    01 - Scoring & cutoffs

    How scoring works.

    The MDQ has three parts. Part one lists 13 lifetime manic or hypomanic experiences answered yes or no; the number of "yes" answers gives a 0-13 count. Part two asks whether several of the endorsed experiences happened during the same period of time. Part three asks how much of a problem these experiences caused (no problem, minor, moderate or serious).

    A positive screen requires all three criteria at once: seven or more "yes" answers in part one, "yes" to the co-occurrence question, and "moderate" or "serious" problems in part three. The symptom count alone is not a severity score, and a positive screen is not a diagnosis - it should be followed by a clinical interview for bipolar disorder. Some distributed versions add unscored questions on family history and previous diagnosis.

    Score
    Severity
    Interpretation
    0–6
    Below symptom threshold
    Fewer than seven lifetime symptoms endorsed. Screen negative regardless of the other two questions.
    7–13
    Symptom threshold met
    Seven or more symptoms endorsed. The screen is positive only if the symptoms clustered in the same period AND caused moderate or serious problems; otherwise it is negative. A positive screen warrants a clinical interview for bipolar disorder.

    02 - Licensing, explained

    How licensing works.

    The Mood Disorder Questionnaire is copyright Robert M. A. Hirschfeld / The University of Texas Medical Branch (2000). Sales, permissions and licensing are handled by Jones & Bartlett Learning on behalf of Dr Hirschfeld's estate; widely circulated PDFs carry "reprinted with permission" notices rather than a public-domain release. We could not verify permission to reproduce the item text online, so this page does not include the questionnaire. Aisel offers a free interactive alternative on the Altman Self-Rating Mania Scale (ASRM) page, and the clinician-rated Young Mania Rating Scale (YMRS) for severity.
