This brief questionnaire will quickly assess whether or not you have depression and how severe it is. It is based on the Patient Health Questionnaire (PHQ-9) and it uses the DSM-IV depression diagnostic criteria to determine the results.

This assessment only takes a couple minutes and can be taken repeatedly over time to assess improvement or worsening of symptoms in response to treatment.

To make a diagnosis of depression, physical causes, normal bereavement, and a history of manic/hypomanic episodes must be ruled out.

To take this assessment, select how often you have experienced the following problems over the last 2 weeks.
