Is autonomic functioning distinctly associated with anxiety and unsociability in preschoolers?

There are many benefits of peer interactions for children's social, emotional, and cognitive development, and isolation from peers may have negative consequences for children. Although biological processes may underlie social withdrawal broadly, distinct patterns may be associated with withdrawal behaviors depending on their underlying motivation (e.g., shy versus disinterested). This study investigated the role of autonomic nervous system activity, as assessed via skin conductance level (SCL) and respiratory sinus arrhythmia (RSA) in predicting changes in unsociability (e.g., lack of interest in peers) and anxious-fearfulness (e.g., discomfort among peers). Data were collected using a community sample of 92 US preschool children (45.7% female; Mage = 45.51 months, SDage = 3.81 months) at two time points one year apart. Gender differences were also explored. Baseline physiology was assessed while viewing a neutral video clip, and reactivity was assessed while viewing social exclusion and post-aggression discussion videos. For all children, coinhibition (i.e., SCL inhibition accompanied by RSA inhibition) to the post-aggression discussion video and blunted SCL activation to the exclusion video were prospectively associated with higher levels of anxious-fearfulness one year later. For boys only, baseline reciprocal sympathetic activation (i.e., SCL activation and RSA inhibition) was prospectively related to higher levels of unsociability one year later. For girls only, RSA inhibition in response to the post-aggression discussion video was prospectively related to higher levels of unsociability one year later. Findings contribute to a growing literature on autonomic reactivity in preschoolers' adjustment and suggest possible differences in the physiological processes underlying unsociability and anxious-fearfulness.

The Paper Chase: A Team Science Training Exercise.

Over the past few decades of psychological research, there has been an important increase in both the application of multidisciplinary or collaborative science and in training and research that emphasizes social justice and cultural humility. In the current paper, we report on the use of the "Paper Chase" as a team science training and research experience that also facilitates cultural humility in research and when working in teams. The Paper Chase is a synchronous writing exercise originally conceptualized by a cohort of health service psychology interns to reduce lag time between manuscript writing and submission (Schaumberg et al., 2015). The Paper Chase involves a group of trainees coming together for a predetermined amount of time (e.g., 9 or more hours) with the aim of writing and submitting a full manuscript for publication. In the current paper, we extend a previous report on the Paper Chase by formally linking the training experience to the four phases of team science: development, conceptualization, implementation, and translation. We also discuss ways in which the Paper Chase as a training experience can promote cultural humility. Finally, we provide updated recommendations for successfully completing a Paper Chase project. Overall, the authors of this manuscript who were predoctoral psychology interns across two recent cohorts at one academic medical center reported positive experiences from the Paper Chase. In addition, the current study suggests the Paper Chase can be used as one activity that facilitates critical training in team science.

Prenatal tobacco, tobacco-cannabis coexposure, and child emotion regulation: The role of child autonomic functioning and sensitive parenting.

Prenatal tobacco exposure (PTE) and tobacco-cannabis coexposure (PTCE) co-occur with negative maternal emotional functioning (termed prenatal risks) and together increase risk for child regulatory problems at early school age (ESA). Little is known about developmental processes in early childhood that may mediate this association. We examined two hypothesized mediational processes linking prenatal risks to ESA emotion regulation (ER) and lability-negativity; parasympathetic functioning at toddler age and chronic risk reflected by continued postnatal maternal negative emotional functioning (i.e., depression, anger/hostility, and emotion dysregulation) and substance exposure. Congruent with differential susceptibility theory, we examined interactions between sensitive parenting and toddler parasympathetic functioning predicting ESA ER. Finally, we explored the role of child sex as a moderator. Mothers (N = 247; 53% male infants; 51% Black, 31% White, 19% Hispanic, and 8% other or mixed race) were recruited in the first trimester of pregnancy into one of three groups: PTE (n = 81), PTCE (n = 97), and no substance exposure (n = 69) matched on age and education. Substance exposure was assessed using multiple methods, maternal negative emotional functioning via self-reports, parenting with observations, and child ER using teacher, maternal, and lab assessor reports. Results supported a chronic risk pathway with less support for a parasympathetic pathway. Toddlers who demonstrated respiratory sinus arrhythmia withdrawal to frustration were susceptible to the positive context of sensitive parenting in predicting higher ER. Results emphasize the importance of chronicity of postnatal risks including substance exposure and evaluating the differential impact of positive environments for children with substance exposure.

Considerations and Determinants of Discharge Decisions among Prenatal Substance Exposed Infants.

Limited research has examined a comprehensive set of predictors when evaluating discharge placement decisions for infants exposed to substances prenatally. Using a previously validated medical record data extraction tool, the current study examined prenatal substance exposure, infant intervention (i.e., pharmacologic, or non-pharmacologic), and demographic factors (e.g., race and ethnicity and rurality) as predictors of associations with discharge placement in a sample from a resource-poor state (N = 136; 69.9% Non-Hispanic White). Latent class analysis (LCA) was used to examine whether different classes emerged and how classes were differentially related to discharge placement decisions. Logistic regressions were used to determine whether each predictor was uniquely associated with placement decisions. Results of the LCA yielded a two-class solution comprised of (1) a Low Withdrawal Risk class, characterized by prenatal exposure to substances with low risk for neonatal abstinence syndrome (NAS) and non-pharmacologic intervention, and (2) a High Withdrawal Risk class, characterized by a high risk of NAS and pharmacologic intervention. Classes were not related to discharge placement decisions. Logistic regressions demonstrated that meth/amphetamine use during pregnancy was associated with greater odds of out of home placement above other substance types. Future research should replicate and continue examining the clinical utility of these classes.

A social-ecological model of preschoolers' aggressive behavior: An exploratory analysis.

Understanding classroom-level correlates of preschool children's aggressive behavior is critical to identifying multiple avenues for intervention within schools. The present school-based study evaluated the reliability and validity of a classroom-level measure of physical and relational aggression and examined a social-ecological model to test whether individual variables (i.e., temperament), dyadic peer factors (i.e., peer victimization, the number of a child's play partners), and classroom-level aggression were associated with individual aggression. Observations of play partners and teacher reports of temperament (i.e., daring, prosociality, and negative emotionality), peer victimization (i.e., physical and relational victimization), and classroom aggression were collected in a sample of preschoolers (N = 307; Mage = 48.99 months, SD = 7.51). Observer reports of aggression were used to create aggression severity and directionality scores, reflecting the overall level of aggression a child displays and their propensity to use physical relative to relational aggression, respectively. There was evidence to support the reliability and validity of the classroom-level aggression measure providing initial support that this measure could be used by school psychologists. A multilevel regression model indicated that higher levels of negative emotionality, daring, and a greater number of play partners were associated with higher levels of aggression severity. Children in classrooms with more relational aggression were more likely to use relational instead of physical aggression. These findings demonstrate the importance for school psychologists to account for multiple levels of influence when examining preschoolers' aggression.

The COVID-19 pandemic and measurement of preschoolers' executive functions.

Given the far-reaching effects of the COVID-19 pandemic, it is important to investigate how executive function (EF) assessments were impacted by changes in measurement protocols, context, and timing due to the pandemic. The present study used data from two projects. The first project occurred prior to the pandemic (N = 244, 44.67% female; Mage = 44.27 months) with teacher ratings and objective EF measures collected in the spring of preschool, fall of prekindergarten (pre-K), and spring of pre-K. The second study was comprised of two cohorts, a transition cohort (i.e., Fall 2019 to Fall/Winter 2020) and a post-COVID lockdown cohort (i.e., Fall 2020 to Fall/Winter 2021). For both cohorts, data were collected in the fall of pre-K, spring of pre-K, and fall/winter of kindergarten (N = 130, 46.2% female, Mage = 44.84 months). Aims included: (1) evaluating the measurement characteristics of a virtual assessment of EF, (2) examining cohort differences in teacher and objective EF measures, (3) testing longitudinal mean-level change in EF, and (4) evaluating associations between COVID impact and change in EF. Teachers reported a marginal decrease in EF for the transition cohort and no change in the post-COVID cohort, whereas objective measurements demonstrated the expected increase in EF. Child and family COVID-19 impact emerged as risk factors for reduced EF for the transition cohort but not the post-COVID cohort. Overall, this study provides novel evidence that the timing and type of EF assessment differentially impacted estimates of children's EF.

A U.S. National Study of Family Resilience During the COVID-19 Pandemic.

The COVID-19 pandemic has significantly disrupted the lives of children and their caregivers. Recent research has examined the impact of the pandemic on child and caregiver functioning but there is a paucity of work examining the impact of the pandemic on the broader family system. The current study examined family resilience during the COVID-19 pandemic across three aims: Aim 1 tested whether meaning, control, and emotion systems form a unitary family adaption factor, Aim 2 evaluated a concurrent model of family resilience, and Aim 3 examined whether parent gender and vaccination status moderated paths in the final model. A nationally representative sample of U.S. parents (N = 796; 51.8% fathers, M age = 38.87 years, 60.3% Non-Hispanic White) completed a cross-sectional survey about themselves and one child (5-16 years old) between February-April 2021, including measures of COVID-19 family risk and protective factors, pre-existing family health vulnerabilities, race, COVID-19 stressors, and family adaptation. Confirmatory Factor Analysis demonstrated that the meaning (i.e., family making meaning of COVID-19), control (i.e., stability in routines), and emotional (i.e., family support) facets of family adaptation are unique but related. A path model revealed that there were concurrent effects from COVID-19 exposure, pre-existing vulnerabilities, and racial diversity status to the family protective, vulnerability, and adaptation variables. Additionally, parent COVID-19 vaccination status altered the association between pre-existing family health vulnerabilities and the family protective factor. Overall, results underscore the importance of examining pre-existing and concurrent risk and protective factors for family resilience during a stressful, global, and far-reaching event.

Testing an integrated dimensional model of adverse childhood experiences: Associations with COVID-19 outcomes.

BACKGROUND: Adverse childhood experiences (ACEs) are a salient risk factor for a myriad of negative outcomes. Extant theoretical and empirical models traditionally quantify the impact of ACEs using cumulative representations. Recent conceptualizations challenge this framework and theorize that the types of ACEs children are exposed to differentially impacts their future functioning. OBJECTIVE: The current study tested an integrated ACEs model using parent-report of child ACEs across four aims: (1) characterize heterogeneity in child ACEs using a latent class analysis (LCA); (2) examine mean level class differences in COVID specific and COVID non-specific environmental factors (i.e., COVID impact, ineffective parenting, effective parenting) and internalizing and externalizing problems during the COVID pandemic; (3) test interactions between COVID impact and ACEs classes in predicting outcomes, and (4) compare a cumulative risk approach to a class membership approach. PARTICIPANTS AND SETTING: A nationally representative sample of U.S. parents (N = 796; 51.8 % fathers, M age = 38.87 years, 60.3 % Non-Hispanic White) completed a cross-sectional survey about themselves and one child (5-16 years old) between February-April 2021. METHOD: Measures of child's ACEs history, COVID impact, effective and ineffective parenting, and children's internalizing and externalizing problems were completed by parents. RESULTS: A LCA demonstrated three distinct classes of ACEs reflecting low-risk, trauma-risk, and environmental-risk classes. In general, the trauma-risk class had more negative COVID-19 outcomes than the other classes (small to large effect sizes). CONCLUSIONS: The classes differentially related to outcomes, providing support for dimensions of ACEs and emphasizing the distinct types of ACEs.

Trajectories of physical and relational aggression across early childhood: Relations with peer risk factors.

The goal of the current study was to examine trajectories of relational and physical aggression in early childhood and evaluate peer predictors of these trajectories (i.e., peer rejection, relational victimization, and physical victimization). The study spanned three-time points (T1 in the spring, T2 in the fall, and T3 in the spring) in early childhood (N = 300; 44.0% girls; Mage = 44.70 months, SD = 4.38; 3.0% African American/Black, 7.6% Asian/Asian American/Pacific Islander, 1.0% Hispanic/Latinx, 11.3% multiracial, 62.1% White, and 15.0% missing/unknown). Observations of peer victimization and teacher report of peer rejection were collected at T1, and teacher report of aggression was collected at all time points. Results from piecewise latent growth models demonstrated that both forms of aggression decreased from T1 to T2 as children entered a new classroom and increased from T2 to T3 as they remained in that classroom. The increase in physical aggression from T2 to T3 was only significant for boys. Peer rejection at T1 emerged as a predictor of both intercepts and slopes from T1 to T2, and physical victimization predicted the physical aggression intercept and physical aggression slope from T1 to T2. Children high on these peer risk variables had higher initial levels of aggression, followed by a greater decrease in aggression from T1 to T2. Results underscore the importance of studying incremental change in aggression in early childhood and suggest that children who experience negative peer treatment have greater fluctuations in aggression over time.

The Role of Autonomic System Coordination in Relations Between Peer Factors and Aggressive Behavior in Early Childhood.

This study tested biological sensitivity to context theory in the peer context. Respiratory sinus arrythmia (RSA-R) and skin conductance level (SCL-R) reactivity to a peer stressor were collected for participants (N = 86; M age = 45.99 months old; 70.2% White) in the summer (Time 1). Children's peer risk (i.e., physical and relational victimization) and protective (i.e., received prosocial behavior) factors were examined in the fall (T2) and relational and physical aggression were measured at T2 and in the spring (T3). Interactions were tested in regression analyses. Interactions emerged between relational victimization, RSA-R, and SCL-R in the prediction of T3 relational aggression and between received prosocial behavior, RSA-R, and SCL-R in the prediction of T3 relational and physical aggression, respectively. There was a positive relation between T2 relational victimization and T3 relational aggression for children with a coactivation pattern (i.e., increased RSA and SCL activity to a bullying stressor) but no relation for any other physiological pattern. Conversely, there was a negative relation between T2 received prosocial behavior and both forms of aggression at T3 for children with a reciprocal pattern (i.e., increased RSA and decreased SCL or decreased RSA and increased SCL activity) but no protective benefit of received prosocial behavior on subsequent aggression for children with a coactivation pattern. For children with a coinhibition pattern (i.e., decreased RSA and SCL activity), received prosocial behavior was negatively related to subsequent physical but not relational aggression. In sum, a coactivation pattern in response to stress may represent a vulnerability factor.

The development of forms and functions of aggression during early childhood: A temperament-based approach.

This study used a short-term longitudinal design with theoretically derived preregistered hypotheses and analyses to examine the role of temperament in the development of forms (i.e., physical and relational) and functions (i.e., proactive and reactive) of aggressive behavior in early childhood (N = 300, M age = 44.70 months, SD = 4.38, 44% girls). Temperament was measured via behavioral reports of emotional dysregulation, fearlessness/daring, and rule internalization/empathy and, in a subsample that completed a physiological assessment, via skin conductance and respiratory sinus arrhythmia. Emotion dysregulation generally served as a risk factor for all subtypes of aggression, with evidence of stronger associations with reactive as compared to proactive functions of relational aggression for girls. Daring predicted increases in physical aggression, especially among boys, and rule internalization predicted decreases in relational aggression, especially among girls. Rule internalization mediated longitudinal associations between daring and proactive relational aggression for girls. Some evidence also emerged supporting associations between adaptive functioning (i.e., high empathy, high respiratory sinus arrhythmia) and proactive functions of aggression. Findings highlight distinct temperamental risk factors for physical versus relational aggression and provide partial support for gender-linked theories of the development of aggression.

Parenting and Adjustment Problems among Preschoolers during COVID-19.

A critical area of developmental science explores factors that confer risk or protection as young children and their families experience stressful circumstances related to sociohistorical events. This study contributes to this important area by assessing relations between family context and child adjustment as children transitioned from preschool to home learning during COVID-19, and whether children higher in stress levels, indexed by morning basal cortisol, were more strongly affected. Parents of 74 children (M age = 53.56 months, SD age = 3.68 months) completed reports spanning the home learning transition; children's pre-COVID-19 transition salivary cortisol levels were assessed. Path analyses were used to test the preregistered study aims. Significant interactions were decomposed using simple slopes and Preacher's Regions of Significance (ROS) method. Across the COVID-19 transition to home-based school, children with higher morning basal cortisol experienced the sharpest increase in anger when exposed to harsh/inconsistent parenting contexts. Importantly, these effects held when controlling for household chaos, socioeconomic resources, and supportive parenting. Parallel models with supportive parenting were also tested and are discussed. This study is one of the first to test and provide support for biological sensitivity to context theory within the context of a natural experiment like COVID-19.

Autonomic nervous system reactivity and preschoolers' social dominance.

The purpose of this study was to investigate the role of skin conductance level reactivity (SCLR) and respiratory sinus arrhythmia reactivity (RSAR) in preschoolers' social dominance, as well as potential gender differences in these associations. Reactivity was assessed in response to viewing videos of social exclusion and a post-aggression discussion. In a community sample of 94 preschool children followed over one calendar year, reactivity to the post-aggression discussion, but not exclusion, video was related to social dominance. Specifically, increased RSAR to the post-aggression discussion video was positively associated with concurrent social dominance for both boys and girls. Longitudinally, for boys only, coactivation (i.e., increases in SCLR accompanied by increases in RSAR) to the post-aggression discussion video, which may reflect dysregulated, emotionally labile reactions to stress, was associated with relatively low levels of social dominance across the course of the year. Overall, findings contribute to a growing literature documenting the role of autonomic reactivity in preschoolers' social adjustment and extend this work to their capacity to achieve and maintain socially dominant positions with peers.

Development of Bullying and Victimization: An Examination of Risk and Protective Factors in a High-Risk Sample.

This prospective longitudinal study from birth to late adolescence investigated how early risk predicted subsequent aggression in middle childhood and bullying perpetration, bullying victimization, and violence victimization in adolescence. In addition, the moderating role of protective factors (i.e., maternal sensitivity, positive peers, and school connectedness) on these associations were examined. Caregiver-infant dyads (N = 216; 72% Black/African American) were recruited as part of a longitudinal study on substance exposed youth. Data using multiple methods and informants (observations, interviews, caregiver, and child/youth self-reports) were collected from dyads in early childhood (EC, birth to 48 months), middle childhood (MC, i.e., 84 months), early adolescence (EA, M = 13.26 years, SD = .83) and later adolescence (LA, M = 15.08 years, SD = .83). A developmental cascading path model was tested. There were direct associations between EC maternal harsh parenting and aggression in MC. In turn, MC aggression was associated with higher violence victimization and bullying in EA. Finally, EA violence victimization was then associated with higher levels of bullying as well as victimization from bullying in LA. Consistent with predictions, there was also evidence that protective factors (i.e., maternal sensitivity and positive peers) moderated the impact of predictor variables on aggression and bullying outcomes. Specifically, maternal sensitivity moderated the link between EC and MC aggression, such that those with moderately high levels of maternal sensitivity showed a negative relation between EC and MC aggression, whereas those with low levels of maternal sensitivity showed continuity in aggression. Positive peer influence moderated the link between violence victimization in EA and bullying in LA, such that children high on both violence victimization and positive peers had the highest levels of bullying victimization.

Stress reactivity and social cognition in pure and co-occurring early childhood relational bullying and victimization.

This study tested the independent effects and interactions of sympathetic nervous system reactivity and hostile attribution biases (HAB) in predicting change in pure and co-occurring relational bullying and victimization experiences over one year. Co-occurring and pure relational bullying and victimization experiences were measured using a dimensional bifactor model, aiming to address methodological limitations of categorical approaches, using data from 300 preschoolers (Mage = 44.70 months, SD = 4.38). Factor scores were then saved and used in nested path analyses with a subset of participants (n = 81) to test main study hypotheses regarding effects of HAB and skin conductance level reactivity (SCL-R). Bifactor models provided good fit to the data at two independent time points. HAB and SCL-R interacted to predict increases in co-occurring relational bullying/victimization with evidence for over- and underarousal pathways.

Measurement of aggressive behavior in early childhood: A critical analysis using five informants.

Measurement of aggressive behavior in early childhood is unique given that relational aggression is just developing, physical aggression is still prevalent, and both forms of aggression are relatively overt or direct. The current study had three aims. The first aim was to examine the internal reliability, validity, and correspondence of five different assessments of aggressive behavior in early childhood: parent report, teacher report, observer report, child report, and naturalistic school-based observations. The second aim was to test a one- and two-factor model of early childhood aggression using confirmatory factor analysis. The final aim of the study was to investigate gender differences among different reports of aggression. Observations, teacher report, and observer (research assistant) report were collected in the children's school, and parent report and child report were collected in a lab session at one time point (N = 300; 56% male; Mage = 44.86 months, SD = 5.55). Observations were collected using a focal child sampling with continuous recording approach, and previously validated measures were used for the remaining four informants. Results demonstrated that all measures were reliable with the exception of child report of relational aggression, and there was small to strong correspondence among the various informants. In addition, a two-factor structure of aggression provided the best fit to the data, providing evidence for divergence among relational and physical aggression. Finally, there were robust gender differences in physical aggression, but gender differences in relational aggression varied by method. The implications of different types of measurement are discussed.

Pathways From Early Family Violence to Adolescent Reactive Aggression and Violence Victimization.

PURPOSE: The current study examined how early childhood (EC) family violence and risk (i.e., maternal aggression, sibling aggression, environmental risk) predicted early adolescent (EA) reactive physical and relational aggression and violence victimization through middle childhood (MC) parenting (i.e., guilt induction, power assertive discipline). METHOD: Mother-infant dyads (N = 216; 72% African American) were recruited as part of a larger longitudinal study on prenatal cocaine and other substance exposure. Observations, interviews, and maternal and child self-report measures were collected from dyads in early childhood (1 to 36 months), middle childhood (84 months), and early adolescence (12 to 15 years). RESULTS: A cascading path model was specified where current variables were regressed on variables from the preceding time point. Primary results showed that environmental risk and EC child physical aggression predicted higher levels of MC caregiver power assertive discipline, which subsequently predicted lower levels of EA reactive relational aggression. Maternal substance use in pregnancy and the child's continuous placement with biological caregivers predicted higher levels of reactive physical aggression in EA. Finally, MC physical aggression and EA reactive relational aggression predicted higher levels of EA violence victimization. CONCLUSION: There were a series of direct paths from early childhood family violence and demographic factors to reactive aggression and violence victimization. The current study underscores the importance of evaluating multiple facets of family violence and risk when evaluating aggressive behavior and victimization.

Parsing apart affective dimensions of withdrawal: Longitudinal relations with peer victimization.

The current study examined a bifactor model of affective dimensions of withdrawal. Specifically, a model which specified a general factor of anxious-avoidant withdrawal (i.e., withdrawal with negative affect), a specific factor of unsociability (i.e., withdrawal without negative affect), and a specific factor of negative affect without withdrawal was specified in the primary sample (n = 238, 56.3% boys, M age = 44.92 months, SD = 5.32 months) and a validation sample (n = 332, 52.6% boys, M age = 47.11 months, SD = 7.32 months). The model provided a good fit to the data in both samples. In the primary sample, longitudinal relations between the bifactor model and peer victimization were examined across three time points (Time 1 in the spring, Time 2 in the fall, and Time 3 in the spring). Results showed that negative affect without withdrawal was concurrently associated with higher levels of relational and physical victimization at T1, unsociability predicted reductions in relational victimization from T1 to T2 as children entered a new classroom, and anxious-avoidant withdrawal predicted reductions in relational and physical victimization from T2 to T3 as children acclimated to the new classroom. Developmental considerations and clinical implications are discussed.

The Reciprocal Relations Between Female and Male Play Partners and Aggression in Early Childhood.

This study examined the relations between male and female play partners (PP) and relational (RA) and physical (PA) aggression in an early childhood short-term longitudinal study (N = 164, Mage  = 47.11 months, SD = 7.37 months). A cross-lagged path analysis was used to examine these relations from Time 1 (T1) to Time 2 (T2), 4 months after T1, and a multiple group analysis was tested across gender. Results showed that T1 male PP predicted an increase in PA, T1 RA predicted an increase in female PP, and T1 PA predicted a decrease in female PP. One path was not equivalent across gender. A post hoc interaction between male and female PP at T1 on future RA was evaluated.

Concurrent child history and contextual predictors of children's internalizing and externalizing behavior problems in foster care.

This study contributes to current research on the behavior problems of children in foster care by analyzing a more comprehensive set of concurrent child history and contextual predictors. Kinship home status and sibling status (i.e., whether the sibling was a biological sibling to the foster child) were evaluated as moderators of significant associations. Data were collected at the baseline of a foster parent training intervention program prior to any intervention services using parent phone interviews (N= 310, 51.6% male, M age = 7.57 years). Two linear hierarchical regressions were used to evaluate each set of predictors' association with behavior problems as well as each individual predictor's contribution. Results indicated that as a set, the contextual variables predicted a significant and unique amount of variability in the child's internalizing and externalizing behavior scores, but the child history variables did not. Specifically, the child's placement in a non-kinship home, being in a non-ethnically matched child-parent pair, higher parent stress scores, a greater number of prior group home placements, and higher internalizing behavior scores for the child predicted higher child externalizing scores. Higher parent stress scores, higher focal sibling externalizing behavior scores, and higher externalizing behavior scores for the child predicted higher internalizing scores for the child. The association between focal sibling externalizing behavior scores and child internalizing scores was moderated by kinship home status, such that there was a stronger association between the focal sibling's externalizing score and the child's internalizing score if the child was in a kinship compared to a non-kinship home. Implications for intervention services are discussed, particularly the importance of assessing the child's foster home environment when addressing the child's behavior problems.
