Athlete Sleep Behavior Questionnaire - Turkish Version: Study of Validity and Reliability

Abstract

Objective: Athlete sleep behavior questionnaire (ASBQ) is a new, valid and reliable questionnaire for evaluating the sleep behaviors of elite athletes. The main objective of the current study was to provide evidence for the validity and reliability of the Turkish version of the ASBQ (ASBQ-TR). Materials and Methods: Ninety-seven athletes and eighty-three non-athletes were included in the current study and asked to complete the 18-item ASBQ-TR. A sub-group of athletes (n=50) completed the ASBQ-TR twice, 7 days apart. The ASBQ was translated into English twice and then back-translated to Turkish after the permission of the author was received. Test-retest reliability and internal consistency were performed via intraclass correlation coefficient (ICC) and Cronbach's alpha, respectively. Results: There was a significant difference between the athlete and non-athlete groups in ASBQ-TR total score (38.4 and 36.2 respectively, p<0.05). Test-retest reliability of the questionnaire was acceptable (ICC=0.85). The factor loadings of ASBQ-TR were between 0.41 and 0.82. One of the 18-items of the questionnaire was removed due to the factor loading (below 0.40). Conclusion: The ASBQ-TR is a 17-item valid and reliable tool that can be used to identify sleep challenges that athletes face. The ASBQ-TR can be used as a practical tool for researchers and coaches evaluating the sleep behaviors of elite athletes. This tool may also be used to examine the sleep behavior differences among sports with different recovery needs and training loads.
