After discharge, the individuals in the experimental group were given training by the researcher through training booklets prepared by the Association of Wound Ostomy Incontinence Nurses and video conference in four interviews. The first interview was done on the 5th day after discharge, the second on the 10th day, the third on the 15th day, and the fourth on the 2nd month.

Individuals with stoma in the control group received the training of the company representative that sells stoma materials routinely in the hospital.

Educational booklets are given according to the type of stoma. The individual with the stoma was told that the researcher was always reachable by phone and could communicate if he had any problems. The individuals with stoma in the experimental group received the training of the company representative that sells stoma materials, which is routinely given in the hospital. After discharge, training was given by the researcher via video conference in a total of four interviews. The first interview was done on the 5th day after discharge, the second on the 10th day, the third on the 15th day, and the fourth on the 2nd month. A post-test was conducted at the end of the 4th training interview, which was administered via video conferencing.

The Stoma Self-Efficacy Scale was developed to measure self-efficacy in individuals with stoma. The scale was developed by Bekkers et al. (1996). It is a 22-item scale with two sub-dimensions. Items in this scale are in 5-point Likert type. The first sub-dimension is the "Stoma Care Self-Efficacy" sub-dimension, which consists of the first 13 items. The second sub-dimension is the "Social Self-Efficacy" sub-dimension consisting of the remaining nine items. The minimum score that can be taken from the scale is 22, the maximum score is 110, and an increase in the score from the scale indicates high levels of self-efficacy. There is no reverse scored item in the scale.

It was created by Maekawa (2000) and later this scale was arranged by Simmons et al. (2009) in the form of Ostomy Adjustment Scale-23, consisting of 23 items and 4 sub-dimensions. OAS-23, a self-assessment scale, is a scale used to evaluate the level of adjustment in individuals with stoma. 4 sub-dimensions in this scale: accepting (includes items 1, 3, 4, 6, 9, 14, 15, 19, 23.), anxiety/worry (12, 13, 17, 20, 21 items) .), social cohesion (includes items 5, 7, 8, 11), and anger (includes items 2 and 10). At the same time, there are 3 items (16, 18 and 22) that are not included in any sub-dimensions. Each item of the scale is evaluated in a 5-point Likert type.

After the individuals with stoma in the experimental group were trained by the researcher throughout the study, it was evaluated that they could or could not perform their own stoma care under the supervision of the researcher. However, the status of individuals in the control group for maintaining stoma care is based on their own statements.
