Abstract Background: Diabetes foot self-care is one of the self-management behaviors of diabetic patients leading to a reduction in the incidence of pressure ulcers and amputation. Having a valid, reliable, simple and comprehensive tool is essential in measuring the self-care behavior of diabetic patients. The aim of this study was to evaluate the psychometric properties of the Farsi version of the diabetes foot self-care bahavior scale (DFSBS) in Iran. Methods: In this cross-sectional and methodological study, 500 patients with type 2 diabetes were recruited by convenience sampling. Construct validity was assessed by exploratory factor analysis (over 300 patients) and confirmatory factor analysis (over 200 patients). Internal consistency was calculated by Cronbach’s alpha coefficient and its stability was calculated by intraclass correlation coefficient (ICC). Results: In the exploratory factor analysis, two self-care factors related to feet and shoes were extracted which had specific values of 38.49 and 1.24, respectively, and were able to account for 56.22% of the total self-care variance of diabetes foot. Confirmatory factor analysis had excellent fit model. The internal consistency and ICC of the whole instrument were 0.83 and 0.791 (95% CI: 0.575–0.925; P < 0.001), respectively. Conclusions: The Farsi version of DFSBS (F-DFSBS) has good validity and reliability, and due to its appropriate psychometric properties, this tool can be used in future studies.

Background Diabetes is the most common chronic metabolic disease that has now become a silent epidemic [1]. The prevalence of diabetes and its subsequent adverse effects has been on the rise around the world. According to the World Health Organization (WHO), in 2017, nearly 425 million people had diabetes and the number of these patients is expected to increase significantly due to population growth, obesity, aging and urbanization [2]. The number of people with diabetes in 2019 was 463 million in the world, which is * Correspondence: [email protected]; [email protected] 5 Spiritual Health Research Center, Research Institute for Health Development, Kurdistan University of Medical Sciences, Sanandaj, Iran Full list of author information is available at the end of the article
expected to increase to 700 million by 2045 [3]. Complications of diabetes lead to decreased quality of life, increased financial costs, morbidity and mortality [4]. Patients with diabetes are at risk for macrovascular (cardiovascular and cerebrovascular disease) and microvascular (retinopathy, nephropathy, and neuropathy) complications [5, 6]. Neuropathy often leads to foot ulcers and amputations, accounting for 50 to 75% of non-traumatic amputations [7, 8], and
