Mediating role of self-regulatory fatigue between psychological distress and patient activation among old patients receiving PCI
Objective To investigate the mediating role of self-regulatory fatigue between psychological distress and patient activation among elderly patients undergoing PCI,in order to establish a foundation for enhancing patient activation in this population.Methods A cross-sectional study was conducted on 267 elderly patients hospitalized in the Department of Geriatrics at Qilu Hospital,Shandong University,for PCI treatment of coronary artery disease from March to August 2023.The study utilized the Patient Self-Regulation Fatigue Scale(SRF-S),the Positivity Scale(PAM),and the Kessler Scale of Psychological Distress(K10)to evaluate self-regulation fatigue,positivity,and psychological distress in the patients.Additionally,a structural equation model was developed to investigate the relationships among these variables.Results The study found that the scores of PAM,SRF-S,and K10 were as follows:(56.49±9.52),(42.74±8.11),and(23.42±4.45)respectively.Patient activation showed a negative correlation with self-regulatory fatigue and psychological distress,while self-regulatory fatigue was positively correlated with psychological distress.Furthermore,self-regulatory fatigue was identified as playing a partial mediating role between psychological distress and patient activation,with a mediating effect of 0.198,which accounted for 53.8％of the total effect.Conclusions self-regulatory fatigue serving as a mediating factor between psychological distress and patient activation.Clinicians should prioritize addressing self-regulatory fatigue to enhance the efficacy of patient activation interventions.
