12-Step involvement among a U.S. national sample of Oxford House residents

A longitudinal analysis was conducted among a U.S. national sample of persons affiliated with Alcoholics Anonymous and Narcotics Anonymous living in self-run recovery homes (Oxford Houses). Categorical involvement in a set of 12-step activities (i.e., having a sponsor, reading 12-step literature, doing service work, and calling other members for help) and averaged summary scores of involvement were examined in relation to abstinence and self-efficacy for abstinence. Participants who were categorically involved in all 12-step activities reported significantly higher levels of abstinence and self-efficacy for abstinence at 1 year compared with those who were less involved, whereas averaged summary scores of involvement were not a significant predictor of abstinence. Participants' number of days in Oxford Houses, but not rates of 12-step meeting attendance, was significantly related to increased abstinence. Findings suggest that categorical involvement in a number of 12-step activities equip persons with substance use disorders with resources for ongoing recovery.
