This study was conducted as a randomized controlled trial to examine the effect of the Emotional Freedom Technique on preoperative anxiety and postpartum depression in high-risk pregnant women who had decided to undergo planned cesarean delivery. Data were collected from women diagnosed with high-risk pregnancy who had made the decision for planned cesarean delivery in the last trimester of pregnancy. In the Emotional Freedom Technique group, the technique was applied during the preoperative period, while the standard care group received only standard care. The study was completed with 30 women in the Emotional Freedom Technique group and 32 women in the standard care group. The "Pregnant Introductory Information Form," the "State-Trait Anxiety Inventory," and the "Edinburgh Postnatal Depression Scale" were used as data collection tools. Pre-test and post-test applications of the scales were performed, and on the 21st day postpartum, the Edinburgh Postnatal Depression Scale was administered. For data analysis, descriptive statistics, independent samples t-test, paired samples t-test, ANOVA, and Pearson correlation analyses were used.
