Sibling placement in foster care: a review of the evidence

This research review was undertaken to explore the current evidence pertaining to sibling placement in the foster care system. The review specifically addresses the following questions: (1) Which theories inform research on siblings in foster care? (2) Which designs and methodology are used to study brothers and sisters in out of home placement? (3) How do researchers define 'siblings' when investigating child placement? and (4) What are the findings of studies pertaining to siblings in the foster care system? This review suggests that incorporation of theory into research regarding siblings in foster care is quite limited. Additionally, few studies clearly state how siblings were identified and defined. A major strength of the research, however, is the diversity of design and methodology used. Overall, the evidence presented in this review strongly supports keeping sibling groups intact unless there is a compelling reason for separate placements.
