Effect of Digital-Supported Foot Care Education in Individuals With Type 2 Diabetes

This randomized controlled trial will evaluate the effect of digital-supported foot care education on foot care knowledge, self-care behaviors, and self-efficacy in individuals with type 2 diabetes. A total of 90 participants will be randomly assigned to an intervention group (n=45) or a control group (n=45). Participants in the intervention group will receive structured foot care education supported by videos and visual materials accessible through QR codes, together with hands-on training using a diabetic foot model. Participants in the control group will receive standard care. Foot care knowledge, self-care behaviors, and foot care self-efficacy will be assessed before and after the intervention. The study aims to determine whether digital-supported foot care education is effective in improving these outcomes among individuals with type 2 diabetes.
