The study will be conducted using a randomized controlled experimental design with experimental and control groups. Data will be collected between August 2025 and March 2026 in the General Surgery Clinic of Erzurum City Hospital. The study population will consist of patients who have undergone bariatric surgery at Erzurum City Hospital. A priori power analysis was performed to determine the sample size. According to the power analysis, based on Cohen's (Cohen, 2013) medium effect size of 0.5, with a significance level of 0.05, a 95% confidence interval, and 95% power to represent the population, it was determined that the study sample should include a total of 70 patients, with 35 patients in each group.
