Intervening to enhance behavioral and biological outcomes among young children following orphanage care. Young children who have lived in baby homes in Russia face challenges as they move into foster care. Attachment and Biobehavioral Catch-up (ABC), a 10-session home visiting intervention used primarily for high-risk parents, was adapted to help foster parents in Russia interact with their post-institutionalized children sensitively. The intervention was expected to enhance children’s attachment security and self-regulation. This presentation will describe early outcomes from a study assessing the effectiveness of the ABC intervention with children moving from orphanages to foster care placement in Russia.  These findings will be discussed along with other findings related to the effectiveness of the ABC intervention.
