This project examines how growing up with a chronically ill sibling may function as an Adverse Childhood Experience (ACE), causing alasting impact on the psychosocial health of the non-ill child. By reviewing existing research and conducting a qualitative study andanalysis, this study aims to expand the current ACE framework to improve trauma-informed care and future outcomes of the non-illchild. This project emphasizes the need for increased awareness among professionals as well as the need for support and earlyinterventions. Overall, the findings of this study will promote a more comprehensive and equitable support system for vulnerablechildren.
