Introduction to Mediation, Moderation, and Conditional Process - Analysis

Informationen zum Autor Andrew F. Hayes! PhD! is Professor of Quantitative Psychology at The Ohio State University. He is the author of Statistical Methods for Communication Science and coeditor of the Sage Sourcebook on Advanced Data Analysis Methods for Communication Research! and has published many journal articles and book chapters in the areas of research methods! data analysis! public opinion! political communication! social psychology! and numerous other topics. Dr. Hayes is one of the founding editors of Communication Methods and Measures! for which he serves as Editor-in-Chief through 2015. He teaches research design and data analysis at the undergraduate and graduate levels and frequently conducts workshops on moderation and mediation analysis throughout the world. His website is www.afhayes.com. Klappentext Explaining the fundamentals of mediation and moderation analysis! this engaging book also shows how to integrate the two using an innovative strategy known as conditional process analysis. Procedures are described for testing hypotheses about the mechanisms by which causal effects operate! the conditions under which they occur! and the moderation of mechanisms. Relying on the principles of ordinary least squares regression! Andrew Hayes carefully explains the estimation and interpretation of direct and indirect effects! probing and visualization of interactions! and testing of questions about moderated mediation. Examples using data from published studies illustrate how to conduct and report the analyses described in the book. Of special value! the book introduces and documents PROCESS! a macro for SPSS and SAS that does all the computations described in the book. The companion website (www.afhayes.com) offers free downloads of PROCESS plus data files for the book's examples. Unique features include: *Compelling examples (presumed media influence! sex discrimination in the workplace! and more) with real data; boxes with SAS! SPSS! and PROCESS code; and loads of tips! including how to report mediation! moderation and conditional process analyses. *Appendix that presents documentation on use and features of PROCESS. *Online supplement providing data! code! and syntax for the book's examples.
