Assessment of specific drug disorders in a sample of substance abuse patients: a comparison of the DIS and the SADS-L procedures.

Both the DIS and the SADS-L interviews offer researchers a procedure for assessing the presence of drug disorders categorized by drug class, as defined by psychiatric nomenclatures. In this study, the performance of the drug section of each interview was compared in a sample of hospitalized substance abuse patients. The classes of drug disorders assessed by both instruments and reported here include narcotics, amphetamines, sedatives and tranquilizers, cannabis, cocaine, and hallucinogens. On a group level, the DIS and SADS-L agreed fairly well for all drug classes except hallucinogens. A within-DIS comparison of DSM-III and Research Diagnostic Criteria (RDC) diagnoses followed the same pattern, except with higher agreement. Distinctions between drug abuse and dependence within a drug class were not as reliable as overall assessments. On only a small proportion of patients did the instruments agree completely for all drug classes within an individual. Implications of the findings for research on drug problems are discussed.
