Development of a Self-Care Influencing Factor Scale in High-Risk Patients with Diabetic Foot Lesions

Abstract

 The aim of this study was to develop a factor scale influencing self-care behavior in patients at high risk of diabetic foot lesions. The participants comprised 106 foot care practitioners with a minimum of 10 years of nursing experience, who had received foot care training. An anonymous self-report questionnaire survey was conducted using the postal survey method, yielding a response rate of 47.2%（50 respondents）with a 100% valid response rate. Exploratory factor analysis with oblique promax rotation was employed to scale the questions, and reliability was confirmed through cronbach’s alpha coefficient. In addition, covariance structure analysis was performed to validate the model fit. The alpha coefficient was .798 for certain factors, slightly below the .800 threshold for high internal consistency but exceeding .800 for all other scales. While some factors in the model fit assessment exhibited insufficient values, none had alpha coefficients below .50; thus, the assessment tool was deemed usable. However, due to the inadequacy of certain values and reliance on integrated responses from nurses concerning their patients, the tool warrants reevaluation using actual patients as subjects.
