Comparing Dialectical-behavioral Skills Training Based on the Soler Model vs Family Education for Borderline Personality Disorder

Objectives: The high prevalence of borderline personality disorder, along with comorbid psychiatric disorders and impulsive reactions (suicide attempts, self-mutilation, substance use, and impulsive behaviors) increase the need for effective psychological interventions. In this study, the effectiveness of dialectical behavior skills training based on the Soler method and family education with individual therapies are compared in this group of patients. Methods: In this single-blind case study, eight cases were selected through a targeted sampling method based on the inclusion and exclusion criteria. The participants were divided into two groups: Intervention individually and individual intervention with family education. Both group members and the family members of the second group received dialectical behavior skills training based on the Soler model. The participants completed the borderline personality inventory, self-harm inventory, and Barratt impulsivity scale in four stages: At the beginning of the sessions, in the middle of the treatment, at the end of the treatment, and three months after treatment. Results: The data were analyzed using the Wilcoxon test, Friedman test, and Mann-Whitney U test. The results indicate the effectiveness of the dialectical behavior skills training method based on the Soler model in reducing symptoms of borderline personality disorder and self-mutilation, as well as emotion regulation improvement at the significant level of P=0.05. Discussion: This treatment is recommended as an effective and short-term method for controlling symptoms of borderline personality disorder. Family education, in addition to dialectical behavior therapy, has been shown to have a positive effect on reducing symptoms in patients.
