(NicD, AlcD, DrgD) was assessed using the expanded substance abuse module (Robins et al., 1988) as they pertained to lifetime (intake and second visits) and since-last-visit (third and fourth visits) experience. Clinical reports were independently reviewed by at least two individuals with advanced clinical training (Cohen’s κ’s > 0.7) (Iacono et al., 1999) who whenever they did not score a symptom identically, reviewed the symptom together to achieve consensus. The comparison group for the present study consisted of those who met criteria for none of the above disorders at any of the four assessments. In addition, they did not meet criteria for DSM-III-R substance abuse.
