---------------------------------------- Mediation Analysis ------------------ ---------- A brief overview and update to the field on mediation analysis can be found here: - [Beyond Baron and Kenny: Statistical Mediation Analysis in The New Millennium (Hayes, 2009)][1] ---------- **Introduction** "A mediating variable transmits the effect of an independent variable on a dependent variable. Differences between mediating variables and confounders, moderators, and covariates are outlined." [(see MacKinnon, Fairchild, & Fritz, 2010)][2]. ---------- **Methodology & Applications** This is a good place to start with links to articles, both about methodology, as well as applications. Helpful links: - Using longitudinal data for mediation. - [The Merits of Using Longitudinal Mediation (Jose, 2016)][3] - Assessing necessary sample size for mediation effects. - [Required Sample Size to Detect the Mediated Effect (Fritz & MacKinnon, 2007)][4] - Mediation analysis for longitudinal data, causal inference for indirect effects, for discrete and nonnormal variables, and in multilevel designs - [Advances in Mediation Analysis: A Survey and Synthesis of New Developments (Preacher, 2015)][5] - Mediation Analysis with Dichotomous Outcomes - [Odds Ratios for Mediation Analysis for a Dichotomous Outcome (VanderWeele & Vansteelandt, 2010)][6] - Estimating indirect effects in simple mediation models (SPSS & SAS) - [SPSS and SAS Procedures for Estimating Indirect Effects in Simple Mediation Models (Preacher & Hayes, 2004)][7] - An overview of simple and multiple mediation that explores three approaches for investigating indirect processes. - [Asymptotic and Resampling Strategies for Assessing and Comparing Indirect Effects in Multiple Mediator Models (Preacher & Hayes, 2008)][8] [1]: https://www.tandfonline.com/doi/abs/10.1080/03637750903310360?journalCode=rcmm20 [2]: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2819368/ [3]: https://www.tandfonline.com/doi/abs/10.1080/00461520.2016.1207175 [4]: https://www.ncbi.nlm.nih.gov/pubmed/17444920 [5]: https://www.ncbi.nlm.nih.gov/pubmed/25148853 [6]: https://www.ncbi.nlm.nih.gov/pubmed/21036955 [7]: https://link.springer.com/article/10.3758/BF03206553 [8]: https://link.springer.com/article/10.3758/BRM.40.3.879
