Abstract Mediation analysis has become one of the most popular statistical methods in the social sciences. However, many currently available effect size measures for mediation have limitations that restrict their use to specific mediation models. In this article, we develop a measure of effect size that addresses these limitations. We show how modification of a currently existing effect size measure results in a novel effect size measure with many desirable properties. We also derive an…

Equivalence of two least-squares estimators for indirect effects
In social and behavioral sciences, the mediation test based on the indirect effect is an important topic. There are many methods to assess intervening variable effects. In this paper, we focus on the
Sample Size Planning for Detecting Mediation Effects: A Power Analysis Procedure Considering Uncertainty in Effect Size Estimates
This study proposed an easy-to-use sample size planning method for testing mediation with uncertainty in effect size estimates considered, and conducted simulation studies to demonstrate the impact of uncertainty inEffect size estimates on power of testing mediation, and to provide sample size suggestions under different levels of uncertainty.
Sample Size Requirements for Simple and Complex Mediation Models
The results not only present practical and general guidelines for substantive researchers to determine minimum required sample sizes but also improve understanding of which factors are related to sample size requirements in mediation models.
A comparison of the type I error rates of three assessment methods for indirect effects
ABSTRACT Mediation analysis is a popular statistical analysis verifying the relation between an independent variable and a dependent variable through a mediator. There are three traditional tests to
Two-level moderated mediation models with single-level data and new measures of effect sizes.
This article proposes a two-level moderated mediation (2moME) model with single level data, and develops measures to quantify the moderated mediation (moME) effect sizes for both the conventional
An Equivalence Testing Approach for Evaluating Substantial Mediation
In the past, researchers often used the nonsignificance of the direct path from the predictor to the outcome, in conjunction with a significant indirect effect, to make claims regarding ‘full
Estimation of total mediation effect for high-dimensional omics mediators
By applying the proposed estimation procedure, it is found that 38% of the age-related variations in systolic blood pressure can be explained by gene expression profiles in the Framingham Heart Study of 1711 individuals.
The indirect effect is omitted variable bias. A cautionary note on the theoretical interpretation of products-of-coefficients in mediation analyses

This paper intends to remind communication scientists that the indirect effect as estimated in mediation analyses is a statistical synonym for omitted variable bias (i.e. confounding or suppression).
Dynamic change meets mechanisms of change: Examining mediators in the latent change score framework
Researchers in behavioral sciences are often interested in longitudinal behavior change outcomes and the mechanisms that influence changes in these outcomes over time. The statistical models that are
BANOVA: Bayesian Analysis of Experiments in Consumer Psychology
This article introduces Bayesian extension of ANOVA for the analysis of experimental data in consumer psychology. The approach, called BANOVA, addresses some common challenges that consumer


Effect size measures for mediation models: quantitative strategies for communicating indirect effects.
The first new effect size index is described is a residual-based index that quantifies the amount of variance explained in both the mediator and the outcome and the second new effectsize index quantifying the indirect effect as the proportion of the maximum possible indirect effect that could have been obtained, given the scales of the variables involved.
Monotonicity of effect sizes: Questioning kappa-squared as mediation effect size measure.
It is argued that κ² is not an appropriate effect size measure for mediation models, because of its lack of the property of rank preservation, and can lead to paradoxical results in multiple mediation models.

In the present article, 11 methods for constructing the confidence intervals (CIs) of the standardized indirect effects were evaluated via a computer simulation and consistently showed that the percentile bootstrap, the bias-correctedbootstrap, and the likelihood-based approaches had the best coverage probability.
A Simulation Study of Mediated Effect Measures.
Analytical solutions for point and variance estimators of the mediated effect, the ratio of the mediated to the direct effect, and the proportion of the total effect that is mediated were studied
Identification, Inference and Sensitivity Analysis for Causal Mediation Effects
Causal mediation analysis is routinely conducted by applied researchers in a variety of disciplines. The goal of such an analysis is to investigate alternative causal mechanisms by examining the
Power and sample size calculations for evaluating mediation effects in longitudinal studies
Three methods for testing the hypothesis on the longitudinal mediation effect are evaluated: the joint significant test, the normal approximation and the test of b methods.
A General Approach to Causal Mediation Analysis
The approach is general because it offers the definition, identification, estimation, and sensitivity analysis of causal mediation effects without reference to any specific statistical model and can accommodate linear and nonlinear relationships, parametric and nonparametric models, continuous and discrete mediators, and various types of outcome variables.
Explanation of Two Anomalous Results in Statistical Mediation Analysis
Two computer simulations were conducted to examine the findings of previous studies of testing mediation models and found that stagnation and decreases in statistical power as a function of the effect size of the a path occurred primarily when the path between M and Y, b, was small.
Asymptotic and resampling strategies for assessing and comparing indirect effects in multiple mediator models
An overview of simple and multiple mediation is provided and three approaches that can be used to investigate indirect processes, as well as methods for contrasting two or more mediators within a single model are explored.
R squared effect-size measures and overlap between direct and indirect effect in mediation analysis
Two approaches for handling the overlap between the direct and indirect effect in mediation analysis are discussed, but none of them is without disadvantages.
