The Mood Disorder Questionnaire (MDQ) is a self-report psychological questionnaire designed to identify mood symptoms often found in bipolar disorder and their degree of impairment in children and adolescents ages 12 and above. The 5-question test is filled out by the child and takes approximately 5–10 minutes to complete. The MDQ has shown good reliability and validity in assessing child bipolar symptoms in recent studies.[1][2]

Development

The MDQ was developed as a screening tool for bipolar disorder, and assesses for lifetime symptoms of mania and hypomania.[2] It was developed in the hopes that it would reduce the mis-diagnosis and delayed diagnosis of bipolar disorder in children and adolescents.[2]

Question breakdown, scoring, and interpretation

The first question identifies 13 common mood and behavior symptoms and asks if the child has experienced any of them, and the second question asks if these symptoms have ever occurred at the same time. The third question asks to what degree of impairment the symptoms have on the child, on a scale of “no problem,” “minor problem,” “moderate problem,” to “serious problem.” The last two questions address if a family history of bipolar disorder exists and if a diagnosis of bipolar disorder has already been determined.

Only responses to the first three are factored in the total score. The questionnaire suggests a higher risk for bipolar disorder if the child reports the presence of 7 or more symptoms, reports the co-existence of multiple symptoms, and reports degree of impairment as a “moderate” to “serious problem.”

Psychometrics

The MDQ, particularly the parent report of the MDQ, possesses good sensitivity and specificity in discriminating bipolar versus non-bipolar cases.[3] However, the measure may not be as sensitive to milder behaviors of bipolar disorder.[4]
