Alcoholics Anonymous and other 12-step programs for alcohol use disorder

Area of Science:

• Addiction Medicine
• Public Health
• Behavioral Science

Background:

• Alcohol use disorder (AUD) presents a significant global health burden, encompassing disease, disability, mortality, and economic costs.
• Alcoholics Anonymous (AA), a long-standing recovery organization, offers accessible support for AUD, with recent research investigating its effectiveness.

Purpose of the Study:

• To evaluate the effectiveness of peer-led AA and professionally-delivered Twelve-Step Facilitation (TSF) interventions for AUD.
• Key outcomes assessed include abstinence rates, reduced drinking intensity, fewer alcohol-related consequences, and healthcare cost offsets.

Main Methods:

• A systematic review and meta-analysis of randomized controlled trials (RCTs), quasi-RCTs, and non-randomized studies.
• Searches included multiple databases (e.g., Cochrane, PubMed, Embase) and ongoing trial registries, with no language restrictions.
• Interventions were compared to other treatments (e.g., CBT, MET) or no treatment, focusing on manualized versus non-manualized AA/TSF.

Main Results:

• High-certainty evidence shows manualized AA/TSF improves continuous abstinence rates at 12, 24, and 36 months compared to other clinical interventions.
• AA/TSF demonstrates comparable effectiveness to other treatments for reducing drinking intensity and alcohol-related consequences.
• Studies indicate AA/TSF interventions likely generate substantial healthcare cost savings.

Conclusions:

• Manualized AA/TSF interventions are highly effective for increasing abstinence in AUD, potentially surpassing other treatments.
• Both manualized and non-manualized AA/TSF appear effective for various alcohol-related outcomes.
• AA/TSF interventions are associated with significant healthcare cost reductions for individuals with AUD.
