The Montgomery-Åsberg Depression Rating Scale (MADRS) is a ten-item clinician-rated measure of depression severity, designed to be sensitive to change in treatment trials. It emphasizes the core psychological symptoms of depression and deliberately under-weights somatic items, which makes it well suited to reading depressive content out of an interview transcript.
Each item is evidence-mode: highlight the passage in the subject's speech (or the interviewer's observation of the subject) that supports the rating — reported sadness, inner tension, loss of interest, pessimism, suicidal ideation, and so on. One item, Apparent Sadness, is rated from observable dejection rather than self-report; annotate the described presentation. Rate only the subject, never the interviewer's prompts.
