Abstract

Intimate partner violence (IPV) is a serious health worldwide issue, and current treatment options are far from satisfactory. In this case series, we focused on male domestic offenders (MDO) as they are the most frequently responsible for IPV and targeted individuals displaying personality disorders (PDs) features and emotion dysregulation who were willing to accept court‐mandated treatment. The underlying idea was that addressing PD factors through a specific treatment would help form and sustain a working alliance, understand the psychological triggers of violent behaviours, and then develop strategies to reduce them. We evaluated an adaptation of metacognitive interpersonal therapy (MIT) for MDO. The primary qualitative outcome was a reduction in violent behaviour. The main quantitative outcome was the reduction in manifestations of PD features. Secondary outcomes were reductions in global symptoms and interpersonal problems. We also analysed changes in emotion dysregulation, impulsivity and metacognition.
