Abstract
Background: Tayside children's sleep questionnaire (TCSQ) is a simple tool for screening the Disorders of Initiating and Maintaining Sleep among children aged between one and five years. In this study, we aimed to translate TCSQ into Persian and evaluate the validity and reliability of TCSQ among Persian speakers.Methods: A cross-sectional study was conducted among 311 children aged 1-5 years in Isfahan. After permission, the forward-backward translation method is used to develop the Persian version. Finally, 311 children participated in this survey, and 30 were repeated for a second time. Google Form, SPSS16, and STATA14 were used for data collection, descriptive statics, and factor analysis. BEARS questionnaire is used for convergent validity. Three expert opinions were used for content validity.Results: In this study, 404 mothers of children in Isfahan volunteered to participate in the survey, of which 311 remained. The mean and standard deviation age of their children was 3.47±1.91 years. Cronbach Alpha of the Persian version of TCSQ was 0.76 CI (0.78-0.66). The intra-class correlation coefficient was 0.67 CI (0.60-0.74). The content validity index was 0.88, and three factors (Disturbance, nighttime, parents) with a specific value greater than 0.4 is determined by factor analysis.Conclusions: The current study results indicate that TCSQ has good reliability and validity among Persian speakers.
