Cognitive behavioral therapy(CBT)has consistently received much attention in the intervention approach of adolescent depression,with its application potential expanding alongside technological advancements.CBT primarily alleviates depressive symptoms by identifying and restructuring negative automatic thoughts,and incorporating behavioral activation strategies to improve emotional regulation and coping skills.Traditional face-to-face CBT(FtF-CBT)demonstrates significant advantages in establishing therapeutic alliances and addressing severe depressive symptoms in adolescents.In contrast,internet-based CBT(i-CBT)demonstrates comparable efficacy in adolescents with mild to moderate depression,while offering additional benefits such as lower cost and increased flexibility.Blended CBT(b-CBT),which integrates both online and offline modalities,enhances accessibility while retaining the personalized guidance and real-time feedback characteristic of in-person interventions,potentially improving overall treatment effectiveness.With the rapid development of digital health technologies,artificial intelligence,and virtual reality,future research is expected to further enhance the precision and efficiency of CBT in treating adolescent depression,providing a solid foundation for clinical application and theoretical advancement.
