Sum the two PHQ-2 items scored 0–3 over the past two weeks.
| PHQ-2 | – |
Use this calculator to add little interest or pleasure and feeling down, depressed, or hopeless. Each item is 0 not at all, 1 several days, 2 more than half the days, 3 nearly every day, for a total of 0–6. A score of 3 or more is a common threshold to continue to PHQ-9. This is a two-item screen, not a diagnosis and not the full PHQ-9.
Little interest: Anhedonia item, 0–3.
Feeling down: Depressed-mood item, 0–3.
PHQ-2: Sum of the two items.
