“…Previous research has underscored the impact that family environment plays on child development and parental mental health; however, research looking at environmental influences as potential mediators and moderators of intervention outcomes is rare (Lochman, Wells, Qu, & Chen, 2013). Limited studies have found that factors such as family cohesion, parental engagement, child temperament, parent dysfunction, and child-rearing practices moderate the effects of interventions on child outcomes (Beauchaine, Webster-Stratton, & Reid, 2005;Estrada-Martinez, et al, 2013;Jessee, et al, 2012;Kazdin, 1997;Gerstein, et al, 2009). Most relevant to the current study, Beauchaine and colleagues (2005) found that marital satisfaction moderated child outcomes in the Incredible Years Parent Training Program (WebsterStratton, 1984), specifically that for mothers reporting low marital satisfaction, interventions that included a parent training (as opposed to a child or teacher component) resulted in better outcomes with regard to externalizing behavior problems at 1-year posttreatment compared to interventions without parent training.…”
