Why Does Alcoholics Anonymous Work?

The video explores the effectiveness of Alcoholics Anonymous (AA) in promoting abstinence from alcohol. It discusses the challenges of distinguishing between treatment effects and selection effects in studies, particularly in randomized controlled trials (RCTs). The video explains how crossover in RCTs can obscure genuine treatment effects and introduces the concept of intention to treat analysis. It highlights a study that corrects for crossover by focusing on marginal patients, providing insights into AA's true treatment effect. The video concludes by affirming AA's benefits and encouraging more participation.

Who are considered 'marginal patients' in the context of treatment studies?

• Patients who are not part of the study

• Patients who attend all treatment sessions

What is the main conclusion about Alcoholics Anonymous from the study?

• It is more effective than any other treatment

• It is only effective for highly motivated individuals

• It helps alcoholics apart from attracting motivated individuals

What is the next step suggested after establishing the benefits of AA?

• To limit AA to specific regions

• To reduce the number of AA meetings
