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 assessment 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 be-tween 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.
