Does Alcoholics Anonymous work? The results from a meta-analysis of controlled experiments

Area of Science:

• Addiction research
• Psychology
• Public health

Background:

• Alcoholics Anonymous (AA) is a widely utilized addiction recovery program.
• The effectiveness of AA remains a subject of ongoing scientific inquiry.
• Methodological rigor in studies assessing AA outcomes is crucial for reliable conclusions.

Purpose of the Study:

• To critically review the outcomes of 21 controlled studies on Alcoholics Anonymous (AA).
• To evaluate the methodological quality of studies assessing AA's effectiveness.
• To identify specific AA components that may contribute to recovery.

Main Methods:

• Systematic review of 21 controlled studies evaluating Alcoholics Anonymous (AA).
• Emphasis on assessing the methodological quality, including selection biases.
• Comparison of outcomes between AA participation, alternative treatments, and no treatment.

Main Results:

• Quasi-experimental studies were compromised by significant selection biases.
• Randomized studies showed worse outcomes for AA compared to nonrandomized ones, but were biased by coerced participation.
• Conventional AA meetings were associated with worse outcomes than no treatment or alternative therapies.
• Residential AA-modeled treatments showed comparable outcomes to alternatives.
• Certain AA components, such as peer therapists and the Twelve-Step process, showed potential support.

Conclusions:

• Methodological limitations, particularly selection bias, challenge the interpretation of many AA studies.
• Conventional AA attendance may be less effective than alternative interventions.
• Specific elements within the AA framework, like peer support and structured recovery processes, warrant further investigation for their therapeutic value.
