Abstract

Abstract: 
Objective: Self-management efficacy is a key factor influencing rehabilitation outcomes in postoperative lung cancer patients. In the context of digital healthcare, the role of eHealth literacy has become increasingly prominent. However, the psychosocial mechanisms through which it affects self-management efficacy remain unclear. This study aimed to explore the relationships among eHealth literacy, perceived social support, and self-management efficacy in postoperative lung cancer patients, and to examine the mediating role of perceived social support between eHealth literacy and self-management efficacy.

Methods: A cross-sectional survey was conducted from April to July 2024 using convenience sampling, involving 354 postoperative lung cancer patients from a tertiary hospital in Shanghai. Data were collected using a general information questionnaire, the eHealth Literacy Scale (eHEALS), the Perceived Social Support Scale (PSSS), and the Strategies Used by People to Promote Health (SUPPH) questionnaire. Pearson correlation analysis was performed using SPSS 27.0. Structural equation modeling was conducted using Amos 28.0, and the Bootstrap method (5000 resamples) was employed to test the mediating effect of perceived social support.

Results: The mean score of patients' self-management efficacy was 92.80 ± 23.41. Correlation analysis revealed significant positive correlations among eHealth literacy, perceived social support, and self-management efficacy (r ranged from 0.399 to 0.567, p < 0.01). The structural equation model demonstrated a good fit (χ²/df = 1.562, CFI = 0.996, RMSEA = 0.040). Mediation analysis indicated that eHealth literacy not only directly and positively predicted self-management efficacy (β = 0.321, p < 0.001) but also exerted an indirect effect through the mediating role of perceived social support (β = 0.135, p = 0.002). The mediating effect accounted for 29.6% of the total effect.

Conclusion: The self-management efficacy of postoperative lung cancer patients requires improvement. eHealth literacy is a significant predictor of their self-management efficacy, partially mediated through perceived social support. Clinical interventions should not only focus on enhancing patients' eHealth literacy but also aim to strengthen their perceived social support through strategies such as reinforcing family and social support networks and providing personalized psychological support. This integrated approach can more effectively improve self-management efficacy and rehabilitation outcomes.
