ABSTRACT
Objective:To investigate the relationship and intrinsic mechanism between disease uncertainty, coping style, social support and caregiver burden of primary caregivers of stroke, in order to provide a theoretical basis for reducing the burden of care and improving the quality of care for stroke caregivers.Methods:In this study, the main caregivers of 314 stroke patients hospitalized in Xinjiang Uygur Autonomous Region People's Hospital from December 2021 to May 2022 were selected by convenience sampling method, and cross-sectional surveys were conducted using the general data questionnaire, the Family Scale of Disease Uncertainty, the Simple Coping Style Questionnaire, the Social Support Rating Scale, and the Caregiver Burden Scale. Model 4 in Hayes′ SPSS-Process program was used to test the mediation effect, and Model 15 was used to test the mediation effect of social support.Results:The positive predictive effect of disease uncertainty in the primary caregiver of stroke patients on the burden of caregivers was significant ( β=0.665, P<0.01). Active coping played a partial mediating role between disease uncertainty and caregiver burden, with a mediating effect of 0.306 and a mediating effect of 31.8%. The interaction between disease uncertainty and social support had a significant predictive effect on caregiver burden ( β=-0.033, P<0.05), and the interaction item between active response and social support had a significant predictive effect on caregiver burden ( β=-0.019, P<0.05). Conclusions:Positive coping is an important psychological mechanism between disease uncertainty and caregiver burden, and social support can alleviate the influence of disease uncertainty on caregiver′s burden, and can also strengthen the weakening effect of positive coping on caregiver′s burden.
