An Examination of the Cognitive-Behavioral Therapy Approach for Major Depressive Disorder Based on Attachment Theory: A Systematic Review

Summary/Abstract: The purpose of this systematic review is to examine the effectiveness of the Cognitive Behavioral Therapy (CBT) approach in the treatment of Major Depressive Disorder based on attachment theory. The study employed a systematic review methodology; no field studies were conducted, no data were collected from participants, and no psychometric assessment tools were used. The literature search was conducted in the Google Scholar, PubMed, Web of Science, and PsycINFO databases; full-text studies in English published between January 2010 and December 2025 were evaluated. The search process was conducted in accordance with the PRISMA 2020 guidelines and based on predefined inclusion and exclusion criteria. Of the 1,856 studies identified through the literature search, 10 randomized controlled trials that met the criteria were included in the analysis. The findings of the reviewed studies indicate that cognitive-behavioral therapy is an effective psychotherapy approach for reducing symptoms of major depressive disorder. It was determined that CBT interventions structured on the basis of attachment theory or incorporating attachment assessment not only reduce depressive symptoms but also support increased attachment security, reduced attachment anxiety and avoidance, and improved interpersonal functioning. Furthermore, it has been observed that internet-based CBT interventions are as effective as in-person CBT, and that digital interventions offer an important alternative that can increase access to treatment. Meta-analysis findings reveal that initial insecure attachment patterns do not hinder treatment success and that attachment security can be developed during the therapeutic process. In conclusion, it is assessed that integrating attachment theory into the cognitive-behavioral therapy process enhances clinical outcomes in the treatment of major depressive disorder and contributes to more lasting psychological recovery.
