Abstract
BACKGROUND: Chronic diseases are a global health challenge, and therefore, more attention should be paid to improving self-efficacy in people with chronic diseases. This study examined the relationship between family health and self-efficacy, and explored the mediating role of perceived social support and the moderating role of health literacy. The aim is to enhance the self-efficacy of chronic patients by improving family health, social support, and health literacy, thereby improving their physical and mental state. METHODS: A cross-sectional study based on psychological and behavioural factors was conducted, namely, the 2022 China Residents Survey, which included 5150 Chinese patients with chronic diseases. The General Self-Efficacy Scale-Short Form was used to assess self-efficacy, the Health Literacy Questionnaire-short form was used to assess health literacy, the Perceived Social Support Scale-Short Form was used to evaluate perceived social support, and the Chinese version of the Family Health Scale-Short Form was used to assess family health status. RESULTS: Family health of patients with chronic diseases had a significant positive effect on self-efficacy. Perceived social support was identified as a partial mediator between family health and self-efficacy, accounting for 59.39% of the total effect. Health literacy moderated the impact of family health on perceived social support and self-efficacy. CONCLUSIONS: Chronic diseases have become a global health challenge, and more attention should be paid to improving the self-efficacy of the chronically ill population. Our results not only facilitate the understanding of the relationship mechanisms between family health and self-efficacy in chronic patients but can also serve as a guide for healthcare workers and policymakers who wish to provide better care for patients.
