- For adults
These tests are for screening. A result is not a diagnosis: only a psychiatrist or psychologist can make one, after talking with you.
Your answers are scored on this device and never sent. Only your result is saved, with the email address you confirm.
Confirm your email address
Before the test we send a 6-digit code to your email address. Your result is saved with it, so that our team can help you if you wish. The email with the code contains no health information.
Each group below contains four statements. Read each group carefully and choose the statement that best describes how you have been feeling over the past week, including today.
Choosing an answer takes you to the next question. You can go back at any time.
Your result
No notable depressive symptoms
Your score does not point to notable depressive symptoms. Feeling low or tired now and then is normal. If you start to feel different, you can take the test again later or talk to a professional.
Mild depressive symptoms
Your score points to mild depressive symptoms. Looking after daily routines such as sleep, physical activity and time with people close to you can help. If the symptoms last longer than two weeks or get worse, it is a good idea to see a professional.
Moderate depressive symptoms
Your score points to moderate depressive symptoms. Symptoms at this level often affect daily life, and they usually ease considerably with treatment. We recommend that you see a psychiatrist.
Severe depressive symptoms
Your score points to severe depressive symptoms. We recommend that you see a psychiatrist soon; depression is a treatable illness, and with the right treatment the symptoms usually ease considerably.

Take your result as a rough guide, not a diagnosis. How you feel over time, and a conversation with a specialist, tell much more than a questionnaire.
Talk it through with a specialist
If your result worries you, or you would like to talk it through, our psychiatrists can review it with you, free and without obligation.
