Introjected regulation and academic burnout: A moderated mediation model of social comparison and distress overtolerance.

The primary purpose of this study is to examine the mediation effect of Contrastive Upward Comparison (CUC) on the relationship between introjected regulation and exhaustion (i.e., introjected regulation-CUC-exhaustion). It is also aimed to examine the moderation effect of distress overtolerance on this mediated relationship. In order to resolve the uncertainty about the causality of cross-sectional studies, this study worked on the relationship among the variables by setting an alternative model (i.e., CUC-introjected regulation - exhaustion). The participants were 167 (females, 70.7%) undergraduate and graduate students in South Korea. The results of this study indicated that introjected regulation showed indirect and significant effect on exhaustion via CUC. However, in the alternative model, the indirect effect of introjected regulation in the relationship between CUC and exhaustion was not significant. Furthermore, high distress overtolerance buffered the relationship between introjected regulation and CUC, while it strengthened the association of CUC and exhaustion. Lastly, the results of moderated mediation suggested that students with higher distress overtolerance, experienced more CUC, and emotional exhaustion. The implications and limitations were also discussed.
