    Background: Mixed depression is a common, dimensional phenomenon that is increasingly recognized in unipolar and bipolar disorders. We piloted a modified version of the Hypomania Checklist (mHCL-32) to assess the prevalence and clinical correlates of concurrent manic (hypo) symptoms in depressed patients. Methods: The mHCL-32, Young Mania Rating Scale (YMRS) and Hamilton Rating Scale for Depression (IAMD-24) were utilized in the assessment of unipolar (UP=61) and bipolar (BP=44) patients with an index major depressive episode confirmed by the Structured Clinical Interview for DSM-IV (SCID). Differential mHLC-32 item endorsement was compared between UP and BR Correlation analyses assessed the association of symptom dimensions measured by mHCL-32, YMRS and HAMD-24. Results: There was no significant difference between mood groups in the mean rnHCL-32 and YMRS scores. Individual mHLC-32 items of increased libido, quarrels, and caffeine intake were endorsed more in BP vs. UP patients. The mHCL-32 active elevated subscale score was positively correlated with the YMRS in BP patients and negatively correlated with HAMD-24 in UP patients. Conversely, the mHCL-32 irritable risk taking subscale score was positively correlated with HAMD-24 in BP and with YMRS in UP patients. Limitations: Small sample size and cross-sectional design. Conclusion: Modifying the HCL to screen for (hypo) manic symptoms in major depression may have utility in identifying mixed symptoms in both bipolar vs. unipolar depression. Further research is encouraged to quantify mixed symptoms with standardized assessments. (C) 2013 Published by Elsevier B.V.

    Different patterns of manic/hypomanic symptoms in depression: A pilot modification of the hypomania checklist-32 to assess mixed depression
    Prieto, ML; Youngstrom, EA; Ozerdem, A; Altinbas, K; Quiroz, D; Aydemir, O; Yalin, N; Geske, JR; Feeder, SE; Angst, J; Frye, MA
    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. Methods: The study sample consisted of 188 patients with Structured Clinical Interview for DSM-IV-TR disorders (SCID) confirmed bipolar or major depressive disorder. We modified the Hypomania Checklist-32 (mHCL-32) to assess current instead of lifetime symptoms. An Exploratory Factor Analysis (EFA) was conducted to identify clusters of mHCL-32 items that were endorsed concurrently. A Latent Class Analysis (LCA) was carried out to identify groups of patients with similar mHCL-32 item endorsement patterns. Results: The EPA 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. (C) 2014 Elsevier B.V.
