The Mood Disorder Questionnaire (MDQ) is a brief self-report screening instrument for bipolar spectrum disorders, which include bipolar I, bipolar II, and bipolar disorder not otherwise specified. The MDQ screens for a lifetime history of a manic or hypomanic syndrome by including 13 yes/no items derived from both the DSM-IV criteria and clinical experience.

Bipolar Disorder
The purpose of the evaluation is to:
Self-administered
Clinical
Questionnaire
18 years and above
Less than 5 minutes
Since the questionnaire relies on client self-report, all responses should be verified by the clinician, and a definitive diagnosis is made on clinical grounds taking into account how well the client understood the questionnaire, as well as other relevant information from the client.
This instrument is designed for screening purposes only and is not to be used as a diagnostic tool.
In order to screen positively for bipolar spectrum disorder, in addition to a threshold number of symptom items, the respondent had to check “yes” for the item asking if the symptoms clustered in the same time period and had to indicate that the symptoms caused either “moderate” or “serious” problems.
By using this 7-or-more-item threshold, seven out of 10 people with a bipolar spectrum disorder would be correctly identified by the Mood Disorder Questionnaire, whereas nine out of 10 of those who did not have a bipolar spectrum disorder would be successfully screened out.
