Eighty-seven parents and primary caregivers of children aged 10 years or younger participated in a study examining the effects of the ACT Raising Safe Kids program on children's behavior. It was hypothesized that children of caregivers who complete ACT-RSK would demonstrate reduced behavior problems compared to children of caregivers in a treatment-asusual comparison group. Results indicated that the behavior of children of treated caregivers improved significantly more than comparisons on a measure of conduct problems. Although further research is needed, these results suggest that ACT-RSK may contribute to the prevention of behavior problems in early childhood.
