Details

This workshop is focused on the application of principles of linear modeling, primarily using OLS regression, to exploring questions about mediated (i.e., indirect) and moderated (i.e., interaction) effects. Topics include classic and contemporary approaches to testing mediation and moderation hypotheses, path analysis, indirect and direct effects, probing and plotting interactions, and analytically integrating moderation and mediation analysis. We will spend roughly one-third of the workshop talking about partitioning effects into direct and indirect components and how to quantify and test hypotheses about indirect effects, one-third talking about estimating, testing, probing, and visualizing interactions in linear models, and then one-third discussing the integration of moderation and mediation by discussing how to conceptualize and test for conditional indirect effects (“moderated mediation”) and whether moderated effects are mediated (mediated moderation).  Examples will focus on the use of the PROCESS procedure (available for both SPSS and SAS) written by Dr. Hayes, which implements the methods described in this workshop and greatly simplifies computational tasks that historically have been tedious.
 
Participants should have a good working knowledge of the principles and practice of multiple regression and elementary statistical inference. No knowledge of matrix algebra is required or assumed.
