Confirmatory factor analysis indicated the state of mind rating scales loaded on two factors reflecting adults’ preoccupied and dismissing states of mind. Taxometric analyses indicated the variation in adults’ preoccupied states of mind was more consistent with a dimensional than a categorical model, whereas results for dismissing states of mind were indeterminate. The second aim was to examine the degree to which the attachment states of mind of internationally adoptive and foster parents differ from those of poverty/CPS-referred parents and low-risk parents. After controlling for parental age, sex, et...

Approximately 7 years after completing the intervention, parents who had been randomized to receive ABC (n = 43) exhibited greater secure base script knowledge than parents who had been randomized to receive a control intervention (n = 51). Low-risk parents (n = 79) exhibited greater secure base script knowledge than CPS-referred parents who had received a control intervention. However, levels of secure base script knowledge did not differ between low-risk parents and CPS-referred parents who had received the ABC intervention. In addition, secure base script knowledge was positively associated with parental sensitivity during interactions with their 8-year-old children among low-risk ...

The aim of this consensus statement is, therefore, to enhance understanding, counter misinformation, and steer family-court utilisation of attachment theory in a supportive, evidence-based direction, especially with regard to child protection and child custody decision-making. The article is divided into two parts. In the first, we address problems related to the use of attachment theory and research in family courts, and discuss reasons for these problems. To this end, we examine family court applications of attachment theory in the current context of the best-interest-of-the-child standard, discuss misunderstandings regarding attachment theory, and identify fac

Attachment quality was assessed using the Strange Situation. Although attachment insecurity did not predict SIP, attachment disorganization positively predicted the early SIP steps of hostile attributional bias and aggressive goals. Children with disorganized attachments interpreted ambiguous provocations more negatively (as indicating more hostility, rejection, and disrespect and as resulting in more anger) and endorsed significantly more revenge and dominance goals than children with organized attachments. In contrast, parental sensitivity negatively predicted the later SIP step of positive expectations for aggressive responses. Results further our understanding of the adverse outcomes associated with attachment disorganization.

Some epigenetic marks are highly conserved throughout the lifespan whereas others are closely associated with specific age periods and/or particular environmental factors. Little is known about the dynamics of epigenetic regulation during childhood, especially during the period of rapid early development. Our study was aimed to determine whether the developmental program at the early stages of human development is accompanied by significant changes in the systems of genome regulation, specifically, by genome-wide changes in DNA methylation. Using a sequencing approach (MBD-seq) we investigated genome-wide DNA methylation patterns in the T-lymphocytes of three healthy toddlers at two timepoints within the second year of life. Pairwise comparison of the methylation patterns across the individuals and time points was conducted to determine common longitudinal changes in ...

In several randomized clinical trials, the intervention's efficacy has been demonstrated. Moving interventions into the community with adequate fidelity is challenging, though, and intervention effects are often much smaller than when tested in randomized clinical trials. To enhance the likelihood that ABC is delivered with high fidelity, a microanalytic fidelity assessment was developed. Using this fidelity tool as a central component of training, supervision, and certification, changes in parent sensitivity for 108 families with children ages 6 months to 2 years were as large as those seen in laboratory settings. These findings are discussed with regard to implications for moving other evidence-based interventions into the community.

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 vid...

For a variety of reasons, many parents struggle providing sensitive, responsive care. Attachment and Biobehavioral Catch-up (ABC) is a 10-session home visiting program developed to enhance parental sensitivity. ABC has been shown effective in enhancing parental sensitivity, and enhancing children's attachment security and regulatory capabilities. A key feature of the intervention is providing parents practice and feedback in interacting sensitively with their children. Effectiveness in dissemination sites has been impressive, likely because treatment fidelity is defined well and monitored carefully.

Given research demonstrating associations between parent responsiveness and children's early language development, we examined whether a parenting intervention administered in infancy improved preschool receptive language skills in children involved with the child welfare system. Attachment and Biobehavioral Catch-up (ABC) is a 10-session intervention that aims to enhance parent-child interactions. The follow-up results of this randomized clinical trial demonstrated that infants who received the ABC intervention ( n = 24) scored significantly higher on a test of receptive vocabulary at age 36 months than infants who received a control intervention ( n = 28). These results provide evidence of the critical role of parental responsiveness in supporting optimal language de...

The intervention was initially developed for foster infants, but adapted for infants living with their neglecting parents, then for young children adopted internationally, and finally for toddlers in foster care or living with neglecting birth parents. The intervention and its adaptations share a focus on the importance of providing nurturance to children when they are distressed, and following children's lead when they are not distressed. We approached intervention development from a theoretical position, with attachment theory and stress neurobiology central. But we are, at heart, clinical scientists and have been open to confirmation or disconfirmation of our ideas and hypotheses. In this paper, we describe our approach, discuss issues and challenges central to our work, and share advice for addressing similar issues and challenges.

The second aim was to explore the rate and shape of change in parenting behaviors. Participants were 24 mothers and their biological children, who were randomly assigned to ABC (n = 13) or a control condition (n = 11). A structured play assessment with each mother and her child was video-recorded prior to randomization into the study, before each intervention session, and at a follow-up visit. A total of 270 videos were coded for sensitivity and intrusiveness. Hierarchical linear growth models were used to estimate the total change in parenting qualities across the 10 intervention sessions when comparing ABC to a control condition. Piecewise hierarchical linear growth models ...

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. Twenty-month-old Jason was placed into foster care for the first time with Betty, an experienced foster mother who had previously fostered more than 50 children. Betty ran a family child care center in her home with 6 children from the neighborhood. Jason and the other foster child were sent out to another child care center, however, because Betty had the maximum number of children for whom she could care in her center. Jason had some difficulty adjusting to the transition to the other child care center every day and was difficult to manage. The day care administrator asked Betty not to bring Jason back because he required more staff time than other children, so Betty let the foster care unit know he would need a new foster home. The foster care unit moved Jason from Betty's to Charlene's home. Charlene had previously fostered only one child. When first placed with Charlene, Jason did not turn to Charlene for reassurance but rather turned away from her. Charlene was very patient and nurturing, and over time Jason gradually began turning to her when distressed. Charlene was enrolled in a 10-session intervention, the Attachment and Biobehavioral Catch-Up (ABC) intervention, that helped her provide nurturance to Jason early on and follow his lead with delight. She felt as if she could see the changes in both herself and Jason as she progressed through the intervention. As with Jason, the capacity of young children in foster care to form trusting relationships with their foster parents and to regulate behavior and physiology are affected by many things-issues including what the children bring to the new relationship, what the foster parents bring to the relationship, and how the system of foster care operates. Here we describe some of these issues that we consider most salient and then describe an intervention developed to target these issues. Finally, we discuss issues within the foster care system that affect outcomes.

The effects of both amount and method of flavored crystal administration on cortisol values were evaluated using a high sensitivity enzyme immunoassay (EIA) kit to measure cortisol. Repeated saliva sampling, one sample without the drink crystal stimulant, followed immediately by a second sample using the drink crystal stimulant, allowed direct analysis of the effect of the stimulant on cortisol values. Repeated sampling, with the stimulant used when obtaining both the first and second samples, allowed analysis of the repeatability of cortisol measurements using the drink crystals. The results suggest that the use of drink mix crystals as an oral stimulant causes a small increase in measured cortisol values, as well as an increase in the variability of these values. The results also suggest that the effect of drink crystals is sufficiently regular so that it will not distort either within or between subject comparisons as long as there is consistency in use or non-use of the stimulant.
