A twelve-step program (or programme) is a fellowship which aims at the recovery of its members from the consequences of an addiction [1], a compulsion [2], or another harmful influence on their lives, with the help of the faith-based Twelve Steps. Also the specific program of recovery that is applied within such a fellowship, is called a twelve-step program. The fellowship, a bond of loosely organized, autonomous groups, functions on the basis of principles, formulated in the Twelve Traditions. Synonyms are anonymous program and A-program; the original twelve-step program is Alcoholics Anonymous [3] (A.A).
