This study used meta-analysis to examine the effectiveness of domestic violence interventions. Results from 50 reviewed studies revealed mean effect size d-values of .99 for adult interventions and .67 for child interventions. For control groups, adults had a mean effect size of .34, whereas children had a mean effect size of .01. This meta-analytic review suggests that interventions are effective, but that counseling interventions are more effective than advocacy interventions for both adults and children. In particular, CBT, Parent/Family, Empowerment, and Play therapy interventions seem to be equally highly effective for treating adults. For children, CBT seems to be the most effective, followed by Parent/Family, Empowerment, and Play therapy interventions. Further, interventions are effective at reducing maltreatment events, stress/distress, PTSD, and psychopathology; and increasing quality of life, social support, the parent-child relationship, and domestic violence skills in adults. Interventions are not effective at treating adult internalizing symptoms and self-concept. For children, interventions seem to be effective in the same areas as well as in decreasing behavior problems. Implications for current victim interventions are discussed as well as directions for future research.
