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

Background: 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.

Methods: 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.

Results: There was a moderate correlation between childhood trauma and social media-induced STS (r = 0.34, p < .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.

Conclusions: 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.

HIGHLIGHTS

• Exposure to traumatic information through social media can lead to secondary traumatic stress.
• Childhood trauma is related to social media-induced secondary traumatic stress.
• Self-compassion and resilience sequentially mediate this relationship between childhood trauma and social media-induced secondary traumatic stress.
