This study will examine whether Emotional Freedom Techniques (EFT) can reduce pain intensity, pain catastrophizing, and functional-emotional impact in nursing students with primary dysmenorrhea. Eligible participants will be randomly assigned to an intervention group or a control group. The intervention group will receive EFT-based support, and the control group will continue their usual coping practices. Study outcomes will be measured before the intervention, after the intervention, and at follow-up. This study may provide evidence for a safe, non-pharmacological approach to support students with primary dysmenorrhea.
