To explore relationships among disease knowledge, social support, anxiety and self-efficacy in patients after total knee arthroplasty (TKA) through a chain mediating model.
A cross-sectional study.
A total of 282 post-TKA patients from three tertiary hospitals in Jinan, Shandong Province are conveniently chosen as the subjects of this study. We use established scales to assess relevant variables and apply the PROCESS 3.5 software of SPSS to construct a chain mediating effect.
The results of this study found that disease knowledge can directly affect patients' self-efficacy (β = 0.466, t = 5.227, p < 0.001). Social support and anxiety play a significant mediating role between disease knowledge and self-efficacy, with an overall mediating effect value of 0.257. After including social support and anxiety, the direct effect value of disease knowledge on self-efficacy is 0.210.
Disease knowledge in TKA patients can significantly and positively predict their post-operative self-efficacy. Between disease knowledge and self-efficacy, there is not only an independent mediating effect of social support and anxiety but also a chain mediating effect.
The patients were actively involved in the data collection for this study.
通过链式中介模型探讨全膝关节置换术（TKA）后患者疾病知识、社会支持、焦虑与自我效能之间的关系。
横断面研究。
便利选取山东省济南市 3 家三级医院的 282 例 TKA 术后患者作为研究对象。采用已建立的量表评估相关变量，并应用 SPSS 的 PROCESS 3.5 软件构建链式中介效应。
本研究结果发现，疾病知识可直接影响患者的自我效能（β=0.466，t=5.227，p<0.001）。社会支持和焦虑在疾病知识与自我效能之间发挥显著的中介作用，总中介效应值为 0.257。纳入社会支持和焦虑后，疾病知识对自我效能的直接效应值为 0.210。
TKA 患者的疾病知识可显著正向预测其术后自我效能。在疾病知识与自我效能之间，不仅存在社会支持和焦虑的独立中介作用，还存在链式中介作用。
患者积极参与了本研究的数据收集。
