Child Welfare Outcomes After Attachment and Biobehavioral Catch-Up Intervention Participation: A Quasi-Experimental Study.

Limited research is available examining distal child welfare outcomes after participation in evidence-based parenting interventions. To address this gap, this study employed a multi-tiered analytic approach to examine child welfare outcomes after participation in Attachment and Biobehavioral Catch-up (ABC). Using propensity score analytic techniques to establish a matched comparison group, logistic regressions examined subsequent maltreatment reports and substantiation, and survival analyses observed time to and likelihood of reunification for children who received one of three ABC curriculums compared to comparison group children (child welfare services as usual). In total, 205 children were included in the impact analysis (n = 66 treatment; n = 139 comparison); the majority of the children were White (53.7%), non-Hispanic (84.4%), males (59.5%) with an average age of 6 months (M [SD] = .50 [1.0]). Over half (56.1%) of the study sample was in out-of-home placement; 23.5% of the removed children experienced reunification. No statistically significant group differences were observed on the likelihood of subsequent or substantiated maltreatment reports. All three ABC curriculums were associated with a statistically significant increased likelihood of reunification, when compared to their matched counterpart. Additional research is warranted, though results indicate ABC may be a promising intervention to help enhance the likelihood of reunification.

Adapting with Sense: An Update on Culturally Responsive Efforts of the Attachment & Biobehavioral Catch-Up Intervention with Spanish-Speaking, Latinx Families

Sattler et al. (Global Implement Res Appl 2:12–21, 2022) raise several challenges to implementing the evidence-based intervention Attachment & Biobehavioral Catch-up (ABC) with Spanish-speaking, Latinx families. As the team working in the community dissemination of ABC, in this commentary response, we outline the ABC approach for reaching populations with diverse cultural backgrounds and languages. We also offer an update on efforts to support parent coaches implementing ABC in Spanish with Latinx families. We agree with Sattler et al. (Global Implement Res Appl 2:12–21, 2022) on the need for translated materials and cultural and language-specific supervision and have worked in recent years to address those needs. We disagree on the need for deep adaptations to the ABC intervention (if we consider “deep adaptations” as changes to the core components of an intervention), based on a broader review of the evidence on ABC’s mechanism of change and its effectiveness with Spanish-speaking, Latinx populations. We hope to contribute to this important discussion with the aim of ultimately improving services to culturally diverse populations while retaining intervention effectiveness.

Using Attachment and Biobehavioral Catch-up with young children with developmental delays: A multiple-baseline trial of attachment, sensitivity, and cortisol.

The Attachment and Biobehavioral Catchup intervention potentially offsets psychosocial risks facing dyads in which children have intellectual disability or developmental delays. In this single-case multiple-baseline study the efficacy of this intervention was tested across three such South African families. Maternal sensitivity, attachment security, and child affect regulation were measured weekly during a baseline and intervention period, using the Ainsworth Maternal Sensitivity Scales, Attachment Q-sort and salivary cortisol, respectively. Furthermore, post-intervention interviews invited parents' and intervenors' evaluations of the intervention. Visual analysis broadly indicated improvement in maternal sensitivity and attachment security across subjects over time following the introduction of the intervention, although randomisation tests were not statistically significant. Effects on affect regulation were not clearly observed and may have been influenced by case-specific variables. Parent-participants and intervenors also identified particularly helpful contributions from the intervention. Findings underscore the importance of individual-level effects evaluation, especially when implementing interventions outside the original population.

Intervening With Attachment and Biobehavioral Catch-Up to Reduce Behavior Problems Among Children Adopted Internationally: Evidence From a Randomized Controlled Trial.

Children who have been adopted internationally often exhibit persistent behavior problems. The current study assessed the efficacy of the Attachment and Biobehavioral Catch-up intervention (ABC; Dozier & Bernard, 2019) for reducing behavior problems in 122 children adopted internationally. Behavior problems were measured via parent-report using the Brief Infant Toddler Social Emotional Assessment at a pre-intervention visit and after the intervention when children were between 18 and 36 months. Children's behavior problems were also observed using the Disruptive Behavior Diagnostic Observation Schedule (DB-DOS) after the intervention when children were 48 and 60 months. Parents who received ABC reported fewer child behavior problems than parents who received the control intervention immediately after the intervention through 1.5 years post-intervention. Additionally, children whose parents received ABC exhibited fewer behavior problems within the parent context of the DB-DOS when they were 48 months old (2 years post-intervention) than children whose parents received the control intervention. There were no significant intervention effects on children's observed behavior problems within the examiner contexts. These results support the efficacy of ABC in reducing behavior problems among children adopted internationally. Trial registration: ClinicalTrials.gov NCT00816621.

Promoting Secure Attachment Relationships in Foster Families with the Attachment and Biobehavioral Catch-Up (ABC) Intervention

Promoting Secure Attachment Relationships in Foster Families with the Attachment and Biobehavioral Catch-Up (ABC) Intervention Due to a history of early adversity, foster children often show difficulties in the development of new attachment relationships. The Attachment and Biobehavioral Catch-Up Intervention (ABC) aims to promote sensitive caregiving and the development of secure attachment relationships in foster families by addressing the critical needs of foster children. The ABC intervention was implemented in Germany for the first time. The efficacy of the intervention was tested in a sample of N = 34 foster families with foster children between the ages of 6 to 24 months. Foster parents reported on parenting stress and on attachment behaviors of the child in a diary. Parenting quality was assessed in a semi-structured play situation and attachment quality was assessed with the Strange Situation Procedure. Foster parents showed higher levels of sensitivity post training (p < .001), they reported an increase in secure attachment behaviors in their foster children (p < .05), and the distribution of attachment relationships classified as secure (59 %) and disorganized (12 %) was comparable to distributions found in biological, middle class samples. Although these results still need further validation by larger control group studies, they give a first indication that the ABC program might be an effective tool to support the development of secure attachment relationships in foster families in Germany.

Improving social-emotional competence in internationally adopted children with the Attachment and Biobehavioral Catch-up intervention.

Children adopted internationally experience adverse conditions prior to adoption, placing them at risk for problematic social-emotional development. The Attachment and Biobehavioral Catch-up (ABC) intervention was designed to help internationally adoptive parents behave in ways that promote young children's social-emotional competence. Participants included 131 parent-child dyads randomly assigned to receive either ABC (n = 65) or a control intervention (n = 66). In addition, 48 low-risk biologically related parent-child dyads were included as a comparison group. At follow-up assessments conducted when children were 24 to 36 months old, internationally adopted children who received the ABC intervention had higher levels of parent-reported social-emotional competence than children who received a control intervention. In addition, observational assessments conducted when children were 48 and 60 months of age showed that internationally adopted children who received ABC demonstrated higher social-emotional competence than children who received a control intervention. Adopted children who received the control intervention, but not the ABC intervention, displayed more difficulties with social-emotional competence than low-risk children. Finally, postintervention parent sensitivity mediated the effect of ABC on observed child social-emotional competence in parent interactions, controlling for preintervention parent sensitivity. These results demonstrate the efficacy of a parenting-focused intervention in enhancing social-emotional competence among children adopted internationally.

Preliminary indications that the Attachment and Biobehavioral Catch-up Intervention alters DNA methylation in maltreated children.

Maltreatment during development is associated with epigenetic changes to the genome. Enhancing caregiving may mitigate these effects. Attachment and Biobehavioral Catch-Up (ABC) is an intervention that has been shown to improve parent-child relationships and a variety of biological and behavioral outcomes among children that are involved in Child Protective Services. This preliminary study, using a small sample size, explored whether children who received ABC exhibit different methylation patterns than those who received a control intervention. The participants included 23 children aged 6-21 months who were randomized to receive ABC (n = 12) or a control intervention (n = 11). While the children displayed similar methylation patterns preintervention, DNA methylation varied between the ABC and control groups at 14,828 sites postintervention. Functional pathway analyses indicated that these differences were associated with gene pathways that are involved in cell signaling, metabolism, and neuronal development. This study is one of the first to explore parenting intervention effects on children's DNA methylation at the whole genome level in infancy. These preliminary findings provide a basis for hypothesis generation in further research with larger-scale studies regarding the malleability of epigenetic states that are associated with maltreatment.

In Vivo Feedback Predicts Parent Behavior Change in the Attachment and Biobehavioral Catch-up Intervention

Understanding mechanisms and active ingredients of intervention is critical to training clinicians, particularly when interventions are transported from laboratories to communities. One promising active ingredient of parenting programs is clinicians’ in vivo feedback regarding parent–child interactions. The present study examined whether a form of in vivo feedback, in the moment commenting, predicted treatment retention and parent behavior change when the Attachment and Biobehavioral Catch-up (ABC) intervention was implemented in a community setting. Observational data were collected from 78 parent–child dyads (96% mothers; M age = 29 years; 81% minority; infants’ M age = 12 months; 90% minority) across 640 sessions conducted by 9 clinicians (100% female, M age = 39; 67% minority) in Hawaii. Parental behavior was assessed with a semistructured play task before and after intervention. Clinicians’ in-the-moment feedback to parents was assessed from intervention session videos. Clinicians’ frequency and quality of in-the-moment feedback predicted change in parental intrusiveness and sensitivity at posttreatment. Frequency of in-the-moment feedback also predicted likelihood of retention. Hierarchical linear modeling demonstrated strong support for these associations at the between-clinician level, and limited additional support at the within-clinician (i.e., between-case) level. Thus, a hypothesized active ingredient of treatment, in-the-moment feedback, predicted community-based ABC outcomes. The results complement lab-based evidence to suggest that in vivo feedback may be a mechanism of change in parenting interventions. Helping clinicians to provide frequent, high-quality in vivo feedback may improve parenting program outcomes in community settings.

The Effectiveness of an Attachment‐Based Intervention in Promoting Foster Mothers’ Sensitivity toward Foster Infants

Infants in foster care need sensitive, responsive caregivers to promote their healthy outcomes. The current study examined the effectiveness of the Attachment and Biobehavioral Catch-up Intervention, a short-term, targeted, attachment-based intervention program designed to promote sensitive caregiving behavior among foster mothers. Ninety-six foster mother-infant dyads participated in this study; 44 dyads were assigned to the Attachment and Biobehavioral Catch-up Intervention, and 52 dyads were assigned to a control intervention. Results of hierarchical linear modeling indicated that foster mothers who were assigned to the Attachment and Biobehavioral Catch-up Intervention showed greater improvements in their sensitivity from pre- to postintervention assessment time points when compared with foster mothers who were assigned to the control intervention. We conclude that a short-term, targeted, attachment-based intervention is effective in changing foster mothers' responsiveness to their foster infants, which is critical for foster infants' healthy socioemotional adjustment.
