Each participant completed a 1.5 to 2.5 hour face-to-face structured interview. The diagnostic sections of the interview were based on the Semi-Structured Assessment of the Genetics of Alcoholism - Australia (SSAGA-OZ) and allowed for lifetime DSM-IV and/or DSM-III-R diagnoses to be made for heroin abuse and dependence, alcohol, cannabis, sedative, stimulants, and cocaine abuse and dependence, nicotine dependence, post-traumatic stress disorder (PTSD), major depressive episode, panic disorder and antisocial personality disorder (ASPD) (Bucholz, et al., 1994; Hesselbrock, Easton, Bucholz, Schuckit, & Hesselbrock, 1999). A screener for borderline personality disorder (BPD) was adapted from the International Personality Disorder Examination (IPDE) (Loranger, et al., 1994). Sections of the Christchurch Health and Development Study interview were modified to assess for childhood trauma and adult victimization history (Fergusson, Horwood, Shannon, & Lawton, 1989). Sexual abuse included 10 items asking about non-contact, contact and penetrative sexual abuse, as well as items assessing onset and recency, and relationship of perpetrator to the participant. Physical abuse included 13 items asking about physical assault from a caregiver or injury arising from a caregiver’s actions towards the participant. Conflict
