Abstract
Objective:To explore the impact of patient's rumination of disease on their psychological health-related quality of life in patients with chronic obstructive pulmonary disease(COPD),and to examine the mediating role of self-efficacy between these two variables.Methods:A convenience sampling method was used to select 263 COPD patients admitted to Shanghai Second People's Hospital between June 2023 and October 2025 as study subjects,according to inclusion criteria.A general information questionnaire,the General Self-Efficacy Scale,the Rumination Scale,and the SF-12 Quality of Life Scale were used to conduct a questionnaire survey on all subjects,and the corresponding scores were calculated.Spearman correlation analysis was performed on self-efficacy,rumination on disease,and mental health-related quality of life using SPSS 21.0 software.A structural equation model was constructed using Amos 28.0 software to test the mediating effect of self-efficacy.Results:The average scores for self-efficacy,patient's rumination on disease,and mental health-related quality of life in COPD patients were(23.42±5.51),(54.65±6.84),and(62.71±8.78),respectively.Spearman correlation analysis showed that self-efficacy was significantly negatively correlated with patient's rumination on disease(r=-0.798,P＜0.001)and significantly positively correlated with mental health-related quality of life(r=0.859,P＜0.001);patient's rumination on disease was significantly negatively correlated with mental health-related quality of life(r=-0.864,P＜0.001).The structural equation model fitted well(x2/dF=2.143,IFI=0.983,TLI=0.976,CFI=0.983,RMSEA=0.066).Mediation analysis showed that self-efficacy partially mediated the relationship between patient's rumination on disease and quality of life related to mental health(indirect effect(95％CI)=-0.471(-0.574 to-0.382),P＜0.001;direct effect(95％CI)=-0.484(-0.608 to-0.373),P＜0.001;total effect(95％CI)=-0.955(—1.069 to-0.854),P＜0.001),with the mediating effect accounting for 49.32％of the total effect.Conclusion:Patient's rumination on COPD can indirectly affect their mental health-related quality of life by reducing self-efficacy.Clinical interventions should emphasize on improving patients' self-efficacy to mitigate the adverse effects of patient's rumination of COPD on their mental heal th-related quality of life.关键词
