AA adherence was below 20%. The main factors reported by patients as reasons for non-adherence to AA were relapse, lack of identification with the method, lack of need, and lack of credibility. The factors reported by patients as reasons for adherence were identification with the method and a way to avoid relapse. Although AA is considered an effective intervention for alcoholism, its adherence rate was excessively low. The identification of these nonadherence factors could help health professionals in referring certain alcoholic patients to therapeutic interventions other than AA.
The result of this study is unsurprising; essentially the same finding was made in a meta-analysis almost two years ago reported in the Cochran Report (Source) What's noteworthy here is that patients were asked their reasons. It would be useful if the various threads in the responses (objections to the 12-step approach on the one hand, denial on the other) were explored in more depth and an attempt made to untangle them.
