mood disorder questionnaire reliability and validity

Įarly identification of BD is essential for appropriate treatment. On average, the duration of undiagnosed, hence untreated, BD may last up to 10 years, and there is some evidence that up to one-third of patients with BD are misdiagnosed at least once during their lifetime. Minor hypomanic episodes are often overlooked, and, indeed, the differentiation of clinically elated and irritable mood or increased activity from “normal” variation in the population is often challenging. Because of its course characterized by recurring episodes separated by periods of euthymia with no or scant symptoms of hypomania, BD may persist undiagnosed for a long time unless a frank episode of mania erupts. This may lead to adverse consequences, such as increased suicide risk, greater probability of hospitalization, poorer response to antidepressants, and antidepressant-induced switch to mania. Since the first episode of a BD is often of a depressive kind, BD is often misdiagnosed as major depressive disorder (MDD) and treated as such.

Conclusionīoth screeners work best in excluding the presence of BD in patients with MDD, which is an advantage in deciding whether or not to prescribe an antidepressant.īipolar disorder (BD) is a severe mental disorder with a chronic-recurring course. Both were able to distinguish patients diagnosed with BD from putatively healthy controls, and equally able to distinguish patients diagnosed with BD from patients with MDD. The bifactor implementation of the most reported two-factor model had the best fit for both screeners. Reliability was good for both tools in all samples. Receiver Operating Characteristic analysis was used to assess the capacity of the translated screeners to distinguish patients with BD from those with MDD and controls. Confirmatory factor analysis was applied to show that a single global score was an appropriate summary measure of the screeners in the sample. The sample included 59 patients with BD, 86 with unipolar Major Depressive Disorder (MDD) and 281 controls. This study aimed to explore the reliability, factor structure, and criterion validity of their Arabic versions in a sample of Tunisian patients diagnosed with mood disorders. Studies about the two most used and validated instruments for the early detection of Bipolar Disorder (BD), the 32 - item Hypomania Checklist (HCL - 32) and the Mood Disorder Questionnaire (MDQ), are scarce in non-Western countries.
