Acceptability and feasibility of a short-term group therapy for people with borderline personality disorder symptoms

This study evaluated the acceptance, feasibility and safety of a short-term group program for adults (18 years and older) and youth (16 to 18 years) with borderline personality disorder (BPD) symptoms. Termed Road Maps, the content and development were informed by common treatment factors identified from evidence-based therapies for BPD.

Two-hundred and eight people consented to participate in the research trial and completed baseline measures. Intervention participants rated the acceptability and subjective experience of the group. Attrition rates informed feasibility, and serious adverse events were tracked to identify potential harms.

Participant post-group ratings of the group's acceptability and subjective experience were above average across both adult and youth populations. Attrition rate after commencement of group was 38% for adults and 27% among youth. The incidence rate of emergency department presentations was reduced by 41% in the 6 months post-group, relative to 6 months pre-group.

The current study provides preliminary support for the acceptability and feasibility of a short-term group therapy program for people with a diagnosis of BPD. Road Maps may be a useful intermediate intervention in a broader model of stepped care.
