A Dyadic Analysis of the Relationships Between Antisocial and Borderline Personality and Intimate Partner Violence Perpetration.

Cluster B personality disorders of antisocial personality disorder (ASPD) and borderline personality disorder (BPD) have been implicated in predicting intimate partner violence (IPV) perpetration. However, most studies include only male perpetrators and ignore the dyadic interactions among couples. The current study examines the interactive role of both partners' ASPD and BPD features to predict IPV perpetration with a dyadic perspective. Seventy-seven married heterosexual couples reporting recent partner violence participated in the study. Each partner completed the Revised Conflict Tactics Scales and the Millon Clinical Multiaxial Inventory-II. A considerable number of participants (53.25% of the men and 46.75% of the women for ASPD and 41.56% of the men and 42.86% of the women for BPD) scored higher than the diagnostic cutoff point. Actor-partner interdependence modeling examined the reciprocal influence of men's and women's personality disorder features on IPV perpetration in two separate actor-partner interdependence models. Results of the first model revealed that the IPV perpetration of both wives and husbands was predicted by their own ASPD scores. In the second model, men's IPV perpetration was predicted both by his own and his partner's BPD features, but this was not true of women's IPV perpetration. While ASPD was a consistent risk factor for IPV perpetration, there were gender differences in the influence of BPD on IPV perpetration. Women's BPD symptoms appear to put her at risk for victimization of IPV. Therefore, in couples experiencing IPV and having BPD symptoms, both partners may benefit from interventions to address emotional instability to prevent future IPV.
