Objective: This study, demonstrate the reliability and validity of the Turkish form of DSM-5 Sleep Disorder Scale which improved according to DSM-5 criteria to measure the intensity of sleep disorder. Methods: This study were carried out with patients fulfilling the diagnosis of any sleep disorder according to DSM-5 criteria and who are undergoing treatment in Celal Bayar University Hospital sleep medicine inpatient or outpatient clinic. Patients with any mental or physical disease except for anxiety disorders were excluded. As a result, 50 patients with sleep disorder were included in the study and diagnoses of OSAS in 41 patients, primer insomnia in five patients, parasomnia in three patients and narcolepsia in one patient were made. Without any mental or physical disease in 50 volunteers formed the control group. Beside the DSM-5 Sleep Disorder Scale, the most widely used scale for sleep disorders, Pittsburgh Sleep Disorder Index (PSQI), was used for validation. Internal consistency coefficient and item-total score correlation analysis for reliability analysis; factor analysis and correlation analysis with the PSQI, and ROC analysis for discrimination between the sleep disorder and healthy control group for validity were performed. Results: The mean age of the study group was 39.3±15.8 years and 47.0% of the sample group (n=47) were female. 55.0% of the group were college graduates, 22.0% primary school graduates, 18.0% were high school graduates. Disease duration of sleep disorder group was 16.8±12.6 years. The internal consistency of the DSM-5 Sleep Disorder Scale was 0.91 and, item-total score correlation coefficients of the DSM-5 Sleep Disorder Scale were between 0.61 and 0.81. For the factor analysis, the sample adequacy of DSM-5 Sleep Disorder Scale was determined with Kaiser- Meier-Olkin (KMO) analysis where the coefficient was 0.91 and Bartlett analysis where chi-square was 1.54. Single-factor solution was obtained and the eigenvalue is 5.07 representing 63.4% of the total variance. Factor loadings of the items of the scale were between 0.69-0.87. Coefficient of correlation analysis with PSQI was calculated as r=0.727. In the ROC analysis, the area under the curve was obtained as 0.76. Conclusion: These findings have been shown that the DSM-5 Sleep Disorder Scale is reliable and valid for Turkish. [Anadolu Psikiyatri Derg 2017; 18(0.200): 79-84]
