    Facts & Figures

    QIDS Scoring Information:

    • Collect responses to all questions.
    • Use the highest score on any 1 of the 4 sleep symptoms (items 1 to 4).
    • Use the highest score on any 1 of the 4 weight symptoms (items 6 to 9).
    • Use the highest score on either of the 2 psychomotor symptoms (items 15 and 16).
    • There will be one score for each of the nine depression symptoms.
    • Add the scores of the of the 14 items as instructed above pertaining to the 9 depression symptoms (sleep, mood, weight, concentration, guilt, suicidal ideation, interest, fatigue and psychomotor changes) to obtain the total score. Total scores range from 0-27.

    Score interpretation:

    • The higher the score, the more severe the depression.
    • Scores ≤5 indicate no depression.
    • Scores of 6-10 indicate mild depression.
    • Scores of 11-15 indicate moderate depression.
    • Scores of 16-20 indicate severe depression.
    • Scores ≥21 indicate very severe depression.
