The Diagnostic Interview Schedule for Children (DISC) is a structured psychiatric diagnostic interview for children and adolescents aged 6 to 18, or their parents (Shaffer et al., 2000). It was developed primarily for epidemiological research but is also useful in clinical settings. The most recent version of the DISC (DISC-IV) is able to address more than 30 psychiatric diagnoses that occur in children and adolescents based on DSM-IV criteria. The DISC can be administered by trained lay interviewers. Most questions are worded so that they can be answered "yes", "no", and "somewhat" or "sometimes”. Questions reference the 2 weeks, 4 weeks, and year prior to the interview.
