Meeting the common positive MDQ pattern suggests bipolar-spectrum symptoms may be present and supports formal mood-disorder diagnostic assessment.
Use when bipolar-spectrum symptoms are suspected, especially before initiating or escalating long-term antidepressant therapy.
Screening performance varies by setting and comorbidity. The MDQ does not replace longitudinal clinical history, collateral information, or formal diagnostic interview.
For related assessments, see PHQ-9, GAD-7 and MDI Depression Scale.
