title: Predictors of relapse to heavy drinking in alcohol dependent subjects following alcohol detoxification-the role of quality of life measures, ethnicity, social class, cigarette and drug use.
abstract: Sixty DSM-IV alcohol dependent adults (39 males, 21 females) admitted to a voluntary sector alcohol detoxification unit in South London were studied. Socio-demographic data and information on level of alcohol dependence, quality of life, family history, cigarette smoking and the use of prescription/illicit drugs were collected. The subjects were followed-up at 12 weeks and subdivided into two groups, relapse and non-relapse. A relapse was defined as drinking 21 units or more per week for males and 14 units or more per week for females. Data were analysed for baseline and 12-week follow-up comparisons. At 12 weeks, 58 (97%) subjects (38 males, 20 females) were successfully followed-up and 36/58 (62%) had relapsed. After controlling for a Type I error there were significant differences between the relapse and non-relapse subgroups at 12-week followup on the following outcome measures; depression, life situation, withdrawal symptoms, energy, emotional reactions and social isolation. There were no significant differences at baseline between the relapse and nonrelapse subgroups for most of the socio-demographic variables, but Irish nationality and membership of lower social classes (IV and V) were associated with relapse. Major predictors of relapse at baseline after a forward stepwise logistic regression were (in order of increasing statistical significance) Irish nationality, lower social class, greater number of cigarettes smoked and disturbed sleep. The findings are discussed with reference to their consistency with existing research and potential clinical implications.
