Actor–Partner Interdependence Model

Abstract The actor–partner interdependence model (APIM) is a framework for analyzing interdependent dyadic data. The model improves upon traditional regression and ANOVA analyses by estimating not only the main effects of one individual's variables, but also assessing how members of a dyad influence each other simultaneously within a single model. This entry provides an overview of the basic model specification, considerations that need to be made when using APIM, and options for statistical techniques to test actor–partner effects.
