The Effects of Sexual Offender Treatment: An International Meta-Analysis of High Quality Studies

Abstract | Word Stems | Keywords | Association | Citation | Similar Titles



Abstract:

Treatment of sexual offenders is a controversial topic. Therefore, sound evaluations are highly relevant for an evidence-based crime policy. In a comprehensive meta-analysis Lösel and Schmucker (2005) found overall positive effects, in particular for cognitive-behavioral and hormonal treatment. However, the results were rather heterogeneous and methodological differences accounted for the largest amount of outcome variance. As a consequence, we carried out an updated analysis which only contained studies with equivalent treatment and control groups (levels 3-5 on the Maryland Scale) and official measures of sexual recidivism as outcome criterion. Twenty-nine studies were eligible and all addressed psychosocial (mainly cognitive-behavioral) treatment programs. The mean effect size was smaller than in our previous meta-analysis but still significant (OR = 1.46). Randomized studies showed a slightly larger effect, however, the findings at all levels of methodological quality were not homogeneous. There were various moderator effects (i.e. sample size, individualization of program, and treatment context). Due to the small study numbers in subcategoies, most other moderators did not reveal significant differences. The discussion addresses consequences of these findings for practice, policy making and future research.
