The Hamilton Anxiety Rating Scale (HAM-A) is a clinician-rated tool designed to assess the severity of anxiety symptoms in adults, adolescents, and children. Developed by Max Hamilton in 1959, it consists of 14 items measuring both psychic and somatic anxiety, with scores ranging from 0 to 56. The scale categorizes severity into mild, moderate, and severe levels. Despite its widespread use in clinical and research settings, it has faced criticism for its ability to differentiate between various effects of treatments. The HAM-A is available in multiple languages and is in the public domain.
