About
Although dialectical behavior therapy (DBT) skills training is effective in the treatment of borderline personality disorder, it contains four skills modules and there is little research to guide their modular application. This study compares the unique effects of two distinct DBT skills training modules, relative to a non-DBT therapy group for adults with borderline personality disorder. Using innovative laboratory-based assessment methods, the proposed study will examine the effects of these conditions on emotional responding and interpersonal functioning, as well as clinical outcomes.
Full description
Borderline personality disorder (BPD) is a severe mental health condition with high morbidity and mortality. Although dialectical behavior therapy (DBT) is an efficacious treatment for BPD, it is resource-intensive and lengthy in its full form, involving one year of weekly individual therapy and group skills training in mindfulness, emotion regulation, interpersonal effectiveness, and distress tolerance. As a result, few patients have access to the full treatment. A better understanding of how the distinct components of DBT affect different sets of symptoms could help to streamline this treatment and personalize its use with specific patients.
Improvements in both interpersonal and emotional functioning are theorized to underlie improvements in BPD. Thus, emotion regulation and interpersonal effectiveness skills training may be particularly important components of DBT. Therefore, this study examines the unique effects of two distinct DBT skills training modules.
Participants are adults with BPD and recent, recurrent self-injurious behaviors (planned N = 81) who are randomly assigned to six weeks of DBT emotion regulation skills training (DBT-ER), DBT interpersonal effectiveness skills training (DBT-IE), or a non-skills control group. Using innovative laboratory-based multimethod assessments, this study examines the effects of these conditions on emotional responding and interpersonal functioning, as well as BPD related outcomes. Aim 1 examines the unique effects of DBT-ER and DBT-IE on their respective emotion-related (subjective and biological emotional reactivity, behavioral emotion regulation, skills use) and interpersonal (subjective and behavioral) targets, compared to the non-DBT treatment. Aim 2 examines whether improved emotional functioning predicts reductions in BPD symptoms and self-injury. Aim 3 examines whether baseline emotion dysregulation interacts with treatment condition to predict treatment response.
The proposed research is innovative in its experimental examination of the effects of DBT components on specific targets in BPD. Given the high societal costs of BPD, this work has important public health significance. Findings will inform larger studies evaluating the potential modular use of DBT components to result in briefer and more efficient individualized treatments for patients.
