Meta-analyses have suggested which young offenders are most likely to benefit from rehabilitation programs and what types of programs are most likely to be successful. These analyses suggest that the design of successful rehabilitation programs for young offenders involves the selection of suitable offenders, program integrity, an empowering organizational structure, and staff training. Meta-analysis studies are briefly described, factors characterizing intervention programs that reduce criminal behavior are noted, and client and treatment integrity issues in juvenile rehabilitation are discussed. The author concludes that rehabilitation is best delivered to high-risk groups, that is, offenders whose histories of offending strongly indicate they are highly likely to reoffend in the future. 29 references
