Key result
Illness coherence partially mediated the relationship between self-care maintenance and health-promoting behaviors in patients with stable coronary artery disease.
Why the study?
The interaction between illness perception, self-care ability, and health-promoting behaviors in patients with stable coronary artery disease remains uncertain.
Cross-Sectional (n=184)
In patients with stable coronary artery disease, illness coherence partially mediates the relationship between self-care ability and health-promoting behaviors, highlighting the importance of positive illness perception.

Supports associations of illness coherence with self-care and health-promoting behaviors in stable CAD; should not yet change practice pending prospective data.
BACKGROUND: The interaction between illness perception, self-care ability, and health-promoting behaviors (HPB) in stable coronary artery disease (SCAD) patients remains uncertain. We conducted a cross-sectional survey to explore the correlation between self-care ability, illness perception, and HPB among patients with SCAD, as well as the potential mediating role of illness perception between self-care ability and HPB. METHODS: A cross-sectional study was carried out among 184 inpatients with SCAD in Hefei, China, from December 2022 to March 2023. The Self-Care of Coronary Heart Disease Inventory (SC-CHDI, containing three dimensions: self-care maintenance, self-care management, and self-care confidence), Revised Illness Perception Questionnaire (IPQ-R, containing seven dimensions: illness duration, illness consequence, personal control, treatment control, illness coherence, cyclical timeline, emotional distress), Health-Promoting Lifestyle Profile Ⅱ (HPLP-Ⅱ) were used in the questionnaires. SPSS 25.0 software and PROCESS version 4.2 plug-in was used to analyze the mediating effect. RESULTS: HPB of SCAD patients was at moderate level. A range of factors including education level, marital status, self-care maintenance, self-care management, self-care confidence, illness coherence, and emotional distress are potential influencers of HPB. Illness coherence had a partially mediated effect between self-care maintenance and HPB (β = 0.063, 95% CI: 0.021~0.111), accounting for 20.59% of the total effect. Similarly, illness coherence had a partially mediated effect between self-care management and HPB (β = 0.055, 95% CI: 0.016~0.105), accounting for 13.78% of the total effect. However, none of the dimensions of illness perception mediated between self-care confidence and HPB. Self-care confidence directly influenced HPB, accounting for 92.40% of the total effect. CONCLUSION: It is necessary for hospital healthcare workers, community workers, and patients' families to work together to focus on the self-care ability and positive illness perception of patients with cardiovascular disease, so as to increase patients' motivation to participate in HPB and improve their quality of life.

Wang et al. (2025) conducted a cross-sectional in Stable coronary artery disease (SCAD) (n=184). Self-care maintenance and illness coherence was evaluated on Health-promoting behaviors (HPB) (β = 0.063, 95% CI 0.021~0.111). Illness coherence partially mediated the relationship between self-care maintenance and health-promoting behaviors in patients with stable coronary artery disease.
