Lifetime AAD diagnosis was made using DSM-IV criteria based on a structured diagnostic interview assessment, adapted from the Structured Clinical Interview for DSM Disorders (SCID; Spitzer & Williams, 1985) and administered by clinically trained interviewers. Test–retest reliability estimates for lifetime AAD were obtained among randomly selected participants re-interviewed 2–8 weeks after their original interviews [k=0.74, 95% confidence interval (CI)=0.66–0.82, n=192]. Approximately 35% of the sample met the criteria for lifetime AAD, consistent with other surveys of general population samples of males in the USA (Hasin et al. 2007).
