We examined associations between preschool children's cumulative risk exposure, dyadic interaction patterns, and self-control abilities in 238 mother–child dyads. Positive interactive synchrony, relationship ruptures, and latency to repair were micro-coded during a 3–5 minute joint challenge task. Children's self-control was assessed via two laboratory tasks and by parent report. Structural equation modeling and mediation analyses were utilized to examine the direct and indirect effects of cumulative risk on children's observed and parent-reported self-control abilities. Parent–child interactive processes of dyadic synchrony and latency to repair ruptures in synchrony were examined as mediators. Dyadic synchrony and latency to repair ruptures were found to mediate associations between cumulative risk exposure and children's behavioral and parent-reported self-control. Children exposed to more cumulative risk engaged in less dyadic synchrony and experienced longer latencies to repair ruptures with their caregiver, which in turn was associated with lower child self-control. Though cross-sectional, findings suggest dyadic synchrony and repair processes may represent viable mechanistic pathways linking cumulative risk exposure and deficits in child self-control. However, independent replications using longitudinal and experimental intervention designs are needed to determine causal pathways and inform new approaches for targeting the effects of early risk exposure through a focus on two-generational interventions.

Parent-Child interaction therapy (PCIT) has been shown to improve positive, responsive parenting and lower risk for child maltreatment (CM), including among families who are already involved in the child welfare system. However, higher risk families show higher rates of treatment attrition, limiting effectiveness. In N = 120 child welfare families randomized to PCIT, we tested behavioral and physiological markers of parent self-regulation and socio-cognitive processes assessed at pre-intervention as predictors of retention in PCIT. Results of multinomial logistic regressions indicate that parents who declined treatment displayed more negative parenting, greater perceptions of child responsibility and control in adult–child transactions, respiratory sinus arrhythmia (RSA) increases to a positive dyadic interaction task, and RSA withdrawal to a challenging, dyadic toy clean-up task. Increased odds of dropout during PCIT's child-directed interaction phase were associated with greater parent attentional bias to angry facial cues on an emotional go/no-go task. Hostile attributions about one's child predicted risk for dropout during the parent-directed interaction phase, and readiness for change scores predicted higher odds of treatment completion. Implications for intervening with child welfare-involved families are discussed along with study limitations.

Background: Child maltreatment (CM) constitutes a serious public health problem in the United States with parents implicated in a majority of physical abuse and neglect cases. Parent-Child Interaction Therapy (PCIT) is an intensive intervention for CM families that uses innovative "bug-in-ear" coaching to improve parenting and child outcomes, and reduce CM recidivism; however, the mechanisms underlying its effects are little understood. The Coaching Alternative Parenting Strategies (CAPS) study aims to clarify the behavioral, neural, and physiological mechanisms of action in PCIT that support positive changes in parenting, improve parent and child self-regulation and social perceptions, and reduce CM in child welfare-involved families.

To understand links between early experience and biomarkers of peripheral physiology in adulthood, this study examined associations between quality of early caregiving and markers of sympathetic activation and chronic inflammation in a sample of 52 low‐income mothers and their preschool‐aged children. Mothers reported on levels of positive caregiving experienced during childhood using the Structural Analysis of Social Behavior‐Intrex. Mother and child sympathetic activation was indexed via pre‐ejection period (PEP) at rest, during a dyadic social engagement task, and for children, while interacting with an unfamiliar adult. C‐reactive protein (CRP) was collected using whole blood spots to assess levels of low‐grade chronic inflammation. Results showed that mothers who reported experiencing more warm guidance and support for autonomy in early childhood displayed lower resting sympathetic nervous system activation (i.e., longer PEP) and lower chronic inflammation (i.e., CRP levels). Further, lower maternal chronic inflammation levels were associated with lower sympathetic activation (i.e., longer PEP) in their children at rest, and during social interactions with mother and a female stranger.

We examined time-ordered associations between children's compliance behavior and maternal respiratory sinus arrhythmia (RSA) in a sample of 127 child-maltreating (physical abuse, physical neglect, emotional abuse) and 94 non-maltreating mothers and their preschool-aged children. Child prosocial and aversive compliance behaviors and maternal RSA were continuously collected during a joint challenge task. Child behavior and mother RSA were longitudinally nested within-person and subjected to multilevel modeling (MLM), with between-person child maltreatment subtype and level of inconsistent parenting modeled as moderators. Both child maltreatment type and inconsistent parenting moderated the effects of child compliance on maternal RSA. Increases in children's prosocial compliance behaviors led to decreasing RSA in physically abusive mothers 30s later (i.e., increasing arousal), but predicted increases in non-maltreating mothers’ RSA (i.e., increasing calm). Inconsistent parenting (vacillating between autonomy-support and strict control) also moderated the effects of children's compliance behavior on maternal physiology, weakening the effects of child prosocial compliance on subsequent maternal RSA. These findings highlight variations in mothers’ physiological sensitivity to their children's prosocial behavior that may play a role in the development of coercive cycles, and underscore the need to consider individual differences in parents’ physiological sensitivity to their children to effectively tailor interventions across the spectrum of risk.
