Psycho-education combined with problem solving (PEPS) therapy is a complex cognitive-behavioural intervention that integrates individual and group therapies. Psycho-education consists of up to 4 sessions of an individual collaborative dialogue designed to build a rapport with patients, inform them about their personality disorder, discuss its effects on interpersonal relationships and social functioning, and enhance motivation for therapy. Problem solving therapy is a 12-session group intervention designed to teach people strategies for solving interpersonal problems. Throughout the twelve week problem solving therapy group sessions, participants are offered additional, optional fortnightly individual support sessions with a group facilitator.
PEPS therapy will be compared with treatment as usual. (Added 23/06/2011; previous intervention for this point can be found below).
Follow-up assessments for all participants will be completed after the initial treatment phase (weeks 5 - 10), immediately after the second treatment phase (during weeks 24 - 26) and again four and twelve months after the end of the intervention.
PEPS therapy will be compared with a standardised form of 'treatment as usual' which will include an initial care planning session with a mental health worker, including plans for future contact with services and details of alternative sources of help and support, with a follow-up session after approximately 4 weeks and a further session approximately 4 months later with additional telephone support.
Primary outcome measure
Social functioning as measured by the Social Functioning Questionnaire (SFQ). This is an 8-item self-report scale, each item scored on a scale from 0 to 3. A reduction (i.e. an improvement) of 2 points or more on the SFQ at 1 year, post-treatment follow-up is the specified clinically significant change.
Secondary outcome measures
1. Receipt and cost of services post-therapy and at one year follow-up measured by the Client Service Receipt Inventory
2. Scheduled and unscheduled service use post-therapy and at one year follow-up measured by the Client Service Receipt Inventory and a service use record check.
3. Quality of life post-therapy and at one year follow-up measured by the EQ-5D
4. Referrer's ratings of functioning post-therapy and at one year follow-up measured by the Global Assessment of Functioning
5. Anxiety and depression post-therapy and at one year follow-up meaured by the Hospital Anxiety and Depression Scale
6. A rating of the client's self-assessment of problems post-therapy and at one year follow-up
