Public Health"],"abstract":"\n Objective<\/jats:title>\n To examine the relationships among self-efficacy, self-management behaviour and quality of life in community-dwelling older adults with chronic conditions, to test the mediating effect of self-management behaviour on the relationship between self-efficacy and quality of life, and to provide a theoretical basis for the development of a community-based chronic disease management nursing model led by specialist nurses.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n A convenience sampling method was used to recruit 189 older patients with chronic diseases from a community health service centre in Jiange County, Guangyuan City, Sichuan Province, between November 2025 and February 2026. Participants completed a general information questionnaire, the Chinese version of the Self-Efficacy for Managing Chronic Disease Scale, the Self-Management Behaviour Scale for Chronic Patients, and the Short Form 12 Health Survey. Data were analysed using SPSS 26.0, employing descriptive statistics, independent-samples t-tests, one-way analysis of variance, and Pearson correlation analysis. The mediating effect was examined using the PROCESS macro and verified with the bias-corrected bootstrap method.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Among community-dwelling older adults with chronic diseases, the mean score for the physical component summary (PCS) of HRQOL was 45.87\u202f\u00b1\u202f8.92, and that for the mental component summary (MCS) was 48.23\u202f\u00b1\u202f9.14. The mean score on the Chronic Disease Management Self-Efficacy Scale was 47.63\u202f\u00b1\u202f12.84, and the mean self-management behaviour score was 72.41\u202f\u00b1\u202f9.86. Pearson correlation analysis showed that SF-12 scores were positively correlated with C-SEMCD scores (\n r<\/jats:italic>\n \u202f=\u202f0.523,\n p<\/jats:italic>\n \u202f&lt;\u202f0.01) and with self-management behaviour scores (\n r<\/jats:italic>\n \u202f=\u202f0.481,\n p<\/jats:italic>\n \u202f&lt;\u202f0.01), and that C-SEMCD scores were positively correlated with self-management behaviour scores (\n r<\/jats:italic>\n \u202f=\u202f0.562,\n p<\/jats:italic>\n \u202f&lt;\u202f0.01). Mediation analysis verified the partial mediating role of self-management behaviour. The indirect effect was 0.187 (38.6% of the total effect) for the PCS model, and the indirect effect was 0.203 (41.2% of the total effect) for the MCS model.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n Among community-dwelling older adults with chronic diseases, self-efficacy has a direct correlation with health-related HRQoL, and also correlates with HRQoL indirectly via self-management behaviour. Self-management behaviour acts as a partial mediator between the two variables. In clinical nursing practice, targeted efforts to improve patients\u2019 self-efficacy may help foster positive self-management behaviours and may ultimately contribute to better HRQoL.<\/jats:p>\n
