Relationship with the Research Diagnostic Criteria
The SADS was developed by the same group of researchers 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.
K-SADS
The K-SADS (or Kiddie-SADS) is a version of the SADS adapted for school-aged children of 6–18 years. There are various different versions of the K-SADS, each varying slightly in terms of disorders and specific symptoms covered, as well as the scale range used. All of the variations are still semi-structured interviews, giving the interviewer more flexibility about how to phrase and probe items, while still covering a consistent set of disorders.
The K-SADS-E (Epidemiological version) was developed for epidemiological research. It focused on current issues and episodes only. Most of the items used a four-point rating scale.
The K-SADS-PL Archived 2016-04-18 at the Wayback Machine (Present and Lifetime version) is administered by interviewing the parent(s), the child, and integrating them into a summary rating that includes parent report, child report, and clinical observations during the interview. The interview covers both present issues (i.e., the reason the family is seeking an evaluation) as well as past episodes of the disorders. Most items use a three-point rating scale for severity (not present, subthreshold, and threshold—which combines both moderate and severe presentations). It has been used with preschool as well as school-aged children. A 2009 working draft removed all reference to the DSM-III-R criteria (which were replaced with the publication of the DSM-IV in 1994) and made some other modifications. A DSM-5 version is being prepared and validated.
The WASH-U K-SADS (Washington University version) added items to the depression and mania modules and used a six-point severity rating for severity.
