Abstract
Background: Campbell Systematic Review (C2 review) was acknowledged to be a high quality evidence, especially in fields of social work, education and so on. However no study was found to evaluate the quality of them.

Objectives: To evaluate the quality of C2 review associated with international development, education, social welfare, crime and justice.

Methods: We downloaded all studies about the following four fields: international development, education, social welfare, crime and justice in Campbell Library. Two researchers evaluated the quality of these C2 review independently using AMSTAR tool, which includes 11 items and each item measured by Y,N, Can’t answer and Not applicable.

Results: From 2003 to 2012, 90 studies met the inclusion criteria and all of them were downloaded: 1 article (1.11%) is about international development, 13 articles (14.44%) are about education, 35 articles (38.89%) are about crime and justice and 41 articles (45.56%) are about social welfare. General speaking, the quality of C2 review was pretty good, over 80% of studies reported Y in five items (include item 1, 3, 4, 6 and 7) and over 60% of studies reported Y in five items (include item 2, 5, 8 and 9). On the other hand, only 55.56% of studies reported Y in item ‘Was the likelihood of publication bias’ assessed. And another quality index ‘Was the conflict of interest stated’? were done only by 48.89% of studies.

Conclusions: The quality of Campbell Systematic Reviews was high based on assessment results, however, some details could be improved like publication bias and interest stated.
