The Mood Disorder Questionnaire (MDQ) is a screening tool to check if you have Bipolar Disorder. MDQ can be administered either by a medical professional or by yourself (self administered).

Often the depressed mood in Bipolar Disorder is misdiagnosed as depression. It can take 7 to 10 years for a correct diagnosis! Imagine the toll it takes on a person taking antidepressants without any mood stabilizer for the mania part of Bipolar Disorder. Bipolar Disorder has diverse symptoms, but the most noticeable ones are impulsive behaviour, alcohol or substance abuse, fluctuations in energy level, and legal problems (usually caused during the manic phase). One way to improve recognition and treatment of Bipolar Disorder is to screen for it using the MDQ.


The Mood Disorder Questionnaire (MDQ) is a brief screening questionnaire and takes about five minutes to complete. It can be self-administered, which means you can do it yourself. 

A screening test is different from a diagnostic test. A screening test like the MDQ identifies possible symptoms and alerts you to the need for a follow-up with a medical professional. It’s not a formal diagnosis. A diagnostic test involves many steps and long face-to-face consultations with a medical professional. Remember, the MDQ is only a screening test.

Clinical trials have indicated that the MDQ has a high rate of accuracy. It can identify seven out of ten people who have bipolar disorder and screen out nine out of ten people who do not. The MDQ screens the complete spectrum of Bipolar Disorder (Bipolar I, Bipolar II and Bipolar NOS).

Below is the free MDQ download. Instructions on how to score the questionnaire is included.



The tests provided here are for screening only. A positive screen does not mean you have bipolar disorder – just that you should follow-up with an expert!
