Brief Summary

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.

Outcome Measures

Primary Outcomes (4)

  • Change in Emotional Functioning - Linear

    Assessed with the Difficulties in Emotion Regulation Scale (DERS), which has total scores that range from 36-180, with higher scores indicating more difficulties. Outcomes are reported as slopes (scores over weeks, centered around the start of treatment, with standard errors) per condition, extracted from mixed effects/multilevel models. This measure is listed separately to permit presentation of two units of measure (that are in the same model) - the Linear unit of measure (DERS scores/week), and the Quadratic unit of measure (DERS scores/week\^2). This measure reflects the Linear measure.

    Pre-treatment, mid-treatment week 3-4, post-treatment week 6-7, follow-up week 13-14

  • Change in Borderline Personality Disorder Features - Linear

    Assessed with the abbreviated Borderline Symptom List (BSL23), which has mean scores that range from 0-4, with higher scores indicating more symptoms. Outcomes are reported as slopes (scores rescaled \*100 over weeks, centered around the start of treatment, with standard errors) per condition, extracted from mixed effects/multilevel models. This measure is listed separately to permit presentation of two units of measure (that are in the same model) - the Linear unit of measure (BSL scores/week), and the Quadratic unit of measure (BSL scores/week\^2). This measure reflects the Linear measure.

    Pre-treatment, mid-treatment week 3-4, post-treatment week 6-7, follow-up week 13-14

  • Change in Emotional Functioning - Quad

    Assessed with the Difficulties in Emotion Regulation Scale (DERS), which has total scores that range from 36-180, with higher scores indicating more difficulties. Outcomes are reported as slopes (scores over weeks, centered around the start of treatment, with standard errors) per condition, extracted from mixed effects/multilevel models. This measure is listed separately to permit presentation of two units of measure (that are in the same model) - the Linear unit of measure (DERS scores/week), and the Quadratic unit of measure (DERS scores/week\^2). This measure reflects the Quadratic measure.

Limitations and Caveats

Please note that initial results have not yet been peer-reviewed. As a pilot study conducted during COVID, this study was pivoted to offer telehealth during a time of social distancing. This likely increased amount of missing data for in-person assessed visits. Relatively low power for mixed effects models suggest alternative approaches to data analysis may need to be considered, but initial trial results are presented as originally proposed.
