Abstract: Objective: To analyze the influencing factors of kinesiophobia in patients with pain due to accidental trauma, and then to further explore the impact path of factors, so as to provide reference for clinical intervention. Methods: Emergency trauma patients were selected by convenience sampling method from February to March in 2022 in a tertiary grade A hospital in Changsha, the subjects were investigated with general condition questionnaire, pain numerical rating scale, pain catastrophe scale, social support scale, and Tampa scale for kinesiophobia. Generalized linear model was used to analyze the influencing factors and the structural equation modeling was used to analyze the path. Results: The pain score of 440 trauma patients was 3.50(2.0, 5.0), the score of kinesiophobia was 44.00(38.0, 48.8). The influencing factors of kinesiophobia were education level, occupation type, catastrophic pain, social support and pain degree. Path analysis result showed that catastrophic pain and social support directly predict the level of kinesiophobia, and social support and pain severity influence the level of kinesiophobia by the mediating of catastrophic pain. Conclusion: The incidence of kinesiophobia in patients with accidental trauma is high, medical staff should intervene pain as soon as possible, so as to reduce the level of kinesiophobia by alleviating the degree of catastrophic pain.
