the number of drinking days and the total amount of standard drinks consumed in the preceding 90 days; drinks per drinking day was determined by dividing the total number of standard drinks by the number of drinking days; (6) Lifetime alcoholism severity was assessed with the 24-item MAST (Selzer et al. 1971); (7) Sociopathy was assessed with 7 items adapted from the antisocial personality disorder section of the SCID. Patients were rated on a 3-point scale (1 = absent or false, 2 = sub-threshold, 3 = threshold or true). We formed a continuous measure by taking the mean of the 7 items; and (8) An anxiety severity index was created by calculating the proportion of lifetime symptoms participants reported in the panic disorder, agoraphobia, social phobia, specific phobia, and obsessive-compulsive and generalized anxiety disorder sections of the SCID.
