Hawaii's Healthy Start Program (HSP) is a well-respected home visiting program for families at risk for abuse of their newborn children. The program incorporates early identification of at-risk families. Each family then begins receiving long-term home visitations. The home visiting component aims to promote child health and development and to prevent child abuse by improving family functioning and parenting. Home visitors are trained paraprofessionals working under professional supervision. The program includes both direct services and referrals to community resources. Direct services include providing emotional support to parents, encouraging them to seek needed professional help, teaching parents about child development, and role-modeling parenting skills and problem-solving techniques. In a previous study, at-risk families were randomly assigned to either HSP or no intervention. Evaluations were conducted at the time of the child's birth and at ages 1, 2, and 3 in order to assess the home environment and the development and well-being of the child. This study is a continuation study. Participants will include the original families from the previous study, as well as a new group of families who are not at risk for child abuse. By interviewing and observing these two groups of families, this study will evaluate the effectiveness of HSP in promoting children's mental health, cognitive and social-emotional development, and academic achievement in the first years of school.
