A sample of 44 women and 50 men attending an alcohol treatment facility were assessed on a range of demographic, social and psychological measures in order to determine whether women and men relapse for different reasons. Clients were monitored for a 3 month period after the initial intake interview whereupon follow-up interviews were conducted. The data were analysed by the use of survival analysis techniques. The results indicated that there were different predictors of relapse across the three levels of post treatment alcohol use investigated. Gender differences were present at two of these levels. The implications of these differences are discussed.
