Background There are no self-report scales that assess manic/hypomanic symptoms in patients with depression. The aim of this study was to explore the use of a modified screening instrument for bipolar disorder to assess current manic/hypomanic symptoms in patients with a depressive episode.
Results The EFA identified 3 factors: factor #1 ("elation-disinhibition-increased goal directed activity"), factor #2 ("risk-taking-impulsivity-substance use") and factor #3 (distractibility-irritability). The LCA yielded 3 classes (2 showing manic/hypomanic features). While class #1 patients endorsed more items related to disinhibition and racing thoughts, class #2 patients recognized more items associated with irritability and substance use.
Limitations Lack of an adequate gold standard measure of mixed depression to compare to, the cross-sectional design and the lack of a validation sample.
Conclusions The mHCL-32 scale allowed a comprehensive and convergent delineation of hypomanic/manic symptoms in depression. Further validation of these findings is needed.
