What is the MDQ questionnaire?

The MDQ (Mood Disorder Questionnaire), developed by Hirschfeld, is a screening tool for the bipolar spectrum. It focuses on periods when mood becomes unusually elevated, expansive or irritable, alongside extra energy, reduced sleep and increased activity. It aims to spot these phases that are sometimes mistaken for simply a good stretch.

Why it matters

Bipolar disorder is often mistaken for depression, because people usually seek help during the low phases. Spotting possible high phases is essential for the right support. Telling apart the highs and lows of mood also helps you understand yourself better day to day, at work and in relationships.
