Parent‐child coregulation of parasympathetic processes varies by social context and risk for psychopathology

The parasympathetic nervous system supports social interaction and varies in relation to psychopathology. However, we know little about parasympathetic processes from a dyadic framework, nor in early childhood when parent‐child social interactions become more complex and child psychopathology first emerges. We hypothesized that higher risk for psychopathology (maternal psychopathology symptoms and child problem behavior) would be related to weaker concordance of respiratory sinus arrhythmia (RSA) between mothers and children (M = 3½ years old; N = 47) and that these relations could vary by social contextual demands, comparing unstructured free play, semistructured cleanup, and structured teaching tasks. Multilevel coupled autoregressive models of RSA during parent‐child interactions showed overall dynamic, positive concordance in mother‐child RSA over time, but this concordance was weaker during the more structured teaching task. In contrast, higher maternal psychological aggression and child externalizing and internalizing problems were associated with weaker dyadic RSA concordance, which was weakest during unstructured free play. Higher maternal depressive symptoms were related to disrupted individual mother and child RSA but not to RSA concordance. Thus, risk for psychopathology was generally related to weaker dyadic mother‐child RSA concordance in contexts with less complex structure or demands (free play, cleanup), as compared to the structured teaching task that showed weaker RSA concordance for all dyads. Implications for the meaning and utility of the construct of parent‐child physiological coregulation are discussed.     

The “Heart” of depression during early adolescence

This study examined the concurrent associations linking youths’ parasympathetic nervous system activity, specifically baseline respiratory sinus arrhythmia (RSA) and respiratory sinus arrhythmia reactivity (RSAR; vagal withdrawal), with youth depression risk in a community sample of young adolescents. Youth gender was examined as a moderator of associations. Participants included 100 youth (53% boys; M age = 11.05 years, SD = 0.33; 43% ethnic minorities), along with their mothers and teachers. Youth and mothers participated in a laboratory protocol involving a peer problem-solving conversation, during which youths’ physiological activity was measured. Youth reported on their depressive symptoms. Teachers reported on youth depression risk via internalizing symptoms and emotion regulation (e.g., emotion lability/negativity). Results from regression analyses revealed that youths’ vagal withdrawal during the mother-youth peer problem conversation was associated with lower youth-reported depressive symptoms. Further, gender moderated the associations linking youth baseline RSA and RSAR with youth depression risk. Specifically, among girls but not boys, higher baseline RSA was associated with lower depressive symptoms and emotion lability/negativity, and higher RSAR (i.e., vagal withdrawal) was linked with lower internalizing symptoms. Findings contribute to the relatively small literature linking youth parasympathetic functioning with depression risk, and point to specific implications for girls.     

Pathways from family economic conditions to adolescents' distress: Supportive parenting,stressors outside the family,and deviant peers

Economic hardship is a stressor that affects large numbers of children and their families. This study estimated a model that included pathways linking economic conditions to the internalizing and externalizing symptoms of a multiethnic sample of urban adolescents. Similar to other prominent models, this model included parental distress and parenting as key constructs, but the expanded ecological model also included stressors outside the family and adolescents' associations with deviant peers as possible explanatory factors. Data from 300 adolescents and their parents were consistent with a model that showed linkages between economic conditions, parental depressive symptoms, supportive parenting, and internalizing symptoms. Stressors outside the family were associated with deviant peer affiliations which, in turn, predicted internalizing and externalizing symptoms. The implications of these findings for understanding economic conditions' influence on adolescents' mental health are discussed. © 2002 John Wiley & Sons, Inc.     

The relations among depression in fathers, children's psychopathology, and father-child conflict: a meta-analysis

Research on parental depression is beginning to recognize the importance of studying fathers in relation to maladaptive outcomes in their offspring. Paternal depression is hypothesized to correlate with internalizing and externalizing psychopathology in children and adolescents and to compromise adaptive parent-child relationships (e.g., increased conflict). In the present paper, meta-analytic procedures were applied to this literature to address the magnitude and direction of covariation between paternal depression and children's functioning. In addition, we tested whether variation in findings could be accounted for by study characteristics. Results indicated that paternal depression was significantly related to offspring internalizing and externalizing psychopathology and father-child conflict. Larger effects for internalizing symptoms were associated with the use of community samples and symptom rating scales of internalizing problems.     

Adrenocortical activity in at-risk and normally developing adolescents: individual differences in salivary cortisol basal levels, diurnal variation, and responses to social challenges

The purpose of this study was to examine adrenocortical activity (basal, diurnal variation, and responses to social stressors) in adolescents at risk for psychopathology. Salivary cortisol levels were examined in normally developing and at-risk youth with internalizing and externalizing symptoms ranging from subclinical to clinical levels. Adolescents showed expected patterns of diurnal variation, with high early morning cortisol levels and a pattern of decline throughout the day. Females showed higher midday and late afternoon levels than males, and these patterns interacted with risk status. Internalizing problems sometimes were associated with gradual rather than steep declines in basal cortisol production. Both immediate and delayed cortisol reactivity to a social performance stressor were associated with internalizing symptoms. There was no evidence of relations between externalizing problems and underarousal of the hypothalamic-pituitary-adrenal (HPA) system. These and other results suggest that gender is an important moderating factor linking psychopathology. development, and context with HPA axis functioning in adolescence.     

Familial and temperamental predictors of resilience in children at risk for conduct disorder and depression

In this study, we evaluated predictors of resilience among 8- to 12-year-old children recruited from primarily low socioeconomic status neighborhoods, 117 of whom suffered from clinical levels of conduct problems and/or depression, and 63 of whom suffered from no significant symptoms. Tests of interactions were conducted between (a) paternal antisocial behavior and maternal depression and (b) several physiological indices of child temperament and emotionality in predicting (c) children's conduct problems and depression. Both internalizing and externalizing outcomes among children were associated specifically with maternal melancholic depression, and not with nonmelancholic depression. In addition, low levels of respiratory sinus arrhythmia (RSA) among children conferred significant risk for depression, regardless of maternal melancholia, whereas high RSA offered partial protection. Furthermore, high levels of maternal melancholia conferred significant risk for child depression, regardless of paternal antisocial behavior, whereas low levels of maternal melancholia offered partial protection. Finally, low levels of electrodermal responding (EDR) conferred significant risk for conduct problems, regardless of paternal antisocial behavior, whereas high EDR offered partial protection. None of the identified protective factors offered complete immunity from psychopathology. These findings underscore the complexity of resilience and resilience-related processes, and suggest several potential avenues for future longitudinal research.     

Exposure to Community Violence and the Trajectory of Internalizing and Externalizing Symptoms in a Sample of Low-Income Urban Youth

This study examined trajectories of psychopathology in a sample of low-income urban youth and tested exposure to community violence as a predictor of these trajectories. Self-report and parent-report survey measures of psychological problems and exposure to community violence were collected annually over 3 years from a sample of 364 fifth- to ninth-grade low-income urban youth (64% female; 95% youth of color). Linear growth models showed that youth experienced declines in both internalizing and externalizing symptoms across adolescence. Exposure to community violence was more strongly associated with externalizing symptoms than with internalizing symptoms but predicted declines in both types of symptoms. Results also indicated that youth reported more internalizing and externalizing symptoms than their parents reported for them. Exposure to community violence may explain unique trajectories of mental health problems among low-income urban youth. In addition, youth efforts to adopt a tough façade in the face of community violence could lead to higher rates of externalizing problems relative to internalizing problems, whereas desensitization processes may better explain reductions in both types of symptoms over time. Finally, youth report may be more valid than parent report in the context of urban poverty.     

THE RELATION BETWEEN RISK AND PROTECTIVE FACTORS FOR PROBLEM BEHAVIORS AND DEPRESSIVE SYMPTOMS,ANTISOCIAL BEHAVIOR,AND ALCOHOL USE IN ADOLESCENCE

Both externalizing and internalizing psychopathology increase throughout adolescence and a similar set of risk and protective factors may underlie depressive symptoms, antisocial behavior, and alcohol use. Analyses test how risk and protective factors for externalizing behavior in community, school, family, peer, and individual domains are related to depressive symptoms, antisocial behavior, and alcohol use concurrently and longitudinally in a sample of 2,002 students assessed in 8^th and 10^th grades (52% male; 58% Caucasian). Findings indicate that risk and protective factors for antisocial behavior and alcohol use are also associated with depressive symptoms, both concurrently and longitudinally. Prevention approaches that target risk and protective factors for externalizing problems may have crossover effects on depressive symptoms during adolescence.     

Parenting as a Moderator of the Effects of Maternal Depressive Symptoms on Preadolescent Adjustment

The purpose of this study was to examine whether parenting moderated the association between maternal depressive symptoms and initial levels and growth of preadolescent internalizing and externalizing symptoms. This study used a community sample of preadolescent children (N = 214; 8–12 years old at Time 1), measuring maternal depressive symptoms and parenting at Time 1, and preadolescent internalizing and externalizing symptoms at each year for 3 years. After modeling latent growth curves of internalizing and externalizing symptoms, growth factors were conditioned on maternal depressive symptoms, positive (acceptance and consistent discipline) and negative (rejection and physical punishment) parenting, and the interactions of depression and parenting. Maternal rejection moderated the relation of maternal depression with internalizing symptoms, such that high rejection exacerbated the effects of maternal depressive symptoms on initial levels of preadolescent internalizing problems. There were no significant interactions predicting externalizing problems. The findings highlight how specific parenting behaviors may alter the way in which maternal depressive symptoms confer risk for behavior problems.     

Biological, behavioral, and relational levels of resilience in the context of risk for early childhood behavior problems

Longitudinal growth patterns of internalizing and externalizing behavior problems were examined in a community sample of 441 children across the ages of 2 to 5 using hierarchical linear modeling. Contextual risk was measured using five indicators (socioeconomic status, marital status, number of siblings, parent stress, parent psychopathology), and three levels of child resilience (biological, behavioral, and relational) were also assessed. Results indicate that a general pattern of decline in both types of behavior problems was observed for the entire sample across time, although considerable individual variability in this pattern was observed. Children's externalizing and internalizing behavior at age 5 was predicted by the level of risk at age 2. All three child resilience factors were also predictive of externalizing and internalizing behaviors at age 5. In the prediction of the slope of problem behavior over time, risk status interacted with both temperamental fearlessness and a mutually responsive orientation with the mother to predict the decline in externalizing and internalizing problem behavior. Results underscore the complex interactions of risk and multiple levels of resilience that are implicated in the maintenance of problem behavior over time. They highlight the importance of considering whether expected resilience factors operate similarly across different levels of risk.     

From child maltreatment to adolescent cannabis abuse and dependence: a developmental cascade model

A developmental cascade model tested associations among child maltreatment, internalizing and externalizing psychopathology, social competence, and cannabis abuse and dependence symptoms in a longitudinal cohort (N = 415). Nested structural equation models evaluated continuity and cross-domain influences among broad multi-informant constructs across four developmental periods: age 7 to 9, 10 to 12, 13 to 15, and 15 to 18. Results indicated significant paths from child maltreatment to early externalizing and internalizing problems and social competence, as well as to cannabis abuse and dependence (CAD) symptoms in adolescence. Youth CAD symptoms were primarily related directly to child maltreatment and externalizing problems. Childhood internalizing symptoms contributed to later childhood decreases in social competence, which predicted increases in late adolescent externalizing problems. Using a developmental psychopathology framework, results are discussed in relation to cascade and transactional effects and the interplay between problem behaviors during childhood and development of CAD symptoms during early and late adolescence.     

Relations of Parenting to Adolescent Externalizing and Internalizing Distress Moderated by Perception of Neighborhood Danger

Parental monitoring and warmth have traditionally been studied in the context of White, middle-class families. This article explores optimal levels of these parenting behaviors in preventing adolescent psychopathology in impoverished, urban high-crime areas while accounting for child perceptions of neighborhood danger. In this study, data were collected longitudinally at 2 time points 1 year apart from a sample of 254 African American young adolescents (T1: M age = 12.6 years, 41% male) and their parents. Parental monitoring and warmth, child perception of neighborhood danger, and child internalizing and externalizing behaviors were measured using questionnaires. Child internalizing behaviors were also measured using a time sampling technique capturing in vivo accounts of daily distress. Findings indicated associations between parental monitoring and children's externalizing behaviors along with linear and quadratic associations between parental monitoring and internalizing behaviors. Monitoring and warmth were differentially related to symptoms depending on neighborhood danger level. When children perceived less danger, more monitoring related to less externalizing. When children perceived more danger, more warmth related to less internalizing. In addition, adolescents' perceptions of neighborhood danger emerged as equally strong as monitoring and warmth in predicting symptoms. This study underscores the influence of carefully considering parenting approaches and which techniques optimally prevent adolescents' externalizing, as well as prevent internalizing difficulties. It also highlights how context affects mental health, specifically how perceptions of danger negatively influence adolescents' psychopathology, emphasizing the importance of initiatives to reduce violence in communities.     

Peer victimization, psychosocial adjustment, and physical activity in overweight and at-risk-for-overweight youth

OBJECTIVE: To examine the relationship between peer victimization and child and parent reports of psychosocial adjustment and physical activity in a clinical sample of at-risk-for-overweight and overweight children and adolescents. METHODS: The Schwartz Peer Victimization Scale, Children's Depression Inventory-Short Form, Multidimensional Anxiety Scale for Children, Social Physique Anxiety Scale, PACE+ Adolescent Physical Activity Measure, and Asher Loneliness Scale were administered to 92 children and adolescents (54 females) aged 8-18 years. The youth's parent/guardian completed the Child Behavior Checklist. RESULTS: Peer victimization was positively related to child-reported depression, anxiety, social physique anxiety, and loneliness, and parent-reported internalizing and externalizing symptoms. Peer victimization was negatively related to physical activity. Depressive symptoms and loneliness mediated the relations between peer victimization and physical activity. CONCLUSION: Recognition of the magnitude of the problem and the means of evaluating for peer victimization is important for clinicians who work with overweight youth. Assessing peer experiences may assist in understanding rates of physical activity and/or past nonadherence to clinician recommendations.     

Heart period variability and psychopathology in urban boys at risk for delinquency

To examine associations between heart period variability (HPV) and psychopathology in young urban boys at risk for delinquency, a series of 69 7–11-year-old younger brothers of adjudicated delinquents received a standardized psychiatric evaluation and an assessment of heart period variability (HPV). Psychiatric symptoms were rated in two domains: externalizing and internalizing psychopathology. Continuous measures of both externalizing and internalizing psychopathology were associated with reductions in HPV components related to parasympathetic activity. These associations could not be explained by a number of potentially confounding variables, such as age, ethnicity, social class, body size, or family history of hypertension. Although familial hypertension predicted reduced HPV and externalizing psychopathology, associations between externalizing psychopathology and HPV were independent of familial hypertension. Psychiatric symptoms are associated with reduced HPV in young urban boys at risk for delinquency.     

Respiratory sinus arrhythmia reactivity across empirically based structural dimensions of psychopathology: A meta‐analysis

Low resting respiratory sinus arrhythmia (RSA) is observed in many mental health conditions, including anxiety disorders, mood disorders, schizophrenia spectrum disorders, disruptive behavior disorders, and nonsuicidal self‐injury, among others. Findings for RSA reactivity are more mixed. We evaluate associations between RSA reactivity and empirically derived structural categories of psychopathology—including internalizing, externalizing, and thought problems—among physically healthy adults. We searched multiple electronic databases for studies of RSA among participants who were assessed either dimensionally using well‐validated measures or diagnostically using structured interviews. Strict inclusion criteria were used to screen 3,605 published reports, which yielded 37 studies including 2,347 participants and 76 effect sizes. We performed a meta‐analysis, with meta‐analytic regressions of potential moderators, including psychopathology subtypes. The sample‐wide meta‐analytic association between RSA reactivity and psychopathology was quite small, but heterogeneity was considerable. Moderation analyses revealed significant RSA reactivity (withdrawal) specifically in externalizing samples. Additional moderators included (a) stimulus conditions used to elicit RSA reactivity (only negative emotion inductions were effective), (b) sex (women showed greater RSA reactivity than men), and (c) adherence to established methodological guidelines (e.g., higher electrocardiographic sampling rates yielded greater RSA reactivity). These findings indicate that associations between RSA reactivity and psychopathology are complex and suggest that future studies should include more standardized RSA assessments to increase external validity and decrease measurement error.     

Sleep problems,internalizing and externalizing symptoms,and domains of health-related quality of life: bidirectional associations from early childhood to early adolescence

Study ObjectivesTo examine longitudinal, bidirectional associations among behavioral sleep problems, internalizing and externalizing symptoms, and domains of health-related quality of life (HRQoL) from early childhood to adolescence in a population sample of Australian children.MethodData were drawn from the Longitudinal Study of Australian Children, a national prospective cohort study with 4983 children participating in the Kindergarten cohort. Data were collected when children were aged 4–5, 6–7, 8–9, 10–11, and 12–13 years. At each study wave, the primary parent (97% mothers) reported on behavioral child sleep problems, internalizing and externalizing symptoms, and HRQoL domains (psychosocial and physical). Cross-lagged structural equation models were used to evaluate bidirectional associations.ResultsAt nearly every age, behavioral sleep problems were associated with worse subsequent psychosocial and physical HRQoL. Despite bidirectional associations between mental health and HRQoL at many waves, HRQoL domains more strongly predicted later internalizing symptoms, while externalizing symptoms more strongly predicted later HRQoL. Many of the bidirectional associations among sleep, mental health, and HRQoL were found earlier in childhood.ConclusionsBehavioral sleep problems may forecast later HRQoL psychosocial and physical impairments. Attending to both sleep problems and HRQoL could prevent the progression of internalizing conditions, while a focus on externalizing concerns could prevent the worsening of these symptoms, sleep problems, and HRQoL, particularly during the transition to school.     

Life events, psychopathology, and suicidal behavior in Chinese adolescents

BACKGROUND: Little is known about risk factors of suicidal behavior among Chinese adolescents. This study examined the associations between negative life events, psychopathology, and suicidal behavior in rural adolescents of China. METHODS: A total of 1362 adolescent students in a rural prefecture of China completed a self-administered questionnaire concerning suicidal behavior, psychopathology, life events, and demographics. Data analyses were conducted using multivariate logistic regression modeling. RESULTS: Females were more likely to report suicidal ideation than males (22.0% vs. 17.5%). While the rate of suicide attempt was slightly higher in younger males (12-15 years) than in females (4.7% vs. 3.1%), the rate was higher in older females (16-18 years) than in males (12.7% vs. 9.5%). Suicide attempters reported more negative life events during the past year than suicidal ideators and non-suicidal adolescents. Academic stress and family conflicts were the major stress domains of adolescents at risk for suicidal behavior. A significant dose-response relationship was observed between the number of life events and suicidal behavior. Negative life events were also associated with increased risk for internalizing and externalizing problems. Both internalizing and externalizing problems were significantly associated with elevated risk for suicidal behavior after negative life events were controlled. LIMITATIONS: This is a cross-sectional study. Longitudinal study is warranted to examine the roles of life stress in adolescent suicidal behavior. CONCLUSIONS: Adolescents who experienced more negative life events are at increased risk for suicidal behavior. Both internalizing and externalizing problems mediate the effect of life events on adolescent suicidal behavior.     

Internalizing and externalizing problems in adolescence: general and dimension-specific effects of familial loadings and preadolescent temperament traits

BACKGROUND: We investigated the links between familial loading, preadolescent temperament, and internalizing and externalizing problems in adolescence, hereby distinguishing effects on maladjustment in general versus dimension-specific effects on either internalizing or externalizing problems.METHOD:In a population-based sample of 2230 preadolescents (10-11 years) familial loading (parental lifetime psychopathology) and offspring temperament were assessed at baseline by parent report, and offspring psychopathology at 2.5-years follow-up by self-report, teacher report and parent report. We used purified measures of temperament and psychopathology and partialled out shared variance between internalizing and externalizing problems.RESULTS:Familial loading of internalizing psychopathology predicted offspring internalizing but not externalizing problems, whereas familial loading of externalizing psychopathology predicted offspring externalizing but not internalizing problems. Both familial loadings were associated with Frustration, low Effortful Control, and Fear. Frustration acted as a general risk factor predicting severity of maladjustment; low Effortful Control and Fear acted as dimension-specific risk factors that predicted a particular type of psychopathology; whereas Shyness, High-Intensity Pleasure, and Affiliation acted as direction markers that steered the conditional probability of internalizing versus externalizing problems, in the event of maladjustment. Temperament traits mediated one-third of the association between familial loading and psychopathology. Findings were robust across different composite measures of psychopathology, and applied to girls as well as boys.CONCLUSIONS:With regard to familial loading and temperament, it is important to distinguish general risk factors (Frustration) from dimension-specific risk factors (familial loadings, Effortful Control, Fear), and direction markers that act as pathoplastic factors (Shyness, High-Intensity Pleasure, Affiliation) from both types of risk factors. About one-third of familial loading effects on psychopathology in early adolescence are mediated by temperament.     

Self- or parent report of (co-occurring) internalizing and externalizing problems,and basal or reactivity measures of HPA-axis functioning: A systematic evaluation of the internalizing-hyperresponsivity versus externalizing-hyporesponsivity HPA-axis hypothesis

Background

Previous research findings on the link between adolescents’ psychopathology and hypothalamic–pituitary–adrenal (HPA) axis activity have been heterogeneous.

Method

Adolescents (n = 211) with a preadolescent DSM-IV diagnosis participated in a lab-based social stress task. Saliva cortisol was assessed at awakening and during social stress. It was investigated if continuous measures of internalizing and externalizing problems and their interaction, using both self- and parent report, were associated with basal or reactivity measures of HPA-axis functioning

Results

During social stress, an enhanced total release of cortisol was associated with self-reported internalizing problems and a blunted total release of cortisol with self-reported externalizing problems. Post hoc analyses revealed that the association between enhanced cortisol output and internalizing problems held for boys but not for girls. Associations with morning cortisol measures were overall weak

Conclusions

Only in the context of stress, and particularly when based on self-report, blunted cortisol output was associated with externalizing and enhanced cortisol output with internalizing problems. Our broad approach demonstrates the importance of who reports on psychopathology, the use of dimensional measures of psychopathology, simultaneous analysis of internalizing and externalizing problems, and the use of awakening and social stress related measures of cortisol.     

Childhood psychiatric disorder and unintentional injury: findings from a national cohort study

OBJECTIVE: We set out to examine the relationship between unintentional injury and common child psychiatric disorders, including both internalizing and externalizing diagnoses. METHODS: The 1999 British Child and Adolescent Mental Health Survey provided a nationally representative sample of over 10,000 children aged 5-15 years. Measures included assessment of diagnoses of psychiatric disorder from the Diagnostic and Statistical Manual of Mental Disorders, fourth edition, unintentional injury, and a range of potentially related psychosocial factors. RESULTS: Children with psychiatric disorders had higher rates of unintentional injury. After accounting for psychosocial risk factors and comorbid psychopathology, oppositional defiant disorder (ODD) was independently associated with burns and poisoning. Attention deficit hyperactivity disorder (ADHD) was related to fractures, and depression and anxiety also showed independent links to some injury types. CONCLUSIONS: ODD and ADHD, rather than conduct disorder, appear to be the externalizing disorders associated with unintentional injury. We discuss possible models of the relationships between internalizing disorders and unintentional injury.
