    Reliability and validity of Turkish Form of DSM-5 Mania Scale
    Öztekin, S; Alçi, D; Aydemir, Ö
    Objective: This study aimed to demonstrate the reliability and validity of the Turkish form of DSM-5 Mania Scale which was developed according to DSM-5 criteria to measure the severity of mania. Methods: This study was conducted with 50 patients who meet the diagnostic criteria of bipolar disorders according to DSM-5 criteria who are within manic or euthymic episode. The patients were under treatment at inpatient and outpatient clinics of Psychiatry Department of Celal Bayar University, Medicine Faculty. Patients with any mental or physical disease except bipolar disorders were excluded. Sixty-three volunteers without any mental or physical disease were included as healthy control group. Beside DSM-5 Mania Scale the most widely used scale Young Mania Rating Scale (YMRS) 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 ages of the bipolar disorders group (n=50) and healthy control group (n=63) were respectively 30.9 +/- 13.6 and 22.4 +/- 5.8. 53.7% of the sample group (n=58) were female. Disease duration of bipolar disorder group was 7.2 +/- 7.9 years. The internal consistency of the DSM-5 Mania Scale was 0.91 and, itemtotal correlation coefficients of the DSM-5 Mania Scale were between 0.67 and 0.85. In the explanatory factor analysis, for sample adequacy Kaiser- Meier-Olkin (KMO) coefficient was calculated as 0.85 and Bartlett coefficient was 389.51. Single-factor solution was obtained and the eigenvalue was 3.69, explaining 73.8% of the total variance. Factor loadings of the items were between 0.77-0.91. Significant and high levels of correlation were determined between YMRS and DSM-5 Mania Scale (r=0.78). Conclusion: These findings have been shown that the DSM-5 Mania Scale is reliable and valid for Turkish.

    Çöldur, EÖ; Öztekin, S; Aydemir, Ö
    Objective: The purpose of the present study was to investigate the reliability and validity of the Turkish Form of Level 2 Anger Scale. The scale was originally developed to measure the severity of anger regarding the DSM-5 criteria. Methods: This study was conducted in the Department of Psychiatry in Celal Bayar University Hospital. The participants were in- or out-patients diagnosed with any psychotic disorders according to the DSM-5. The exclusion criteria were comorbidity of other psychiatric disorders and/or physical diseases. The participants were 49 patients who were diagnosed with schizophrenia (n=40), schizoaffective disorder (n=3), and not otherwise specified psychotic disorder (n=6). One hundred and one volunteers without any mental or physical disease were also included to represent the healthy control. In the assesment beside Level 2 Anger Scale, 18-item Brief Psychiatric Rating Scale was used. In reliability analysis internal consistency coefficient and item-total correlation analysis were performed; for validity analysis exploratory factor analysis was performed. In concurrent validity correlation analyses between Level 2 Anger Scale and BPRS tension, hostility, uncooperativeness, and elated mood subscales were computed. In order to discriminate between the psychosis and the control group, group means of Anger Scale were compared with t-test. Results: The mean age of the study group was 26.0 +/- 10.3 and 52.7% of the sample group were female (n=79). 69.3% of them were graduated from university (n=104), 19.3% from high school (n=29), and 8% from elementary school. Disease duration of psychotic disorder group was 17.1 +/- 9.7 years. The internal consistency of the Level 2 Anger Scale was 0.91 and, item-total correlation coefficients were between 0.74-0.83. For the exploratory factor analysis of sample adequacy of Level 2 Anger Scale Kaiser- Meger-Olkin (KMO) coefficients 0.81 and Bartlett coefficient 1.03 was found. Single-factor solution was obtained and the eigenvalue is 3.79, representing 75.80 % of the total variance. Factor loadings of the items of the scale were between 0.83-0.90. The mean of score was 5.09 +/- 0.72 in the psychosis group while it was calculated as 3.65 +/- 0.36 in the control group. There was a statistically significant difference between the groups. There were moderate to high correlations between Level 2 Anger Scale and BPRS tension, hostility, uncooperativeness, and elated mood. Conclusion: Results demonstrated that the Turkish version of Level 2 Anger Scale is a valid and reliable.

    Relationship of levetiracetam and obsessive-compulsive disorder: a case report
    Çökmüs, FP; Asçibasi, K; Öztekin, S; Demet, MM
    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.
