Background and Aims: Traits of Borderline Personality Disorder in mothers are associated with deficits in Reflective Functioning, which lead to dysfunctional parent-child interactions and the intergenerational transmission of emotional difficulties. This highlights the need for targeted interventions. The present study aimed to compare the effectiveness of Dialectical Behavior Therapy and Mentalization-Based Treatment on Parental Reflective Functioning in mothers with Traits of Borderline Personality Disorder.
Materials and Methods: This quasi-experimental study used a pretest-posttest design with a 3-month follow-up and included a control group. The sample included 45 mothers from Tehran, Iran, in 2025, selected through convenience sampling and randomly assigned to two experimental groups and one control group. The first experimental group received 12 sessions of Dialectical Behavior Therapy, each lasting 90 minutes, whereas the second experimental group received 12 sessions of Mentalization-Based Treatment, each lasting 90 minutes. The control group was placed on a waiting list. Data were collected using the Borderline Personality Inventory (Leichsenring, 1999) and the Parental Reflective Functioning Questionnaire (Luyten, 2017). Data were analyzed using Mixed Multivariate analysis of variance with SPSS software (version 27).
Results: The results indicated a significant time× group interaction effect for the total Reflective Functioning score and its dimensions 2η = 0.558, F(14,74) = 6.661, P>0.001). Both treatments were effective in increasing the total Reflective Functioning score and its dimensions (P<0.05). However, Mentalization-Based Treatment was more effective than Dialectical Behavior Therapy in improving the total Reflective Functioning score (MD=-9.80, P<0.05).
Conclusion: The findings of the present study can inform educational, therapeutic, and supportive policies for families.
