Introducing the Campbell Policy Briefs series – new publications designed to inform social policy and practice decisions
Our Policy Briefs summarize findings from Campbell systematic reviews by outlining the evidence reviewed and what has been learned. The Policy Briefs also identify key remaining questions, and present ideas for future research and policy work.
