Methodology for Dealing With Duplicate Study Effects in a Meta-Analysis
Abstract
Study effects developed from the same data set and duplicated in more than one publication likely will bias the aggregated effects in a meta-analysis. This threat to the validity of meta-analyses in organizational research is significant. Methods of detecting overt and covert duplication of publication are presented through an analysis of five published meta-analyses. An unpublished meta-analysis of salesperson turnover is used to present the implications of nonindependence. Options for the correction of duplication are discussed. It is recommended that study effects gathered during the literature search use the proposed screening heuristic to detect and address duplicate study effects.

“To avoid this particular bias, some researchers suggest only the ‘‘original’’ or ‘‘main’’ study be included in the meta-analysis (Tramer et al., 1997).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
