Abstract：Objective To understand the current status of social support,self-efficacy,and psychological dis-tress in patients with chronic obstructive pulmonary disease(COPD),and explore the relationships among them.Methods A cross-sectional survey was conducted from November 2021 to April 2023 in the Department of Respiratory and Criti-cal Care Medicine of Haian People's Hospital,involving 408 COPD patients.General demographic information,the COPD Self-Efficacy Scale(CSES),the Social Support Rating Scale(SSRS),and the Distress Thermometer(DT)were uti-lized for data collection.Data were statistically analyzed using SPSS 25.0 software,and a structural equation model was constructed using Mplus 7.0 software to validate the mediating effects.Results A total of 430 questionnaires were dis-tributed,and 408 valid questionnaires were collected,yielding an effective response rate of 94.88％.The mean scores for CSES,SSRS,and DT in the 408 COPD patients were(92.46±20.73),(35.02±9.67),and(5.92±1.03)points,respectively.Significant differences were found in DT scores among COPD patients with different payment methods,family monthly income,course of disease,and hospitalizations due to acute exacerbations in the past year(all P＜0.05).Corre-lation analysis revealed a positive correlation between SSRS scores and CSES scores(r=0.415,P＜0.01),while both SSRS scores and CSES scores were negatively correlated with DT scores in COPD patients(r=-0.617,-0.692,re-spectively,both P＜0.01).The results of the structural equation model showed that the direct effect of social support on psychological distress in COPD patients was-0.524,and the mediating effect of self-efficacy on the relationship be-tween social support and psychological distress was-0.218,accounting for 29.38％of the total effect.Conclusion Most COPD patients experience moderate to severe psychological distress.Self-efficacy plays a mediating role in the rela-tionship between social support and psychological distress in COPD patients,and enhancing self-efficacy can further alle-viate their levels of psychological distress.
