Alcoholism Diagnoses for Convicted Drinking Drivers Referred for Alcoholism Evaluation

The types and extent of alcohol-related problems were determined for a sample of 461 convicted drinking drivers who were referred to an alcoholism treatment facility for evaluation and possible treatment. Using responses to questionnaire and structured interview questions on alcohol-related problems, DSM III diagnoses are constructed; approximately three-quarters of the sample are diagnosed with sufficient severity for a DSM III diagnosis of abuse or dependence. Self-reported consumption levels and drinking/driving incidents increase as the level of the alcohol problem increases; persons in the Alcohol Abuse category are heavier consumers and drive more frequently after drinking than are persons who are not diagnosed by the DSM III as having an alcohol problem. Persons in the Alcohol Dependence category are heavier consumers than either the Alcohol Abuse or Undiagnosed Problem categories and report more drinking/driving incidents. The DSM III provides useful subcategories of convicted drinking drivers referred for alcoholism evaluation and distinguishes groups differing in quality, frequency, and self-reported DWI measures, independent of basic demographics. These analyses suggest that drinking/driving countermeasures should include intervention efforts to address alcohol-related problems. Serious alcohol problems exist among some drinking drivers, and drinking/driving incidents are more frequent among these individuals.
