Psychopathy, psychological distress, and treatment history among perpetrators of intimate partner femicide, homicide, and other violent crimes in Buenos Aires, Argentina

Abstract

Intimate partner femicide—the killing of women based on their gender by their former or current partners—is a global long-standing manifestation of violence against women. Despite the enactment of femicide-specific laws in Latin America, femicide rates have remained relatively constant throughout the last decade. Often perpetrators are pathologized as suffering from mental illness, yet the data on their mental health status is still relatively unknown. Thus, more research is needed to understand the extent of poor mental health among these individuals. The purpose of this study was to compare levels of psychopathy, psychological distress, and treatment history among an all-male sample of intimate partner femicide perpetrators, male-male homicide perpetrators, and offenders convicted of other violent crimes in Buenos Aires, Argentina. This study utilized a cross-sectional survey based on data derived from a two-stage sampling strategy. The questionnaire included two standardized instruments for the measurement of psychopathy (revised Psychopathy checklist and the Levenson Self-Report Psychopathy scale) and one for general distress (Spanish version of 12-item General Health Questionnaire). The final sample included 205 prisoners including 68 intimate partner femicide perpetrators, 73 homicide perpetrators, and 64 individuals convicted of other violent crimes. There were no significant differences across these groups based on their socio-demographic characteristics. Participants did not differ in terms of their psychopathology; however, femicide perpetrators were statistically more likely to experience psychological distress. In addition, femicide perpetrators self-reported more prior episodes of mental and substance use treatments. The findings of increased psychological distress and prior mental health and substance use treatment among femicide perpetrators suggest that there may be missed opportunities for femicide prevention within the public health subspecialties of mental health and substance use disorders. This study suggests that femicide perpetrators likely require distinctive interventions, including self-assessments and harm mitigation tactics, to prevent their potential for femicide perpetration.
