mood disorder questionnaire reliability and validity

The MDQ was developed as a screening tool for bipolar disorder, and assesses symptoms of mania and hypomania It was developed in the hopes that it would reduce the mis-diagnosis and delayed diagnosis of bipolar disorder. The MDQ has become one of the most widely studied and used questionnaires for bipolar disorder, and it has been translated into more than a dozen languages. In 2006, a parent-report version was created to allow for assessment of bipolar symptoms in children or adolescents from a caregiver perspective, with the research looking at youths as young as 5 years old. It takes approximately 5–10 minutes to complete. The MDQ was originally tested with adults, but it also has been studied in adolescents ages 11 years and above. It has 5 main questions, and the first question has 13 parts, for a total of 17 questions. It focuses on symptoms of hypomania and mania, which are the mood states that separate bipolar disorders from other types of depression and mood disorder. The AUCs for bipolar II disorder were 0.78 (MDQ) and 0.78 (BDSD), and the AUCs for borderline personality disorder were 0.75 (MDQ) and 0.79 (BSDS).Īmong patients being evaluated for eating disorders, the MDQ and BSDS show promise as screening questionnaires for both bipolar disorder and borderline personality disorder.The Mood Disorder Questionnaire ( MDQ) is a self-report questionnaire designed to help detect bipolar disorder. Predictive validity of the MDQ and BSDS was evaluated by Receiver Operating Characteristic analysis of the Area Under the Curve (AUC).įifteen (19%) and twelve (15%) patients fulfilled criteria for bipolar II disorder and borderline personality disorder, respectively. All participants completed the mood and eating disorder sections of the SCID-I/P and the borderline personality disorder section of the SCID-II, in addition to the MDQ and BSDS. Participants were 78 consecutive female patients who were referred for evaluation of an eating disorder. This study examined the accuracy of these scales for detecting bipolar disorder among patients referred for eating disorders and explored the possibility of simultaneous assessment of co-morbid borderline personality disorder. Screening scales for bipolar disorder including the Mood Disorder Questionnaire (MDQ) and Bipolar Spectrum Diagnostic Scale (BSDS) have been plagued by high false positive rates confounded by presence of borderline personality disorder.
