Development and field test of the child and adolescent sleep checklist for parents of community junior high school students

Aim Children and adolescents get fewer than the recommended hours of sleep. The Child and Adolescent Sleep Checklist for parents (CASC-P) was designed to identify sleep habits and screen for sleep problems in junior high school students in Japan. This study aimed to validate the Japanese version of the CASC-P for junior high school students and determine its internal consistency. Methods We used confirmatory factor analysis (CFA) and Cronbach's α to validate the scale and examine reliability. The analysis involved 218 parents of students aged 12–15 years. Results Cronbach's α for the overall scale was 0.771. The prevalence of sleep problems was 15.6%. Factorial construct validity was assessed using the four-factor model used in the original CASC-P. Almost all items loaded meaningfully on their designated factors, and standardized factor-loading values ranged from 0.278 to 0.878 (except for items 1, 2, 9, 16, and 21). Conclusion : The CASC-P is a suitable questionnaire for assessing parents’ perspectives on adolescent sleep behavior.
