The Effect of Telephone Education and Counseling to Individuals With Stoma on Stoma Compliance and Complications: Randomized Controlled Study

The study will be conducted on individuals with stoma followed in the stoma therapy outpatient clinic of a university hospital. The effect size calculated based on the preliminary data was 2.955, indicating a very large effect. Therefore, to obtain a more conservative sample size estimate, an effect size of 0.80 was used for the a priori power analysis, in accordance with Cohen's convention for a large effect size. The sample size was calculated using G*Power version 3.1.9.7, with a significance level of α = 0.05 and a statistical power (1 - β) of 0.85. Accordingly, the required sample size was determined as 30 participants per group. The Ostomy Adjustment Inventory and Pittman Ostomy Complication Severity Index will be completed. The scales will be collected for both groups on the first day, first month, and third month postoperatively. Patients were contacted five times postoperatively to provide education and counseling. SPSS will be used for data analysis.
