Young children with disabilities may be at elevated risk for behavior problems as well as maltreatment. preventive approaches that can be infused into early intervention services are needed to support parents, build competencies among young children, and enhance protective factors that may temper risk. Two interventions--Stepping Stones Triple P, an evidence-based parenting intervention, and Preventing Child Abuse Through Parent-Provider Partnerships, a workforce intervention--were selected for use in two studies designed to strengthen families of young children with disabilities. These studies, collectively known as the Family Networks Project, are described with specific attention to how the interventions used in these studies fit within a protective factors framework and within early intervention service systems. Information on project implementation and evaluation is presented, along with recommendations for future research.
