Hamilton Depression Rating Scale. Extracted from Regular and Change Versions of the Schedule for Affective Disorders and Schizophrenia

Arch Gen Psychiatry. 1981 Jan;38(1):98-103. doi: 10.1001/archpsyc.1981.01780260100011.


Investigators who wish to use new procedures usually wish to relate their results to those already in the literature. This often results in the use of both old and new measures. The Schedule for Affective Disorders and Schizophrenia Regular and Change Versions (SADS and SADS-C) have advantages over the widely used Hamilton Depression Rating Scale (HDRS). A procedure was developed to extract the HDRS score from the SADS and SADS-C. The comparative reliability and the validity of the extracted HDRS score as a substitute for a real HDRS score was established. The SADS-C and the HDRS were completed by the raters for 48 subjects. The correlation between the extracted and real HDRS scores was positive and large.
