Intervening With Foster Parents to Enhance Biobehavioral Outcomes Among Infants and Toddlers.

Children in foster care face a number of challenges that threaten their ability to form attachment relationships with foster parents and to regulate their behavior and biology. The authors describe the Attachment and Biobehavioral Catch-Up (ABC) intervention, an evidence-based intervention aimed at helping foster children develop trusting relationships with foster parents and develop better biological and behavioral regulation. The authors present research that led to the development of the ABC intervention, outcome research of randomized clinical trials, and a case example of a foster parent and child who participated in the ABC intervention. Finally, issues related to the broader system of care that are likely to affect children's adjustment (e.g., foster caregiver commitment and placement stability) are discussed.
