Alcoholics Anonymous vs. Other Approaches: The Evidence Is Now In.

'An updated review shows it performs better than other common treatments and is less expensive.

For a long time, medical researchers were unsure whether Alcoholics Anonymous worked better than other approaches to treating people with alcohol use disorder. In 2006, a review of the evidence concluded we didn’t have enough evidence to judge.

That has changed.

An updated systematic review published Wednesday by the Cochrane Collaboration found that A.A. leads to increased rates and lengths of abstinence compared with other common treatments. On other measures, like drinks per day, it performs as well as approaches provided by individual therapists or doctors who don’t rely on A.A.’s peer connections.

What changed? In short, the latest review incorporates more and better evidence. The research is based on an analysis of 27 studies involving 10,565 participants.

The 2006 Cochran Collaboration review was based on just eight studies, and ended with a call for more research to assess the program’s efficacy. In the intervening years, researchers answered the call. The newer review also applied standards that weeded out some weaker studies that drove earlier findings.

In the last decade or so, researchers have published a number of very high-quality randomized trials and quasi-experiments. Of the 27 studies in the new review, 21 have randomized designs. Together, these flip the conclusion.

“These results demonstrate A.A.’s effectiveness in helping people not only initiate but sustain abstinence and remission over the long term,” said the review’s lead author, John F. Kelly, a professor of psychiatry at Harvard Medical School and director of the Recovery Research Institute at Massachusetts General Hospital. “The fact that A.A. is free and so widely available is also good news.

“It’s the closest thing in public health we have to a free lunch.”'>>>
