Preview of the 21 questions
Scoring & interpretation
The questionnaire consists of 21 items assessing depressive symptoms. Each item is scored from 0 to 3 according to the intensity of the reported symptom, giving a total score between 0 and 63.
The higher the total score, the more severe the depressive symptomatology; standardized cutoffs are then used to determine severity (minimal, mild, moderate, or severe).
