We conducted an exploratory research study looking at fathering interactions as they relate to the wraparound care given by the Partnership for Kids or PARK Project, a school-based system of care in Bridgeport, Connecticut. The questions posed by our research focused on how fathers’ positive interaction measured by their levels of engagement and accessibility can moderate the effect of the school-based system of care intervention on the mental health outcomes of children with serious emotional disturbances. We found that, although not statistically significant, children’s access to their father did have a moderating effect on CBCL scores for internalizing behaviors and total problems. There was very small change in CBCL scores for externalizing behaviors. Further, the moderating effect of father accessibility and father engagement had a lasting effect as a moderator through 12 months into the intervention, especially with regard to internalizing behavior scores.
