HAM-A rating scores

This anxiety model is clinician rated and is scored based on the five choices given for each of the 14 criteria. The clinician uses observation to identify how the patient experiences or displays each of the areas of focus. The five point ratio scale is discussed below:

■ 0 – not present;

■ 1 – mild prevalence of the symptoms or feelings;

■ 2 – moderate prevalence of the feelings or symptoms;

■ 3 – severe display of feelings and symptoms;

■ 4 – very severe prevalence of the feelings, symptoms in the patient.

HAM-A result interpretation

The total of the evaluation comprises of the sum of the scores for each criteria which is between 0 to 56. Scores of 17 or below indicate mild anxiety severity. Scores between 18 and 24 suggest a mild to moderate stage while score between 25 and 30 are indicative for a moderate to severe anxiety severity. What is above 30 means very severe anxiety.

An example of a result would be: According to the Hamilton Anxiety Rating Scale the answers provided in the HAM-A questionnaire are indicative of a mild to moderate severity anxiety condition.

Anxiety as a symptom, as a disorder

Anxiety is defined first as an emotion that is characterized by an inner state of turmoil, worry and even fear. It is often accompanied by somatic symptoms because of the fight or flight reaction of the human body.

Whilst it is normal to feel anxious at times and at unease in certain situations there is a limit to where the normal ends and pathologic begins and where anxiety becomes a serious symptom of a mental illness.

The specific one is called generalized anxiety disorder (GAD) but there are several conditions displaying anxiety as a symptom like different specific phobias, meaning fears, panic disorder with panic attacks or the social anxiety disorder also known as social phobia.
