first six weeks of treatment and average DDD of 2.5 (SD=5.4) during the last week of treatment. Class 5 (6.8% of the sample), “consistent low drinking”, reported low risk drinking throughout treatment with average DDD of 2.85 (SD=1.60) and average PDD of 49.4% (SD=26.2%). Class 6 (10.5% of the sample), “abstinence-to-low risk drinking”, reported a high probability of abstinence initially and an increasing probability of low-risk drinking with average DDD of 3.52 (SD=2.29) and average PDD of 10.7% (SD=9.2%). Class 7 (39.8% of the sample), “abstainers”, reported a high probability of abstinence throughout treatment. As described previously[6], individuals in the low risk drinking classes (Classes 5 and 6; 17.3% of the total sample) were not significantly different (ps>0.05) from abstainers (Class 7), with respect to post-treatment functioning on measures of drinking consequences up to 12-months post-treatment and mental health up to 9-months post-treatment.
