    Yalin Sapmaz, S; Yalin, N; Özek Erkuran, H; Öztekin, S; Uzel Tanriverdi, B; Köroglu, E; Aydemir, Ö
    Objective: This study aimed to assess the validity and reliability of the Turkish version of DSM-5 Depression Severity Scale-Child Form. Methods: The scale was prepared by carrying out the translation and back-translation of DSM-5 Depression Severity Scale-Child Form. Study group consisted of 46 patients that have been treated in a child psychiatry unit and diagnosed with depressive disorder and 135 healthy volunteers that were attending middle or high school during the study period. For the assessment, Child Depression Inventory (CDI) was used along with DSM-5 Depression Severity Scale-Child Form. Results: Regarding reliability analyses, Cronbach's alpha internal consistency coefficient was calculated as 0.911 while item-total score correlation coefficients were measured between 0.579 and 0.801. As for construct validity, a factor that could explain 59.2% of the variance was obtained and was consistent with the original structure of the scale. In the concurrent validity analysis, the scale showed a high correlation with Child Depression Inventory with a correlation coefficient value measured as r=0.847. Conclusion: It was concluded that Turkish version of DSM-5 Depression Severity Scale-Child Form could be utilized as a valid and reliable tool both in clinical practice and for research purposes.

    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.

    Validity and Reliability of the Turkish Version for DSM-5 Level 2 Anger Scale (Child Form for Children Aged 11-17 Years and Parent Form for Children Aged 6-17 Years)
    Yalin Sapmaz, S; Özek Erkuran, H; Yalin, N; Önen, Ö; Öztekin, S; Kavurma, C; Köroglu, E; Aydemir, Ö
    Introduction: This study aimed to assess the validity and reliability of the Turkish version of Diagnostic and Statistical Manual of Mental Disorders (DSM-5) Level 2 Anger Scale. Methods: The scale was prepared by translation and back translation of DSM-5 Level 2 Anger Scale. Study groups consisted of a clinical sample of cases diagnosed with depressive disorder and treated in a child and adolescent psychiatry unit and a community sample. The study was continued with 218 children and 160 parents. In the assessment process, child and parent forms of DSM-5 Level 2 Anger Scale and Children's Depression Inventory and Strengths and Difficulties Questionnaire-Parent Form were used. Results: In the reliability analyses, the Cronbach alpha internal consistency coefficient values were found very high regarding child and parent forms. Item-total score correlation coefficients were high and very high, respectively, for child and parent forms indicating a statistical significance. As for construct validity, one factor was maintained for each form and was found to be consistent with the original form of the scale. As for concurrent validity, the child form of the scale showed significant correlation with Children's Depression Inventory, while the parent form showed significant correlation with Strengths and Difficulties Questionnaire-Parent Form. Conclusion: It was found that the Turkish version of DSM-5 Level 2 Anger Scale could be utilized as a valid and reliable tool both in clinical practice and for research purposes.
