When moderation is mediated and mediation is moderated.

Journal of Personality and Social Psychology, 2005

Effect size measures for mediation models: quantitative strategies for communicating indirect effects.

Psychological methods, 2011
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 estimation and testing of mediation effects, little attention ...

Mediations

2019
This chapter analyzes the processes of mediation which affect or orient what classic policy analysis calls “the implementation” of policy. We show the localized recontextualizations and interpretations of these policies, that is, the mediations, by intermediate actors.

Statistical mediation analysis with a multicategorical independent variable.

British Journal of Mathematical & Statistical Psychology, 2014
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 frequently are interested in testing mediation hypotheses ...

Mediators, moderators, and tests for mediation.

Journal of Applied Psychology, 1984
Abstract : The following points are developed. First, mediation relations are generally thought of in causal terms. Influences of an antecedent are transmitted to a consequence through an intervening mediator. Second, mediation relations may assume a number of functional forms, including nonadditive, nonlinear, and nonrecursive forms. Special attention
