DSM-5 Alignment: Where the Mood Disorder Questionnaire Fits

Clinicians often ask how closely the MDQ mirrors DSM 5 bipolar criteria. Here is the quick alignment to keep in mind when reviewing results.

Symptom Overlap

The 13 MDQ items cover elevated mood, decreased need for sleep, pressured speech, racing thoughts, distractibility, increased goal directed activity, and risky behaviors—all core DSM 5 manic symptoms. The questionnaire mixes in items about irritability and spending sprees that map to the same diagnostic cluster.

What the MDQ Misses

It does not specify duration, which DSM 5 defines as at least one week for mania or four consecutive days for hypomania. The MDQ also does not parse mixed features or rapid cycling criteria, so clinicians must gather that data elsewhere.

Using the Impairment Question

DSM 5 requires marked impairment, hospitalization, or psychosis for mania. The MDQ’s final question approximates that by asking patients whether symptoms caused moderate or serious problems. Use it as a clue, then verify with detailed history.

Practical Takeaway

Treat the MDQ as a screening doorway. Once the score suggests bipolar spectrum involvement, shift into a DSM 5 based interview to confirm episode length, rule out substance effects, and document specifiers. That two step approach satisfies both clinical rigor and workflow efficiency.
