This macro implements the normal theory and bootstrap approaches to testing conditional indirect effects as described in Preacher, Rucker, & Hayes (2007). Using the syntax for the macro described here, analyses corresponding to each of the 5 models described in Preacher et al. can be conducted in SPSS. On this web page you will find the syntax for estimating each model and the various subcommands for doing focuses analyses. As with all macros, you must first run the macro command set to “activate” the macro. Do not modify the macro in any way. Simply run the command set as is. Once each macro is activated, the MODMED and MODMEDC commands will be available for your use until you quit SPSS.
