Subtypes of cocaine abusers: support for a type A-type B distinction.
The replicability and generalizability of a multidimensional alcoholism typological system was systematically assessed in 399 inpatient, outpatient, and non-treatment-seeking cocaine abusers. Two different cluster-analytic procedures supported the construct, concurrent, and predictive validity of the Type A-Type B distinction in cocaine abusers. Participants classified as Type B (33%) cocaine abusers exhibited higher rates of premorbid risk factors (family history, childhood behavior problems, personality, age of onset), more severe drug and alcohol abuse, more addiction-related psychosocial impairment, more antisocial behavior, and more comorbid psychiatric problems than Type A participants (67%). Multidimensional typological systems have had a major impact on the alcoholism field and may be equally important for the assessment, prevention, treatment, and theoretical understanding of other substance use disorders.
