Abstract
INTRODUCTION: This study aimed to assess the validity and reliability of Turkish version of DSM-5 Level 2 Sleep Disorders Scale. METHOD: The scale was prepared by translation and back translation of DSM-5 Level 2 Sleep Disorders Scale. Study groups consisted of a clinical sample that contained cases that had sleep related problems and treated in a child and adolescent psychiatry unit and also a community sample. In the assessment process, child and parent forms of DSM-5 Level 2 Sleep Disorders Scale and also Children's Sleep Habits Questionnaire-Turkish version (CSHQ) and Pittsburgh Sleep Quality Index (PSQI) were used. As for reliability analyses, internal consistency coefficient and item-total score correlation analysis, test-retest reliability; and for validity analyses, explanatory factor analysis and for concurrent validity, correlation analyses with Children's Sleep Habits Questionnaire-Turkish version (CSHQ) and Pittsburgh Sleep Quality Index (PSQI) were made. RESULTS: In reliability analyses, Cronbach's alpha internal consistency coefficient values were found to be very highly reliable regarding child and parent forms. Item-total score correlation coefficients were high for child form while medium and high for parent form; indicating a statistical significance. As for construct validity, two factors were maintained that would count for 74.1% of the variance in child form and 66.9% of the variance in parent form. It was seen that positive and negative statements weighed on two different factors. As for concurrent validity, child and parent form of the scale showed significant correlation with Children's Sleep Habits Questionnaire-Turkish version (CSHQ) and Pittsburgh Sleep Quality Index (PSQI). CONCLUSION: It was found that Turkish version of DSM-5 Level 2 Sleep Disorders Scale could be utilized as a valid and reliable tool both in clinical practice and for research purposes.
