Mentalizasyon Temelli Terapinin Borderline Kişilik Bozukluğu Üzerindeki Etkisi: Sistematik Bir Derleme
The Effect of Mentalization-Based Therapy on Borderline Personality Disorder: A Systematic Review

Summary/Abstract: The primary objective of this research is to provide a thorough examination of the therapeutic effects that mentalization-based therapy (MBT) exerts on borderline personality disorder (BPD). Rather than collecting primary data through fieldwork or standardized assessments, the study employed a systematic review methodology to synthesize existing empirical evidence. The literature search, which covered publications from 2010 to 2026, was conducted in both Google Scholar and PubMed databases, with eligible studies written in Turkish or English. Fifteen studies meeting the predetermined inclusion criteria were ultimately incorporated into the review. The accumulated evidence indicates that MBT contributes meaningfully to the reduction of BPD symptom severity, the enhancement of emotional regulation capacities, and the improvement of interpersonal adaptation. Particularly notable gains were observed with respect to selfinjurious behavior and impulsivity. Some studies, however, suggest that outcomes may vary depending on treatment conditions and implementation quality. Taken together, the findings provide substantial support for regarding mentalization-based therapy as an evidence-based, clinically viable intervention for borderline personality disorder.
