Intimate partner violence perpetration and psychopathy : A comprehensive review

Intimate partner violence (IPV) is the physical, sexual, and psychological abuse of an intimate partner and is a widespread, international public health crisis. An important proximate risk factor for IPV perpetration is the presence of psychopathic traits but there has not been a systematic review of the research linking psychopathic traits to IPV perpetration. We identified 43 studies using 13,476 participants (9,024 men and 4,452 women) across 10 countries that met our search criteria that led to the following conclusions. First, psychopathy was associated with IPV perpetration with medium effect sizes, even after accounting for various distal and proximate risk factors. Second, the different dimensions of psychopathy did not consistently differ in their prediction of IPV perpetration. Third, within individuals with a history of IPV perpetration, psychopathy did not relate to the frequency or severity of partner violence. Fourth, a few studies have tested the associations among child abuse, psychopathy, and IPV, with one study reporting that the combination of child abuse and psychopathic traits led to especially high risk for IPV perpetration. Lastly, we conclude by making recommendations for how future research and interventions should consider psychopathy to reduce the societal burden of IPV.
