had become too focused on the “means” of policing and had neglected the “goals” of preventing and controlling crime and other community problems. Goldstein argued that the unit of analysis in policing must become the “problem” rather than calls or crime incidents as was the case during that period. POP has had tremendous impact on American policing, and is now one of the most widely implemented policing strategies in the US. Objectives: To synthesize the extant problem‐oriented policing evaluation literature and assess the effects of problem‐oriented policing on crime and disorder Selection criteria: Eligible studies had to meet three criteria: (1) the SARA model was used for a problem‐oriented policing intervention; (2) a comparison group was included; (3) at least one crime or disorder outcome was reported with sufficient data to generate an effect size. The unit of analysis could be people or places. Search strategy: Several strategies were used to perform an exhaustive search for literature fitting the eligibility criteria. First, a keyword search was performed on an array of online abstract databases. Second, we reviewed the bibliographies of past reviews of problem‐oriented policing. Third, we performed forward searches for works that have cited seminal problem‐oriented policing studies. Fourth, we performed hand searches of leading journals in the field. Fifth, we searched the publications of several research and professional agencies. Sixth, after finishing the above searches we e‐mailed the list of studies meeting our eligibility criteria to leading policing scholars knowledgeable in the area of problem‐oriented policing to ensure we had not missed any relevant studies. Data collection and analysis: For our ten eligible studies, we provide both a narrative review of effectiveness and a meta‐analysis. For the meta‐analysis, we coded all primary outcomes of the eligible studies and we report the mean effect size (for studies with more than one primary outcome, we averaged effects to create a mean), the largest effect, and the smallest effect. Because of the heterogeneity of our studies, we used a random effects model. Main results: Based on our meta‐analysis, overall problem‐oriented policing has a modest but statistically significant impact on reducing crime and disorder. Our results are consistent when examining both experimental and quasi‐experimental studies. Conclusions: We conclude that problem‐oriented policing is effective in reducing crime and disorder, although the effect is fairly modest. We urge caution in interpreting these results because of the small number of methodologically rigorous studies on POP and the diversity of problems and responses used in our eligible studies.
