Description: <jats:sec><jats:label /><jats:p>This Campbell systematic review examines why the implementation of preventive interventions to reduce youth involvement in gangs and gang crime may fail or succeed low and middle‐income countries. The review summarises findings from four studies conducted in Latin America and the Caribbean. These include findings from field observations and interviews with 63 former gang members in Guatemala, Honduras and El Salvador, 940 respondents in three Jamaican communities, 24 participants in Nicaragua and 25 participants in Peru.</jats:p><jats:p>It is not possible to make any conclusions regarding the effectiveness of preventive interventions. Four factors may be important for intervention design and implementation:</jats:p><jats:p>Having a range of programme components that appeal to youth such as arts and sports.</jats:p><jats:p>Active engagement of youths and gang leaders in forming and implementing the programme.</jats:p><jats:p>Ensuring continuity of social ties outside the gang which are fragile and may not be preserved after short‐term interventions.</jats:p><jats:p>Ongoing violence and gang involvement limits successful implementation so needs to be addressed.</jats:p></jats:sec><jats:sec><jats:title>Plain Language Summary</jats:title><jats:sec><jats:title>Background</jats:title><jats:p>Youth gang membership and the crime that it generates is a serious problem in low‐and middle‐income countries, involving many thousands of young people and resulting in billions of dollars of crime, loss of life, and social disruption. This review assessed the evidence on preventive interventions that focus on increasing social capacity to reduce gang membership or rehabilitate gang members outside of the criminal justice system.</jats:p></jats:sec><jats:sec><jats:title>Approach</jats:title><jats:p>We conducted an extensive search of the published and unpublished academic literature, as well as government and non‐government organization reports to identify studies assessing the effects of preventive youth gang interventions in low‐and middle‐income countries. We also included studies assessing the reasons for success or failure of such interventions and conducted a thematic synthesis of overarching themes identified across the studies.</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>We did not identify any studies assessing the effect of preventive gang interventions in LMICs using an experimental or quasi‐experimental design. Four studies evaluating the reasons for implementation success or failure were included. The limited number of studies included in the review suggests that the findings identified here should provide a direction for future research, rather than any substantive or generalizable claim to best practice. Specifically, the synthesis of reasons for implementation success or failure identified five factors that may be important for intervention design and implementation. Preventive gang interventions may be more likely to be successfully implemented when they include: <jats:list list-type="bullet"> <jats:list-item><jats:p>a range of program components that appeal to youth,</jats:p></jats:list-item> <jats:list-item><jats:p>active engagement of youth, where their agency is embraced and leadership is offered,</jats:p></jats:list-item> <jats:list-item><jats:p>programs that offer continuity of social ties outside of the gang, and</jats:p></jats:list-item> <jats:list-item><jats:p>a focus on demobilization and reconciliation.</jats:p></jats:list-item></jats:list></jats:p></jats:sec><jats:sec><jats:title>Implications</jats:title><jats:p>The lack of evidence prevents us from making any conclusions about which interventions are most effective in reducing youth involvement in gangs. To identify programs that work and those that do not researchers, practitioners and commissioners should begin to rigorously evaluate the effectiveness of preventive gang programs in the field.</jats:p></jats:sec></jats:sec><jats:sec><jats:title>Executive Summary</jats:title><jats:sec><jats:title>BACKGROUND</jats:title><jats:p>Youth gangs are frequently associated with high levels of crime and violence in low‐and middle‐income countries ‐‐ creating fear, reducing social cohesion, costing billions of dollars in harm and many thousands of lives diverted to criminality. However, youth gangs are also seen to fill a void, as a means of overcoming extreme disadvantage and marginalization. Preventive interventions focus on capacity building and social prevention, and are designed to work proactively to stop crime before it occurs, either by preventing youth from joining gangs or by reducing recidivism by rehabilitating gang members outside of the criminal justice system. By addressing the causes of youth gang membership, these interventions seek to reduce or prevent gang violence.</jats:p></jats:sec><jats:sec><jats:title>OBJECTIVES</jats:title><jats:p>There were two key objectives to this review. <jats:list> <jats:list-item><jats:p>To review the evidence on the effectiveness of interventions designed to prevent youth involvement in gangs and gang crime in low‐ and middle‐income countries. This objective has two parts: <jats:list> <jats:list-item><jats:p>to summarize the overall effectiveness of interventions, and</jats:p></jats:list-item> <jats:list-item><jats:p>to examine variability in effectiveness across different interventions and populations.</jats:p></jats:list-item></jats:list></jats:p></jats:list-item> <jats:list-item><jats:p>To identify the reasons why the implementation of preventive interventions to reduce youth involvement in gangs and gang crime may fail or succeed in low‐and middle‐income countries.</jats:p></jats:list-item></jats:list></jats:p></jats:sec><jats:sec><jats:title>SEARCH METHODS</jats:title><jats:p>The search for eligible studies was conducted in August and September 2013, as part of a broader project that systematically reviewed literature on conduct problems and crime in low‐ and middle‐income countries (LMIC). The search strategy included published and unpublished literature with no date constraints. The search was conducted across 17 academic databases, 8 individual journals, and 10 grey literature repositories. There were no language restrictions on the eligibility of documents, and the search was conducted in seven languages: English, French, Chinese, Arabic, Russian, Spanish and Portuguese. The geographic location of studies was limited to low‐ and middle‐income countries, defined as such by the World Bank at least 50 per cent of the time since 1987, when the recordings start.</jats:p></jats:sec><jats:sec><jats:title>SELECTION CRITERIA</jats:title><jats:p>Studies were eligible for the review of effectiveness if they: (1) reported on youth gangs; (2) included participants between 10 and 29 years old; (3) were located in a LMIC; (3) assessed a preventive intervention; and (4) used an eligible quantitative study design.</jats:p><jats:p>Studies were eligible for the review of reasons for implementation success or failure if they: (1) reported on youth gangs; (2) included participants between 10 and 29 years old; (3) were located in a LMIC; (4) assessed a preventive intervention; (5) evaluated the reasons for success or failure; (6) reported on the sampling strategy; (7) reported on data collection; and (8) reported on the type of analysis.</jats:p></jats:sec><jats:sec><jats:title>DATA COLLECTION AND ANALYSIS</jats:title><jats:p>A team of reviewers assessed each title and abstract for preliminary eligibility, which was confirmed during full‐text screening. No studies were eligible for the review of effectiveness. For the review of reasons for implementation success or failure, we recorded any evidence of barriers or facilitators of implementation that were identified by the study authors. None of the four studies that were eligible for the thematic synthesis were graded as having low study quality. The review contains a description of each intervention, a summary of the authors' findings and conclusions about barriers and facilitators of implementation success, and a thematic synthesis of overarching themes identified across the studies.</jats:p></jats:sec><jats:sec><jats:title>RESULTS</jats:title><jats:p>No studies were identified for the review of effectiveness.

Yet there are a large number of preventive gang programs currently in the field, and many studies that assert their effectiveness. We urge the research and practitioner communities to develop a program of rigorous evaluation, both quantitative and qualitative, in order to establish a benchmark for best practice and to systematically capture important learnings from a range of low‐ and middle‐income country contexts.</jats:p></jats:sec></jats:sec>
