Schedule for Affective Disorders and Schizophrenia

The Schedule for Affective Disorders and Schizophrenia (SADS) is a collection of psychiatric diagnostic criteria and symptom rating scales published in 1978. There are three versions of the schedule, the regular SADS, the lifetime version (SADS-L) and a version for measuring change in symptomology (SADS-C). Although largely replaced by diagnostic criteria such as DSM-IV, and specific mood rating scales, SADS is still used in some research papers today.
