This research aims to evaluate the consequences of the disclosure of intrafamilial sexual abuse of children for the family dynamics, particularly in regard to its organization and its processes of establishment, maintenance, modification and disruption of relationships, linkages and alliances. Thus, it suggests a discussion of intrafamilial sexual abuse of children as a secrecy and addiction syndrome and as a way of maintaining cohesion of the family group, unleashing a crisis as of the disclosure of the secrecy and the resulting series of interventions by the members of the Warranty System of Children’s Rights (SGD). To facilitate the analysis of the vicissitudes experienced by the families, we proceeded to a qualitative study, by means of the narrative interview technique, which provided access to the testimony of 3 (three) mothers whose families were accompanied by a Social Assistance Specialized Reference Center (CREAS) in the municipality of Rio de Janeiro as part of the process of accountability and protection and family reorganization. The interviews were recorded with the permission of the informants, transcribed and submitted to content analysis in their thematic modality. The results point to the need for approaches to understand the family as a whole, including its links and elements of cohesion, either constructive or destructive, as a way to escape the limits imposed by interventions focused on the perpetrator-victim dyad as well as contribute to the family reorganization process.
