Which tool is used to screen for Bipolar Disorder?

The Mood Disorder Questionnaire (MDQ) is specifically designed to screen for bipolar disorder. It evaluates a person's history of mood symptoms, including episodes of depression and mania or hypomania. The MDQ consists of a series of questions that assess the presence, duration, and impact of mood episodes, making it a valuable tool for identifying potential bipolar disorder in individuals.

The other tools listed are not appropriate for screening bipolar disorder. The Beck Depression Inventory focuses primarily on depressive symptoms and does not assess manic or hypomanic symptoms essential for diagnosing bipolar disorder. Cohen's Perceived Stress Scale measures perceived stress rather than mood episodes, while the Generalized Anxiety Disorder 7-item scale (GAD-7) specifically screens for generalized anxiety disorder, making them less suitable for identifying bipolar disorder.
