Evidence suggests its dimensions may be useful for identifying problem drinkers in the general population at risk for developing alcohol dependence. To date, the model has not yet been investigated for this purpose. The present study investigated the Type A/Type B distinction in a community sample of problem drinkers as well as its predictive validity among problem drinkers with no history of alcohol dependence.
