Problem drinker drivers: client and service involvement correlates of treatment outcome

Data collected on drinking drivers referred to the Philadelphia Alcohol Highway Safety Program are reported. The data suggest those referred to be older, male, and to demonstrate an unusually high degree of familial and social disruption. Impairment of functioning at the time of arrest, prior arrest histories for similar offenses, and other indicators similarly describe a population of serious problem drinkers. Data are also presented regarding correlates of successful treatment outcome. The data presented here underscore the need for further attention to appropriate interventions for this population.
