Depression Questionnaire (PHQ-9)
This easy-to-use questionnaire measures your depression level based on how you answer 9 questions. You’ll get a score and explanation at the end.
The Patient Health Questionnaire (PHQ) was developed by Drs Spitzer, Williams and Kroenke and funded by Pfizer. It is an NHS-approved tool used to assess the severity of depression and inform treatment options. No permission is required to reproduce, display or distribute the PHQ-9.
