Abstract
INTRODUCTION: Diabetic foot is a major burden and threat to individuals, families and society, making it imperative to promote good self-management behaviour. However, although nurses have provided these patients with excellent health knowledge, their self-management remains unsatisfactory. Although researches have shown that self-management requires family involvement, no research has been conducted in China on family function, specifically in the diabetic foot. Therefore, this study aimed to explore the relationship between self-management, family functioning, and health information adoption behaviour and explain the formation's reason. METHOD AND ANALYSIS: We will conduct a mixed-methods study using an exploratory sequential study design in Zhejiang, China. In the first phase, cross-section research will be conducted using a convenient sampling strategy on 225 diabetic foot patients. SPSS V.26 was used for correlation and multiple stepwise regression analyses. Structural equation modelling will be performed by using AMOS V.24. The researchers will conduct a semistructured interview to collect qualitative data and use NVivo to analyse. Ultimately, we will 'triangulate' to integrate quantitative and qualitative data. ETHICS AND DISSEMINATION: This study received ethical clearance from the Ethics Review Committee, the affiliated Sir Run Run Shaw Hospital of Medicine School, Zhejiang University (approval no: 2023-0145). All data collection processes will abide by health and safety measures required by the national government. Written informed consent will be obtained from all participants. The study will produce one paper that will be disseminated, to local stakeholders and participants, via local and international conferences and publications in peer-reviewed journals.
