 Children adopted internationally by parents in the United States often experience institutional care prior to adoption. Early institutional care may lead to inattention, deficits in inhibitory control, and insecure attachments in children. Many of these problems persist even after the child is adopted. This study will test the effectiveness of a parent training program called Attachment and Biobehavioral Catch-up for Children Adopted Internationally ABC-I. This program is designed to enhance childrens ability to regulate their attention, behavior, and physiology and to develop secure, organized attachments to their parents.
