All families will be evaluated on a yearly basis when the child is in 1st, 2nd, and 3rd grade. Interviews will be conducted with the parents, children, and teachers. Parent interviews will focus on family functioning, including mental health of the parents, parenting attitudes and behaviors, quality of the home environment, and any domestic violence or substance abuse that occurred. In addition, the child's health and development, as well as use of any community resources will be assessed. Interviews with the children and teachers will focus on assessing the child's behavior and emotional well-being. The family's home environment, the interaction between the parents and children, and the children's classroom behavior will be observed. Each child will also undergo developmental testing. All measurements will be collected at each yearly visit.
