Different individuals use the same words in different ways.
some words that sometimes mean the same things and sometimes mean different things are:
covariate, confounder, mediator, suppressor, moderator.  Sometimes people say any of those words for any continuous independent (predictor, right-hand-side) variable.

What are your variables? What substantive questions are you using the data to answer?
What values can the categorical variables have?

Is this an experiment (one or more of the IV's represents random assignment)?

Hi everyone,

I am very, very new to mediation and could use some help. I know the steps
to Baron and Kenny's method but am unsure of how to actually do them in
SPSS.

I have two categorical IVs (which I have dummy coded), the interaction term
of these categorical variables and three continuous mediators.

So, here are my questions:

1) If I'm wanting to look at mediation of one of my IV effects, would I
enter that variable in by itself in Step 1 as a predictor and leave the
other IV out? Or can I assess both at the same time by entering both as my
IVs? Or should I just enter the full model (IV1, IV2, IV1*IV2)?

2) If I'm wanting to look at mediation at it pertains to my interaction
term, do it enter the interaction term as the sole predictor in Step 1 or do
I also enter IV1 and IV2 as covariates?

I just really need someone to walk me through these steps, but after that
I'm golden.

Thank you!

tbf
