What was done
This paper summarizes a 2020 Cochrane review evaluating Alcoholics Anonymous (AA) and clinically delivered 12-Step Facilitation (TSF) for alcohol use disorder (AUD). Searches across major databases from inception to August 2, 2019, identified 27 studies (21 RCTs/quasi-experiments, 5 nonrandomized studies, and 1 economic study; total n = 10,565) comparing AA/TSF against treatments such as cognitive behavioral therapy (CBT), motivational enhancement therapy (MET), alternative TSF formats, or no treatment. Random-effects meta-analyses pooled continuous outcomes using standardized mean differences and dichotomous outcomes using relative risk ratios, alongside cost-offset analyses.
What was found
The abstract reports qualitative directions of effect without reporting numerical effect sizes, confidence intervals, or financial savings. AA/TSF interventions performed at least as well as established active comparison treatments (such as CBT) across all drinking-related outcomes. For continuous abstinence and remission, AA/TSF outperformed other treatments. AA/TSF also demonstrated higher healthcare cost savings relative to other AUD treatments.
Why it matters
This summary provides rigorous review evidence that manualized 12-step facilitation interventions achieve equal or superior abstinence outcomes compared to standard behavioral therapies while lowering overall healthcare costs.
Limits
The abstract reports no numerical effect sizes, point estimates, confidence intervals, or cost figures. The pooled evidence includes nonrandomized and quasi-experimental designs alongside RCTs, with variations in intervention manualization and comparator intensities.
