Hirschfeld 2000 Mood Disorder Questionnaire (MDQ)

Hirschfeld 2000 Mood Disorder Questionnaire (MDQ): thirteen caller-assigned yes/no lifetime manic/hypomanic items, 1 point each, max 13. Positive screen requires score ≥7 AND same_period AND moderate_or_serious_problem (that paper: sensitivity 0.73 and specificity 0.90 in a psychiatric outpatient sample). Not a bipolar diagnosis, not a medical device, and not Hirschfeld 2003 general-population cutoff tweaks. magent does not interview the patient.
