Cross-cultural validation of the Korean male version of athletes sleep behavior questionnaire

Abstract

In male athletes, sleep plays an important role in recovery and the improvement of physical abilities through high-intensity training. Unfortunately, no appropriate questionnaire is currently available to assess sleep problems in male Korean athletes. Therefore, this study translated and cross-culturally validated the Athlete Sleep Behavior Questionnaire (ASBQ) for male Korean athletes. This study employed a conceptual review, comprising translation preparation, review, and preliminary investigation, and a statistical review, comprising the test-retest method, test-retest reliability, and internal consistency analysis. Content equivalence between the original ASBQ text and the Korean version was secured, and test-retest reliability and internal consistency were acceptable. Acceptable levels of comprehension were observed for the translated questions. The dependent t-test analysis showed no significant differences between any of the questions. A verification of the stability of the Korean male version of the ASBQ using the test-retest method at 2-week intervals showed an acceptable level of reliability (intraclass correlation coefficient = 0.78, r = 0.77, typical measurement error = 2.5, coefficient of variation = 7.6%). Lastly, the internal consistency reliability test revealed a Cronbach’s α of 0.87 at the 95% confidence level. The Korean male version of the ASBQ showed content equivalence and reliability with the original version. It can be used as a tool to analyze the sleeping behavior of Korean male athletes and provide customized training schedules.
