Abstract:

Objective To explore the mediating effects of perceived stress and uncertainty tolerance on health literacy and decision satisfaction of decision makers in patient undergoing cardiac macrovascular surgery，and to provide references for improving the satisfaction of decision-making. Methods 260 surgical patient’s decision-makers in the cardiac macrovascular surgery of a hospital in Wuhan were selected by convenience sampling. All Aspects of Health Literacy Scale，Perceived Stress Scale，Intolerance of Uncertainty Scale-12 and decision satisfaction scale were used to investigate. Results 251 valid questionnaires were recovered，with an effective recovery rate of 96.54%. The health literacy score was（23.05±5.61）；the perceived stress score was（20.31±6.08）；the uncertainty tolerance score was（26.41±5.94）；the decision satisfaction score was（43.86±10.54）. The 4 variables were correlated（P<0.001）. The mediating model found that health literacy had a significant direct effect on decision satisfaction. Meanwhile，health literacy also indirectly affected decision satisfaction through 3 paths，including the independent mediating effect of perceived stress（β=0.096，P<0.001），the independent mediating effect of uncertainty tolerance （β=0.093，P=0.001），the chain mediating effect of perceived stress and uncertainty tolerance（β=0.076，P<0.001），accounting for 49.17% of the total effect. Conclusion Perceived stress and uncertainty tolerance play a mediating role in the relationship between health literacy and decision satisfaction of decision makers in cardiac macro-vascular surgery，which can improve decision makers’ health literacy，reduce perceived stress，and help them perceive surgical risks rationally，thus improving decision satisfaction.
