Abstract

Despite research supporting the effectiveness of dialectical behavior therapy (DBT) for borderline personality disorder (BPD), few studies have examined how DBT leads to clinical change. DBT is theorized to lead to improved clinical outcomes by enhancing the capacity for emotion regulation, including improvement in skills (e.g., mindfulness and distress tolerance) for managing emotional distress and impulsive behaviors. Therefore, the aim of this study was to test whether improvements in mindfulness and distress tolerance indirectly affect the relationship between DBT skills training and clinical outcomes. The sample consists of 84 patients diagnosed with BPD who were enrolled in a randomized controlled trial comparing 20 weeks of DBT-skills group (DBT-S) to an active waitlist control. Mindfulness and distress tolerance were assessed at baseline and at the end of the 20 weeks. BPD symptoms, general psychiatric symptoms, and social adjustment were assessed at the end of 20 weeks and combined into a latent variable representing a broad assessment of general psychopathology. Relative to the waitlist control group, improvements in mindfulness and distress tolerance each independently indirectly affected the relationship between DBT-S and posttreatment general psychopathology. Findings suggest that DBT-S exerts its effects on outcomes through improvements in mindfulness and distress tolerance. These findings support the significance of mindfulness and distress tolerance in DBT-S for BPD. Limitations, future directions, and clinical implications are discussed.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
