Abstract
We examined the effect of sleep and resilience on stress responses in female Japanese university students during the COVID-19 pandemic. Sleep was measured using the Japanese version of the Pittsburgh Sleep Quality Index (PSQI-J), stress response was evaluated using the Stress Response Scale-18 (SRS-18), and resilience using the Resilience Scale for Students (RS-S). Multiple regression analysis showed that approximately 40% of the SRS-18 score could be explained by PSQI-J score and RS-S score. Subjective sleep quality, daytime dysfunction, and global score of PSQI-J had direct influences on SRS-18.
