The present study aimed to examine relationships between antisocial personality disorder (APD) symptoms in adulthood and retrospective reports of childhood maltreatment, parental bonding, and teasing, and while controlling for symptoms of depression and anxiety. Four hundred eleven non-clinical participants (99 males, 312 females), aged 18–65 years, recruited from an Australian university and the general public, completed the questionnaire package. Findings indicated significant associations between childhood maltreatment, parental bonding, teasing, depression, and anxiety, and levels of APD symptomatology. Hierarchical regression analysis revealed that physical abuse, physical neglect, teasing, and level of father care made the largest unique contributions to the prediction of APD scores after statistically controlling for comorbid depression and anxiety. Analysis of variance revealed higher levels of APD symptoms were reported by males and younger participants. This research contributes importantly to our understanding of factors influencing APD symptomatology, with clinical and early intervention implications.
