4 Is a fully structured diagnostic instrument that assesses thirty-four common psychiatric diagnoses of children and adolescents. The DISC is designed for Interviewer administration - either by lay interviewers (people with no formal clinical training) or by clinicians or by self-completion. The DISC-IV has been designed to obtain information about Diagnostic and Statistical Manual - IV (DSM IV) diagnoses, essentially by ascertaining the presence or absence of symptoms. The instrument uses the diagnostic criteria as specified in DSM-IV (with DSM-III-R, and ICD-10 in development). It does not elicit contextual information except to determine bereavement reactions, and specific rule-outs that would cast doubt on the diagnoses ( failure to speak in Selective Mutism when unfamiliar with English).

5 In addition, the DISC is DSM-IV loyal and all symptom criteria must be met to meet the diagnosis. The DISC cannot be used to establish a diagnosis for conditions that require the interpretation of specialized test results or to substitute for information derived from astute clinical observations. For these reasons, it does not cover diagnoses such as pervasive developmental disorders, speech and language disorders, or the organic brain syndromes. The DISC-IV was originally developed for use in large-scale epidemiological surveys of children and adolescents, but is now also being used in many clinical studies, screening projects, and service settings. Training for all DISC-IV interviewers is strongly recommended one to two days for the computer-assisted version, and four to five days for the paper-and-pencil version.

6 This Interviewer s Manual is designed to facilitate these trainings and to provide instruction on the proper utilization of this instrument. It provides information on the procedures that an Interviewer should follow during the administration of the instrument, as well as strategies an Interviewer can use when encountering potential difficulties. This Manual should be used as an aid to the understanding and administration of the DISC-IV. The focus of the Manual will be on the computer-assisted version (C-DISC), with specifically noted sections for the paper-and-pencil version. 3 Section 2 Computerized Versions of the DISC Three versions of the C-DISC 4 are available, all of which are copyrighted and distributed by Columbia University.
