The Invisible Connection: A Qualitative Analysis of the Experience of Support-Seeking Siblings of Individuals With...

Nearly 80% of children within the U.S. live with a sibling, and siblings exert a unique and typically lifelong influence on one another. Past research supports an influence between psychopathology of one individual and the psychological functioning of their siblings. Recently this relationship has been examined in the context of borderline personality disorder (BPD), with findings suggesting that siblings of individuals with BPD are at heightened risk of developing psychiatric disorders and engaging in maladaptive behaviors. Beyond the influence siblings have on one another, there is growing work demonstrating that many siblings of individuals with mental health difficulties face unique challenges in terms of balancing care for themselves and care for their siblings, and yet do not have resources available for these specific challenges. The current study analyzes the text from 456 written statements from applications submitted by self-identified siblings to a therapeutic program designed for family members of people with borderline traits. A qualitative analysis is utilized to examine statements, and three themes are identified: sibling relationship dynamics, concern for family members, and overall tone and emotionality. Through discussion of themes and related subthemes, we describe the experiences of sibling dyads and make a case for increased opportunities for these siblings to access care and support, to improve their outcomes.
