A psychoeducational group intervention for family and friends of youth with borderline personality disorder features: Protocol for a randomised controlled trial

Background: Caring for a person with borderline personality disorder is associated with poor outcomes including elevated psychological distress and burden. This study will compare the effectiveness of two brief psychoeducational programs for carers of youth presenting for early intervention for borderline personality disorder features. The protocol for this study is presented here. Methods: The study is a single-centre parallel group, randomised controlled trial. As a family unit, relatives, partners and friends ('carers') are randomly allocated to one of two treatment arms to receive either an online borderline personality disorder psychoeducation program, or both the online psychoeducation group and a face-to-face group program, Making Sense of Borderline Personality Disorder. Carers are assessed at baseline and follow-up (4 weeks after the intervention). It is expected that participants who received the combined group and online programs will have better outcomes than those who received the online program alone. The primary outcome is carer burden, assessed using the negative appraisal subscales of the Experience of Caregiving Inventory. Secondary outcomes include positive experiences of caregiving, coping, self-rated personality disorder knowledge, psychological distress, expressed emotion and quality of life. Discussion: This will be the first published evaluation of a psychoeducational intervention for carers of youth with borderline personality disorder features using a randomised controlled trial design. The results have the potential to inform clinicians and carers about the effectiveness of brief interventions designed to support families and friends of young people with borderline personality disorder, and what medium those interventions should utilise.
