This study aimed at uncovering the factors influencing individuals' ability to engage in self-management of diabetic foot ulcer (DFU) and presenting a theoretical model depicting these factors and the outcomes. We used constructivist grounded theory methodology to guide this study and recruited 30 participants with an active DFU attending a wound care clinic in Ontario, Canada. The study's findings indicate that participants' engagement in self-management of DFU was influenced by internal and external factors. While some factors contributed to enhance participants' engagement in everyday self-management, others seemed to have prevented them from achieving engagement and hence the desired DFU outcomes.
