Good Morning,
I want help to handle a pair of binary moderators.
I wanted to examine if participant’s sex or grandparent’s sex moderated the relationship between two grandparent contact measures: childhood and adolescence, and a caring scale. Using Cohen et al (2010) and Jaccard et al (2003) I centered the two contact measures, dummy coded the two sex variables and created four interaction terms: AContact (A) + CContact (C) + Psex (P) + Gsex (G) + AP + CP + AG + CG. The AP interaction was significant. When I was going compute the conditional effect of adolescence contact on caring for male and female participants I got stuck with the Grandparent’s sex variable. None of the books mentioned offered advice. Do I include it calculations? or just drop it, and compute the two simple slopes for participant’s sex.
Any suggestion or references will be greatly appreciated.
TIA, Steve (Pace University, NYC)
