MDQ [Mood Disorder Questionnaire]

The MDQ is a brief screening instrument for bipolar disorder. It asks about the lifetime presence of 10 symptoms of mania, and so is most sensitive for bipolar I disorder.

Created by Drs. Robert M.A. Hirschfeld, Janet B.W. Williams, Robert L. Spitzer and colleagues. The scale has been published by the authors and widely distributed, though Dr. Hirschfeld retains copyright.
