In this article, the authors present a brief review of the literature on the program of Alcoholics Anonymous with particular emphasis on data pertinent to how individuals "work the program." The authors describe the development of the Brown-Peterson Recovery Progress Inventory (B-PRPI) and present data on the demographic characteristics and "spiritual practices" of 93 successfully recovering members of twelve step groups. The authors present preliminary data supporting the validity and internal reliability of the B-PRPI and offer suggestions for its use in alcoholism, drug addiction, and codependency treatment programs and research settings.
