Asymptotic and resampling strategies for assessing and comparing indirect effects in multiple mediator models
Hypotheses involving mediation are common in the behavioral sciences. Mediation exists when a predictor affects a dependent variable indirectly through at least one intervening variable, or mediator.… Expand
SPSS and SAS procedures for estimating indirect effects in simple mediation models
Researchers often conduct mediation analysis in order to indirectly assess the effect of a proposed cause on some outcome through a proposed mediator. The utility of mediation analysis stems from its… Expand
Addressing Moderated Mediation Hypotheses: Theory, Methods, and Prescriptions
This article provides researchers with a guide to properly construe and conduct analyses of conditional indirect effects, commonly known as moderated mediation effects. Expand
Effect size measures for mediation models: quantitative strategies for communicating indirect effects.
The statistical analysis of mediation effects has become an indispensable tool for helping scientists investigate processes thought to be causal. Yet, in spite of many recent advances in the… Expand
Computational Tools for Probing Interactions in Multiple Linear Regression, Multilevel Modeling, and Latent Curve Analysis
Simple slopes, regions of significance, and confidence bands are commonly used to evaluate interactions in multiple linear regression (MLR) models, and the use of these techniques has recently been… Expand
A general multilevel SEM framework for assessing multilevel mediation.
Several methods for testing mediation hypotheses with 2-level nested data have been proposed by researchers using a multilevel modeling (MLM) paradigm. However, these MLM approaches do not… Expand
Statistical mediation analysis with a multicategorical independent variable.
Virtually all discussions and applications of statistical mediation analysis have been based on the condition that the independent variable is dichotomous or continuous, even though investigators… Expand
Conceptualizing and testing random indirect effects and moderated mediation in multilevel models: new procedures and recommendations.
The authors propose new procedures for evaluating direct, indirect, and total effects in multilevel models when all relevant variables are measured at Level 1 and all effects are random. Formulas are… Expand
Contemporary approaches to assessing mediation in communication research.
Communication scholars frequently conduct research to answer questions about cause. Expand
Mediation Analysis in Social Psychology: Current Practices and New Recommendations
A key aim of social psychology is to understand the psychological processes through which independent variables affect dependent variables in the social domain. This objective has given rise to… Expand
