Background In recent years, with the acceleration of the pace of modern life and the increase of life pressure, the prevalence of poor sleep quality has risen substantially among young people. Insufficient sleep and insomnia have emerged as a serious public issue in modern society. This study aimed to investigate the effect of perceived stress on sleep quality, with particular focus on the mediating roles of anxiety and sleep procrastination in the stress-sleep quality relationship. Methods A total of 2,486 Chinese graduate students participated in the questionnaire survey, which used the Perceived Stress Scale, the Bedtime Procrastination Scale, the Pittsburgh sleep quality index, and the Self-rating Anxiety Scale. Descriptive statistics, correlation analysis, and the bootstrap method were utilized for data analysis. Results The findings revealed a 37.8% prevalence of sleep disturbances among the participants. Notably, the mediating effects of anxiety and sleep procrastination in the association between perceived stress and sleep quality were statistically significant ( p < 0.05). Conclusion The results showed that higher perceived stress was positively associated with greater anxiety, which further contributed to sleep procrastination, and ultimately correlated with poorer sleep quality.
