Abstract

Summary: Methodological issues such as social desirability bias, subjective outcome measures, therapist enthusiasm and fidelity to the intervention remain a major problem in assessing the effectiveness of psychosocial treatments for substance misuse. Alcoholics Anonymous and other 12-step programmes are still widely used, although it is difficult to formally assess their effectiveness. Motivational interviewing is perhaps the most commonly used professional psychosocial treatment for substance misuse, but brief interventions based on this technique report a disappointing effect size (∼0.2). Contingency management is perhaps the most effective reported modality, although it remains politically controversial. Cognitive—behavioural therapy and community reinforcement have been widely studied, but the results are often disappointing (effect sizes seldom exceed 0.5, despite very large trials). Residential rehabilitation remains an established treatment, but patient selection prevents formal cost-effectiveness studies.
