An empirical assessment of post-treatment alcohol consumption.

Substance abuse treatment programs have long contended that any post-treatment alcohol use is indicative of relapse. Recent studies, however, suggest more inclusive definitions. Zweben and Cisler (1996, 1999) consider both the drinking quantity and negative drinking consequences. Their proposed cutoffs integrate the 1995 NIAAA guidelines for sensible and high risk drinking levels with the objective assessment of drinking-related consequences into the definition of relapse. Our study applied this model to a group of detoxified alcoholics in a post-treatment followup project. We asked if: (1) Zweben and Cisler's drinking categories could be found in our sample; (2) whether subgroups defined by post-treatment drinking patterns differed with respect to their pre-treatment alcohol consumption levels, years of alcoholic drinking and drinking related problems; and (3) whether post-treatment drinking patterns were associated with differential psychosocial functioning at followup. Thirteen percent of the total sample (N=61) was found to meet Zweben and Cisler's moderate drinking category; 34% were abstinent, 27% heavy drinkers and 13 participants (26%) were unclassifiable. At treatment completion (T1), those who became moderate drinkers reported higher levels of self-confidence, but were otherwise similar to both abstainers and heavy drinkers. At followup (T2), approximately 1 year after initial testing (T1), groups differed on measures of emotional discharge, avoidance and logical coping skills and information seeking, suggesting a possible association between post-treatment drinking patterns and psychosocial functioning.
