Translation, Adaptation, and Validation of the Athlete Sleep Behavior Questionnaire for Persian-Speaking Athletes

The Athlete Sleep Behavior Questionnaire (ASBQ) is a valuable tool for assessing sleep-related issues in athletes. However, its psychometric properties in specific populations require thorough investigation. To examine the psychometric properties of the ASBQ in a sample of Iranian athletes and nonathletes. Cohort study (diagnosis); Level of evidence, 3. A cross-sectional study was conducted with 978 participants (52% athletes, 48% nonathletes). Participants with a sleep disorder were excluded from the study. Data were collected on sociodemographic characteristics and participants were administered the ASBQ. Confirmatory factor analysis (CFA) was performed to evaluate the model fit. Cronbach alpha was used to assess internal consistency. CFA results indicated acceptable model fit, with a comparative fit index of 0.91 and root mean square error of approximation of 0.075. Although some fit indices showed slight deviations, overall the factorial structure was supported. The Cronbach alpha for the overall scale was 0.876, demonstrating good internal consistency. Subscale reliabilities were also acceptable (behavioral: 0.720; environmental: 0.694; sports: 0.695). The findings of this study suggest that the Persian version of the ASBQ exhibits acceptable psychometric properties in this Iranian sample. These results support the use of the ASBQ for assessing sleep-related issues in Iranian athletes and provide valuable information for future research and interventions.
