Characteristics of Former Heavy Drinkers: Results from a Natural History of Drinking General Population Survey

Abstract

This study explored the factors associated with reduction from heavy drinking among three groups: current abstinent, moderate, and reduced drinkers. A random-digit-dialing telephone survey was conducted of 3,006 respondents in Ontario, Canada. Of these, 470 respondents (46% female) met criteria as former heavy drinkers (99 abstinent; 237 moderate; 134 reduced but not moderate drinkers). Quantitative and qualitative questions were used to explore current and past drinking, use of treatment, and reasons for change. Qualitative items were tape-recorded and transcribed. Respondents in the abstinent group had more severe problems prior to resolution as compared with those in the moderate group. Reduced drinkers displayed a prior alcohol severity at a level between these two other groups. The most common reasons for change in all groups were new responsibilities, maturation, and health concerns. This study serves as a useful adjunct to other natural-history research, exploring the reasons for change in a representative sample of former heavy drinkers.
