Path analysis of mediating effect of perceived stress affecting impact of event in rehabilitation patients with traumatic injury / 中国康复理论与实践

ABSTRACT

ObjectiveTo explore the effect of perceived stress on the impact of event in rehabilitation patients with traumatic injury, and the mediating role of difficulties in emotion regulation, rumination and sleep. MethodsFrom March, 2022 to March, 2023, using the convenient sampling method, a questionnaire survey was conducted on 192 rehabilitation patients with traumatic injury from Southwest Hospital, Xinqiao Hospital and Daping Hospital. Assessment tools included Perceived Stress Scale, Difficulties in Emotion Regulation Scale, Brief Ruminative Response Scale, Self-Rating Scale of Sleep, and Impact of Event Scale-revised. ResultsPerceived stress, difficulties in emotion regulation, rumination, sleep and the impact of event were correlated with each other in rehabilitation patients with traumatic injury (r = 0.447~0.684, P < 0.01). Perceived stress significant positively predicted the impact of event (β = 0.49, P < 0.001), as well as difficulties in emotion (β = 0.70, P < 0.001), rumination (β = 0.21, P < 0.05) and sleep (β = 0.29, P < 0.001). The direct effect of perceived stress on the impact of event was not significant, but it affected the impact of event through seven mediation paths, among which the independent mediation effect size of difficulties in emotion regulation, rumination and sleep accounted for 24.41%, 11.91% and 24.82%, respectively; the chain mediation effect size of difficulties in emotion regulation and rumination accounted for 13.88%, the chain mediation effect size of difficulties in emotion regulation and sleep accounted for 18.08%, the chain mediation effect size of rumination and sleep accounted for 3.17%, and the chain mediation effect size of difficulties in emotion regulation, meditation and sleep accounted for 3.70%. ConclusionPerceived stress affected the impact of event in rehabilitation patients with traumatic injury through the independent mediation and chain mediation of difficulties in emotion regulation, rumination and sleep.
