Abstract

Objective: The aim of this study was to have a linguistic validation of the Sleep Disturbance Scale for Children (SDSC) in Iranian children with Persian language. Methods: The study included a randomly selected sample of children, aged 6-15. years, from three primary and secondary schools located in Isfahan City, Iran. Following the forward-backward translation method, parents completed the SDSC as well as the Pediatric Quality of Life Inventory (PedsQL™). Reliability (Cronbach's α) and convergent validity (item-subscale and subscale-total correlations) were assessed. The association of SDSC scores with PedsQL scores was evaluated for construct validity. Results: One hundred children were studied; mean age, 9.36. ±. 2.58. years, 68 girls. Scale Cronbach's α was 0.82, ranging from 0.40 for 'disorder of arousal' to 0.86 for 'sleep hyperhidrosis' subscales. Convergent validity was acceptable according to the corrected item-subscale correlations (r=0.22-0.76) and corrected subscale-total correlations (r=0.30-0.50). The SDSC total score as well as its subscales, except the 'disorder of arousal', were associated with the total PedsQL score and its factors (r=-0.20 to -0.64). Conclusion: The overall psychometric properties of the Persian version of the SDSC seem to be appropriate in Iranian children. © 2014 Elsevier B.V.
