The Hamilton Rating Scale for Depression has become a popular instrument for quantifying clinical assessments of the severity of depression in psychiatric research, and data on its psychometric properties continue to accumulate. Data are presented on item interrater reliability, internal consistency, concurrent validity, and ability to differentiate depressed from non-depressed groups. Recommendation for a reduced scale and for anchoring point guidelines are made.
