The Hamilton Depression Rating Scale—also called HAM-D, HDRS, or HRSD—is a clinician-rated tool developed by Max Hamilton in 1960 to quantify the severity of depressive symptoms and monitor change over time. It remains one of the most commonly used outcome measures in depression research and specialist practice, especially for evaluating treatment response.
