A comparison of methods to test mediation and other intervening variable effects
Open accessAbstract
A Monte Carlo study compared 14 methods to test the statistical significance of the intervening variable effect. An intervening variable (mediator) transmits the effect of an independent variable to a dependent variable. The commonly used R. M. Baron and D. A. Kenny (1986) approach has low statistical power. Two methods based on the distribution of the product and 2 difference-in-coefficients methods have the most accurate Type I error rates and greatest statistical power except in 1 important case in which Type I error rates are too high. The best balance of Type I error and statistical power across all cases is the test of the joint significance of the two effects comprising the intervening variable effect.

“The z' test indicated that change in basic psychological need satisfaction was a significant mediator of the direct relation (z' = -2.26, p < .01).”

“However, using cross-sectional samples with SEM models is generally considered an acceptable way to measure mediation when longitudinal data are not available.[24][25][26]”

In the citing paper
“This method offers greater statistical power than both the traditional causal steps approach popularized by Baron and Kenny (1986) and the Sobel test (Sobel 1982), which uses normal theory confidence intervals (e.g., Hayes, 2009; MacKinnon, Lockwood, Hoffman, West, & Sheets, 2002).”

The check wasn’t confident either way, so it gives no verdict — never disputed.
In the citing paper
“The final sample size included in the analysis was deemed adequate for the use of confirmatory factor analysis (CFA) and moderation effects which require a minimum sample size of 200 or more (Wolf et al., 2013;MacKinnon et al., 2002).”

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.
