About This Bipolar Test

This bipolar test is based on the MDQ (Mood Disorder Questionnaire), developed by Hirschfeld and colleagues (2000) and validated across multiple clinical populations. The MDQ is specifically designed to screen for bipolar spectrum disorder, including Bipolar I, Bipolar II, and Cyclothymia, rather than unipolar depression, making it the most diagnostically specific brief bipolar screener available.

The MDQ uses a 3-part positive screen criterion: (1) ≥7 of 13 symptoms endorsed as "yes", (2) several symptoms co-occurred during the same time period, and (3) the symptoms caused at least moderate problems. All three must be met for a positive screen. This specificity minimizes false positives from unipolar depression, anxiety, or substance use.

Bipolar disorder affects approximately 2.4% of the global population and has an average diagnostic delay of 6–10 years. During this period patients are often misdiagnosed with unipolar depression, leading to monotherapy with antidepressants, which can precipitate manic episodes. Early, accurate detection is critical for appropriate treatment (mood stabilizers, atypical antipsychotics, and bipolar-specific psychotherapy).
