Injury prevention and health promotion among elite athletes are crucial to athletic success. Risk management requires the understanding and adjustment of physical, environmental, and psychological factors. Sleep status can be one of the essential factors for maintaining good health and preventing injury. The Athlete Sleep Screening Questionnaire (ASSQ) is expected to be an international standard for evaluating the sleep status of elite athletes. The 16 items ASSQ assess several sleep-related factors, including sleep difficulty, sleep-disordered breathing such as snoring and apnea, sleep and psychosomatic functioning during expeditions, chronotype, napping, caffeine intake, and electronic device use.
A total of 158 male college soccer players responded the ASSQ-J and the Japanese version of the Pittsburgh Sleep Quality Index (PSQI-J). A factor analysis was conducted to validate the factor structure of the ASSQ-J. The internal consistency of ASSQ-J is assessed for validation. Pearson’s correlation coefficients and kappa statistic were calculated to determine if the ASSQ-J was significantly associated with PSQI-J respectively.
Regarding the ASSQ-J-SDS, 22.4% (35 of 156) of the subjects in this study scored 8 or higher (moderate or higher), which was almost consistent with the results of a previous study on college athletes. It is clear that some Japanese male collegiate soccer players have sleep problems, as same as collegiate athletes around the world. Further research is needed for the validation of the ASSQ-J, the sleep status in a wider range of ages and sports are also investigated.
