Concordance among biological, interview, and self-report measures of drug use among African American and Hispanic adolescents referred for drug abuse treatment.
This study examined the concordance among urine assays, interview measures, and self-report measures of marijuana and cocaine use among 190 drug-abusing/dependent African American and Hispanic adolescents and their families at 3 assessment points of an 18-month randomized clinical trial study. Results demonstrated concordance among urine assays, a calendar method self-report measure (Timeline Follow Back [TLFB]), and a noncalendar method self-report measure (Adolescent Drug Abuse Diagnosis Scale). Diagnostic criteria of marijuana and cocaine abuse/dependence from a clinical structured interview (Diagnostic Interview Schedule for Children [DISC]) also converged, albeit weakly, with self-report measures. Adolescent and parent reports on DISC marijuana abuse/dependence diagnostic criteria were related; however, collateral findings for DISC cocaine abuse/dependence diagnostic criteria were equivocal. Differences in concordance among biological and self-report cocaine use measures were found for baseline TLFB assessments among African American participants. Implications for future use and refinement of adolescent drug use assessments are discussed.
