Abstract：Objective To explore the chain-mediating effect of illness perception and social support between self-regulatory fatigue and aging expectations in elderly patients with COPD.Methods Using the convenient sampling method,a total of 149 elderly patients with COPD were investigated using the General Information Questionnaire,Self-Regulatory Fatigue Scale,Brief Illness Perception Questionnaire,Social Support Rating Scale,and Expectations Regarding Aging Scale.Results The mean scores of self-regulatory fatigue,illness perception,social support,and aging expectations in elderly patients with COPD were(53.57±15.83),(45.92±14.83),(31.00±9.93),and 50.00(29.00,61.00),respectively.Aging expectations were negatively correlated with self-regulatory fatigue(r=-0.876,P＜0.01)and illness perception(r=-0.877,P＜0.01),but positively correlated with social support(r=0.895,P＜0.01).Mediation analysis showed that the total indirect effect of self-regulatory fatigue on aging expectations was-0.682.Illness perception and social support individually accounted for 43.10%and 24.50%of the total effect,respectively,while their combined chain-mediated effect contributed 8.35%to the total effect.Conclusion Elderly patients with COPD exhibit high level of illness perception and self-regulatory fatigue,but a low level of aging expectation and social support.The chain-mediated effects of illness perception and social support between self-regulatory fatigue and aging expectations are statistically val-id.Medical staff should actively improve patients'illness perception,enhance social support,reduce self-regulatory fatigue,and thereby elevate aging expectations.
