Abstract: (50 Views)
Background: Borderline Personality Disorder (BPD) and vulnerable narcissism, although distinct constructs, are interconnected. Dialectical Behavior Therapy (DBT) and Mindfulness-Based Stress Reduction (MBSR) can play an effective role in addressing these aspects. However, there is a clear research gap due to the lack of studies directly examining the effects of DBT and MBSR on vulnerable narcissism symptoms in individuals with BPD, and no comparative studies have been conducted to date.
Aims: This study aimed to compare the effectiveness of DBT and MBSR on symptoms of vulnerable narcissism in individuals with BPD.
Methods: The present study employed a quasi-experimental design with a pre-test, post-test, control group, and a three-month follow-up period. The statistical population consisted of all women with BPD who sought treatment at a therapeutic clinic in Rasht, Iran, in 2024. A total of 45 individuals were purposefully selected and randomly assigned to three groups of 15 participants (two intervention groups and one control group). The experimental groups underwent 8 sessions of MBSR (Kabat-Zinn, 2009) and 10 sessions of DBT (Linehan, 1993). Data were collected using the Pathological Narcissism Inventory (Pincus et al., 2009) and analyzed using repeated-measures ANOVA with SPSS version 26.
Results: The results revealed a significant difference between pre-test and post-test scores, as well as follow-up scores for narcissism (P< 0.05). While there was no significant difference between the two treatments over time, both treatments demonstrated significant improvements in narcissism compared to the control group (P< 0.05).
Conclusion: Based on the findings, DBT and MBSR are two effective therapeutic approaches for improving narcissism symptoms in individuals with BPD. These results can aid clinical psychologists in designing more.
