Research in Positive Psychology has indicated a correlation between Psychological Capital (PsyCap) and Mental health (MH). However, the specific contribution of Perceived Social Support (PSS) in the connection between PsyCap and MH, particularly within higher education, remains uninvestigated. This study investigated how PSS could mediate the effect of PsyCap on students' MH using a cross-sectional research design. The sample encompassed 443 undergraduate graduate students at Huazhong University of Science and Technology in Wuhan, China. Results from Partial Least Squares Structural Equation Modeling (PLS-SEM) showed that both PsyCap (β = 0.815, t = 31.074, p < 0.000) and PSS (β = 0.405, t = 28.051, p < 0.000) have a positive impact on students' MH. Additionally, PSS was identified as a significant mediator in relation to students' MH (b = 0.080, t = 2.319, p < 0.020). This study emphasizes the importance of developing these factors in educational and support programs to enhance students' well-being. Moreover, the results offer significant conceptual and practical insights for higher education faculty, psychologists, and curriculum designers.
