TL: The Campbell Collaboration is an international research network that produces systematic reviews of the effects of social interventions in Crime & Justice, Education, International Development, and Social Welfare.
These guidelines complement Sections 3 to 11 of the Cochrane Reviewers’ Handbook
(http://www.cochrane.org/resources/handbook/index.htm). The content has been prepared
by health promotion and public health researchers, decision-makers and practitioners experienced with both the use and conduct of systematic reviews. While these guidelines were originally developed to support the conduct of systematic reviews, they are also important for the conduct of primary research and for more informal reviews of research evidence. Many of the topics may not be unique to health promotion and public hea lth reviews, but they are issues that are important in enabling research to be used in public health policy and practice decision making.
