What does the HAM-A total score mean?

Scores of 0–7 indicate minimal or no anxiety, 8–17 indicate mild anxiety, 18–24 indicate moderate anxiety, and 25–30+ indicate severe anxiety. Clinical guidelines may vary slightly by context.

Is this a self-assessment tool?

The HAM-A was designed for clinician administration, not self-scoring. A trained clinician rates each item based on clinical interview and observation. This calculator helps tally the score but does not replace professional evaluation.

What do the 14 items measure?

The first 6 items measure psychic anxiety (anxious mood, tension, fears, insomnia, cognitive difficulties, depressed mood) and items 7–14 measure somatic anxiety (muscular, sensory, cardiovascular, respiratory, gastrointestinal, genitourinary, autonomic, and observed behavior at interview).

How long does the HAM-A take?

A structured HAM-A interview typically takes 10–20 minutes. Scoring itself takes under a minute once ratings are assigned.

Who developed the HAM-A?

The scale was developed by Max Hamilton and first published in 1959. It remains one of the most widely used rating scales in anxiety disorder research and clinical practice.

Summary

Rate each of the 14 HAM-A items from 0–4 to calculate your total anxiety severity score with interpretation.

How it works

Read each of the 14 symptom items carefully.
Select a severity rating from 0 (not present) to 4 (very severe) for each item.
The tool sums all ratings as you score each item.
Review your total score and the corresponding severity band.
Use the score alongside clinical judgment — the HAM-A is a clinician-rated scale, not a self-diagnosis tool.

Use cases

Screening patients for anxiety severity before treatment.
Tracking changes in anxiety symptoms across therapy sessions.
Standardizing anxiety measurement in clinical research.
Documenting pre- and post-treatment anxiety levels.
