The aim of this study is to evaluate the effects of a trauma-informed yoga intervention on psychological trauma symptoms, difficulties in emotion regulation, and interoceptive awareness in young adult women.

This study will be conducted with young adult women aged 18-25 residing in a selected province. Based on a G*Power analysis, the minimum required sample size was determined to be 46 participants (intervention: n = 23; control: n = 23). Participants will be randomly assigned to the intervention and control groups using a computer-generated simple randomization method (https://www.random.org/integers/

) to ensure unbiased allocation. The intervention group will be implemented in three separate groups, each consisting of 8-10 participants, and will receive the "Trauma-Informed Yoga Intervention Program," which includes eight sessions. Each session will last approximately 45 minutes, and two sessions will be conducted per week for each group. The program will consist of group-based yoga sessions structured in accordance with trauma-informed principles. Pretest and posttest measurements will be used to assess psychological trauma symptoms, difficulties in emotion regulation, and levels of interoceptive awareness among young women.
