Interpretation/scoring

Interpretation/scoring

Major depression is diagnosed if ≥5 of the 9 symptoms (items 4 and 5 combined) have been present in the past two weeks and if symptom 1 or 2 are included in these 5 symptoms.

A more precise major depression diagnosis depends on the answer to item 9 (a) or (b) and to item 10 (a) or (b).

  • Major depression without inverse neurovegetative symptoms: a score on 9a and 10a.
  • Major depression with inverse neurovegetative symptoms: a score on 9b and 10b.
