PHQ-9 Depression Test
The Patient Health Questionnaire-9 is a brief, validated depression screener used in primary care worldwide. Answer nine questions to see your score and interpretation.
How the PHQ-9 is scored
Each of the nine items is rated 0 (Not at all) to 3 (Nearly every day) based on how often it bothered you over the last two weeks. Item scores are summed for a total between 0 and 27.
- 0 – 4 — Minimal depression
- 5 – 9 — Mild depression
- 10 – 14 — Moderate depression
- 15 – 19 — Moderately severe depression
- 20 – 27 — Severe depression
A cutoff score of 10 is the standard threshold suggesting further evaluation. At this cutoff the PHQ-9 has 88% sensitivity and 88% specificity for major depression (Kroenke et al., 2001).
Over the last 2 weeks, how often have you been bothered by any of the following problems?
