The influence of childhood trauma on social media-induced secondary traumatic stress among college students: the chain mediating effect of self-compassion and resilience

<b>Background:</b> Studies have shown that media exposure to critical public events can lead to secondary traumatic stress (STS). Personal trauma history, self-compassion and resilience are important factors influencing STS in healthy professionals. However, whether these variables are associated with social media-induced STS in college students and the underlying mechanisms remain unclear. The purpose of this study was to explore the complex relationship linking childhood trauma to social media-induced STS in a large sample of college students.<b>Methods:</b> A total of 1151 Chinese college students from Chengdu, Sichuan Province of China completed a web-based cross-sectional survey, which included standard assessments of childhood trauma, self-compassion, resilience and social media-induced STS, as well as sociodemographic questionnaires. The chain mediation model was tested using the PROCESS macro programme in SPSS software.<b>Results:</b> There was a moderate correlation between childhood trauma and social media-induced STS (<i>r = </i>0.34, <i>p </i>< .001). This association was significantly mediated by self-compassion (indirect effect [95% CI] = 0.14[0.11, 0.17]) and resilience (indirect effect = 0.03[0.01, 0.04]), respectively. Further, a chained mediating effect was observed with self-compassion and resilience consecutively mediated the relationship between childhood trauma and social media-induced STS (indirect effect = 0.02[0.01, 0.03]). These results persisted after sociodemographic characteristics were included as controlling variables.<b>Conclusions:</b> Early life trauma impacts STS induced by exposure to traumatic materials on social media through self-compassion and resilience among Chinese college students. Psychological interventions targeting self-compassion and resilience can be implemented to reduce the risk of STS, especially in vulnerable individuals.
