Alcoholics Anonymous and Other 12-Step Programmes for Alcohol Dependence

In this Cochrane systematic review, the Cochrane Collaborative found no studies demonstrating that Alcoholics Anonymous (AA) and other 12‐step approaches are effective at reducing alcohol use in people with alcohol dependence compared with other treatments. Researchers found problems with the studies in the review, including that many different interventions were often compared in the same study and too many hypotheses were tested at once to identify which factors determined treatment success.
