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 in cluded 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 corre-lation 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, item-total correlation coefficients of the DSM-5 Mania Scale were between 0.67 and 0.85. In the explanatory factor ana-lysis, 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 vari-ance. Factor loadings of the items were between 0.77-0.91. Significant and high levels of correlation were deter-mined 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. [Anadolu Psikiyatri Derg 2017; 18(0.200): 73-78]
