When a family is fractured by the disclosure of intrafamilial sexual abuse, society's instinct is to gather around the most visible wound — the child who was directly harmed. Yet in every such household, other children stand at the periphery of that wound, shaped by its presence without being named as its bearers. Researchers at McGill University have given form to this quiet neglect, documenting how non-abused siblings absorb the architecture of trauma — its secrecy, its fear, its eroded boundaries — while remaining invisible to the very systems designed to heal their families.

Non-abused siblings experience significant emotional and psychological distress from living in trauma-organized family systems, including exposure to grooming, hypersexualization, and boundary violations.
