The population of the study consisted of urinary catheterized patients treated in the clinics of a Training and Research Hospital. G*Power power analysis was used to calculate the number of individuals constituting the sample. The effect size was set to 0.80, which is a high level according to Cohen for comparing the means of independent samples. To ensure that the statistical power of the study was above 95%, the sample size was set at a 5% significance level and the effect size was 0.5. (df = 68; t = 1.668) The sample size was calculated as 70 patients. The study is planned to be conducted with 35 patients for each of the two study groups.

Patients with urinary catheter insertion during the study periods will be identified and consent will be obtained for the study. In the first stage of the study, questionnaires will be applied face to face to the experimental group and the control group. Then, education and brochures will be given to the patients in the experimental group. Patients in the experimental group will be visited and evaluated every day until the urinary catheter is removed. After the urinary catheter is removed, the patients in the experimental group and urinary catheter self-care management scale will be applied to the control group.

The Urinary Catheter Self-Care Management Scale consists of a total of 13 items and 4 sub-dimensions.Urinary Catheter Self-Efficacy was funded by the United States National Institute of Nursing Research and developed by Wilde et al. in 2016. The scale consists of a total of 13 items and 4 subscales. The sub-dimensions of the scale are related to physician/nurse communication (items: items 7, 8, 9 and 13), avoid restriction of daily activities (items 10, 11 and 12), prevention of catheter dislodgement (items 4, 5 and 6) and self-efficacy/ fluid intake (items 1, 2 and 3). Scale items are scored on a 10-point Likert scale ranging from 1 = "I am not at all sure that I can do it" to 10 = "I am not at all sure that I can do it". "I am completely sure that I can do it" and high scores indicate high self-efficacy. is a good measure of the quality of the study.
