Researchers from Stanford University found that a 12-step oriented treatment program that included attending Alcoholics Anonymous meetings boosted two-year sobriety rates by 30% compared to cognitive-behavioral (CB) programs, the BBC reported.
Twelve-step oriented programs also cost 30% less than CB-based treatment for addiction, the researchers said.
Lead study author Keith Humphreys said the spiritual dimension of AA may explain why recovering alcoholics in such programs are better able to resist the temptation to return to drinking.
The study appears in the journal Alcoholism: Clinical and Experimental Research.
