Purpose: The current study examined the association between moral elevation and college students’ sense of meaning of life, along with the potential mediating effects of gratitude and perceived social support on this relationship.
Methods: Using the convenience sampling method, the Moral Elevation Scale, the Sense of Meaning of Life Questionnaire, the Gratitude Questionnaire, and the Multidimensional Scale of Perceived Social Support were used to conduct questionnaire surveys on 1088 college students (M_age=19.59 years, SD=1.46). SPSS25.0 data statistics software was used to analyze the data, and the PROCESS macro for SPSS was used to conduct the mediation effect test.
Results: (1) Moral elevation was significantly and positively associated with college students’ sense of meaning of life (β = 0.43,p < 0.001). (2) Both gratitude and perceived social support partially mediated the relation between moral elevation and sense of meaning of life. The indirect effect of moral elevation on sense of meaning of life via gratitude was 0.11 (95% CI = [0.0709, 0.1453]), and the mediating effect accounted for 52.71%. The indirect effect of moral elevation on sense of meaning of life via perceived social support was 0.06 (95% CI = [0.0385, 0.0863]), and the mediating effect accounted for 29.41%. (3) Gratitude and perceived social support sequentially mediated the association between moral elevation and sense of meaning of life, the indirect effect through gratitude and perceived social support was 0.04 (95% CI = [0.0237, 0.0512]) and accounted for 17.88%.
Conclusion: This study revealed the chain mediating roles of gratitude and perceived social support in the relation between moral elevation and sense of meaning of life for Chinese college students, which is of great theoretical and practical significance for the formation of a positive sense of meaning of life and the cultivation of moral elevation among college students.
