Evaluations of correctional treatment programs in Germany: A review and meta-analysis

This study presents a review and meta-analyses of research on the recidivis m-reducing impact of correctionally based treatment programs in Germany. Th e data are part of the Correctional Drug Abuse Treatment Effectiveness (CDA TE) project meta-analytic database (covering 1968-1996) of evaluation resea rch studies of correctional interventions. Overall, the five studies of edu cational programs show no practical impact of these programs in reducing re cidivism. Four studies of programs to counsel driving-under-the-influence ( DUI) offenders fall in an intermediate area (not statistically significant, but promising enough to warrant further research). The eight studies of So cial Therapy programs did show, on the average, a statistically significant practical impact in reducing recidivism.
