This randomized controlled study aims to evaluate the effect of a drama-based coloring storybook on children's fear, anxiety, and pain management during the perioperative process. The study will be conducted with children aged 6-9 years who are scheduled for elective surgery. Participants will be randomly assigned to either an intervention group receiving the drama-based coloring storybook or a control group receiving routine preoperative care. Levels of fear, anxiety, and pain will be assessed using validated measurement tools at predefined perioperative time points. The findings are expected to contribute to evidence-based, child-centered perioperative care practices.
