Background and Aims Recovery from alcohol use disorder (AUD) is often narrowly defined by abstinence from alcohol and improvements in functioning (e.g. mental health, social functioning, employment). This study used latent profile analysis to examine variability in recovery outcomes, defined by alcohol use, alcohol-related problems and psychosocial functioning at 3 years following treatment. Secondary analysis investigated pre-treatment, post-treatment and 1- and 3-year post-treatment covariate predictors of the latent profiles. Design Secondary analysis of data from a randomized clinical trial. Setting United States. Participants We used data from the out-patient arm of Project MATCH (n = 806; 29.7% female, 22.2% non-white). Measurements Recovery was defined by latent profile analyses including measures of psychosocial functioning and life satisfaction (Psychosocial Functioning Inventory), unemployment and mental health (Addiction Severity Index), alcohol and other drug use (Form 90) and alcohol-related consequences (Drinker Inventory of Consequences) 3 years following treatment. Mixture modeling was used to examine correlates of profiles. Findings We identified four profiles at 3 years following treatment: (1) poor functioning frequent heavy drinkers, (2) poor functioning infrequent heavy drinkers, (3) high functioning occasional heavy drinkers and (4) high-functioning infrequent non-heavy drinkers. There were relatively few differences on indicators of functioning and treatment-related variables between the high functioning infrequent non-heavy drinkers and the high-functioning occasional heavy drinkers, other than high-functioning occasional heavy drinkers having lower alcohol dependence severity [odds ratio (OR) = 0.94, 95% confidence interval (CI) = 0.90, 0.98], fewer post-treatment coping skills (OR = 0.54, 95% CI = 0.32, 0.90) and lower 3-year post-treatment abstinence self-efficacy (OR = 0.37, 95% CI = 0.28, 0.49) and Alcoholics Anonymous (AA) involvement (OR = 0.87, 95% CI = 0.85, 0.99). The two high-functioning profiles showed the greatest improvements in functioning from baseline through the 3-year follow-up, whereas the low-functioning profiles showed the least amount of improvement. High-functioning occasional heavy drinkers had higher purpose in life than the poor-functioning profiles. Conclusions Some individuals who engage in heavy drinking following treatment for alcohol use disorder may function as well as those who are mostly abstinent with respect to psychosocial functioning, employment, life satisfaction and mental health.
