摘要:There has recently been increased interest in the potential for formal and informal networks to aid interventions with biologic families in helping them achieve reunification in the context of the child protection system. When group support is provided to families, the creation of a network of social support seems to be a consequence. The article analyzes the conceptualization of social support in order to create social support networks and the benefits on the intervention with families in the framework of the child protection system through a systematic review. From a wide search 4348 documents, finally 14 articles were included in the reviews. Results show that social support is considered a process by which social resources are provided from formal (professional services and programs associated with those services in any off the protection, health of educational systems) and informal (extended family, friends, neighbors and acquaintances) networks, allowing the families to confront daily moments as well as in crisis situations. This social support is related to emotional, psychological, physical, instrumental, material and information support that allow families to face their difficulties. Formal and informal networks of child protection systems contribute to social support, resilience, consolidation of learning and the assistance of families to social intervention programs.
