This randomized controlled experimental study aims to determine the effect of a cultural sensitivity training program on nursing students' cultural sensitivity, cultural awareness, and ethnocentrism levels. Fourth-year nursing students at Giresun University Faculty of Health Sciences are randomly assigned to an experimental group or a control group using simple randomization. The experimental group receives a 4-week cultural sensitivity training program (2 hours per week) including interactive lectures, discussions, case studies, video demonstrations, and role-playing activities. The control group continues with the standard nursing curriculum. Data are collected using the Intercultural Sensitivity Scale, Intercultural Awareness Scale, and Ethnocentrism Scale at baseline (pre-test) and after the intervention (post-test). The primary hypothesis is that participants receiving the training will show significant improvements in cultural sensitivity and awareness and a significant decrease in ethnocentrism compared to the control group.
