# Introduction to Mediation Moderation and Conditional Process Analysis Second Edition: A Regression-Based Approach (Methodology in the Social Sciences)

#### Überblick:

Pressestimmen 'This second edition is a welcome addition to advanced regression books that can be used in doctoral courses in the social sciences or by social science researchers. Hayes maintains his usual level of clarity while adding coverage of such important topics as multicategorical variables for mediation moderation and conditional process models. Enhanced presentation of tabular materials coupled with new plots add to the reader's understanding of analyses. Incorporation of R syntax at points in the book is great as many researchers turn to R for its open access and improved graphics capabilities. I loved the first edition for my first-year doctoral course and will use the second edition in its place.'--Ramona L. Paetzold DBA Department of Management Texas A&M University 'Since I began using the first edition of this text in my graduate statistics classes in 2014 the number of theses and dissertations that include mediation and/or moderation analysis in our department has increased dramatically. Valuable new material in the second edition includes 13 new models including models with categorical variables and models with both parallel and serial mediation as well as the recently developed index of moderated mediation. My copy of the first edition is filled with my annotations on the examples of PROCESS output--in the second edition Hayes has provided useful annotations of his own. I highly recommend this book for statistics classes that include OLS mediation and moderation. It is also a terrific resource for researchers wishing to keep up with advances in moderation and mediation analysis.'--Karl L. Wuensch PhD Department of Psychology East Carolina University 'This book provides clear instruction that is accessible to graduate students while also useful to seasoned researchers looking to expand their skills for more complex regression-based analyses. The second edition provides increased clarity in interpreting PROCESS output and documents PROCESS v3 which allows for great flexibility in analyzing models. Other useful developments in the second edition include chapters on multicategorical variables incorporation of the index of moderated mediation and the appendix of instructions on how to customize PROCESS for models not covered by the templates. Hayes's approach is cutting edge in both philosophy and pragmatics. I've used the first edition extensively as a course text as well as in my own research and am excited to move to the second edition.'--Elizabeth J. Kiel PhD Department of Psychology Miami University 'Using lucid prose and abundant worked-through examples Hayes walks readers through the promise and potential pitfalls of two of the most essential--yet convoluted--tasks in social science research. Novices will find this book to be a thorough accessible description of ordinary least squares regression and a smart tutorial on mediation and moderation but it is also much more. Any seasoned researcher who has slogged through the arcane computation and agonizing decision making related to the estimation and interpretation of direct and indirect effects or the visualization and presentation of interactions will find this volume (with the accompanying PROCESS macro) to be a veritable Swiss Army knife and will return to it time and time again.'--Jeffrey G. Parker PhD Department of Psychology University of Alabama 'This text is a wonderful combination of traditional mediation and moderation using regression and extensions into more complex variations. Coverage is clear and thorough--perfect for intermediate to advanced regression learners. Updates in the second edition include a new chapter with answers to many very important and common questions which will be extremely helpful to learners. I can't wait to use this second edition with my students.'--Jocelyn H. Bolin PhD Department of Educational Psychology Ball State University'The book is very readable and conversational providing many interesting and useful examples....I found this to be a very nice book that is readable enough for the intermediate statistics user but with enough technical detail to appeal to advanced users as well....This book would make an excellent textbook for an advanced graduate-level multiple regression course or just a great resource for the interested reader.' (on the first edition)-- (09/01/2014)'This book elegantly presents both the basic and advanced issues of mediation and moderation analysis...It will be beneficial for graduate students and applied researchers who are interested in causal mechanisms using linear models....[T]his is a very good textbook for applied researchers in social sciences. It covers mediation and moderation analysis using regression techniques quite nicely....I think this book could be very useful for both preliminary and advanced readers.' (on the first edition)-- (09/01/2014) Über den Autor und weitere Mitwirkende Andrew F. Hayes PhD is Professor of Quantitative Psychology at The Ohio State University.
