Participants were randomly assigned to an intervention group (EFT) or a control group, with 15 individuals in each group. The intervention group received eight 90-minute sessions of EFT over eight weeks, while the control group received standard care. Pain self-efficacy and PTG were measured at three time points: pre-test, post-test, and a five-month follow-up, using validated self-reported tools. Data were analyzed using repeated measures analysis of variance (ANOVA) and Bonferroni post-hoc tests with SPSS-27.</p> <p><strong>Findings: </strong>Repeated measures ANOVA revealed significant main effects of time (F(2, 54) = 40.61, p &lt; 0.001, η² = 0.60) and group (F(1, 54) = 46.54, p &lt; 0.001, η² = 0.46) for pain self-efficacy, as well as a significant interaction between time and group (F(2, 54) = 10.97, p &lt; 0.001, η² = 0.21). For PTG, there were significant effects of time (F(2, 54) = 39.51, p &lt; 0.001, η² = 0.58), group (F(1, 54) = 43.74, p &lt; 0.001, η² = 0.42), and the interaction between time and group (F(2, 54) = 11.47, p &lt; 0.001, η² = 0.20). Bonferroni post-hoc tests confirmed significant improvements from pre-test to post-test and follow-up in the intervention group (p &lt; 0.001), while the control group showed no significant changes.</p> <p><strong>Conclusion: </strong>EFT effectively enhances pain self-efficacy and promotes PTG in women with breast cancer, with sustained benefits over time. These findings underscore the potential of EFT as a valuable therapeutic intervention for addressing the emotional and psychological challenges of breast cancer.</p> https://www.journals.kmanpub.com/index.php/psywoman/article/download/3486/6059
