To the participants in the intervention group; the "Diabetic Foot Self-Management Training Program (DFSMTP)" will be implemented. Printed, visual, and audio training materials will be used within this training program's scope. Training will be held in the Diabetes Education Room in line with the content of DFSMTP prepared by the researcher after determining the appropriate day and time with the participants. Written (training booklet) and visual (computer and PowerPoint presentation) training materials will be used during this training. The printed training booklet will be delivered to the participants at the end of the training. DFSMTP will be held in three sessions on the same day. In order to reinforce the learning of the participants in the intervention group, DFSMTP will also be video recorded with the presentation of the researcher and this recording will be transferred to the DFSMTP YouTube channel to be created by the researcher.

To the participants in the control group; General information about the anatomy and physiology of the pancreas will be explained with the verbal lecture technique. Participants in this group will receive the training only once. Following the completion of the research, the printed training booklet and YouTube channel link information will be shared with the participants.

Diabetic Foot Self-Management Training Program will be implemented.

It is a Likert-type scale developed by Quarles in 2005 in accordance with western culture to determine the self-perception of diabetic patients in performing diabetic foot care activities. Self-efficacy is measured by scoring between 0 and 10. The scale consists of 9 items. The 9 statements that make up the scale are evaluated on the 11-digit visual scale, which is stated as "I'm not sure = 0 and very sure = 10". The lowest score of the scale is 0, and the highest score is 90. As the score obtained from the scale increases, the diabetic foot self-efficacy level increases. The Cronbach's alpha value of the sub-dimensions of the scale was 0.94. The validity and reliability study of the scale in the Turkish population was carried out by Kir Bicer and Enc (2014), and the Cronbach alpha value was found to be 0.86.

The Turkish validity-reliability study of the scale developed by Alexandra et al.(2001) to evaluate the diabetic foot information of diabetic patients was conducted by Biçer and Enç (2011). The scale consists of 5 items. Diabetic foot knowledge is evaluated using a 5-item DABÖ, a subscale. The Cronbach alpha value of the Turkish version of the scale was 0.58.

There are 16 items in the scale developed by Borges (2007) in line with the criteria of the American Diabetes Association (ADA) in order to improve foot care behaviors in patients with diabetes (51). The Turkish validity and reliability study was conducted by Kır Biçer and Enç (2014), and it was adapted as a 15-item Foot Care Behavior Scale in line with expert opinions. Each item in the scale is rated on a Likert-type scale between 1 (never) and 5 (always do). The lowest score that can be obtained from the scale is 15; the highest score is 75; High scores indicate that foot care behavior is sufficient. The Cronbach's alpha value for the Turkish version of the scale was found to be 0.83 (high reliability).

Physical examination of the foot will be done by the thesis student using the Diabetic Foot Evaluation Form developed by the Diabetes Nursing Association Diabetic Foot Study Group. In this form, the fingertips, foot body and leg heat, humidity, presence of edema; nail cutting, deformity, finger examination, presence of dorsalis pedis and tibialis posterior pulses, foot sensation test, muscle strength, ankle-arm index, deformities and shoes and ulcer evaluation if any.
