Modeling the Dynamics of Paternal Influences on Children over the Life Course Is a heuristic model, which identifies sets of variables that predict father involvement, variables that interact to predict involvement, and variables that influence father characteristics and thereby influence involvement. It also suggests moderators and mediators of pathways from predictors to father involvement and from father involvement to child outcomes. It is a dynamic model, assuming change over the life course, while retaining paternal influences from one developmental period to another. The model is rooted in the extant literature, although it is not circumscribed by that literature. As a heuristic model, it offers a framework from which measurement models can be derived to address research questions of interest. (Contains 1 figure.)
