Standalone DBT Group Skills Training Versus Standard (i.e. All Modes) DBT for Borderline Personality Disorder: A Natural Quasi-experiment in Routine Clinical Practice.

We describe a naturally occurring, real-world comparison of outcomes following 6 months in standalone DBT skills training group for adults with Borderline Personality Disorder (BPD) without recent suicidal or severe self-harming behaviours and standard (i.e. all modes) DBT for BPD including patients with recent high-risk behaviours. 34 patients chose standalone skills over waiting for standard DBT and 54 were offered standard DBT. Dropout was higher for standalone skills than standard DBT (38.2% vs. 16.7%). No statistically or clinically significant differences were found among completers between conditions on borderline symptoms, general psychopathology, and suicide ideation. There was a moderate effect for standalone skills on hopelessness and emotion regulation difficulties which may have reflected non-equivalence of treatment groups. Significant methodological factors limit generalisability of findings which offer support for feasibility of standalone DBT skills as an effective alternative to waitlist for standard DBT for at least some patients with BPD in the community.

Outcomes for 18 to 25-year-olds with borderline personality disorder in a dedicated young adult only DBT programme compared to a general adult DBT programme for all ages 18.

AIM: Targeting young adults with borderline personality disorder (BPD) for treatment may carry significant social and clinical benefits. We aimed to evaluate a community-based Dialectical Behaviour Therapy (DBT) programme delivered exclusively to young adults with BPD. METHODS: We describe a naturally occurring non-equivalent, quasi-experimental comparison of outcomes for young adults (18-25 years) with BPD following 1 year of treatment in either a young adult only DBT programme or a general adult DBT programme (18+ years). Twenty-four young adults enrolled in a community-based young adult DBT programme open only to 18- to 25-year-olds with BPD. Another 13 young adults, also 18-25 years, enrolled in a general adult DBT programme open to all ages above 18 years. Both treatment conditions offered all modes of standard DBT for 1 year. Participants completed a battery of self-report measures on mental health symptoms at baseline and again at treatment completion after 1 year. Discharge rates at 2 years post-treatment completion were also recorded. RESULTS: Better outcomes were found on borderline symptom severity and general psychopathology among completers of young adult DBT, with a large effect size for treatment condition as well as greater clinically significant change. Discharge rates from mental health services 24 months later were also higher for completers of young adult DBT. CONCLUSIONS: There may be advantages in delivering DBT to young adults in an age-specific programme, possibly due to group cohesion. Methodological limitations apply, such as small sample size and non-randomization. Further controlled research is needed.
