The purpose of this project was to identify the outcomes associated with frequent, moderate, occasional, and nonparticipation in Alcoholics Anonymous by male alcohol dependents during the first month after treatment. Informants reported nonparticipants consumed far more alcohol during a 48 week followup than moderate or occasional participants. Moderate and occasional participants were rated as abstinent more often than nonparticipants. Nonparticipants were also reported jailed more often than participants. All other consumption and quality of life comparisons between the groups were nonsignificant. Occasional and moderate AA attendance appear to be associated with better outcomes than nonattendance, but frequent participation was not associated with additional improvement.
