Version 4 of PROCESS is described and documented in the 3rd edition of Introduction to Mediation, Moderation, and Conditional Process Analysis. SPSS and SAS users will find that the documentation in the 2nd edition of the book applies to version 4 as well. Documentation for the R version of PROCESS is only available in the 3rd edition.
Click the button below to go to the Canadian Centre for Research Analysis and Methods, where you download PROCESS version 4.2 (released 13 November 2022) through the Resource Hub. When you do so, a .zip archive will download in accordance with your browser settings. The installation and use of PROCESS is documented in Appendix A as well as throughout the book. Appendix A also contains the model number templates for preprogrammed models. Instructions for creating your own models or modifying numbered models can be found in Appendix B. The appendices are not electronically available except in the e-book edition. PROCESS version 2 and 3 are no longer available or supported.
ATTENTION: MacOS "Catalina" users: This version of MacOS locks file access that makes it appear that files are missing and affects the operation of SPSS and the ability to install PROCESS. Here is a video that might be helpful in working around this problem.
