The type of this research is a randomized controlled experimental study. The aim of the research is to determine the effectiveness of virtual classroom training and SMS support in improving foot care behaviour and foot care self-efficacy in diabetic patients.

The basic questions the research aims to answer are:

• Is virtual classroom training effective in improving foot care behaviour and foot care self-efficacy in diabetic patients?
• Are SMS-supported interventions effective in improving foot care behaviour and foot care self-efficacy in diabetic patients? Within the scope of the research, participants are expected to attend virtual classroom training and read the SMS sentences sent.

In order to examine the effects of virtual classroom training and SMS-supported interventions, researchers created a control group, a virtual classroom, an SMS support group, and an SMS-supported virtual classroom group.
