Studies have documented associations between traumatic brain injury (TBI) and mental disorders. The relationship between psychopathic personality and TBI remains poorly understood, though both are associated with similar characteristics (e.g., low empathy, aggression, disturbances in social/moral behavior). Yet, it is not clear whether assessment of psychopathic features is influenced by presence versus absence of TBI, and which aspects of TBI may be associated with psychopathic traits. This study examined the psychopathy-TBI association in justice-involved women (N = 341) with structural equation modeling. We tested if measurement invariance of psychopathic traits was evident among those with versus without TBI and which TBI variables (number, severity, age at first TBI) predicted psychopathic features in conjunction with symptoms of psychopathology, IQ, and age. Results provided evidence of measurement invariance, and more women with TBI, compared to those without, met criteria for psychopathy. Younger age of TBI and TBI severity predicted interpersonal-affective psychopathic features. [ABSTRACT FROM AUTHOR]

To date, very few studies have explored the association between psychopathic traits and risky sexual behavior (RSB) among women. Here, we investigated this relationship in a sample of 137 incarcerated women. Psychopathic traits were assessed via the Hare Psychopathy Checklist–Revised (PCL-R) and lifetime RSB measures, including number of lifetime sexual partners, frequency of engaging in sexual intercourse while intoxicated, and frequency of forgoing protection (e.g., condom usage) during sexual intercourse, were assessed through self-report. PCL-R Facet 3 scores (assessing lifestyle psychopathic traits) were associated with an increased frequency of engaging in sexual intercourse while intoxicated. In addition, women scoring high on the PCL-R were more likely to engage in sexual intercourse while intoxicated compared with a previously collected sample of men scoring high on the PCL-R. The results obtained in the current study help improve our understanding of the association between psychopathic traits and RSB among women. [ABSTRACT FROM AUTHOR]

Individuals scoring high on psychopathic traits engage in various forms of risky behavior. However, the relationship between psychopathic traits and risky sexual behavior (RSB) is less understood, especially with participants recruited from incarcerated settings. Here, we investigated the relationship between RSB and psychopathic traits with n = 179 incarcerated adult male offenders who completed a self-report RSB questionnaire asking participants about their lifetime number of sexual partners and frequency of using a condom during sex. Psychopathic traits were assessed using the Hare Psychopathy Checklist – Revised (PCL-R). In independent-samples t -tests, participants scoring high on psychopathic traits (i.e., PCL-R total score ≥ 30) reported greater total number of sexual partners throughout their lifetime and were less likely to use a condom during sex compared to low-scorers (i.e., PCL-R total score ≤ 15). In multiple regression analyses, PCL-R total scores emerged as a significant predictor of reduced condom usage during sex, but covariate measures assessing general externalizing psychopathology, did not. Our results suggest that several public health concerns, including sexually transmitted infection transmittal and unwanted pregnancies, may arise due to individuals scoring higher on psychopathy engaging in risky sexual behavior to a greater extent compared to those scoring lower on psychopathy.
