Mediating effect of self-efficacy on self-perceived burden and kinesiophobia in patients with coronary heart disease after percutaneous coronary intervention in China: a cross-sectional study
Abstract
Objectives To analyse the current state of kinesiophobia, self-perceived burden and self-efficacy in patients with coronary heart disease (CHD) following percutaneous coronary intervention (PCI). In addition, to study the mediating effect of self-efficacy between self-perceived burden and kinesiophobia. Design Cross-sectional study. Setting A tertiary-level hospital in Anhui Province, China. Participants We recruited a total of 255 patients for this study. The eligible subjects were patients diagnosed with coronary artery disease who underwent successful transradial PCI. The exclusion criteria included patients who had both diseases affecting their exercise ability and severe psychiatric disorders. Primary and secondary outcome measures We used questionnaires consisting of the Self-Efficacy Scale for Chronic Disease (SESC), the Tampa Scale for Kinesiophobia Heart (TSK-SV Heart), the Self-Perceived Burden Scale (SBPS) and a general information data sheet to obtain participant information. SPSS Bootstrap was used for mediated effects analysis. Results The total patient score for kinesiophobia, self-perceived burden and self-efficacy was 42.96±5.00, 24.36±7.84 and 7.61±1.46, respectively. Kinesiophobia was negatively and positively associated with self-efficacy (r=−0.368, p<0.01) and self-perceived burden (r=0.271, p<0.01), respectively. The mediating effect of self-efficacy between self-perceived burden and kinesiophobia in patients was 0.046 (95% CI 0.018 to 0.081),…
How strong is the evidence?
Evidence Hub reads this as a cross-sectional, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause. Reported size: 255 participants or records.
