What is the relationship of abstinence to controlled-drinking outcomes over time?
Edwards et al. (1983) reported that controlled drinking is more unstable than abstinence for alcoholics over time, but recent studies have found that controlled drinking increases over longer follow-up periods. Finney and Moos (1991) reported a 17 percent “social or moderate drinking” rate at 6 years and a 24 percent rate at 10 years. In studies by McCabe (1986) and Nordström and Berglund (1987), CD outcomes exceeded abstinence during follow-up of patients 15 and more years after treatment (see Table 1). Hyman (1976) earlier found a similar emergence of controlled drinking over 15 years.
