Abstract: Emotion-focused therapy(EFT), an experiential approach centered on emotions as the core agent of change, has received increasing attention amid the trends of transdiagnostic conceptualization of emotional disorders and the integration of psychological therapies. This review summarizes recent evidence on the application of EFT for depression, anxiety, complex trauma, personality disorder, and transdiagnostic emotional disorders, and discusses its progress from mechanistic, cultural, and clinical practice perspectives. Current research indicates that EFT facilitates the transformation of maladaptive emotions into adaptive ones, thereby alleviating core symptoms, enhancing emotional regulation, and improving self-functioning. Process-outcome studies further highlight that enhanced emotional awareness, the establishment of emotion transformation pathways, and the quality of the therapeutic relationship are key mechanisms underlying its effectiveness. Despite accumulating evidence for its efficacy, the implementation of EFT in China faces challenges, including the lack of large-scale, multi-center, long-term randomized studies, which limits the generalizability of its efficacy and the systematic validation of transdiagnostic mechanisms. Future research should advance EFT along three directions: localization, evidencebased development, and technological integration. Overall, with its unique emotional processing theory and experiential techniques, EFT provides a valuable framework for intervening in emotional disorders and is poised to play an increasingly influential role in integrative psychological treatment.
