Background/objective: The outcome of a treatment program for a large sample of male perpetrators on probation for intimate partner violence (IPV) was evaluated with particular reference to the differential impact on family only (FO) versus generally violent (GV) perpetrators.
Method: Official rates of recidivism for three years post termination of treatment and probation were examined for 456 perpetrators after they were classified as FO and GV.
Results: Both treatment completion and type of perpetrator were predictive of IPV recidivism and time to recidivism. However, analyses conducted separately for the two groups indicated that participation in the intervention predicted both recidivism and time to recidivism for the GV but not FO perpetrators who participated in treatment. Specifically, GV men were responsive to treatment whereas FO men were not. Results were somewhat different depending on who was included in the no treatment comparison group.
Conclusions: Implications of these findings for one size fits all interventions in IPV are discussed with specific reference to the need to develop different interventions for GV and FO perpetrators
