“…This model was chosen because of theory to support the individual and interdependent links [e.g., family systems (Cox & Paley, 1997), the spillover hypothesis (Krishnakumar & Buehler, 2000), and the coercion hypothesis (Patterson, 1982)], as well as empirical work to support each link (see below), and relevance to clinical, developmental, and family researchers. The model examined the circular process by which child behavior problems elicit higher levels of coparenting conflict (e.g., Cook, Schoppe-Sullivan, Buckley, & Davis, 2009; Schermerhorn, Cummings, DeCarlo, & Davies, 2007) which, in turn, can spillover into hostile (i.e., negative) parenting practices (e.g., Benson et al, 2008; Kaczynski, et al, 2006). Hostile parenting practices then negatively influence child behavior problems (e.g., Dishion & Patterson, 2006; Wood et al, 2003), restarting the circular process.…”
