The DISC-C has undergone several adaptations and now features a DSM-IV version. There are separate forms of the interview for the parent and the child. As part of a larger study focusing on several diagnoses, Fisher and colleagues (1993) found the DISC-C to be highly sensitive in correctly identifying youth who had received a hospital diagnosis of any substance use disorder (n=8). Both interview forms had a sensitivity of 75%. For the one parent-child disagreement case, the parent indicated that they did not know any details about their child's substance use.
