First, mediation analysis provides a check on whether the program produced a change in the construct it was designed to change. If a program is designed to change norms, then program effects on normative measures should be found.

Bootstrapping for mediation analysis. The bootstrap method was first employed in the mediation analysis by Bollen and Stine (1990). This method has no distribution assumption on the indirect effect $\hat{ab}$. Instead, it approximates the distribution …

This article provides an overview of recent developments in mediation analysis, that is, analyses used to assess the relative magnitude of different pathways and mechanisms by which an exposure may affect an outcome. Traditional approaches to mediation in the biomedical and social sciences are described.

Baron and Kenny (1986) laid out several requirements that must be met to form a true mediation relationship. They are outlined below using a real-world example. See the diagram above for a visual representation of the overall mediating relationship to be explained. Note: Hayes (2009) critiqued Baron and Kenny's mediation steps approach, and as of 2019, David A. Kennyon his website stated that mediation can exist in the absence of a 'significant' total effect, and therefor…
