Book excerpt: QuickSCID-5 is a briefer, more time-efficient version of the SCID designed to be administered usually in 30 minutes or less. The shorter administration time results from the fact that QuickSCID-5 consists almost entirely of closed-ended questions that can be answered "YES" or "NO" by the patient, dispensing with the requirement in the standard SCID that the interviewer elicit descriptive examples and ask enough follow-up questions until the interviewer has enough information to determine whether the DSM-5 diagnostic criteria are met.
