The Schedule for Affective Disorders and Schizophrenia (SADS)[note 1] is a collection of psychiatric diagnostic criteria and symptom rating scales published in 1978.[1] 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.

Diagnoses covered

The diagnoses covered by the interview include schizophrenia, schizoaffective disorder, major depressive disorder, bipolar disorder, anxiety disorders and a limited number of other diagnoses.[1]

Relationship with the Research Diagnostic Criteria

The SADS was developed by the same group of rearchers as the Research Diagnostic Criteria (RDC). While the RDC is a list of diagnostic criteria for psychiatric disorders, the SADS interview allows diagnoses based on RDC criteria to be made, and also rates subject's symptoms and level of functioning.[1]

K-SADS

The K-SADS (or Kiddie-SADS) is a version of the SADS that is designed for school-aged children of 6–18 years.[2] The K-SADS-PL (Present and Lifetime version) is administered by interviewing the parent(s), the child, and estimating ratings which include parent, child, school and chart.[2][dead link]

Notes

  1. The SADS is not available via the major psychological test companies, but must be obtained directly from one of its coauthors, Jean Endicott, PhD, Professor of Clinical Psychology (in Psychiatry) at Columbia University Medical Center via email (je10 [at] columbia [dot] edu) or fax (212-543-5386). Keep in mind that the SADS does not map as precisely onto current nosology, i.e., DSM-5, compared to diagnostic structured interviews such as the Structured Clinical Interview for DSM-IV.
