Explaining the Relation Between Perceived Social Support and Psychological Well-Being Among Chinese Nursing Students: A Serial Multiple Mediator Model Involving Integrative Self-Knowledge and Self-Integrity.

Background: Addressing numerous calls for understanding the theoretical mechanisms that explain the relationship between perceived social support and psychological well-being to enhance nursing students' mental health. Aims: This study focused on how integrative self-knowledge and self-integrity mediate the relationship between perceived social support and psychological well-being. Methods: The Structural Equation Model (SEM) was used to estimate the mediation effects on the relationship between perceived social support and psychological well-being among 487 undergraduate nursing students. To examine the directionality of effects, the present study also tested the reverse serial mediation model. Multi-group SEM (MGSEM) was used to test gender differences in the mediation model. Results: Integrative self-knowledge and self-integrity, in sequence, mediated the association between perceived social support and psychological well-being among nursing students. In addition, there was no gender difference in these associations. Conclusions: Improving nursing students' perceived social support, integrative self-knowledge, and self-integrity is beneficial for promoting their mental health. [ABSTRACT FROM AUTHOR]
