Abstract:
Objective:To explore the mediating effect of self-efficacy and fatigue between depression and cognitive function in patients with spinal cord injury.Methods:General information questionnaire, Hamilton Depression Scale, Montreal Cognitive Scale, Rehabilitation Exercise Self-Efficacy Scale, Fatigue Revised Scale were used to investigate 256 cases of spinal cord injury patients from December 2018 to August 2020. The deviation-corrected percentile Bootstrap method was used to test the chain mediating effect of rehabilitation exercise self-efficacy and fatigue on depression and cognitive function.Results:Correlation analysis showed that depression was negatively correlated with cognitive function ( r=-0.146, P<0.01), self-efficacy of rehabilitation exercise ( r=-0.115, P<0.01), and positively correlated with fatigue ( r=0.317, P<0.01), self-efficacy of rehabilitation exercise was positively correlated with cognitive function ( r=0.903, P<0.01), and negatively correlated with fatigue ( r=-0.889, P<0.01), and fatigue was negatively correlated with cognitive function ( r=-0.217, P<0.01). The mediation model test showed that depression had a significant direct effect on cognitive function, with an effect value of -0.141 and an effect size of 50.20%. Self-efficacy of rehabilitation exercise and fatigue had a significant mediating effect between depression and cognitive function. The effect value was -0.096, -0.026, the effect size was 34.1%, 9.3%, and the chain mediation effect of rehabilitation exercise self-efficacy-fatigue was also significant, the effect value was -0.018, and the effect size was 6.4%. Conclusions:Depression in patients with spinal cord injury not only directly affects cognitive function, but also indirectly affects cognitive function through the mediating effects of self-efficacy of rehabilitation exercise and fatigue, and the chain-type mediating effect of rehabilitation exercise self-efficacy and fatigue.
