title: Multidimensional subtypes and treatment outcome in first-time DWI offenders.
abstract: The concurrent and predictive validity of Type A and B alcoholism subtypes was evaluated in 246 first-time driving-while-intoxicated (DWI) offenders. K-means analysis indicated that a two-cluster solution was optimal with Type Bs (28%) exhibiting greater premorbid risk factors, alcohol and psychosocial severity, drinking consequences, psychopathology, higher stage of change, and less coping confidence in comparison to less severe Type As (72%). After baseline assessment, participants were randomly assigned to one of three 10-week group treatments (DWI Education, Coping Skills, Interactional), and reassessed at termination, and at 6-month and 1-year follow-ups. Type B was associated with more severe symptoms after treatment, but there was no evidence for patient-treatment matching effects. Although Type A/B may be an important theoretical model for guiding alcoholism research, it usefulness and efficiency for treatment matching, planning, or placement purposes is questioned.
