Experiences of a peer group for people diagnosed with borderline personality disorder: A qualitative interview study

There is a notable lack of literature evaluating peer support for people with a diagnosis of borderline personality disorder (BPD). Peer-led groups have been shown to positively impact outcomes related to empowerment, hope, and self-efficacy beliefs for consumers diagnosed with serious mental illness and may also be a helpful option for those experiencing personality disorder symptoms. We outline the coproduction of a peer group for people with a lived experience of BPD and a qualitative analysis of feedback post-group participation. Twenty-two consumers participated in post-group interviews and described their experiences of peer support. Interview transcripts were coded, and three main themes were identified: growth and change, connection and feeling understood, and creating safety. The findings suggested that participation in a coproduced peer support group for people with a diagnosis of BPD facilitated positive personal transformation as well as opportunities to develop connection through shared experiences in a safe environment grounded in mutuality. These themes were particularly powerful for participants because they countered previous experiences of not feeling safe, understood, or equal when seeking treatment. These findings support the acceptability of implementing a coproduced group for people diagnosed with BPD in a community mental health setting.
