Study type
Interventional
Description of intervention(s) / exposure
The intervention is a stepped care group treatment program. Following diagnostic assessment confirming trial eligibility participants will then be randomised to either stepped care group treatment or tailored individual treatment. The stepped care group treatment will involve two phases: an initial 12 week phase, followed by an extended 16 week phase. Not all participants will proceed from the initial to the extended phase. Criteria for continuing to the extended phase is continuing to meet diagnostic criteria for BPD (> 4 criteria) or severity on GAF < 65 at completion of the initial phase. The group intervention is a skills training (GST) program. The first phase of group treatment will involve 12 consecutive weekly, 2 hour sessions. The second phase of group treatment will provide 1 x 2 hour sessions for 16 consecutive weeks. The groups will be facilitated by 2 psychologists. The GST program is a skills based therapy that includes four modules: mindfulness (focusing on the 'here and now'), crisis coping skills, skills in how to identify and manage emotions and skills for improving interpersonal communication and relationship building.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation involved contacting the holder of the allocation schedule who was 'off site".
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Computerised sequence will randomly allocate participants to stepped or tailored care. Randomisation will be blocked to ensure severity on the GAF, parasuicidal behaviour, age, and gender are balanced between groups.
Masking / blinding
Open (masking not used)

Efficacy
Statistical methods / analysis
Using the sample size calculation method via G Power, in order to produce a medium to large effect with the power of approximately 80% for an independent t-test, each group should have 64 participants, totalling 128 participants.

Similar randomised controlled trials investigating the efficacy of DBT included sample sizes ranging from 27 - 180 (McMain et al, 2009; Tormoen,et al. 2014 & Verheul et al, 2003). The current RCT will adopt a sample size of 128.
