What is Hamilton Anxiety Rating Scale (HAM-A)
The Hamilton Anxiety Rating Scale (HAM-A) is a widely used tool for measuring anxiety severity. It helps clinicians track symptom changes clearly. This scale features 14 specific items that cover a broad range of symptoms. It organises these into two main groups to give a clear picture of a patient's condition. It measures psychic anxiety, such as mental agitation, and somatic anxiety, which involves physical complaints. Each item is rated on a scale from zero to four, allowing the total score to accurately reflect the overall intensity of symptoms. Since it is a clinician-rated tool, a healthcare professional conducts the interview to ensure accuracy. This approach helps in assessing how well a treatment works over time. It is a reliable choice for clinical settings and research trials, making it easier to guide patient care plans effectively.
The Hamilton Anxiety Rating Scale (HAM-A) can be scored using one main approach based on item summation. Clinicians rate each of the 14 items on a scale from 0, meaning not present, to 4, indicating very severe symptoms. To get the total score, you just add these numbers up for a result between 0 and 56. Generally, a score below 17 suggests mild anxiety, while 18 to 24 indicates mild to moderate levels, and anything above 25 points to severe issues. This total helps doctors monitor how a patient is tracking over time.
