Glade, Bean, and Vira (2005) provided a comprehensive review of interventions targeting the transition to parenthood and a list of treatment recommendations which would be valuable to therapists and family educators. Their review is particularly helpful in guiding professionals' decisions concerning treatment modalities and reaching the population of couples transitioning to parenthood who could benefit from services. Implications for Policy The results of the current investigation have implications for public policy as well. Primarily, these relate to work-family policies and policies concerning prevention programs. In this study, couples' role arrangements and their satisfaction with their roles were related to the quality of the couples' marriage. Specifically, lower child-related task differentiation predicted lower role dissatisfaction and marital disaffection; higher child- related task differentiation predicted higher role dissatisfaction and marital disaffection. These findings, along with results from much previous research (e.g., Cowan & Cowan, 2000; Feldman, 2000; Gottman, 1994; Ruble et al., 1988) imply a need for policies encouraging greater father involvement in caring for their children, by removing institutional-level barriers to their participation and by promoting relational processes associated with their higher involvement. Difficulties associated with the transition to parenthood, including more gender-differentiated roles, have been linked to negative outcomes for men, women, and children, including the couples' decreased marital satisfaction and individual well-being (Cowan & Cowan, 2000; Gottman, 1994; Hackel & Ruble, 1992; Ruble et al., 1988; Strazdins et al., 1997) and poorer adaptation among children (Cowan & Cowan, 2000; Gottman, 1999; Shapiro, 2005). These effects have serious implications for a society dependent on its foundation of well-functioning families. As Cowan and Cowan asserted, "In our view, a serious concern about the
