Subtypes for classifying adolescents with marijuana use disorders: construct validity and clinical implications.

AIMS: To evaluate the construct and predictive validity of six different subtyping classifications selected on the basis of their empirical support in the literature on adolescent substance abuse. METHODS: Typological data were collected from a heterogeneous sample of 600 adolescents presenting for marijuana treatment. The classification schemes were gender, onset age, family history, externalizing disorders, internalizing disorders and temperament. Subgroups were compared in terms of substance use frequency, substance abuse problems, social support for substance use, family conflict, school problems and negative peer associations. RESULTS: Each of the categorical classification schemes differentiated subtypes significantly on some or all of the construct validation measures after controlling for demographic factors, thereby indicating that each has valuable explanatory power from a theoretical perspective. Externalizing disorders, onset age, difficult temperament and internalizing disorders continued to add unique variance to discrimination after the effects of the other subtypes had been removed. At 12-month follow-up there were no differences between subtypes on substance use frequency, but adolescents with higher levels of externalizing disorders and internalizing disorders continued to experience more substance use problems. CONCLUSION: Categorical subtypes may have particular relevance to the development of treatment interventions as well as prevention measures.

Prevalence of cocaine and marijuana use among pregnant women in a military health care setting.

BACKGROUND: Illicit drug use is common in the United States. The degree of substance abuse among pregnant women, its prevention, and treatment are currently matters of great concern. METHODS: We conducted a blinded cross-sectional study on the prevalence of cocaine and marijuana metabolites in the urines of an obstetric population served by a military community hospital. Ninety percent of patients screened were nonactive-duty family members. RESULTS: An overall illicit drug use prevalence of 1.6 percent was found. This contrasts to prevalences of 10 to 15 percent reported in civilian obstetric populations. CONCLUSIONS: Job site drug screening of the active-duty soldier may be the reason for differences between the military and nonmilitary populations.
