A Systematic Review of the Quality of Perpetrator Programs’ Outcome Studies: Toward A New Model of Outcome Measurement

This systematic review assessed whether studies on the outcomes of perpetrator programs comply with the model recommendations for outcome evaluation. Three databases (PsycINFO, Medline, and Scopus) were used to identify perpetrator program outcome studies from 1988 to 2021. The inclusion criteria were as follows: empirical studies with no time restriction; published in English or Spanish; evaluated interventions aimed at male perpetrators of any type of abuse toward women; evaluated the effectiveness of the intervention in a follow-up post-intervention; and provided an indicator of recidivism. The search and selection process resulted in 46 original studies. The results showed that studies did not include a thorough description of the study sample. Many approaches to psychological intervention are used, with cognitive behavioral therapy being the most widely used. Most studies did not describe the program content. Dropout rates varied greatly from one study to another (from 0% to 64%) and only eight studies provided dropout rates specified by each type of perpetrator. The follow-up period ranged from 3 months to 9 years. The recidivism rates (ranging from 5% to 72.5%), and their assessments were also very different. Only 12 of the 46 studies (26.1%) used more than one source to obtain recidivism rates. In terms of outcomes, few studies considered (ex-) partner accounts. Some studies had other measures of outcome, whereas a few included a pretest–posttest. In summary, these studies do not follow the recommendations of the model.
