    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-Meğer-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. © 2017, Cukurova University, Faculty of Medicine. All rights reserved.

    Objective: In this study we evaluated the reliability and validity of the Turkish version of DSM-5 Psychosis Scale developed in order to evaluate severity of psychosis in adult patients. Methods: This study was carried out with patients who met the diagnostic criteria for any psychotic disorder according to DSM-5 criteria and who are undergoing treatment in the inpatient and outpatient wards of Psychiatry Department of Celal Bayar University Medical School. Except for psychotic disorders patients with any mental or physical disease were excluded. A total of 49 patients (40 patients with schizophrenia, six patients with not otherwise specified psychotic disorder, three patients with schizoaffective disorder) were included in the study. One hundred and one volunteers without any mental or physical disease were included as the healthy control group. Reliability analysis was based on internal consistency and item-total score correlation. Validity analysis was based on exploratory factor analysis, comparison of mean scores of the patient and healthy control groups and ROC analysis. Results: The mean age of the study group was 26.0±10.3 years and 52.7% of the sample group (n=79) were female. Sixty-nine point three percent of the study group were college graduates, 8% primary school graduates, 19.3% is also high school graduates. Mean disease duration was 17.1±9.7 years in the psychotic disorder group. The internal consistency of the Psychosis Scale was 0.91 and, item-total correlation coefficients of the Psychosis Scale were between 0.25 and 0.82. In the factor analysis, for sample adequacy Kaiser- Meier-Olkin (KMO) coefficient was found as 0.81 and Bartlett coefficient as 1.03. Single-factor solution was obtained and the eigenvalue is 5.12, representing 64.0% of the total variance. Factor loadings of the items of the scale were between 0.33 and 0.88. The mean of score was 11.00±5.20 in patient group while it was calculated as 0.21±1.21 in control group. The area under the curve was calculated as 0.98 in the ROC analysis. Conclusion: These results indicate that the Turkish version of Psychosis Scale is reliable and valid. © 2017, Cukurova University, Faculty of Medicine. All rights reserved.

    Objective: The purpose of the present study was to investigate the validity and reliability of the Turkish form of the Clinician Rated Severity of Autism Spectrum and Social Communication Disorders Scale. The scale was originally developed to measure the severity of autism spectrum and social communication disorders regarding the DSM-5 criteria. Methods: The study was conducted in the Department of Psychiatry at Celal Bayar University Hospital. The participants were in- or out-patients diagnosed with any psychotic disorders according to DSM-5. The exclusion criteria were comorbidity of other psychiatric disorders and/or physical diseases. The study was carried out with a total of 49 patients who were diagnosed with schizophrenia (n=40), schizoaffective disorder (n=3), and not otherwise specified psychotic disorder (n=3). One hundred and one volunteers without any mental or physical disease were also included to represent the healthy control. Reliability analysis was performed to examine the internal consistency of the Turkish version of the scale. Additionally, item-total correlations were reported. In validity analyses, comparison of the total score of the scale in the patient and control groups was evaluated for the discriminative validity. ROC analysis was also performed. Results: 52.7% of the sample were male (n=79). 69.3% of them were graduated from university (n=104), 19.3% from high school (n=29), and 8% from elementary school (n=12). The mean age of the study group was 26.3±10.3 years. Disease duration of psychotic disorder group was 18,29±6.43 years. The internal consistency of the Autism Spectrum and Social Communication Disorder Scale was 0.81. Furthermore, item-total correlations revealed that all items in the scale contributed to the consistency of scores with item-total correlations approaching 0.70. The mean score of the scale in the patient group on the scale was 1.42 whereas the mean score of the healthy group was 0.0. The t-test analysis indicated that there was a statistically significant difference between the sample group and the healthy group in their scores on the scale. In the ROC analysis, the area under the curve was 0.84. Conclusion: Results demonstrated that the Turkish version of Autism Spectrum and Social Communication Disorder Scale was a valid and reliable instrument which may serve as useful in guiding future research that aims to understand autism spectrum and social communication disorder. © 2017, Cukurova University, Faculty of Medicine.
