The study falls within the scope of Early Care and Intervention. It was proposed to contribute to the approach of intellectual disability (ID), from a systemic-family perspective, stressing the contribution of socio-family agents in the construction of the phenomenon. In order to do so, he gave voice to the brothers and sisters of children with Down’s syndrome, investigating their socio-cognitive representations (conceptions, attitudes and feelings) about themselves, his brothers and sisters in ID situation and his role in the family. The qualitative methodological design used in-depth interviews oriented by thematic script as tools for collecting/producing information, based on family-centered approaches. The study group consisted of 18 Chilean brothers and sisters and 2 immigrants attending three stimulation and early care centers in Santiago of Chile. The results point to defined conceptions about ID, attitudes ranging from a temporary distance to a greater degree of understanding of the phenomenon, initial feelings of frustration, grief, rage and personal and family invisibilization and professional projections associated with ID.
