Effects of a school readiness intervention for children in foster care on oppositional and aggressive behaviors in kindergarten

One hundred ninety-two children in foster care participated in a randomized efficacy trial of a school readiness intervention, the Kids In Transition to School (KITS) Program, designed to increase literacy, social, and self-regulation skills in children before kindergarten entry. One hundred two children were randomly assigned to the KITS intervention and 90 were randomly assigned to the foster care services as usual comparison group. At the end of the kindergarten year, teachers were asked to report on the children's oppositional and aggressive behaviors in the classroom. Controlling for gender, baseline levels of parent-reported oppositional and aggressive behaviors, and level of disruptiveness in the classroom, children who had received the intervention had significantly lower levels of oppositional and aggressive behaviors in the classroom. Findings suggest that an intervention designed to increase school readiness in children in foster care can have positive effects on kindergarten classroom behavior. ► We examine the effects of a school readiness intervention on children in foster care. ► Outcomes include children's oppositional and aggressive behaviors in kindergarten. ► The intervention was associated with less oppositional and aggressive behavior. ► Implications for long-term academic and social outcomes are discussed.
