THE DIAGNOSTIC INTERVIEW SCHEDULE FOR CHILDREN REVISED VERSION (DISC-R) .3. CONCURRENT CRITERION VALIDITY

Objective: To examine the concurrent criterion validity of the Revised Diagnostic Interview Schedule for Children (DISC-R), a structured lay -administered instrument designed for use in community studies, under conditions designed to provide strict controls for information and met hod variance. Method: The DISC-R was compared with a semistructured cl inical interview that covered a similar information base as the DISC-R , used standardized ratings to record symptom information, and, simila r to the DISC-R, was scored by DSM-III-R-based computerized diagnostic algorithms. Subjects were 74 child and adolescent clinic attendees an d their adult custodians. Results: Overall, moderate levels of agreeme nt were found between DISC-R and clinician-generated diagnoses; these findings were tempered, however, by the fact that the validation inter view was less reliable than the DISC-R. Conclusions: Although these fi ndings provide preliminary support for the use of die DISC-R, they cas t some doubt on the adequacy of clinician-generated diagnoses as valid ation criteria and suggest that alternate approaches to the assessment of validation should be pursued.
