• Overview of the Campbell Collaboration• Coordinating Groups

– Crime and Justice– Education– Social Welfare– Methods– Users

• Strongly modeled after the Cochrane Collaboration


• Development of Review Questions– Mostly initiated from research groups– Some topics developed within Campbell and review groups

identified– Funders have suggested topics


• Nonrandomized designs– Quasi-experimental studies frequently included (roughly

75% of reviews)– Must be handled separately in review– Driven by research question and nature of research on topic


• Unpublished Studies– All SRs must search for gray literature– Helps address publication bias and outcome reporting bias

• Publication bias must be assessed in all reviews


• Quality assurance– Review groups develop a protocol for the SR

• Follows a standardized structure• Peer-reviewed

– External substantive experts– Methods group editor and review– Coordinating group editor

– Final review• Same as above


• Funding– Review groups must secure their own funding– Campbell Collaboration has some funding that it funnels to

selected reviews to help move them along– Not all reviews have funding– Funding usually partial (5k to 50k)


• Standardized Grading Scheme
