In general, the five studies into the effectiveness of a variety of residential treatment approaches indicate that such treatments, particularly if appropriately matched to the juvenile offender, can have positive in-program effects. However, results concerning the maintenance and generalization of positive outcomes have been disappointing, and recidivism rates are high. A meta-analysis conducted by Garrett (1985) examined the experimental rigor, comparative effectiveness of treatments, effects on different outcome measures, and effect size by individual treatments reported in 111 studies. Results show an overall positive effect of treatment on outcomes, including recidivism. In addition, results indicate a differential effectiveness among treatment approaches and suggest that contingency management, cognitive behavioral therapy, family therapy, and certain life-skill interventions warrant further evaluation. 61 references.
