HAM-A

Clinical Scales

The HAM-A is a clinician-administered scale that measures the severity of a patient’s anxiety, based on 14 parameters that include anxious mood, tension, fears, insomnia, somatic complaints, and behavior. The scale predates the current definition of generalized anxiety disorder (GAD); however, it covers many of the features of GAD and can also be helpful in assessing its severity.

The HAM-A is primarily used to document the results of treatment, rather than as a diagnostic or screening tool. It is scored on 5 points: 0 (not present) to 4 (severe).

The HAM-A was developed by Professor Max Hamilton.
