Question 1

What are the evidence-based severity cutoff scores for the HAM-D?

Accepted Answer

The most commonly cited cutoffs are 0-7 (normal), 8-13 (mild), 14-18 (moderate), 19-22 (severe), and 23+ (very severe). An empirical study by Zimmerman et al. (2013, J Affect Disord) recommended revised cutoffs: 0-7 (no depression), 8-16 (mild), 17-23 (moderate), and 24+ (severe). Both systems remain in clinical use.

Question 2

How does the HAM-D compare to the MADRS for clinical trials?

Accepted Answer

Both are widely used clinician-rated scales. The MADRS was specifically designed to be sensitive to treatment changes and is briefer (10 items vs. 17). The HAM-D is more multidimensional, covering somatic, anxiety, and insight symptoms. Many trials use both to leverage each scale's strengths.

Question 3

Is the HAM-D suitable for self-administration?

Accepted Answer

No. The HAM-D requires a trained interviewer to conduct a clinical interview and make observational ratings (e.g., psychomotor retardation, agitation). For self-report depression assessment, the PHQ-9 or BDI-II are more appropriate. If a clinician-designed scale adapted for self-report is needed, the MADRS-S is an alternative.

Question 4

What are the main criticisms of the HAM-D?

Accepted Answer

Key criticisms include: inconsistent factor structure mixing depressive, anxiety, and somatic symptoms; unequal scoring scales across items creating implicit weighting; overemphasis on insomnia (3 items); lack of a standardized interview guide in its original form; and limited empirical validation of severity cutoffs until the Zimmerman 2013 study.
