Recent studies have found significant but relatively modest associations in parenting across generations, suggesting additional influences on parenting than experience in the family of origin. The present prospective, cross-generational study of at-risk men (Oregon Youth Study) focuses on fathers' negative discipline practices with their 2-to 3-year-old children. The theoretical model is based on a dynamic developmental systems approach to problematic family functioning, which points to the importance of developmental systems, including family risk context and key influential social interactional systems, and emphasizes influence that is directly pertinent to the outcome of interest. Path modeling indicated that the men's poor and harsh discipline practices were predicted by partners' problem behavior (substance use and antisocial behavior) and negative discipline practices, as well as by poor discipline experienced in the family of origin, men's own problem behavior, ages at which they became fathers, and family socioeconomic status were controlled. Findings indicate the importance of focusing on influence dynamics across parents.Keywords three generations; discipline; mothers; fathers; dynamic developmental systems It has long been assumed that many of the parenting behaviors we employ with our children were learned from our own parents (Caspi & Elder, 1988). Until recently, however, most evidence regarding this association came from retrospective studies (Covell, Grusec, & King, 1995;Olsen, Martin, & Halverson, 1999) or from studies in which one agent reported on more than one generation (e.g., Chassin, Presson, Todd, Rose, & Sherman, 1998;Chen & Kaplan, 2001). A number of recent studies using long-term prospective data sets with multiagent, multimethod designs have found significant associations between the parenting experienced as a child and the parenting practices later employed in the family of procreation. Notably, however, these associations have been relatively modest (Belsky, Jaffee, Sligo, Woodward, & Silva, 2005;Capaldi, Pears, Patterson, & Owen, 2003;Conger, Neppl, Kim, & Scaramella, 2003;Hops, Davis, Leve, & Sheeber, 2003;Smith & Farrington, 2004; Thornberry, FreemanGallant, Lizotte, Krohn, & Smith, 2003).The fact that the intergenerational association for parenting is limited when subjected to rigorous testing indicates that there are influences on parenting in addition to experiences in the family of origin. The availability of prospective intergenerational data allows for the opportunity to identify factors that influence early adults' parenting over and above the behavior modeled by their parents. The present study builds on a prior study (Capaldi et al., 2003) examining intergenerational continuity in parenting for an at-risk sample of young men (the Oregon Youth Study, OYS) by testing a theory-driven model of factors that may influence Corresponding author: Deborah M.
