Translation, cultural adaptation, and psychometric validation of the Simplified Chinese Athlete Sleep Behavior Questionnaire (ASBQ-CN) in Chinese athletes

Objective: To translate, adapt, and validate the Simplified Chinese Athlete Sleep Behavior Questionnaire (ASBQ-CN) for both adolescent and adult athletes. Design: Cross-sectional psychometric evaluation. Methods: A total of 480 Chinese athletes (19.9 ± 4.4 years) and 408 non-athletes (23.3 ± 3.9 years, for discriminant validity evaluation) were recruited. Psychometric testing included internal consistency, test–retest reliability, content validity, exploratory and confirmatory factor analyses, and convergent and discriminant validity. For robust factor analysis of ordinal data, parallel analysis with polychoric correlations and ordinary least squares estimations were choose. Results: The ASBQ-CN demonstrated acceptable internal consistency (Cronbach’s αtotal of 0.76) and test–retest reliability (intraclass correlation coefficient of 0.78). The standard error of measurement and minimal detectable change were 3.13 and 8.67, respectively. Content validity achieving indices of 1.0 at toth item- and scale-level. Factor analyses supported a four-factor structure with acceptable model fit indices (comparative fit index = 0.95, Tucker Lewis index = 0.94, root mean square error of approximation = 0.06, and standardized root mean square residual = 0.09). Convergent validity was confirmed by moderate correlations with the Pittsburgh Sleep Quality Index (rtotal = 0.44) and Sleep Hygiene Index (rtotal = 0.50). Although total ASBQ-CN scores did not significantly differ between athletes and non-athletes, significant item-level differences were identified (p
