On meeting inclusion and exclusion criteria, participants were given an intake diagnostic evaluation, which consisted of (1) demographic history; (2) alcohol, drug, and psychotic screen sections of the Structured Clinical Interview for DSM-III-R (SCID; Spitzer and Williams, 1985); (3) estimates of alcohol consumption via the Form 90 (Miller and Del Boca, 1994); (4) legal, psychiatric, and family history sections of the Addiction Severity Index (McLellan et al., 1992); and (5) psychological evaluation of mood, sociopathy, and social support. After providing informed consent and completing intake assessments, participants were then randomized to one of three treatments (CBT, MET, and TSF). Follow-up assessments were conducted immediately after treatment and 6, 9, 12, and 15 months after the first therapy session. A comprehensive list of all follow-up assessments can be found in previous Project MATCH publications (Project MATCH Research Group, 1993, 1997). For the current study, measures were used from the initial post-treatment assessment and the 6- and 12-month assessments following treatment. Measures relevant to the current study are described below.
