Yes.
Key evaluation results:
ABC has been extensively evaluated. Some of the randomized clinical trial data are provided below. In a randomized clinical trial (Bernard et al, 2015) with children at risk for neglect who were involved with Child Protective Services, children receiving the ABC intervention showed more typical cortisol production, with higher wake-up cortisol levels and a steeper diurnal slope (morning to evening) than children receiving the control intervention (DEF: Developmental Education for Families).
In this same randomized clinical trial (Bernard et al, 2012) with parents identified as being at risk for neglecting their young children, children who received the ABC intervention had significantly lower rates of disorganized attachment (32%) and higher rates of attachment (52%) than children in the control intervention.
Children whose parents received ABC also showed better inhibitory control than children in the control condition, with fewer children touching prohibited toys than children in the control condition (Lind et al., 2017).
Parents in the ABC group show increases in sensitivity and decreases in intrusiveness relative to parents in the control condition (Yarger et al., 2016). The effect size for sensitivity changes is as large in community settings as in laboratory trials (Caron et al., 2016).
Is there an evaluation currently in progress or planned?
Yes. Also, examining the efficacy of neonatal intervention
