요약Selective reporting detection tests and adjustment methods evaluate the presence of selective reporting and estimate bias-adjusted average effect sizes to address its impact on meta-analytic results. Available tests and adjustment methods are univariate by design, meaning they only handle a single effect size per primary study, but meta-analyses of education research typically include multiple effect sizes per study. Extending previous methodological studies evaluating the performance of detection tests when dependent effect sizes are present, this study evaluates approaches to estimating bias-adjusted average effect sizes in meta-analyses involving dependent effects. This simulation study examines the performance of three adjustment methods (i.e., Regression-based methods, Trim & Fill, and 3-parameter selection models) to estimate bias-adjusted effect sizes under various conditions. In practice, researchers may or may not report adjusted average effect sizes using either a contingent or non-contingent strategy based on the statistical significance of selection bias detection tests. To this end, this simulation study also compares the accuracy of adjusted effect sizes when they are reported if contingent versus non-contingent on the statistical significance of tests for the presence of selection bias. When selective reporting censoring is high, in general, results indicate poor estimation performance for all selective reporting adjustment methods regardless of approach used to handle dependent effect sizes. Variation by study conditions is reported, including: overall average effect size, amount of between-study heterogeneity, within to between-study heterogeneity ratio, and average sample sizes from primary studies. Performance differences between the contingent and non-contingent strategies for adjusted estimates were primarily observed within the regression-based methods - specifically the aggregating and two modeling approaches - with minimal differences identified in the other estimation methods or approaches to dependency. Results can help guide researchers on the best practices for selective reporting tests and methods to use given certain study conditions. Future research is needed to improve current methods or identify new methods to estimate adjusted effect sizes, particularly when the amount of selective reporting is suspected to be at a higher probability.
