Data_Sheet_1_Influence of social support on subjective well-being of patients with chronic diseases in China: chain-mediating effect of self-efficacy and perceived stress.pdf

IntroductionThe well-being of patients with chronic diseases is an issue of widespread concern in public health. While social support is thought to have a positive effect on it, the mechanisms of its influence have not been fully addressed. Thus, we explored the possible mediating effects of self-efficacy and perceived stress to determine the relationship between social support and well-being in these patients.
MethodsA cross-sectional study was conducted among 4,657 patients with chronic diseases in China. The PROCESS Macro model 6 of SPSS was employed to explore the intermediary role between variables.
ResultsSelf-efficacy and perceived stress played a partial intermediary role between social support and subjective well-being, with an effect ratio of 48.25% and 23.61%, respectively. Self-efficacy and perceived stress had a chain intermediary effect (28.14%) between social support and subjective well-being.
DiscussionThis study suggested that improving the self-efficacy of patients with chronic diseases to cope with the changes in social support caused by the disease could reduce stress and enhance subjective well-being.

引言 慢性病患者的健康福祉是公共卫生领域广受关注的议题。尽管社会支持被认为对其具有积极影响，但其作用机制尚未得到充分阐明。为此，本研究探讨了自我效能感（self-efficacy）与感知压力（perceived stress）的潜在中介效应，以明确慢性病患者群体中社会支持与健康福祉之间的关联。
方法 本研究针对中国境内4657名慢性病患者开展横断面研究（cross-sectional study），采用SPSS的PROCESS Macro模型6分析变量间的中介作用。
结果 自我效能感与感知压力在社会支持与主观幸福感（subjective well-being）之间发挥部分中介效应，中介效应占比分别为48.25%与23.61%；二者同时在社会支持与主观幸福感之间存在链式中介效应，占比为28.14%。
讨论 本研究表明，提升慢性病患者的自我效能感以应对疾病所致社会支持的变化，可有效降低其感知压力并提升主观幸福感。
