The work of Robert Meyers' CRAFT Community Reinforcement Approach and Family Training program ... differs significantly from Al-Anon in that it is a behavioral program which advocates that the CSO [Concerned Significant Other] can have a positive impact on the person using substances. The CRAFT program has been demonstrated in Meyers' research to be more effective than the Vernon Johnson type intervention or Al-Anon, with less negative side-effects and better outcomes, whether or not the person using substances enters treatment.
