title: Gender differences in autonomic indicators of antisocial personality disorder features.
abstract: We investigated the autonomic indicators of antisocial personality disorder (APD) features in a mixed gender student sample. One hundred college students (50 men, 50 women) were administered an interview of APD and self-report measures of aggression and psychopathy. Participants completed a passive coping task and viewed emotionally valenced slideshows while their electrodermal activity (EDA), pre-ejection period (PEP), and respiratory sinus arrhythmia (RSA) were measured. Associations between APD features and autonomic reactivity were examined, controlling for aggression and psychopathy. APD features were associated with EDA hyporeactivity in men, but not women, during passive coping. While viewing threatening slides, APD features were associated with RSA hyperreactivity in women and with PEP hyperreactivity in men. APD features were associated with RSA hyperreactivity in women, but not men, while viewing slides of others in distress. These findings suggest that APD features are characterized by parasympathetic nervous system dysfunction in women but sympathetic nervous system dysfunction in men.
