Twelve-Step (TS) recovery utilizes spirituality to promote sobriety, yet there are no proven programs designed to facilitate spiritual involvement. We developed a seven-week behavioral spirituality intervention titled "Knowing Your Higher Power" for implementation along with usual TS care. Twenty-six participants from a recovery center enrolled. We assessed behavior at baseline, 7-week, and 12-week follow-up. The sample showed significant increase in spiritual involvement and beliefs over the 12-week measurement period and a significantly greater spirituality score in those maintaining total sobriety compared to those that relapsed. These findings encourage a controlled trial to determine if this work has efficacy for practitioners in substance abuse treatment.
