Description

Among the intervention models for domestic violence perpetrators, the two best known are the “Duluth Model” and “Cognitive Behavioral Therapy” (CBT).
Originating from the Domestic Abuse Intervention Project implemented in Duluth (Minnesota, USA) in 1981, this intervention model is based on the understanding that the main cause of domestic violence is the prevalence of a patriarchal social and cultural ideology that has historically allowed men to control women, either through the exercise of power or through direct violence. Based on this theoretical formulation, the Duluth Model advocates a feminist psycho-pedagogical approach that includes group exercises aimed at modifying the abusive and threatening behavior of men involved in cases of domestic violence.
On the other hand, Cognitive Behavioral Therapy interventions applied to perpetrators of domestic violence were developed by psychologists as a way to treat violent behavior. These interventions interpret violence as a behavior that is learned by individuals and, consequently, assume that nonviolence can also be learned by perpetrators involved in domestic violence cases. This model focuses on identifying the thought processes and beliefs that contribute to violence, and aims to promote transformations in the violent behavior of perpetrators. In therapy sessions (which may be 1:1 or in small groups), men who have perpetrated such physical abuse are encouraged to reflect on their conception of violence and to change their thinking, as well as to examine the circumstances surrounding their practice and interrupt violent attitudes and behaviors in domestic settings, especially against women.

Evidence

The efficacy of interventions to interrupt intimate partner violence has been a controversial topic. Although there is evidence that Cognitive Behavioral Therapy interventions are not effective and that the Duluth Model was only able to produce small to medium effects on the victimization of women who suffer domestic violence [1][2], more recently, a meta-analysis reported that both types of intervention produce statistically significant reductions in violence against women, with better results for Cognitive Behavioral Therapy [3].
According to the findings of this latest systematic review, the effect of these interventions was nil when considering cases in which recidivism was measured through partner reports, whereas it was positive and significant in terms of reducing recidivism when measured through official records. In addition, short interventions (less than 16 sessions/4 months) were not effective to reduce recidivism (measured in official records) and may have negative effects (increased recidivism), whereas longer interventions (more than 16 weeks/4 months of sessions) were effective to reduce recidivism rates [3].
