The Campbell Collaboration’s systematic review of school-based anti-bullying interventions does not meet mandatory methodological standards
BACKGROUND: Many published reviews do not meet the widely accepted PRISMA standards for systematic reviews and meta-analysis.

Sumario: | BACKGROUND: Many published reviews do not meet the widely accepted PRISMA standards for systematic reviews and meta-analysis. Campbell Collaboration and Cochrane reviews are expected to meet even more rigorous standards, but their adherence to these standards is uneven. For example, a newly updated Campbell systematic review of school-based anti-bullying interventions does not appear to meet many of the Campbell Collaboration’s mandatory methodological standards. ISSUES: In this commentary, we document methodological problems in the Campbell Collaboration's new school-based anti-bullying interventions review, including (1) unexplained deviations from the protocol; (2) inadequate documentation of search strategies; (3) inconsistent reports on the number of included studies; (4) undocumented risk of bias ratings; (5) assessments of selective outcome reporting bias that are not transparent, not replicable, and appear to systematically underestimate risk of bias; (6) unreliable assessments of risk of publication bias; (7) use of a composite scale that conflates distinct risks of bias; and (8) failure to consider issues related to the strength of the evidence and risks of bias in interpreting results and drawing conclusions. Readers who are unaware of these problems may place more confidence in this review than is warranted. Campbell Collaboration editors declined to publish our comments and declined to issue a public statement of concern about this review. CONCLUSIONS: Systematic reviews are expected to use transparent methods and follow relevant methodological standards. Readers should be concerned when these expectations are not met, because transparency and rigor enhance the trustworthiness of results and conclusions. In the tradition of Donald T. Campbell, there is need for more public debate about the methods and conclusions of systematic reviews, and greater clarity regarding applications of (and adherence to) published standards for systematic reviews. |
