Clinicians have long identified the psychological impacts and objective burdens on family members and caregivers who support loved ones with psychiatric conditions. However, there is a lack of programming available to support families with relatives who have been diagnosed with a personality disorder, and research in this area is scant. The current pilot study evaluated the impact of providing a peer-led education group for loved ones of individuals diagnosed with borderline personality disorder (BPD). A mixed-methods study design was implemented: quantitative self-report scales were used to derive scores of mastery and burden and focus groups gathered qualitative narratives. Data were collected from participants (N = 15) before and after the group intervention, as well as 4 months later. Quantitative results indicated that while participants initially reported a sense of burden in their caregiving role, their self-report of this phenomenon reduced over time following engagement with the group. The focus groups revealed that participants found the group had a positive impact on their well-being as a result of the information, skills acquisition, and support/validation they received. They also noted clinical improvements for their relatives with BPD. This study provides preliminary evidence for the effectiveness of the peer-led education group in supporting families. The results suggest that particular variables such as peer leadership, skills-based learning, and focus on caregiver wellness—rather than on the person with a diagnosis – may explain improved outcomes of this family intervention.
