Narrative Representations of Moral-Affiliative and Conflictual Themes and Behavioral Problems in Maltreated Preschoolers

Examined whether maltreated preschoolers are more likely than nonmaltreated preschoolers to have fewer moral-affiliative and more conflictual narrative representations and whether these representations mediate child behavior problems. A structured narrative story-telling task was administered to assess representations, and independent ratings of behavior problems were obtained from teachers. The narratives of maltreated children contained more conflictual and fewer moral-affiliative themes. Maltreated children also exhibited more internalizing and externalizing behavior problems. A partial mediation effect of conflictual representations on the relation between child maltreatment and externalizing behavior problems was found. The results demonstrate the relation between child maltreatment and children's organization of their life experiences and their behavioral symptomatology.     

The impact of child maltreatment and psychopathology on neuroendocrine functioning.

Cortisol regulation was investigated in a sample of school-aged maltreated (n = 167) and demographically comparable low-income nonmaltreated (n = 204) boys and girls in the context of a day camp research program. The presence of clinical-level internalizing and clinical-level externalizing symptomatology was determined through adult report and child self report. Children who exhibited clinical-level internalizing problems only, clinical-level externalizing problems only, and comorbid clinical-level internalizing and extemalizing problems were identified. Clinical-level cases were more prevalent among the maltreated children. Maltreated children with clinical-level internalizing problems were distinguished by higher morning, afternoon, and average daily cortisol levels across the week of camp attendance. In contrast, nonmaltreated boys with clinical-level externalizing problems emerged as distinct in terms of low levels of morning and average daily levels of cortisol. Maltreated children with comorbid clinical-level internalizing and externalizing problems were more likely not to show the expected diumal decrease in cortisol. The findings are discussed in terms of the joint impact of maltreatment and different forms of psychopathology on neuroendocrine regulation.     

Interactive effects of corticotropin releasing hormone receptor 1, serotonin transporter linked polymorphic region, and child maltreatment on diurnal cortisol regulation and internalizing symptomatology

Within an allostatic load framework, the effect of Gene × Environment (G × E) interactions on diurnal cortisol regulation and internalizing symptomatology were investigated. Variation in the corticotropin releasing hormone receptor 1 (CRHR1) TAT haplotype and serotonin transporter linked polymorphic region (5-HTTLPR) was determined in a sample of maltreated (n = 238, 21.4% with early physical and sexual abuse) and nonmaltreated (n = 255) children (M age = 10.08) participating in a summer research camp. Internalizing and depressive symptoms were assessed by other and self-report. G × E effects for CRHR1 and maltreatment and early abuse on diurnal cortisol regulation were observed; CRHR1 variation was related to cortisol dysregulation only among maltreated children. Early abuse and high internalizing symptoms also interacted to predict atypical diurnal cortisol regulation. The interaction of CRHR1, 5-HTTLPR, and child maltreatment (G × G × E) identified a subgroup of maltreated children with high internalizing symptoms who shared the same combination of the two genes. The findings support an allostatic load perspective on the effects of the chronic stress associated with child maltreatment on cortisol regulation and internalizing symptomatology as moderated by genetic variation.     

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.     

Child maltreatment and allostatic load: consequences for physical and mental health in children from low-income families

Child maltreatment and biomarkers of allostatic load were investigated in relation to child health problems and psychological symptomatology. Participants attended a summer research day camp and included 137 maltreated and 110 nonmaltreated low-income children, who were aged 8 to 10 years (M = 9.42) and racially and ethnically diverse; 52% were male. Measurements obtained included salivary cortisol and dehydroepiandosterone, body mass index, waist-hip ratio, and blood pressure; these indicators provided a composite index of allostatic load. Child self-report and camp adult-rater reports of child symptomatology were obtained; mothers provided information on health problems. The results indicated that higher allostatic load and child maltreatment status independently predicted poorer health outcomes and greater behavior problems. Moderation effects indicated that allostatic load was related to somatic complaints, attention problems, and thought problems only among maltreated children. Risks associated with high waist-hip ratio, low morning cortisol, and high morning dehydroepiandosterone also were related to depressive symptoms only for maltreated children. The results support an allostatic load conceptualization of the impact of high environmental stress and child abuse and neglect on child health and behavioral outcomes and have important implications for long-term physical and mental health.     

Parenting behavior dimensions and child psychopathology: specificity, task dependency, and interactive relations.

This study examined the specificity of relations between parent or caregiver behaviors and childhood internalizing and externalizing problems in a sample of 70 fourth-grade children (64% boys, M age = 9.7 years). Specificity was assessed via (a) unique effects, (b) differential effects, and (c) interactive effects. When measured as unique and differential effects, specificity was not found for warmth or psychological control but was found for caregiver's use of behavior control. Higher levels of behavior control were uniquely related to lower levels of externalizing problems and higher levels of internalizing problems; differential effects analyses indicated that higher levels of behavior control were related to decreases in the within-child difference in relative levels of level of internalizing versus externalizing problems. Interactive relations among the 3 parenting behavior dimensions also were identified. Although caregivers emphasized different parenting behavior dimensions across 2 separate caregiver-child interaction tasks, relations between parenting behavior dimensions and child psychopathology did not vary as a function of task. These findings indicate the importance of assessing and simultaneously analyzing multiple parenting behavior dimensions and multiple child psychopathology domains.     

The effects of child maltreatment on early signs of antisocial behavior: genetic moderation by tryptophan hydroxylase, serotonin transporter, and monoamine oxidase A genes

Gene-environment interaction effects in predicting antisocial behavior in late childhood were investigated among maltreated and nonmaltreated low-income children (N = 627, M age = 11.27). Variants in three genes were examined: tryptophan hydroxylase 1 (TPH1), serotonin transporter linked polymorphic region (5-HTTLPR), and monoamine oxidase A (MAOA) upstream variable number tandem repeat. In addition to child maltreatment status, we considered the impact of maltreatment subtypes, developmental timing of maltreatment, and chronicity. Indicators of antisocial behavior were obtained from self-, peer, and adult counselor reports. In a series of analyses of covariance, child maltreatment and its parameters demonstrated strong main effects on early antisocial behavior as assessed by all report forms. Genetic effects operated primarily in the context of gene-environment interactions, moderating the impact of child maltreatment on outcomes. Across the three genes, among nonmaltreated children no differences in antisocial behavior were found based on genetic variation. In contrast, among maltreated children specific polymorphisms of TPH1, 5-HTTLPR, and MAOA were each related to heightened self-report of antisocial behavior; the interaction of 5-HTTLPR and developmental timing of maltreatment also indicated more severe antisocial outcomes for children with early onset and recurrent maltreatment based on genotype. TPH1 and 5-HTTLPR interacted with maltreatment subtype to predict peer reports of antisocial behavior; genetic variation contributed to larger differences in antisocial behavior among abused children. The TPH1 and 5-HTTLPR polymorphisms also moderated the effects of maltreatment subtype on adult reports of antisocial behavior; again, the genetic effects were strongest for children who were abused. In addition, TPH1 moderated the effect of developmental timing of maltreatment and chronicity on adult reports of antisocial behavior. The findings elucidate how genetic variation contributes to identifying which maltreated children are most vulnerable to antisocial development.     

The timing of child physical maltreatment: a cross-domain growth analysis of impact on adolescent externalizing and internalizing problems.

In a sample of 578 children assessed in kindergarten through the eighth grade, we used growth modeling to determine the basic developmental trajectories of mother-reported and teacher-reported externalizing and internalizing behaviors for three physical maltreatment groups of children-early-harmed (prior to age 5 years), later-harmed (age 5 years and over), and nonharmed--controlling for SES and gender. Results demonstrated that the earlier children experienced harsh physical treatment by significant adults, the more likely they were to experience adjustment problems in early adolescence. Over multiple domains, early physical maltreatment was related to more negative sequelae than the same type of maltreatment occurring at later periods. In addition, the fitted growth models revealed that the early-harmed group exhibited someswhat higher initial levels of teacher-reported externalizing problems in kindergarten and significantly different rates of change in these problem behaviors than other children, as reported by mothers over the 9 years of this study. The early-harmed children were also seen by teachers, in kindergarten, as exhibiting higher levels of internalizing behaviors. The later-harmed children were seen by their teachers as increasing their externalizing problem behaviors more rapidly over the 9 years than did the early- or nonharmed children. These findings indicate that the timing of maltreatment is a salient factor in examining the developmental effects of physical harm.     

Effect of Co-Occurrence on the Referability of Internalizing and Externalizing Problem Behavior in Adolescents

Assessed the effect of co-occurring versus not co-occurring internalizing and externalizing behavior problems on the reasons parents reported for clinical referral of their adolescent child. Reasons for referral were coded for 181 inpatient adolescents, and parent ratings of internalizing and externalizing behavior were obtained for a general population sample of 500 adolescents. Parents concurrently reported internalizing and externalizing behavior as reasons for referral less frequently (p < .0001) than would be expected given the correlation between these two domains in the general population sample. This suggests that the presence of externalizing problems may decrease parents' concern or awareness of internalizing problems, the presence of internalizing problems may decrease parents' concern or awareness of externalizing problems, or both Implications for the clinical referral of adolescents and for informal parental efforts at helping their children with externalizing and internalizing problems are discussed.     

Children's affect regulation during a disappointment: psychophysiological responses and relation to parent history of depression

Psychophysiological responses during affect regulation were examined in 57 children ages 3-9 years, 41 of whom had a parent history of childhood-onset depression (COD). During a structured laboratory task, children were given first a disappointing toy and then a desired toy. Frontal electroencephalogram (EEG) asymmetry, respiratory sinus arrhythmia (RSA), heart period, and heart period variability were measured during resting and task conditions. Affective and self-regulatory behaviors were coded from videotape. In 3-5-year olds, greater relative right frontal activity was associated with withdrawal behavior. High heart period was associated with approach behavior. Compared with children of psychiatrically healthy parents, children of parents with COD exhibited poor heart period recovery after disappointment. For children of parents with COD, greater relative left frontal activity was related to concurrent internalizing and externalizing problems, and low resting RSA was related to internalizing problems. Physiological responses associated with affect regulation may help identify children at risk for depression.     

Psychological Evaluation of Exceptional Children (Book)

Examined stability and predictability of externalizing behavior problems in 77 boys and girls from preschool to first grade. There was a moderate degree of stability in teacher and mother ratings of child externalizing behavior and child IQ from pre-school to first grade, with no sex difference. When children were classified into pervasive externalizing, borderline externalizing, or comparison groups, there was very high stability of group status. Preschool measures explained 45% of the variance in first-grade teacher ratings of externalizing behavior. Child IQ at preschool was not predictive. Teacher-identified externalizing problems for first graders were predicted not only from preschool child externalizing behavior, but also from preschool-assessed mother's authoritarian childrearing practices and mother's parenting stress. Similar findings emerged when predicting mother ratings. A discriminant analysis utilizing these preschool variables predicted group membership at first grade for 95% of the cases in the pervasive externalizing and comparison groups. Implications for parent-focused intervention are discussed.     

Efficacy of a home-visiting intervention aimed at improving maternal sensitivity, child attachment, and behavioral outcomes for maltreated children: a randomized control trial

The efficacy of a short-term attachment-based intervention for changing risk outcomes for children of maltreating families was examined using a randomized control trial. Sixty-seven primary caregivers reported for maltreatment and their children (1-5 years) were randomly assigned to an intervention or control group. The intervention group received 8 weekly home visits directed at the caregiver-child dyad and focused on improving caregiver sensitivity. Intervention sessions included brief discussions of attachment-emotion regulation-related themes and video feedback of parent-child interaction. Comparison of pre- and posttest scores revealed significant improvements for the intervention group in parental sensitivity and child attachment security, and a reduction in child disorganization. Older children in the intervention group also showed lower levels of internalizing and externalizing problems following intervention. This is the first study to demonstrate the efficacy of short-term attachment-based intervention in enhancing parental sensitivity, improving child security, and reducing disorganization for children in the early childhood period.     

The relation between common sleep problems and emotional and behavioral problems among 2- and 3-year-olds in the context of known risk factors for psychopathology

The contribution of sleep problems to emotional and behavioral problems among young children within the context of known risk factors for psychopathology was examined. Data on 2- and 3-year-olds, representative of Canadian children without a chronic illness, from three cross-sectional cohorts of the Canadian National Longitudinal Study of Child and Youth were analysed ( n  = 2996, 2822, and 3050). The person most knowledgeable (PMK), usually the mother, provided information about her child, herself, and her family. Predictors included: child health status and temperament; parenting and PMK depressive symptomatology; family demographics (e.g., marital status, income) and functioning. Child sleep problems included night waking and bedtime resistance. Both internalizing/emotional (i.e., anxiety) and externalizing/behavioral problems (i.e., hyperactivity, aggression) were examined. Adjusting for other known risk factors, child sleep problems accounted for a small, but significant, independent proportion of the variance in internalizing and externalizing problems. Structural equation models examining the pathways linking risk factors to sleep problems and emotional and behavioral problems were a good fit of the data. Results were replicated on two additional cross-sectional samples. The relation between sleep problems and emotional and behavioral problems is independent of other commonly identified risk factors. Among young children, sleep problems are as strong a correlate of child emotional and behavioral problems as PMK depressive symptomatology, a well-established risk factor for child psychopathology. Adverse parenting and PMK symptomatology, along with difficult temperament all contribute to both sleep problems and emotional and behavioral problems. Children's sleep problems appear to exacerbate emotional and behavioral problems.     

A preliminary study of cortisol reactivity and behavior problems in young children born premature

The purpose of the present study was to examine the relation between cortisol reactivity and comorbid internalizing and externalizing behavior problems among children born premature. Children between the ages of 18 and 60 months who were born <37 weeks gestation and presented with clinically significant externalizing behavior problems were included. Children were categorized based on those who mounted a cortisol response to a stressor and those who did not mount a cortisol response. Children demonstrating the cortisol response were reported to have more problems with attention, emotional reactivity, anxiety, and depression based on maternal report and displayed higher rates of negative verbalizations during a mother–child interaction than children without a cortisol response. These results extend the findings of the relation between cortisol reactivity and comorbid internalizing and externalizing behavior problems to a sample of children born premature. © 2010 Wiley Periodicals, Inc.

Multiple maltreatment, attribution of blame, and adjustment among adolescents.

The study examined the predictive utility of blame attributions for maltreatment. Integrating theory and research on blame attribution, it was predicted that self-blame would mediate or moderate internalizing problems, whereas other-blame would mediate or moderate externalizing problems. Mediator and moderator models were tested separately. Adolescents (N = 160, ages 11-17 years) were randomly selected from the open caseload of a child protection agency. Participants made global maltreatment severity ratings for each of physical abuse, psychological abuse, neglect. sexual abuse, and exposure to family violence. Participants also completed the Attribution for Maltreatment Interview (AFMI), a structured clinical interview that assessed self- and perpetrator blame for each type of maltreatment they experienced. The AFMI yielded five subscales: self-blaming cognition, self-blaming affect, self-excusing. perpetrator blame, and perpetrator excusing. Caretaker-reported (Child Behavior Checklist) and self-reported (Youth Self Report) internalizing and externalizing were the adjustment criteria. Controlling for maltreatment severity, the AFMI subscales explained significant variance in self-reported adjustment. Self-blaming affect was the most potent attribution, particularly among females. Attributions mediated maltreatment severity for self-reported adjustment but moderated it for caretaker-reported adjustment. The sophistication and relevance of blame attributions to adjustment are discussed, and implications for research and clinical practice are identified.     

Developmental psychopathology and the reciprocal patterning of behavior and environment: distinctive situational and behavioral signatures of internalizing, externalizing, and mixed-syndrome children

In contrast to assessment approaches that conceptualize traits as generalized response tendencies, this research develops a conditional approach that conceptualizes traits as patterns of relations between contexts and behaviors. Using extensive observations of social interactions, this study investigated internalizing, externalizing, and mixed-syndrome children identified by T. M. Achenbach's (1993) measures. Children in these groups differed in the patterning of their responses to social contexts and in the likelihood of encountering them. Mixed-syndrome children showed a distinctive behavior pattern consisting of aggressive and withdrawn responses to nonaversive contexts. The results demonstrate how measures of overall tendencies confound person and environment influences and obscure differences between children that are revealed by contextualized measures. The need to incorporate contexts more fully into clinical assessment is discussed.     

A Step Beyond Maternal Depression and Child Behavior Problems: The Role of Mother–Child Aggression

Previous researchers have identified problematic mother–child interaction patterns as a potential pathway through which maternal depressive symptoms impact child behavior problems, but could not establish the temporal precedence of these associations. This longitudinal study investigated mother–child aggression as a mechanism in the association between maternal depressive symptoms that occurred during infancy and subsequent child behavior problems among high-risk families. Two hundred thirty-four socioeconomically disadvantaged families were recruited from neighborhoods with high rates of family violence. During infancy (12–18 months), early childhood (4 years), and middle childhood (6 years), mothers reported their current depressive symptoms and use of psychological and physical aggression with their child. During early and middle childhood, mothers reported their children’s behavior problems. Using path analyses, a temporal process was identified in which mother–child aggression during early childhood mediated the association between maternal depressive symptoms during infancy and higher levels of externalizing behavior problems during middle childhood. Mother–-child aggression did not mediate the association between maternal depressive symptoms during infancy and higher levels of internalizing behavior problems during middle childhood. Early maternal depressive symptoms that occur during infancy are important risk factors for subsequent mother–child aggression, which, in turn, contributes to more child externalizing behavior problems. Therefore, screening mothers for depressive symptoms and providing intervention and prevention services to improve mother–child interactions may be crucial to preventing the exacerbation of externalizing behavior problems. Additional research is needed to identify pathways to child internalizing behavior problems.     

Changes in women's alcoholic, antisocial, and depressive symptomatology over 12 years: a multilevel network of individual, familial, and neighborhood influences

In a sample of 273 adult women and their families, we examined the effects of women's psychopathology history, their social support, their husbands' and children's symptomatology, family stress, and neighborhood environment on their alcohol problems, antisocial behavior, and depression over a 12-year period during their 30s and early 40s. Women's alcohol problems and antisocial behavior decreased but their depression symptoms increased over time. Women's disorder history and their partners' parallel symptomatology were associated with their symptoms. For women's antisocial behavior, their own history of alcoholism and their partners' alcohol problems were also significant risk factors. Higher levels of social support were associated with lower levels of depression in women. Children's externalizing behavior was positively correlated with their mothers' alcohol problems and antisocial behavior, whereas children's internalizing behavior was positively correlated with their mothers' depression. Neighborhood residential instability was associated with higher levels of alcoholic and depressive symptomatology in women. Intervention efforts might target women with young children by improving social support, educational or professional training opportunity, access to family counseling, and neighborhood environment.     

Peer communication skills and social behavioral characteristics of preschool children

The purpose of this study was to investigate the relationship between peer communication skills and social behavioral characteristics of preschool children. Data for 42 preschool children, five to nine years old, were analyzed in the study. Teachers were asked to rate the children on a number of social behavior measures, and classify them into competent, aggressive and withdrawn groups. It was shown that children of the withdrawn group accepted more requests from others than those of the other groups. Generally, in terms of feedback they gave, the withdrawn were not much different from the competent, but forms of feedback were more often nonverbal. As for the aggressive, feedback was more verbal than the withdrawn when another directly spoke to them, but tended to be equally nonverbal when it was not clear whom other were speaking to.     

Trait Affectivity and Nonreferred Adolescent Conduct Problems

This study examined for profiles of positive trait affectivity (PA) and negative trait affectivity (NA) associated with adolescent conduct problems. Prior trait affectivity research has been relatively biased toward the assessment of adults and internalizing symptomatology. Consistent with recent developmental modeling of antisocial behavior, this study proposed that conduct problems are uniquely associated with 2 PA-NA profiles (i.e., high PA-high NA and low PA-low NA). A nonreferred sample of 109 adolescents ages 12 to 19 was recruited to assess the independent relations between rating scale measures of the PA-NA dimensions and conduct problems, controlling for related internalizing (anxiety and depression) and externalizing (hyperactivity-impulsivity) symptomatology. The results generally confirmed the proposed interaction between the PA-NA dimensions in the prediction of adolescent conduct problems.
