Zajac L, et al. - Researchers investigated how the implementation of the Attachment and Biobehavioral Catch-Up (ABC) intervention during infancy influences the perceived attachment security in middle childhood among 100 Child Protective Services (CPS)-referred children. Randomization of children and parents to receive either ABC or a control intervention during infancy. The Kerns Security Scale was completed by children at age nine. The analysis revealed a recording of higher levels of attachment security on the Kerns Security Scale at age nine among children whose parents received ABC relative to children whose parents had received the control intervention. This highlights the long-term advantages of intervening early to promote caregiving quality among at-risk families and displays the effectiveness of a brief 10-session intervention in supporting attachment security over the span of 8 years in a sample of CPS-referred children.
