RESUMEN
This study investigated emotion transmission among peers during middle childhood. Participants included 202 children (111 males; race: 58% African American, 20% European American, 16% Mixed race, 1% Asian American, and 5% Other; ethnicity: 23% Latino(a) and 77% Not Latino(a); Mincome = $42,183, SDincome = $43,889; Mage = 9.49; English-speaking; from urban and suburban areas of a mid-Atlantic state in the United States). Groups of four same-sex children interacted in round-robin dyads in 5-min tasks during 2015-2017. Emotions (happy, sad, angry, anxious, and neutral) were coded and represented as percentages of 30-s intervals. Analyses assessed whether children's emotion expression in one interval predicted change in partners' emotion expression in the next interval. Findings suggested: (a) escalation of positive and negative emotion [children's positive (negative) emotion predicts an increase in partners' positive (negative) emotion], and (b) de-escalation of positive and negative emotion (children's neutral emotion predicts a decrease in partners' positive or negative emotion). Importantly, de-escalation involved children's display of neutral emotion and not oppositely valenced emotion.

Physiological regulation may interact with early experiences such as maltreatment to increase risk for behavior problems. In the current study, we investigate the role of parasympathetic nervous system regulation (respiratory sinus arrhythmia [RSA] at rest and in response to a frustration task) as a moderator of the association between early risk for maltreatment (i.e., involvement with Child Protective Services; CPS) and externalizing behavior problems in middle childhood. CPS involvement was associated with elevated externalizing problems, but only among children with average to high RSA at rest and average to high RSA withdrawal in response to frustration. Effects appeared to be specific to CPS involvement as the association between cumulative risk (i.e., nonmaltreatment experiences of early adversity) and externalizing problems was not significantly moderated by RSA activity. These findings are consistent with the theoretical idea that the consequences of early maltreatment for later externalizing behavior problems depend on children's biological regulation abilities.

This study evaluated whether Attachment and Biobehavioral Catch-up (ABC), a parenting intervention, altered the attachment representations of parents (average age of 34.2 years) who had been referred to Child Protective Services (CPS) due to risk for child maltreatment when their children were infants. 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 and CPS-referred parents. Mediational analyses supported the idea that the ABC intervention enhanced parents' sensitivity 7 years later indirectly via increases in parents' secure base script knowledge.

Children with histories of secure attachments during infancy are expected to develop healthier patterns of physiological activity at rest and in response to a stressor than children with insecure attachments. The present study examined longitudinal associations between infant attachment security and children's respiratory sinus arrhythmia (RSA) at rest and in response to a frustration task at age 9. The study focused on a sample of children referred from Child Protective Services (N = 97). RSA reflects the regulation of the parasympathetic branch of the autonomic nervous system, is sensitive to environmental influences, and is associated with emotion regulation. Children with histories of secure attachments during infancy exhibited less RSA withdrawal during a frustration task than children with histories of insecure attachments. Attachment security was not significantly associated with baseline RSA. Results suggest that mitigating parasympathetic reactivity during frustrating situations may be one avenue by which infant attachment security promotes emotion regulation.

BACKGROUND: Interventions have been developed to promote the development of secure and organized attachments during early childhood among children who have experienced early adversity, yet little is known about whether the effects of these early interventions are sustained beyond 12 months postintervention. The current study examined whether receiving the Attachment and Biobehavioral Catch-Up (ABC) intervention during infancy led to improvements in perceived attachment security in middle childhood among 100 Child Protective Services (CPS)-referred children. METHODS: Children and parents were randomized to receive ABC or a control intervention during infancy. Children completed the Kerns Security Scale at age nine (Mage = 9.46, SD = 0.36). (Trial Registry Name: Intervening Early with Neglected Children; Registry ID: NCT02093052; URL for registry: https://clinicaltrials.gov/ct2/show/NCT02093052?term=dozier&rank=1). RESULTS: Children whose parents received ABC reported higher levels of attachment security on the Kerns Security Scale at age nine than children whose parents had received the control intervention, t(98) = 2.31, p = .023, d = 0.49. CONCLUSIONS: Findings underscore the long-term benefits of intervening early to promote caregiving quality among at-risk families and demonstrate the efficacy of a brief 10-session intervention in promoting attachment security over the span of eight years in a sample of CPS-referred children.

This study examined infant attachment as a predictor of social information processing (SIP) in middle childhood (n = 82) while controlling for parental sensitivity in middle childhood. 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.

The current longitudinal study examined whether attachment states of mind and childhood maltreatment predict sensitive caregiving during infancy, early childhood, and middle childhood among a sample of 178 parents who were involved with Child Protective Services. Nearly all the parents had themselves experienced childhood maltreatment based on their reports on the Childhood Trauma Questionnaire-Short Form (Bernstein et al., 2003) when their children were infants. Adult Attachment Interviews (George, Kaplan, & Main, 1985) were administered to parents when their children were infants (M = 10.92 months, SD = 8.66). Parental sensitivity was rated based on observations of parent-child interactions at three time points: infancy, early childhood, and middle childhood. During infancy, dismissing states of mind of parents predicted marginally lower sensitivity scores than autonomous states of mind. In early and middle childhood, dismissing states of mind of parents predicted significantly lower sensitivity ratings than autonomous states of mind. Unresolved states of mind of parents predicted significantly lower sensitivity scores than autonomous states of mind only during early childhood. Childhood maltreatment was not significantly associated with parents' sensitivity ratings at all three time points. Findings suggest that among parents with Child Protective Services involvement, most of whom had themselves experienced maltreatment, parents' unresolved states of mind predict insensitive caregiving in early childhood, and parents' dismissing states of mind predict insensitive caregiving from infancy through middle childhood.

Although children display strong individual differences in emotion expression, they also engage in emotional synchrony or reciprocity with interaction partners. To understand this paradox between trait-like and dyadic influences, the goal of the current study was to investigate children's emotion expression using a Social Relations Model (SRM) approach. Playgroups consisting typically of four same-sex unfamiliar nine-year-old children (N = 202) interacted in a round-robin format (6 dyads per group). Each dyad completed two 5-minute tasks, a challenging frustration task and a cooperative planning task. Observers coded children's emotions during the tasks (happy, sad, angry, anxious, neutral) on a second-by-second basis. SRM analyses provided substantial evidence of both the trait-like nature of children's emotion expression (through significant effects for actor variance, multivariate actor-actor correlations, and multivariate intrapersonal correlations) and the dyadic nature of their emotion expression (through significant effects for partner variance, relationship variance, dyadic reciprocity correlations, and multivariate interpersonal correlations).
RESUMEN
OBJECTIVE: To identify traumatic stress symptoms among expectant parents with a confirmed congenital anomaly and describe the ways in which a maternal-fetal care center, with an embedded multidisciplinary psychosocial support team, provides specific trauma-informed strategies to mitigate psychological distress from the first patient contact throughout prenatal care practice. METHOD: Traumatic stress symptoms in response to the confirmed congenital anomaly were assessed using the Impact of Events Scale-Revised. With Institutional Review Board approval, a total of 4,391 pregnant parents and 3,570 partners were analyzed based on routine universal screening performed in a single maternal-fetal care center. Exploratory, descriptive analyses examined rates of overall traumatic stress symptoms and subscale scores. RESULTS: 28.7% of pregnant parents and 24.2% of expectant partners reported elevated traumatic stress symptoms in response to their confirmed congenital anomaly, with clinically significant risk endorsed among 16.2% and 13.4%, respectively. Symptoms of intrusion and avoidance were most notable among parents. Methods of trauma-informed care provided by the multidisciplinary care team in collaboration with the psychosocial support team to identify, support, and intervene with high-risk parents are described. CONCLUSIONS: Recognizing that expectant parents who receive a prenatal diagnosis of a congenital anomaly are at heightened risk for experiencing traumatic stress symptoms, multidisciplinary care teams should offer trauma-informed strategies and psychosocial support services, including parental mental health screening, psychosocial assessment, and clinical intervention, as part of routine prenatal care to reduce the negative effect of emotional distress in the expectant parents prior to birth.

RESUMEN
The goal of the current study was to investigate whether children's social information processing (SIP) predicts their conversations with peers, including both their remarks to peers and peers' remarks to them. When children (N = 156; 55% male; United States; Representation by Race: 60% African American, 18% Mixed race, 15% European American, 7% Other; Representation by Latino/a Ethnicity: 22% Latino/a, 78% Not Latino/a; Mincome = $39,419) were 8 years old, we assessed their aggressive and prosocial SIP using the Social Information Processing Application (SIP-AP). When children were 9 years old, they participated in playgroups typically consisting of four same-sex unfamiliar children who interacted in a round-robin format. Each dyad completed a five-minute frustration task and a five-minute planning task. Observers coded children's verbalizations into six prosocial categories (Suggest, Agree, Solicit Input, Ask, Encourage, State Personal) and four antisocial categories (Command, Disagree, Discourage, Aggress). Children with higher aggressive SIP made more antisocial and fewer prosocial statements, whereas children with higher prosocial SIP made more prosocial and fewer antisocial statements. Furthermore, children with higher aggressive SIP elicited more antisocial and fewer prosocial statements from peers, whereas children with higher prosocial SIP elicited more prosocial and fewer antisocial statements from peers. Children's antisocial and prosocial remarks mediated relations between their aggressive SIP and peers' subsequent antisocial and prosocial remarks. Findings are discussed in terms of: (a) the use of SIP to predict more subtle social behaviors in children's social interaction, and (b) cycles of social interactions that maintain and reinforce children's SIP patterns.

Attachment security has been linked to healthy socioemotional development, but less is known about how secure attachment in infancy relates to emotional functioning in middle childhood, particularly across multiple contexts. The present study examined associations between secure attachment in infancy and children's context-dependent emotion expression during a parent-child interaction at age 9 (N = 78) among families with Child Protective Services involvement (i.e., children at risk for emotion dysregulation). The results indicated that children classified as securely attached in infancy exhibited less task-incongruent affect (i.e., less positive affect during a distressing discussion, less negative affect during a positive discussion) and a greater decrease in negative affect from a distressing discussion to a positive discussion than children classified as insecurely attached. In addition, secure children were rated as more appropriate in their emotion expression than insecure children. The present study highlights attachment as a promising intervention target for children at risk for emotion dysregulation. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

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.

Early exposure to intimate partner violence (IPV) places children at risk for ongoing emotional difficulties, including problems with self-regulation and high levels of internalizing symptoms. However, the impact of IPV exposure on children's error monitoring remains unknown. The present study utilized electroencephalography (EEG) to examine the impact of exposure to IPV in infancy on error monitoring in middle childhood. Results indicated that parents' perpetration of IPV against their romantic partners when children were under 24 months of age predicted hypervigilant error monitoring in children at age 8 (N = 30, 16 female), as indexed by error-related neural activity (ERN and Pe difference amplitudes), above and beyond the effects of general adversity exposure and parental responsiveness. There was no association between partner perpetration of IPV and children's error monitoring. Results illustrate the harmful effects of early exposure to parent-perpetrated IPV on error monitoring and highlight the importance of targeting children's and parents' cognitive and emotional responses to error commission in psychotherapy.

The goals of the current study were to (a) replicate the factor structure of the Social Information Processing Application (SIP-AP), (b) evaluate the measurement invariance of the SIP-AP across genders, socioeconomic (SES) levels, and forms of aggression, and (c) assess the convergent validity of the SIP-AP through associations with aggression, social competence, and rule-breaking behavior. Participants were 189 racially/ethnically diverse children (53% male; Mage = 8.50 years) who completed the SIP-AP. Parents reported on children's aggression and social competence, children reported on their aggression, and we observed children's rule-breaking behavior. A five-factor model including Hostile Cue Interpretations, Aggressive Goals, Aggressive Responses, Aggressive Response Evaluations, and Prosocial SIP replicated in this sample. The model was invariant across genders, SES levels, and forms of aggression (physical, relational, covert, property destruction). Girls reported more Aggressive Goals than boys. Children from more economically disadvantaged families reported higher levels of Hostile Cue Interpretations, Aggressive Goals, and Aggressive Response Evaluations. Aggression was related to all SIP constructs in expected directions, social competence was negatively associated with Hostile Cue Interpretations, and rule-breaking behavior was positively linked to Aggressive Goals, Aggressive Responses, and Aggressive Response Evaluations. Results are discussed in terms of the psychometric strengths of the SIP-AP. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

IMPORTANCE: Parenting interventions have been found to normalize cortisol regulation among high-risk children early in development; it is important to investigate the sustainability of these effects and their mechanisms, given the maladaptive outcomes associated with cortisol dysregulation. OBJECTIVE: To determine whether the Attachment and Biobehavioral Catch-up (ABC) intervention, implemented in infancy, predicts cortisol regulation in middle childhood via changes in early parental sensitivity. DESIGN: Double blind randomized clinical trial design; started January 2006, the follow-up for this project concluded March 2016. SETTING: Parents of children under age 2 referred from child protective services agencies in a large, mid-Atlantic city. PARTICIPANTS: 103 parent-child dyads (45.6% female children) with histories of child protective services involvement, randomly assigned to receive ABC (n = 45) or a control intervention (n = 58); in infancy, the children's ages ranged from 1.60 to 25.30 months (M = 9.87 months); at the middle childhood follow-up, they ranged from 8.0 to 11.0 years old (M = 8.52 years). INTERVENTIONS: Both conditions included 10-week, in-home, manualized interventions. The experimental condition, ABC, has 3 primary targets for parents: increasing nurturance to child distress, increasing following the child's lead, and decreasing frightening behavior. The control intervention, Developmental Education for Families (DEF), is an adaptation of a program focused on enhancing cognitive and language development. MAIN OUTCOMES AND MEASURES: Parental sensitivity was coded from a semi-structured interaction task between the parent and child in early childhood. Middle childhood diurnal cortisol slopes were modeled by collecting salivary cortisol samples from children at wake-up and bedtime over the course of 3 consecutive days. RESULTS: ABC participation in infancy was associated with increased parental sensitivity post-intervention, ßâ¯=â¯0.28, pâ¯=â¯.004, and this increased sensitivity predicted steeper decline across the day in children's cortisol concentration in middle childhood, ßâ¯=â¯-.53, pâ¯=â¯.002. The indirect effect of ABC on cortisol regulation via sensitivity was significant, ßâ¯=â¯-0.15, pâ¯=â¯.038. CONCLUSIONS AND RELEVANCE: ABC has an indirect effect on middle childhood diurnal cortisol regulation via parental sensitivity; future research should seek to determine how this enhanced neurobiological regulation relates to children's behavioral, socioemotional, and psychological outcomes.

BACKGROUND: Previous studies have established links between poor sleep and negative developmental outcomes. However, it remains unclear whether young maltreated children demonstrate atypical sleep patterns and whether sleep duration is associated with emotional and behavioral problems. OBJECTIVE: Explore trajectories of sleep among Child Protective Services (CPS)-referred children and examine whether sleep duration is significantly associated with externalizing and internalizing symptoms, even when controlling for the home environment. PARTICIPANTS: Participants included 197 children (Mage at first assessment = 10.24 months, SD = 6.39) whose parents were referred to CPS due to allegations of maltreatment. METHODS: Parents completed sleep diaries for their children at up to five time-points and the preschool version of the Child Behavior Checklist (CBCL) when children were approximately 2 years of age (Mage = 26.40 months, SD = 3.36). The Home Observation for Measurement of the Environment Scale (HOME) assessed the quality of the early home environment. RESULTS: Results from latent growth curve modeling demonstrated that CPS-referred children significantly varied (B = 3.28, SE = 0.90, p < .001) in the amount they slept in a 24-hour period at baseline (i.e., 4.1 months of age), and the amount of total sleep in a 24-hour period significantly decreased across time (B1 = -0.03, SE = 0.01, p < .001). When controlling for characteristics of the home environment, total sleep in a 24-hour period at baseline significantly inversely predicted externalizing (B = -1.03, SE = 0.06, p < .001) and internalizing symptoms (B = -0.19, SE = 0.03, p < .001) in early childhood. CONCLUSIONS: This study is an important first step in exploring trajectories of sleep among CPS-referred children. Findings underscore sleep as a promising target for interventions aimed at promoting regulation and highlight the need for future research to examine sleep in maltreated children as a predictor of later developmental outcomes.

Children who experience maltreatment are more likely than nonmaltreated children to demonstrate deficits in early receptive language skills that negatively impact their later academic achievement, social competence, and behavioral adjustment. It remains unclear whether placement in foster care affects children's early receptive language skills. In the current study, we examined whether children with Child Protective Services (CPS) involvement who were in foster care ( n = 176) had more advanced receptive vocabulary than children with CPS involvement who resided with their birth parents ( n = 144). Results demonstrated that children in foster care had higher receptive vocabulary scores at ages 36 and 48 months than children who stayed with their birth parents. Group differences were not significant after controlling for caregiver education level, marital status, and household income. These findings suggest that placement in foster care may be associated with meaningful improvements in children's receptive vocabulary among children with experiences of CPS involvement, and birth parents might benefit from increased supports to promote parent-child interactions that facilitate language development.

The present study used a longitudinal randomized clinical trial to test whether an early intervention has causal effects on children's autonomic nervous system regulation. When children were infants, parents involved with Child Protective Services received Attachment and Biobehavioral Catch-up (ABC; N = 43), an intervention that promotes sensitive parenting, or a control intervention (N = 53). When children were 9 years old, children whose parents had received ABC exhibited higher respiratory sinus arrhythmia and lower heart rate at rest and during a parent-child interaction than children in the control group. Intervention effects were not detected for children's average skin conductance levels or for indices of autonomic reactivity. Results suggest that a parenting-focused early intervention impacted the development of children's autonomic regulation.

BACKGROUND: Growing work points to the negative impact of early adverse experiences on the developing brain. An outstanding question concerns the extent to which early intervention can normalize trajectories of brain development in at-risk children. We tested this within the context of a randomized clinical trial of an early parenting program, the Attachment and Biobehavioral Catch-up (ABC), delivered to parents and infants monitored for maltreatment by Child Protective Services. METHODS: Families participated in the randomized clinical trial when children were 2.5 years of age or younger. Parenting and home adversity was measured at baseline. Children were followed longitudinally, and resting brain activity was measured electrophysiologically (n = 106) when children reached 8 years of age. Spectral power was quantified and compared across children assigned to the experimental intervention (ABC), a control intervention, and a low-risk comparison group (n = 76) recruited at the follow-up assessment. RESULTS: Higher early home adversity was associated with electrophysiological profiles indicative of cortical delays/immaturity in middle childhood, based on relatively greater power in lower frequency bands (theta, 4-6 Hz, and low alpha, 6-9 Hz) and lower power in a higher frequency band (high alpha, 9-12 Hz). Children assigned to ABC showed relatively greater high-frequency power (beta, 12-20 Hz) than children assigned to the control intervention. Beta power in the ABC did not differ from that of the low-risk comparison group. CONCLUSIONS: Maltreatment risk and home adversity can affect indicators of middle childhood brain maturation. Early parenting programs can support more normative patterns of neural function during middle childhood.
