    Relationship of levetiracetam and obsessive-compulsive disorder: A case report
    (Taylor and Francis Ltd., 2017) Çökmüş F.P.; Aşçıbaşı K.; Öztekin S.; Demet M.M.
    Levetiracetam has gained wide acceptance in the treatment of epilepsy due to its broad-spectrum efficacy, the lack of significant drug–drug interactions, and a relatively benign side effect profile. However, in recent years, the treatment of epilepsy using levetiracetam has been associated with psychiatric side effects such as anxiety, irritability, hostility, depression, hallucinations, and, in some rare cases, obsessive-compulsive disorder. In this case report, we present and discuss onset of obsessive-compulsive disorder symptoms in a 55-year-old epileptic female patient, who did not have any previous psychiatric disorder, including obsessive-compulsive disorder, and who received levetiracetam treatment. © 2017 The Author(s).

    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. © 2017, Cukurova University, Faculty of Medicine.

    Objective: This study aimed to demonstrate the reliability and validity of the Turkish form of DSM-5 Severity Measure for Specific Phobia Scale which was developed according to DSM-5 criteria to measure the severity of specific phobia. Methods: This study was carried out with patients with a diagnosis of any anxiety disorder according to DSM-5 criteria who are under treatment in Celal Bayar University Faculty of Medicine Psychiatry Inpatient or Outpatient Clinics. Patients with any mental or physical disease except for anxiety disorders were excluded. Accordingly, 50 patients with anxiety disorder were included in the study. One hundred and three volunteers without any mental or physical disease were included as healthy control group. Beside DSM-5 Severity Measure for Specific Phobia Scale the most widely used self-rated scale, Spielberger’s State-Trait Anxiety Inventory was used for concurrent validity. In reliability analyses internal consistency coefficient and item-total correlation analysis; in validity analyses factor analysis and correlation analysis with the Pearson Correlation Analysis were performed. Results: The mean age of the study group was 29.0±11.8 and 60.1% of the sample group (n=92) were female. 66.0% of the sample group were college graduates, 12.4% high school graduates, 21.6% were also primary school graduates. Disease duration of anxiety disorder group was 5.8±7.0 years. The internal consistency of the DSM-5 Severity Measure for Specific Phobia Scale was 0.79 and item-total correlation coefficients were between 0.33 and 0.78. In the explanatory factor analysis, for sample adequacy Kaiser-Meier-Olkin coefficient was calculated as 0.88 and Bartlett coefficient was 1.01. Double-factor solution was obtained and the eigenvalues were 5.45 and 1.26, explaining 67.20% of the total variance. Factor loadings of the items were between 0.43 and 0.88. Coefficient of correlation analysis with Spielberger’s State-Trait Anxiety Inventory was calculated as r=0.36. Conclusion: These findings have been shown that the DSM-5 Severity Measure for Specific Phobia Scale is reliable and valid for Turkish. © 2017, Cukurova University, Faculty of Medicine.

    (Cukurova University, Faculty of Medicine, 2017) Sücüllüoğlu Dikici D.; Aşçibaşi K.; Aydemir Ö.; Balikçi K.; Akdeniz F.; Çöldür E.Ö.; Yüzeren S.; Alçi D.; Çökmüş F.P.; Öztekin S.; Aydin O.; Sarikavak T.; Herdem A.; Aydin Aşik E.; Köroğlu E.
    Objective: This study aims to demonstrate the reliability and validity of Turkish version of DSM-5 Depression Scale which was developed to measure the severity of depression. Methods: The study group included 50 in- or out-pa- tients who met the criteria for major depressive disorder according to DSM-5. Sixty-three healthy volunteers without any mental or physical disease were also recruited as a control group. Beck Depression Inventory (BDI), which is the most widely used self-report scale, was used for concurrent validity. Internal consistency coefficient Cronbach alfa and item-total correlation analysis were performed for reliability. Exploratory factor analysis was used for validity, as BDI was used for concurrent validity. Results: Mean age was 39.2±11.3 and 22.4±5.8 years in the patient and control group, respectively. Sixty-one percent of the sample group (n=66) were female. 64.8% of the group were college graduates, 19% were primary school graduates and 18.5% were high school graduates. Disease duration for major depressive disorder was 3.3±5.6 years for the patient group. For the internal consistency Cronbach alfa coefficient of the DSM-5 Depression Scale was 0.91. Item-total correlation coefficients were between 0.60-0.83. For the exploratory factor analysis of sample adequacy of DSM-5 Depression Scale, Kaiser-Meier-Olkin (KMO) coefficient and Bartlett coefficient was calculated as 0.91 and 608.18, respectively. Single-factor solution was obtained with an eigenvalue of 5.44, representing 60.4% of the variance. Factor loadings of the items were between 0.66-0.80. Correlation coefficient of DSM-5 Depression Scale with BDI was found as r=0.88. Conclusion: The Turkish version of DSM-5 Depression Scale is reliable and valid. © 2017, Cukurova University, Faculty of Medicine. All rights reserved.

    Validity and reliability of the Turkish version of the DSM-5 Dissociative Symptoms Severity Scale–Child Form
    (Routledge, 2017) Yalın Sapmaz Ş.; Ergin D.; Şen Celasin N.; Özek Erkuran H.; Karaarslan D.; Öztekin S.; Uzel Tanrıverdi B.; Köroğlu E.; Aydemir Ö.
    The goal of this study was to assess the validity and reliability of the Turkish version of the DSM–5 (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition) Dissociative Symptoms Severity Scale–Child Form. The scale was prepared by translating and then back-translating the DSM–5 Dissociative Symptoms Severity Scale. The study groups included one group of 30 patients diagnosed with posttraumatic stress disorder who were treated in a child and adolescent psychiatry unit and another group of 83 healthy volunteers from middle and high schools in the community. For assessment, the Adolescent Dissociative Experiences Scale (ADES) was used in addition to the DSM–5 Dissociative Symptoms Severity Scale. Regarding the reliability of the DSM–5 Dissociative Symptoms Severity Scale, Cronbach’s alpha was.824 and item–total score correlation coefficients were between.464 and.648. The test–retest correlation coefficient was calculated to be r =.784. In terms of construct validity, one factor accounted for 45.2% of the variance. Furthermore, in terms of concurrent validity, the scale showed a high correlation with the ADES. In conclusion, the Turkish version of the DSM–5 Dissociative Symptoms Severity Scale–Child Form is a valid and reliable tool for both clinical practice and research. © 2017 Taylor & Francis Group, LLC.

    Reliability and validity study of the Turkish version of bipolar prodrome symptom scale
    (Turkish Association of Nervous and Mental Health, 2018) Aydemir Ö.; Öztekin S.; Akdeniz F.
    Objective: This study aimed to evaluate the reliability and validity of the Turkish version of Bipolar Prodrome Symptom Scale. Method: Thirty subjects with bipolar disorder and 122 healthy control subjects were enrolled in this study. All participants were 1st grade students of Celal Bayar University and were part of the study on the epidemiology of bipolar disorder. The Hypomania Checklist-32-Revised was used for concurrent validity. Statistical analysis, internal consistency coefficient, item-total score correlation coefficients, exploratory factor analysis, correlation with concurrent scale and ROC curve were calculated Results: The Bipolar Prodrome Symptom Scale was first translated into Turkish and than back-translated into English which led to the semantic harmony of the scale. Cronbach alpha coefficient was between 0.969 and 0.979, the item-total score correlations were between 0.767 and 0.929, and 0.725-0.890. The factor analysis for the severity subscale showed a one-factor solution representing 79% of the variance and the frequency subscale one-factor solution represented 72% of the solution. Correlation of Bipolar Prodrome Symptom Scale with Hypomania Checklist-32-Revised was r=0.513 and 0.530. The ROC analysis showed an area under the curve of 0.977 and 0.999. The scale discriminates well between the bipolar group and healthy control group. Conclusion: The Turkish version of the Bipolar Prodrome Symptom Scale developed for screening hypomania is reported to be reliable and valid. © 2018 Turkish Association of Nervous and Mental Health.

    Reliability and Validity of the Bipolar Prodrome Symptom Interview and Scale-Full Prospective in Its Turkish Translation
    (Mary Ann Liebert Inc., 2022) Sapmaz S.Y.; Ermiş Ç.; Çaklr B.; Öztekin S.; Guinart D.; Alşen Güney S.; Correll C.U.; Inal N.; Aydemir Ö.
    Editors' Note: The Editors would like to address issues related to the acceptance of this manuscript. The original manuscript referenced the study tool as the Bipolar Prodrome Symptom Interview Scale-Prospective (BPSS-P). After the manuscript's initial acceptance, the authors requested a revision of the tool name to Bipolar Prodrome Symptom Interview Scale-Full Perspective (BPSS-FP). When this request was made, the original acceptance was rescinded, and the authors were asked to formally revise and resubmit the manuscript with an explanation for the change. This revision and subsequent review led to the final acceptance of the manuscript. The authors have assured us that the tool used in the manuscript was the BPSS-FP (version 5) as opposed to abbreviated forms of this tool that are also used in research (e.g., Bipolar Prodrome Symptom Scale-Abbreviated Screen for Patients (BPSS-AS-P). Background: No scale exists to assess patients at-risk for bipolar disorder (BD) in Turkey. We aimed to assess the psychometric properties of the Turkish version of the Bipolar Prodrome Symptom Interview and Scale-Full Prospective (BPSS-FP). Method: Psychiatric service users aged 11-18 years old were interviewed using the BPSS-FP translated into Turkish and the Kiddie Schedule for Affective Disorders and Schizophrenia. Youth with major depressive disorder (MDD, n = 63), bipolar-spectrum disorder (n = 47), and healthy controls (n = 122) were included. Cronbach's alpha was calculated to assess internal consistency. The Young Mania Rating Scale (YMRS) and Children's Depression Rating Scale-Revised (CDRS-R) were administered to test convergent/discriminant validity. Discriminant validity was further tested using one-way ANOVA and "receiver operating characteristic"(ROC) curves. Inter-rater reliability was tested using correlation coefficients. Findings: Across 232 youth, Cronbach's alpha values were 0.932 for the BPSS-FP total score, 0.878 for the Mania Symptom Index, 0.887 for the Depression Symptom Index, and 0.797 for the General Symptom Index. Correlation coefficients for inter-rater reliability were high for the Mania Symptom Index (r = 0.989), Depression Symptom Index (r = 0.973), and General Symptom Index (r = 0.981). There were high correlations between the BPSS-FP Mania Symptom Index subscore and YMRS (r = 0.732), and the BPSS-FP Depression Symptom Index subscore and CDRS-R (r = 0.754), whereas cross-polarity correlations were non-significant. ROC analysis cut-off value was ≥21 for the BPSS-FP Mania Symptom Index between patients with BD and MDD (specificity = 85.7%, sensitivity = 78.7%). Conclusion: The Turkish version of the BPSS-FP has good psychometric properties and can be used in research. Longitudinal studies are needed to confirm the predictive value of the BPSS-FP. © Copyright 2022, Mary Ann Liebert, Inc., publishers 2022.
