It may be simple to tell if you have a cold or a headache, but it may not be as obvious when you have mental health difficulties. The Patient Health Questionnaire-9 (PHQ-9) is a self-assessment tool for signs of Depression. It is a valid assessment tool and can indicate if you need to consider getting a Diagnostic Assessment and support.

The Patient Health Questionnaire-9 (PHQ-9) is not a diagnostic tool and is not intended to replace a consultation with an appropriately trained professional.

Please read each question carefully before selecting a response.

(The PHQ-9 was developed by Drs. Robert L. Spitzer, Janet B.W. Williams, Kurt Kroenke and colleagues, with an educational grant from Pfizer Inc.)
