Characterization of groups of siblings in residential child care in Spain

International guidelines recommend that groups of siblings remain together when protective measures are taken. Although this is a deeply rooted practice in most countries, research has found no conclusive evidence of the benefits of this practice, so further knowledge in this field is required. This work aims to describe the characterization of groups of siblings in residential child care. The sample consists of 281 children and adolescents who were in residential care, of which 42% were composed of groups of siblings. Case files were analysed, and the main results indicate that those who are cared for with their siblings are younger, have longer stays and have been subjected to neglect to a greater extent than those who are alone and reunification with their family is more complicated than for the rest. These results are discussed with regard to the scientific literature in this field and conclude with the need to carry out preventive actions and to make decision‐making criteria about groups of siblings more flexible.
