Depression Severity Score

Minimal symptomsMild symptomsModerate symptomsModerately severe or higher

0-2 across these five items suggests minimal depressive symptoms this period. On the full PHQ-9 a total under 5 is the 'minimal' band; persistent symptoms still warrant a clinician's input.

These five items mirror the PHQ-style 0-3 scoring; on the validated PHQ-9 (max 27) cutoffs are 5/10/15/20, but this 5-item version maxes at 15, so bands are scaled proportionally and remain a screen, not a diagnosis.
