Preguntas frecuentes

What is a positive MDQ score?

The MDQ is positive when: (1) 7 or more of 13 symptom questions are answered 'Yes', AND (2) several symptoms occurred during the same period, AND (3) symptoms caused moderate or serious problems. All three criteria must be met.

What does the MDQ screen for?

The MDQ screens for bipolar spectrum disorder, including Bipolar I, Bipolar II, and cyclothymia. It was developed to identify patients who may have been misdiagnosed with unipolar depression.

Who developed the MDQ?

The MDQ was developed by Robert Hirschfeld, MD and colleagues, and validated in the American Journal of Psychiatry (2000). It demonstrated a sensitivity of 73% and specificity of 90% in a specialty bipolar outpatient clinic sample (PMID 11058490). Performance may be lower in primary care and general population settings, where bipolar prevalence is lower and false-positive rates are higher.

Can the MDQ miss bipolar II disorder?

The MDQ has lower sensitivity for bipolar II than bipolar I because hypomania symptoms are milder. A negative MDQ does not rule out bipolar II. Clinical interview remains essential for accurate diagnosis.

Should the MDQ replace a clinical interview?
