Background: Sub-health can have an impact on the physical condition of the young adults, and this study aimed to investigate the influencing factors of sub-health related to the Big Five personality in Chinese young adults.
Methods: A multi-stage random sampling method was used to survey the Chinese young adults. A moderated mediation analysis was conducted to investigate how sleep quality and family health influenced the relationship between diverse personalities and sub-health in young adults.
Results: A total of 6165 young adults were included in this study. The results of the mediation analysis indicated that sleep quality partially mediated the relationship between neurotic, extraversion, agreeableness, and conscientiousness of young adults and sub-health. Family health played a moderating role between the sleep quality and agreeableness of young adults.
Limitations: The cross-sectional study limits conclusions about causal relationships between factors.
Conclusion: Family health and sleep quality can influence sub-health in Chinese young adults with different personality traits.
