When to use
Quantifying and tracking the severity of depressive symptoms over time in patients with suspected or known major depressive disorder.
Formula
Sum of 9 DSM symptom-domain scores (each 0-3). Sleep, appetite/weight, and psychomotor domains are each defined by the instrument as the highest-scoring of several component symptoms (e.g., insomnia vs. hypersomnia) within that domain. Total range 0-27.
Pearls and pitfalls
Score the sleep, appetite/weight, and psychomotor items using whichever component symptom is most severe for that patient.
A self-report severity tracker, not a diagnostic interview; item 6 (suicidal ideation) always warrants direct clinical follow-up regardless of total score.
