This study aims to explore specific life experiences and what it means to "live as a sibling of a disabled person", by focusing on the brothers and sisters of persons with disabilities; this is a cohort that has been relatively marginalized in the field of welfare for the disabled. To this end, the author conducted 1:1 in-depth interviews with four adolescents who grew up with younger siblings who have developmental disabilities, and analyzed the meaning underlying their life experiences through phenomenological research methods. As a result, a total of five core themes of those life experiences were identified: (1) the birth of a disabled younger sibling, wherein their trials began; (2) surviving differentiation within the family; (3) ambivalence toward parents; (4) adolescence, with resurfaced psychological conflicts and relieving emotions; and (5) a future to be planned around a life of coexisting with disabled siblings. This study aims to provide basic data for social welfare intervention through an illuminating and deeper understanding of the lives of siblings of the developmentally disabled who require a high level of care.
