Personality characteristics in specialist and generalist intimate partner violence perpetrators.

Intimate partner violence (IPV) is one of the most common types of violence against women. Although personality disorders have been associated with IPV, perpetration research regarding personality according to the classification specialist/generalist IPV perpetrators is scarce. The general aim of this study was to describe personality in a large sample of IPV Spanish male perpetrators considering their classification (specialist vs. generalist). Participants were 1093 men convicted of IPV crimes whose ages ranged from 18 to 76 years old (M = 40.15; SD = 10.32). Of them, 554 men were classified as specialist perpetrators and 539 men were classified as generalist perpetrators. Participants completed questionnaires regarding sociodemographic and violence aspects as well as the Spanish version of the Millon Clinical Multiaxial Inventory III. Generalist perpetrators showed higher means in nearly all the personality disorders scales compared to specialist perpetrators. Prevalence rates in the majority of personality disorders were lower than 5%. Higher scores on the avoidant, histrionic, and self-defeating scales and lower scores on the aggressive, borderline, and drug dependence scales were related to being a specialist perpetrator. This study contributes to a better understanding of personality among generalist and specialist perpetrators.
