Your HAM-A score is a clinician's rating of 14 anxiety symptoms, added up to a total from 0 to 56. A higher total means the clinician rated your anxiety symptoms as more severe. Totals of 0 to 7 count as no or minimal anxiety. Higher totals fall in the mild, moderate or severe range.
What do HAM-A score ranges mean?
Your result uses four ranges from a four-week trial of 144 adults with generalized anxiety disorder. The study's authors called the ranges a first step and said larger studies were needed.
| Total score | Range |
|---|---|
| 0-7 | No or minimal anxiety |
| 8-14 | Mild anxiety |
| 15-23 | Moderate anxiety |
| 24-56 | Severe anxiety |
Other publications use different boundaries. The University of Florida reference form prints its own grouping. It calls totals below 17 mild, 18 to 24 mild to moderate, and 25 to 30 moderate to severe. A result should name its cutoffs instead of treating one set of ranges as universal.
A range describes where the total falls. It does not diagnose an anxiety disorder, identify the cause, measure daily functioning or choose treatment.
How is the HAM-A scored?
A clinician rates 14 symptoms from an interview and from what they observe. Each rating adds 0 to 4 points on the University of Florida reference form. You do not fill in the HAM-A yourself.
The ratings cover mental symptoms, physical symptoms, and behavior seen during the interview. Some sources group the ratings into mental and physical parts. Your result gives the total only, so it cannot show which group added more points.
Can HAM-A scores be compared over time?
Only when the clinician used the same edition, recall period, interview method and scoring convention each time. HAM-A forms can differ in their questions, anchors and interview instructions. Hamilton's original 1959 paper introduced a clinician rating for anxiety states. Later forms added edited descriptions and new interview methods.
The original method did not set one fixed recall period or provide standard follow-up questions. The interview method can change the total. A study of 89 treatment-seeking adults at three specialty sites compared two formats. A structured interview guide produced higher totals than the traditional format. Record the exact form and interview method with each result.
A lower repeated total means the ratings added up to fewer points. It does not prove recovery or explain why the change happened. A higher total also cannot prove that one condition got worse. No single change threshold fits every use of the HAM-A. A percentage drop used in one trial is a study rule, not a diagnosis or treatment rule for one person.
What else can affect a HAM-A score?
Physical ratings can overlap with medical conditions, medicine side effects or other causes. A study by Maier and colleagues found reasonably consistent ratings in its samples. It also found problems in how the items worked together and in separating some medication effects.
Depression symptoms can also add to a HAM-A total. If a clinician is separately rating depression, the HAM-D score guide explains that measure. HAM-A and HAM-D totals are not interchangeable.
Does the HAM-A ask about suicide or self-harm?
The HAM-A does not directly ask about suicide or self-harm. A low total says nothing about current safety. Safety needs its own check. Get immediate help if you may act on these thoughts or cannot keep yourself safe. Treat any other life-threatening emergency with the same urgency.
If you need help now. In the US, Call 988 or text 988. Call 911 if you are in immediate danger. Outside the US, contact your local emergency number or find support in your country.
What should I do next?
Go through the result with the clinician who rated you. Ask which symptoms scored highest or changed, and how they affect your daily life. Ask too whether health or medicine changes could have affected any physical ratings.
A questionnaire you answer yourself can help when a clinician interview is not available. The GAD-7 is one example. It is not a shorter HAM-A, so do not compare the two totals directly.
A clinician rating can add observation and follow-up questions that a questionnaire cannot. The right choice depends on who is being assessed, the purpose, any study rules and the follow-up available. Ask your clinician which suits you.
