This study explores the interrelationship between experiential avoidance, cognitive fusion, and rumination and investigates the predictive roles of experiential avoidance and cognitive fusion on rumination. Data were collected from 600 university students using the Ruminative Responses Scale, Cognitive Fusion Questionnaire, and Acceptance and Action Questionnaire-II. Correlation analysis was employed to explore the relationships among the three factors. Mediation analysis was used to investigate the mediating role of cognitive fusion between experiential avoidance and rumination, and random forest analysis was applied to test the predictive roles of experiential avoidance and cognitive fusion on rumination. Positive correlations were found among experiential avoidance, cognitive fusion, and rumination. Cognitive fusion played a partial mediating role in the link between experiential avoidance and rumination. The fifth and third items of experiential avoidance were the most critical predictors of rumination, with a prediction performance R2 of 0.678 in the test set. Cognitive fusion partially mediates the connection between experiential avoidance and rumination among university students, and the model demonstrates good predictive performance for rumination. Our research contributes to a better understanding of the interrelationships among experiential avoidance, cognitive fusion, and rumination in university students.
