17. Examining the Reproducibility of Meta-Analyses in Psychology

- Abstract
Meta-analyses are an important tool to evaluate the literature. Recent concerns about the reliability of single studies might also apply to meta-analyses, where the selection, inclusion, and coding of studies introduces substantial flexibility in the analysis and interpretation of results. It is essential that meta-analyses can easily be reproduced to allow researchers to evaluate the impact of subjective choices on meta-analytic effect sizes, but also to update meta-analyses as new data comes in, or as novel statistical techniques (for example to correct for publication bias) are developed. Regrettably, research in medicine reveals meta-analyses often cannot be reproduced. We plan to quantify the reproducibility of meta-analyses in psychology by reproducing twenty published meta-analyses. We will examine how much variability in effect size estimates is observed in reproduced meta-analyses, both as a function of subjective choices, as when novel statistical techniques to correct for bias are applied to published meta-analyses. Difficulties in reproducing meta-analyses, or substantial variation between original and reproduced meta-analyses, would highlight the importance of increasing the transparency and reproducibility of meta-analyses. This project has the potential to initiate a discussion about the need to increase the transparency of published meta-analyses, and results may have important implications for journal policies.

We conducted preregistered replications of 28 classic and contemporary published findings with protocols that were peer reviewed in advance to examine variation in effect magnitudes across sample and setting. Each protocol was administered to approximately half of 125 samples and 15,305 total participants from 36 countries and territories. Using conventional statistical significance (p < .05), fifteen (54%) of the replications provided evidence in the same direction and statistically significant as the original finding. With a strict significance criterion (p < .0001), fourteen (50%) provide such evidence reflecting the extremely high powered design. Seven (25%) of the replications had effect sizes larger than the original finding and 21 (75%) had effect sizes smaller than the original finding. The median comparable Cohen’s d effect sizes for original findings was 0.60 and for replications was 0.15. Sixteen replications (57%) had small effect sizes (< .20) and 9 (32%) were in the opposite direction from the original finding. Across settings, 11 (39%) showed significant heterogeneity using the Q statistic and most of those were among the findings eliciting the largest overall effect sizes; only one effect that was near zero in the aggregate showed significant heterogeneity. Only one effect showed a Tau > 0.20 indicating moderate heterogeneity. Nine others had a Tau near or slightly above 0.10 indicating slight heterogeneity. In moderation tests, very little heterogeneity was attributable to task order, administration in lab versus online, and exploratory WEIRD versus less WEIRD culture comparisons. Cumulatively, variability in observed effect sizes was more attributable to the effect being studied than the sample or setting in which it was studied.\ud \ud Data, materials and code available at: https://osf.io/8cd4r/

FOS: Psychology ,Social Psychology ,Psychology ,Higher Education ,Social and Behavioral Sciences ,Education - Abstract
The aim of this study is to improve students' sense of belonging but implementing an existing intervention by Walton and Cohen (2007) in a context outside of the US. The current study concerns a cluster randomized experiment including one control group and two experimental groups. Participants will be first-year Psychology students in the Dutch and English Bachelor programs at a Dutch university. The manipulation is administered during an in-class intervention, which includes a writing task, a reading task, and a peer discussion. Students in all conditions will do the same activities, albeit focused on different topics. The conditions differ in the overarching topic of the tasks. Students in the experimental groups will receive tasks about how challenges concerning either the social dimension of sense of belonging or the non-social/physical dimension of sense of belonging can be overcome over time. Students in the control condition will receive tasks about how one can inform themselves about certain topics. The study includes 3 moments of data collection to measure sense of belonging and well-being; A pre-test (just before the manipulation) and two post-tests (a couple of weeks after the manipulation, and towards the end of the academic year).

One of the main goals of meta-analysis is to test and estimate the heterogeneity of effect size. We examined the effect of publication bias on the Q-test and assessments of heterogeneity, as a function of true heterogeneity, publication bias, true effect size, number of studies, and variation of sample sizes. The expected values of heterogeneity measures H2 and I2 were analytically derived, and the power and the type I error rate of the Q-test were examined in a Monte-Carlo simulation study. Our results show that the effect of publication bias on the Q-test and assessment of heterogeneity is large, complex, and non-linear. Publication bias can both dramatically decrease and increase heterogeneity. Extreme homogeneity can occur even when the population heterogeneity is large. Particularly if the number of studies is large and population effect size is small, publication bias can cause both extreme type I error rates and power of the Q-test close to 0 or 1. We therefore conclude that the Q-test of homogeneity and heterogeneity measures H2 and I2 are generally not valid in assessing and testing heterogeneity when publication bias is present, especially when the true effect size is small and the number of studies is large. We introduce a web application, Q-sense, which can be used to assess the sensitivity of the Q-test to publication bias, and we apply it to two published meta-analysis. Meta-analytic methods should be enhanced in order to be able to deal with publication bias in their assessment and tests of heterogeneity.

The designing, collecting, analyzing, and reporting of psychological studies entail many choices that are often arbitrary. The opportunistic use of these so-called researcher degrees of freedom aimed at obtaining statistically significant results is problematic because it enhances the chances of false positive results and may inflate effect size estimates. In this review article, we present an extensive list of 34 degrees of freedom that researchers have in formulating hypotheses, and in designing, running, analyzing, and reporting of psychological research. The list can be used in research methods education, and as a checklist to assess the quality of preregistrations and to determine the potential for bias due to (arbitrary) choices in unregistered studies.

Due to its probabilistic nature, Null Hypothesis Significance Testing (NHST) is subject to decision errors. The concern for false positives has overshadowed the concern for false negatives in the recent debates in psychology. This is unwarranted, since reported statistically nonsignificant findings may just be 'too good to be false'. We examined evidence for false negatives in nonsignificant results in three different ways. We adapted the Fisher method to detect the presence of at least one false negative in a set of statistically nonsignificant results. Simulations show that the adapted Fisher method generally is a powerful method to detect false negatives. We examined evidence for false negatives in the psychology literature in three applications of the adapted Fisher method. These applications indicate that (i) the observed effect size distribution of nonsignificant effects exceeds the expected distribution assuming a null-effect, and approximately two out of three (66.7%) psychology articles reporting nonsignificant results contain evidence for at least one false negative, (ii) nonsignificant results on gender effects contain evidence of true nonzero effects, and (iii) the statistically nonsignificant replications from the Reproducibility Project Psychology (RPP) do not warrant conclusions about the absence or presence of true zero effects underlying these nonsignificant results. We conclude that false negatives deserve more attention in the current debate on statistical practices in psychology. Neglecting effects due to a lack of statistical power can lead to a waste of research resources and stifle the scientific discovery process.
