The Campbell Collaboration: Improving the evidence base for social policy and practice

Who are we?

The Campbell Collaboration is a voluntary, non-profit, international research network. We produce and disseminate systematic reviews of the effects of interventions in the social and behavioural sciences. Learn more watching our video channel.

If you are a journalist and would like to receive news about upcoming publications before they are published, or if you want to interview an author or get more information, please contact: info@campbellcollaboration.org.

Our Mission

Our mission is to enhance the evidence basis so that policymakers, practitioners, and service recipients are better equipped to make informed decisions. This can improve people’s lives, by improving the quality of public and private services.

Campbell has a small International Secretariat located in Oslo, Norway, which is hosted by the Knowledge Centre at the National Institute of Public Health, and a Secretariat in Delhi, India hosted by the Global Development Network. You can see our organizational chart here.

Our Research

We summarize research in several inter-linked research fields: crime and justice, education, international development, social welfare, knowledge transfer and methods, disability, nutrition, business and management, and methods.

Teaching Others

The Campbell Colloquium provides a meeting place open to anyone interested in evidence-based social policy. Building competence in research synthesis methodology is a key to increasing capacity for systematic reviews.

Next year we are holding the What Works Global Summit (WWGS) 2019 in Mexico, together with Coneval.

In additional to the training sessions being held in Mexico at WWGS 2019, we have run stand-alone workshops in countries all over the world. See our Events page for more information.

Systematic Reviews

  • What is a systematic review?

    A systematic review is a key step towards finding what works. It uses transparent and explicitly defined procedures to find, evaluate and synthesize the results of relevant research. The process is designed to minimize bias and to give as accurate as possible an indication of the effect of an intervention or program.
  • Campbell systematic reviews

    Campbell Systematic Reviews follow rigorous guidelines and are subject to intensive editorial scrutiny before publication. Campbell reviews: Must include a systematic search for both published and unpublished reports. Require that a protocol (project plan) for the review is approved and published in advance. Are usually international in scope. Require a minimum of two researchers, working independently, to determine matters such as study inclusion and coding.
  • Open Access

    Approved reviews are published in our open access, online Campbell Library.
