substance use disorders are assessed using a modified version of the expanded Substance Abuse Module (SAM) developed by Robins et al. (1987) as a supplement to the WHO's Composite International Diagnostic Interview (Robins et al., 1988). We have added questions to the SAM covering quantity and frequency of use, the Fagerstrom Test for nicotine dependence (Heatherton et al., 1991), maximum drinks in 24 hours, patterns of binge drinking, and an expanded list of prescription drugs that may be abused. Finally, we comprehensively assess mood and anxiety disorders, using the Structured Clinical Interview for DSM-III-R and IV (Spitzer et al., 1992) to assess MDD, mania/hypomania, specific/social anxiety, panic disorder, agoraphobia, and generalized anxiety disorder.
