Understanding the Hamilton Rating Scale for Depression (HAM-D)
What Is the HAM-D?
The Hamilton Rating Scale for Depression was developed by Dr. Max Hamilton in 1960 to quantify the severity of depressive symptoms. It remains one of the most frequently used depression assessment tools in clinical research and practice due to its reliability and validity.
Key features of HAM-D include:
- Clinician-administered assessment
- Focus on symptom severity rather than diagnosis
- Used to monitor treatment progress and response
Purpose of the HAM-D
The primary purposes of the HAM-D are:
- To evaluate the severity of depression at baseline
- To monitor changes over time during treatment
- To assist in clinical decision-making
- To enable standardized reporting in research studies
Structure and Components of HAM-D
The traditional HAM-D consists of 17 items (HAM-D17), with some versions including additional items. The core 17-item version assesses various domains, such as mood, guilt, suicidal ideation, sleep disturbances, anxiety, and somatic symptoms.
The 17 items cover:
1. Depressed Mood
2. Feelings of Guilt
3. Suicide
4. Insomnia (Early)
5. Insomnia (Middle)
6. Insomnia (Late)
7. Work and Activities
8. Psychomotor Retardation
9. Agitation
10. Anxiety (Psychic)
11. Anxiety (Somatic)
12. Somatic Symptoms (Gastrointestinal)
13. General Somatic Symptoms
14. Genital Symptoms
15. Hypochondriasis
16. Loss of Weight
17. Insight
Each item is scored on a 3- or 5-point scale, with higher scores indicating more severe symptoms. The total score helps classify depression severity as mild, moderate, severe, or very severe.

Interpreting HAM-D Scores
Severity Classifications
The total HAM-D score helps classify depression severity as follows:
| Score Range | Severity Level |
|---------------|------------------------|
| 0–7 | Normal/No depression |
| 8–13 | Mild depression |
| 14–18 | Moderate depression |
| 19–22 | Severe depression |
| ≥23 | Very severe depression|
Note: These thresholds can vary slightly depending on the study or clinical guidelines.
Using HAM-D Scores in Treatment
- Baseline measurement: Establish initial severity before treatment begins.
- Monitoring progress: Conduct regular assessments to track symptom changes.
- Adjusting treatment: Use score trends to decide on medication adjustments or therapy modifications.
- Evaluating remission: A score below 7 generally indicates remission.
