Negative family expressiveness and adolescents' externalizing problems: Respiratory sinus arrhythmia as a moderator and anger regulation as a mediator.

Family environment, emotion regulation and biological sensitivity have been shown to be associated with adolescents' externalizing problem behaviours. However, findings regarding respiratory sinus arrhythmia (RSA) reactivity are mixed and sometimes contradictory. This study aims to clarify the roles of RSA reactivity and anger regulation in the relationship between negative family expressiveness (NFE) and adolescents' externalizing behaviour by measuring RSA reactivity during the Parent-Adolescent Interaction Task (PAIT), designed to simulate a naturalistic negative family environment. In this study, 125 Chinese adolescents (M = 13.95 years, SD = 0.95; 48% male) completed questionnaires assessing negative family expressiveness, anger regulation and externalizing problems. Additionally, we collected electrocardiogram and respiration data during both the resting period and a 10-min PAIT. Results showed that anger regulation mediated the relationship between NFE and externalizing problem behaviours. Moreover, adolescents' RSA reactivity moderated this mediation effect, even after controlling for baseline RSA. Greater RSA suppression potentially indicated greater susceptibility, with the relationship between NFE and anger regulation being more pronounced in adolescents with greater RSA suppression compared to those with lesser RSA suppression. These findings highlight the importance of considering physiological systems, especially within the context of adverse family environments, when studying the relationships with externalizing problems.

Trajectories of polysubstance use: Are past-year internalizing and externalizing problems associated with trajectories of polysubstance use over time?

OBJECTIVE: Polysubstance use among adults has been a public health concern in the U.S. and is associated with adverse consequences. This study aimed to identify the longitudinal trajectory of polysubstance use and test whether internalizing and externalizing problems predict it. METHODS: Data of adults aged 18 and older (N = 15076) were extracted from the Waves 1-5 Population Assessment of Tobacco and Health Study (2013-2019). Group-Based Trajectory Modeling was performed to identify the trajectory of polysubstance use. Examined substances included use of cigarettes, e-cigarettes, excessive alcohol, cannabis, painkillers, and cocaine in past 30 days from all waves. Weighted multinomial logistic regressions were conducted to investigate the associations between internalizing and externalizing problems and the trajectory of polysubstance use, controlling for demographic variables. RESULTS: Five trajectory groups were identified: (1) No to minimal polysubstance use risk (45.6 %); (2) Polysubstance use-low risk (10.7 %); (3) Cigarette-leading polysubstance use-high risk (23.5 %); (4) Cigarette-cannabis co-leading polysubstance use-high risk (12.3 %); and (5) Cannabis-leading polysubstance use-high risk (7.8 %). Compared with Group 1, higher internalizing problems predicted the membership of Group 3 [Relative risk ratio (RRR) range: 1.07-1.17] and Group 4 (RRR range: 1.04-1.21). Compared with Group 1, higher externalizing problems predicted the membership of Group 5 (RRR range: 1.01-1.10). CONCLUSIONS: Prevention efforts should consider internalizing problems and associated trajectories of high-risk polysubstance use (e.g., cigarette-leading and cigarette-cannabis co-leading) as well as externalizing problems and associated trajectories of high-risk polysubstance use (e.g., cannabis-leading), when designing interventions to prevent polysubstance use.

Associations between bed-sharing in infancy and childhood internalizing and externalizing symptoms.

Bed-sharing is a controversial but common parenting practice with claimed benefits for emotional and behavioral development. Using data from the UK Millennium Cohort Study (N = 16,599), this prospective study investigated whether bed-sharing at 9 months is associated with childhood internalizing and externalizing symptom trajectories. Children were grouped by their patterns of co-developing internalizing and externalizing symptoms from 3 to 11 years of age using a parallel process latent class growth analysis. There were no associations between bed-sharing at 9 months of age and internalizing and externalizing symptom trajectories across childhood. This finding suggests that bed-sharing at 9 months has no positive or negative influence on the development of internalizing and externalizing symptoms across childhood. Clinicians should inform parents that bed-sharing during the second half of the first year is unlikely to have an impact on the later emotional and behavioral development of the children.

The Role of Anger Cognitions and Anger Rumination in Predicting Externalizing and Internalizing Problems in Adolescence.

This study aims to examine the relative contribution of anger cognitions and anger rumination in predicting externalizing and internalizing problems among 180 adolescents (aged 11-18 years) using correlational and linear regression analysis. Our findings showed that anger rumination predicted both externalizing (aggressive behaviors) and internalizing problems (anxious, depressive, and somatic symptoms). In contrast, biased anger cognitions did not appear to meaningfully predict either externalizing or internalizing symptoms, with the only exception of the hostile verbal labels and catastrophic cognitive attributions, a factor that was significantly associated with both rule-breaking behaviors (ß = .339, p < .01) and aggressive behaviors (ß = .238, p < .05). Anger rumination accounted for a higher rate of variance of psychopathology compared with anger cognitions and should be addressed in interventions for either externalizing or internalizing symptoms in adolescence.

Early Mother-Child Interaction Flexibility Predicts Adolescent Psychological Adjustment.

Although greater mother-child interaction flexibility has been linked with overall better adjustment within early childhood and adolescence, whether this link persists across the two developmental periods remains unknown. This longitudinal study examined mother-toddler flexibility in affective and behavioral exchanges as predictors of adolescents' externalizing and internalizing symptoms. Sample included 128 families with their 33-month-old toddlers (52% female), of whom 67 returned in adolescence (M age = 13.25 years, SD = 0.59). Greater affective flexibility during play and behavioral flexibility during snack predicted fewer parent-reported externalizing (but not internalizing) symptoms ten years later, controlling for the positivity-negativity of mother-toddler interactions, early-childhood adjustment, and mother-adolescent flexibility. The findings highlight the unique, prospective role of early-life caregiving flexibility in mitigating adolescents' behavioral problems.

Commercially Sexually Exploited Adolescent Girls: The Association Between Externalizing Disorders and Parental Incarceration with Suicide Attempts.

Commercial sexual exploitation (CSE) is a significant public health concern disproportionately affecting ethnoracially minoritized girls. Despite strong associations of CSE with suicide attempts, little is known about correlates of suicide among girls with CSE histories. Elevated rates of externalizing disorders (i.e., attention-deficit/hyperactivity disorder [ADHD], disruptive behavior disorders [DBD], conduct disorder [CD]) were observed among CSE youth, particularly in ethnoracially minoritized samples. Youth with CSE histories are frequently affected by parental incarceration, which is correlated with risk for suicide attempts. We tested cross-sectional simultaneous associations of externalizing disorders and parental incarceration with number of suicide attempts among 360 ethnoracially diverse girls affected by CSE (Mean age = 18.86). ADHD, DBD, and maternal incarceration were positively associated with number of suicide attempts. Findings implicate clinical/familial correlates of suicide attempts in this marginalized group, suggesting early suicide prevention efforts may improve traction on this problem by focusing on individual and family level factors.

Sensitivity to psychosocial influences at age 3 predicts mental health in middle childhood.

Children vary in how sensitive they are to experiences, with consequences for their developmental outcomes. In the current study, we investigated how behavioral sensitivity at age 3 years predicts mental health in middle childhood. Using a novel repeated measures design, we calculated child sensitivity to multiple psychological and social influences: parent praise, parent stress, child mood, and child sleep. We conceptualized sensitivity as the strength and direction of the relationship between psychosocial influences and child behavior, operationalized as toothbrushing time, at age 3 years. When children were 5-7 years old (n = 60), parents reported on children's internalizing and externalizing problems. Children who were more sensitive to their parents' praise at age 3 had fewer internalizing (r = -0.37, p = 0.016, pFDR = 0.042) and externalizing (r = -0.35, p = 0.021, pFDR = 0.042) problems in middle childhood. Higher average parent praise also marginally predicted fewer externalizing problems (r = -0.33, p = 0.006, pFDR = 0.057). Child sensitivity to mood predicted fewer internalizing (r = -0.32, p = 0.013, pFDR = 0.042) and externalizing (r = -0.38, p = 0.003, pFDR = 0.026) problems. By capturing variability in how children respond to daily fluctuations in their environment, we can contribute to the early prediction of mental health problems and improve access to early intervention services for children and families who need them most. RESEARCH HIGHLIGHTS: Children differ in how strongly their behavior depends on psychosocial factors including parent praise, child mood, child sleep, and parent stress. Children who are more sensitive to their parents' praise at age 3 have fewer internalizing and externalizing problems at age 5-7 years. Child sensitivity to mood also predicts fewer internalizing and externalizing problems.

Profiles of Family and School Experiences and Adjustment of Adolescents During the Transition to High School.

Although family and school experiences play an important role in adolescents' adjustment during the transition to high school, most prior studies investigated the effects of these experiences in isolation; their joint implications for both adolescents' concurrent and long-term adjustment outcomes are less clear, and the potential role of individual characteristics within such associations remains understudied. Based on 525 10th graders (Mage = 15.48, SDage = 0.71, 43.6% boys) who participated in a longitudinal study, the present research aimed to identify distinct family and school experience profiles among first-year high school students and examine their associations with adolescents' internalizing problems and externalizing problems, both concurrently and 18 months later. Latent profile analysis revealed four distinctive profiles: thriving, low resources-moderate family risk, developmental stress-high parental conflicts, and developmental stress-high peer victimization profiles. The other three profiles (vs. the thriving profile) reported significantly higher levels of concurrent internalizing problems; while these differences diminished after 18 months. However, the enduring impacts of these profiles on internalizing problems persisted among adolescents with higher levels of environmental sensitivity. Additionally, adolescents characterized by two developmental stress profiles (vs. the thriving profile) exhibited significantly higher levels of externalizing problems both currently and longitudinally. Findings underscore the importance of identifying at-risk populations among adolescents during the transition to high school by including both family and school experiences when examining environmental influence on their adjustment, as well as the necessity to take individual environmental sensitivity into account when examining these associations.

Functional Gastrointestinal Symptoms in Children with Autism and ADHD: Profiles of Hair and Salivary Cortisol, Serum Leptin Concentrations and Externalizing/Internalizing Problems.

BACKGROUND: Functional Gastrointestinal Disorders (FGIDs) present a higher prevalence in individuals with Neurodevelopmental Disorders (NDDs). The Stress System and the Gut-Brain axis (GBA) may mediate these relations. We aimed to assess the prevalence and profile of FGIDs in a clinical sample of children with Autism Spectrum Disorder (ASD) and Attention Deficit/Hyperactivity Disorder (ADHD) compared to typically developing children (TD) as well as to investigate possible relations between stress-related biomarkers and internalizing/externalizing problems in children with NDDS. METHODS: In total, 120 children, aged between 4 and 12 years old, formed three groups (N = 40, each): ADHD, ASD and TD. Salivary cortisol, hair cortisol and serum leptin were measured. RESULTS: The ASD group had more FGID problems than the TD group (p = 0.001). The ADHD and ASD groups had higher total internalizing/externalizing problems than the TD group (p < 0.0001, p < 0.0001, p = 0.005, respectively). Children with FGIDs showed more total, internalizing and externalizing problems compared to children without FGIDs (p < 0.0001, p < 0.0001, p = 0.041, respectively). The ADHD group showed lower AUCg values (p < 0.0001), while the hair cortisol was higher for the TD group (p < 0.0001). CONCLUSION: In conclusion, children with NDDs had more FGID symptoms and present higher internalizing and externalizing problems. Children with ADHD and FGIDs had more internalizing problems compared to those without FGIDs. No differences in stress-related biomarkers were shown to differentiate children with NDDs with and without FGIDs. Future prospective studies including a greater number of children may elucidate the biological pathways linking these comorbidities.

Family Functioning and Internalizing and Externalizing Problems in Gifted Children.

INTRODUCTION: Although gifted children can express high cognitive skills, they can also show socioemotional difficulties. Drawing from Olson's circumplex model, the present paper assessed the role of family functioning in internalizing and externalizing problems in gifted children. MATERIALS AND METHODS: 362 mothers and their 362 gifted children were included. The unbalanced subscales of the FACES IV-disengagement, enmeshment, rigidity, and chaos-and the CBCL were administered to mothers. The children completed the WISC-IV. RESULTS: The model predicting internalizing problems was significant and explained 5.6% of the variance. Only rigidity had an independent and positive effect on internalizing problems in gifted children over and above sociodemographic variables and QI, whereas disengagement, enmeshment, and chaos were not associated with internalizing problems. The model predicting externalizing problems was significant and explained 10% of the variance. Again, rigidity was the only variable that had an independent and positive effect on externalizing problems in gifted children over and above sociodemographic variables and QI, whereas disengagement, enmeshment, and chaos were not associated with externalizing problems in this population. DISCUSSION: Rigid families with a low ability to change in conditions that require readjustment appear to increase the risk of both internalizing and externalizing problems in gifted children. Although further studies are needed to support these preliminary findings, parental support interventions aimed at increasing flexibility appear to be useful.

The reflective function questionnaire for youth: Hungarian adaptation and evaluation of associations with quality of life and psychopathology.

An important correlate of mental health problems is mentalizing capacity, which appears to be particularly influential during adolescence. However, quality of life has not been studied in relation to mentalizing capacity among adolescents. This study aimed to translate the Reflective Function Questionnaire for Youth (RFQY) into Hungarian, present its psychometric properties, and assess its relationship with demographic characteristics, psychopathology and quality of life. A community sample of 384 youths aged 12-18 years completed the RFQY, the Measure of Quality of Life for Children and Adolescents, and the Strengths and Difficulties Questionnaire. First, we conducted an exploratory factor analysis with direct oblimin rotation on the RFQY items. Next, we assessed the associations between the RFQY and demographics, quality of life, and psychopathology. The EFA resulted in four factors: Internal-self, Internal-other, Self-other, and Strong emotions. The Cronbach's alpha coefficients of the scales were .81, .82, .67, and .80, respectively. The subscales were uniquely associated with psychopathology and quality of life. Our study provides the first psychometric support for the Hungarian version of the RFQY and indicates that adolescents suffering from internalizing, externalizing symptoms or lower levels of quality of life could benefit from interventions aimed at enhancing mentalizing capacity.

The Relation between Residential Mobility and Internalizing and Externalizing Problems in Adolescence: The Role of Subjective Moving Experience, Gender, and Friendship Quality.

Adolescent residential mobility can be a stressful life event, potentially aggravating internalizing or externalizing problems. However, the longitudinal effects of residential mobility are understudied and may be context-dependent. This study investigates the longitudinal associations between adolescent residential mobility and internalizing and externalizing problems. Additionally, this study examines for whom residential moves are most detrimental by including subjective moving experience, gender, and friendship quality before the move as moderators. Longitudinal data from 2,029 adolescents (51% female) from the TRacking Adolescents' Individual Lives Survey (TRAILS) were used (Mage [SD] at T1 = 11.1 [0.55], T2 = 13.6 [0.52], and T3 = 16.3 [0.70]). Results from stepwise multi-level random-effect models showed that adolescents who experienced an unpleasant move remained stable in internalizing problems, while others decreased over time. Adolescents who moved increased stronger in externalizing problems than adolescents who did not move, independent of whether they experienced the move as unpleasant. Gender and friendship quality before the move did not moderate the relation between residential mobility and internalizing or externalizing problem development. These results emphasize that residential moves in adolescence, especially when experienced as unpleasant, can have long-lasting negative effects on adolescent development.

The impact of excessive maternal weight on the risk of neuropsychiatric disorders in offspring-a narrative review of clinical studies.

The global prevalence of overweight and obesity is a significant public health concern that also largely affects women of childbearing age. Human epidemiological studies indicate that prenatal exposure to excessive maternal weight or excessive gestational weight gain is linked to various neurodevelopmental disorders in children, including attention deficit hyperactivity disorder, autism spectrum disorder, internalizing and externalizing problems, schizophrenia, and cognitive/intellectual impairment. Considering that inadequate maternal body mass can induce serious disorders in offspring, it is important to increase efforts to prevent such outcomes. In this paper, we review human studies linking excessive maternal weight and the occurrence of mental disorders in children.

The role of parental stress on emotional and behavioral problems in offspring: a systematic review with meta-analysis.

OBJECTIVE: Empirical evidence underscores an association between parental stress and emotional and behavioral problems in offspring. However, a comprehensive systematic review or meta-analysis on this topic is lacking. Thus, this study aims to address the scientific inquiry: Is there a relationship between parental stress and emotional/behavioral problems in children? SOURCES: This systematic review with a meta-analysis surveyed PubMed, PsycINFO, and the Biblioteca Virtual em Saúde between August and September 2021. The present search combined terms (school-age children) AND (parental stress OR parenting stress OR family stress) AND (emotional and behavioral problems OR internalizing and externalizing problems). Eligibility criteria encompassed cross-sectional, cohort, and case-control studies published within the last five years, exploring the association between parental stress (stressful life events and parenthood-related stress disorders) and emotional/behavioral problems in school-age children. PROSPERO ID CRD42022274034. SUMMARY OF THE FINDINGS: Of the 24 studies meeting all inclusion criteria (n = 31,183) for the systematic review, nine were eligible for inclusion in the meta-analysis. The meta-analysis revealed an association between parental stress and emotional problems (COR: 0.46 [95 % CI: 0.27 - 0.61], p < 0.001, Heterogeneity = 89 %) as well as behavioral problems (COR: 0.37 [95 % CI: 0.27 - 0.46], p < 0.001, Heterogeneity = 76 %). CONCLUSIONS: These findings indicate that parental stress predicts emotional/behavioral problems in school-age children. Since these problems are related to long-term negative effects in adulthood, these results are crucial for preventing mental health problems in offspring and for screening and managing parental stress.

Family dysfunction, stressful life events, and mental health problems across development in the offspring of parents with an affective disorder.

BACKGROUND: Offspring of parents with affective disorders (OAD) are at risk of developing a wide range of mental disorders. Deficits in the rearing environment and high levels of stress are well-known risk factors for negative outcomes in OAD. Building on prior research, we aim to examine the longitudinal relationships between family dysfunction, stressful life events, and mental health in OAD and control offspring of parents with no affective disorder. In the present study, we hypothesized that high levels of family dysfunction would be associated with more internalizing and externalizing problems across time in OAD than in controls, and that family dysfunction would mediate the relationship between stressful life events in adolescence and poor mental health in adulthood, particularly in OAD. METHODS: As part of the TRacking Adolescents' Lives Survey (TRAILS), 2230 participants (51% female, Mage = 11.1 years, SD = 0.6, at baseline) and their parents completed measures across six time points, spanning 15 years. Mental health, family dysfunction, and stressful life events were assessed with the Youth and Adult Self-Report, Family Assessment Device, and an in-house measure, respectively. RESULTS: Multi-group structured equation modeling revealed that family dysfunction was linked to internalizing and externalizing problems in OAD, but not controls, across time. Risk status did not moderate family dysfunction's mediation of the relationship between stressful life events and negative outcomes in adulthood. CONCLUSIONS: OAD show high sensitivity to dysfunction in the rearing environment across childhood and adolescence, which supports the use of family based interventions to prevent the development of mental disorders in high-risk youth.

Examining the relationship between meeting 24-hour movement behaviour guidelines and mental health in Chinese preschool children.

Background: Limited research has explored the relationship between adhering to 24-h Movement Behaviour guidelines and mental health in Chinese preschool children. The objectives of this study encompassed two primary goals: (1) to investigate the adherence of preschool children in China to the 24-h Movement Behaviour guidelines; and (2) to analyze the relationship between fulfilling various combinations of these guidelines and mental health, identifying the most advantageous combination. Methods: Utilizing a convenience sampling approach, this study included 205 preschool children (117 boys and 88 girls, average age 4.8 ± 0.51 years) from five kindergartens in Hengyang, Hunan Province. The physical activity (PA) and sedentary behaviour of preschool children were objectively assessed using waist-worn accelerometers, while sleep duration and screen time were reported by the children's parents. To evaluate mental health, the parent version of the internationally validated Strength and Difficulties Questionnaire (SDQ) was employed, which measures externalizing problems, internalizing problems, and prosocial behaviour. Employing Mplus 8.0 for Structural Equation Modeling analysis, while controlling for demographic variables, the study explored the connection between preschool children's mental health and their adherence to the 24-h Movement Behaviour guidelines. Results: Worryingly, merely 14.6% of preschoolers met the recommended guidelines for all three aspects (PA, sleep duration, and screen time). Positive correlations were identified between meeting PA guidelines and displaying prosocial behaviour (ß = 0.184; p < 0.05), while screen time adherence exhibited a negative correlation with externalizing problems (ß = -0.207; p < 0.05). Similarly, there was a negative association between sleep duration adherence and externalizing problems (ß = -0.191; p < 0.05). Meeting all three recommended guidelines was notably linked to enhanced prosocial behaviour (ß = 0.464; p < 0.05), while following the screen time and sleep duration guidelines was negatively associated with externalizing problems (ß = -0.246; p < 0.05). Conclusion: This study underscores the limited adherence of Chinese preschoolers to the comprehensive 24-h Movement Behaviour guidelines. Noteworthy findings include the positive influence of PA on prosocial behaviour, alongside the significant roles that sleep duration and screen time play in mitigating externalizing problems within this age group. Alignment with the 24-h Movement Behaviour guidelines is associated with more favorable mental health indicators in preschoolers.

Parental Migration Trajectories From Childhood Through Adolescence: Longitudinal Impact on Emotional and Behavioral Problems Among Chinese Adolescents.

It is estimated that there are about 23% of all children in China experiencing parental migration and being left behind at hometown. Existing research indicated a significant association between parental migration and children development but overlooked the dynamic changes in family structure caused by parental migration. In this study, data was derived from a nationally representative longitudinal survey-the China Family Panel Studies. The main analyses employed four waves of data (2012, 2014, 2016, and 2018) and included 1401 adolescents aged 10-15 years (Mean:12.35, SD:1.67; 54.2% female). Six typical trajectories of parental migration capturing both migration status at each timepoint and changes in the status across six years were created. Children's depression and internalizing problems and externalizing problems were concerned outcomes. The mediating roles of the caregiver-child interaction and caregiver's depression were examined. Adolescents in the trajectory group described as experiencing transitions between being left behind by both parents and non had a higher risk of depression and internalizing and externalizing problems. Caregivers' depression was a significant mediator between parental migration and adolescent depression.

Parenting and Emotional and Behavioral Difficulties in a General Population Sample of Adolescents: The Mediating Role of Emotional Dysregulation.

Research has shown that both parenting and emotional dysregulation are associated with mental health outcomes in youth. This cross-sectional research was developed to replicate these noted findings and explore the mediating role of emotional dysregulation to explain the relationship between parenting and emotional and behavioral difficulties (internalizing and externalizing problems) in adolescents. A total of 104 adolescents (61.5% females; M = 15.62 yrs., SD = 1.38) participated in the study. Participants completed the Parental Bonding Instrument (measuring care, promotion of autonomy, and overprotection) referring to both the mother and father, the Difficulties in Emotion Regulation Scale, and the Youth Self-Report. The results showed that difficulties in emotion regulation fully mediated the relationship between overprotection (in both parents) and low maternal care with internalizing problems, on the one hand, and the relationship between maternal overprotection and low care (in both parents) with externalizing problems, on the other hand. Furthermore, emotional dysregulation partially mediated the effect of paternal care on internalizing problems. These findings help to clarify one of the mechanisms through which parenting can affect mental health in youth. Theoretical and clinical implications are discussed.

Early executive functioning predicts externalizing problems in neurodiverse preschoolers.

Children with autism spectrum disorder (ASD) often exhibit externalizing problems, which have been linked with increased anxiety and depression, peer rejection, and parental stress. Identification of early predictors of externalizing behaviors in autism will facilitate identification of vulnerable children and implementation of early preventative interventions. There is ample evidence that executive functioning, social functioning, and temperament are predictive of later externalizing problems in general populations, but less is known about these relations in ASD and other neurodiverse populations, particularly in the early preschool years. To address this gap, we assessed the relations between executive functioning, social functioning, and temperament at age 3 and externalizing problems at age 5 in a sample of neurodiverse children with ASD and other neurodevelopmental disorders and delays. Analyses revealed that severity of early executive functioning impairment predicted increased externalizing problems. Severity of social autism symptoms moderated this relationship such that the effect of executive functioning on externalizing problems decreased as autism symptoms increased. These findings suggest that executive functioning is an important target for identifying and developing interventions for vulnerable children and underscore the necessity of considering severity of autism symptoms when researching the development of externalizing problems in children with neurodevelopmental disorders.

Age-dependent associations between RSA reactivity, affective and cognitive regulation, and psychopathology risk in young children exposed to varying levels of socioeconomic disadvantage.

This study examined autonomic nervous system activity (respiratory sinus arrhythmia [RSA]) as a biomarker of psychopathology in an ethnically and socioeconomically diverse sample (N = 57) of young children ages 4-7 years. RSA was measured at baseline and across four standardized tasks designed to assess self-regulation in both affective (i.e., "hot") and cognitive (i.e., "cool") contexts during early childhood. Our findings reveal that age moderated RSA activity, such that reduced RSA suppression was associated with a heightened risk of externalizing problems among older children during "cool" and "hot" contexts; for younger children, only RSA suppression during "hot" contexts predicted externalizing risk. The influence of socioeconomic disadvantage did not moderate the relationship between RSA and the risk of psychopathology, and there were minimal associations between RSA suppression and internalizing symptoms at this age range. These results suggest that autonomic variability may be a more effective predictor of psychopathology risk in older children, perhaps as they transition into formal schooling and face increasingly complex cognitive and social demands. Findings have implications for the identification of psychopathology in early developmental periods when regulation over emotions becomes essential for academic and social success.
