Athlete Sleep Screening Questionnaire in Japanese: Adaptation and Validation Study

Area of Science:

• Sports Medicine
• Sleep Science
• Psychometrics

Background:

• Limited general screening methods for athletes' sleep health.
• Sleep disorders are prevalent among athletes across all levels.
• The need for validated screening tools in specific populations.

Purpose of the Study:

• To analyze the reliability and validity of the Japanese version of the Athlete Sleep Screening Questionnaire.
• To assess the internal consistency and test-retest reliability.
• To explore potential differences in sleep difficulty based on sport type and athletic level.

Main Methods:

• 111 female collegiate athletes completed test-retest.
• Reliability assessed using Cronbach's alpha and intraclass correlation coefficients.
• Comparison between team and individual sport athletes.

Main Results:

• 38.7% of athletes reported moderate to severe sleep difficulties.
• Cronbach's alpha values were .34 (test) and .44 (retest).
• Intraclass correlation indicated sufficient test-retest validity; sleep issues during travel correlated with overall sleep difficulty.

Conclusions:

• The Japanese Athlete Sleep Screening Questionnaire demonstrates adequate test-retest validity.
• Poor internal consistency suggests limitations for widespread use without modification.
• Further research is recommended to culturally adapt the questionnaire for Japanese athletes.
