Narrative representations of caregivers and self in maltreated pre-schoolers

This study examined narrative representations of parents and of self, as well as child behavior during the assessment, in maltreated (N = 56) and demographically comparable non-maltreated (N = 37) pre-school-aged children in a one-year longitudinal study. Maltreated children evidenced more negative representations of parents and of self at Time 2, including the juxtaposition of both a negative and a grandiose self. Over time there was a marginal interaction such that maltreated children portrayed fewer disciplining parent representations and nonmaltreated children portrayed more. Also over time, maltreated children portrayed marginally more grandiose self-representations and nonmaltreated children fewer. Furthermore, maltreated children demonstrated less responsivity to the examiner over time and nonmaltreated children demonstrated more. The deleterious effects of maltreatment on representations of self and of others, especially as development proceeds, are discussed, and the importance of providing attachment-informed intervention prior to the consolidation of these negative representations is highlighted.     

Dimensions of child maltreatment and children's adjustment: contributions of developmental timing and subtype.

This investigation examined the dimensions of developmental timing, subtype, and severity of maltreatment and their relations with child adaptation. The 814 children who participated in a summer day camp, 492 of whom were maltreated and 322 of whom were nonmaltreated comparison children, were assessed by camp counselors on their internalizing and externalizing symptomatology, aggressive, withdrawn, and cooperative behavior, and on personality dimensions of ego resiliency and ego control, and were rated by peers on disruptive, aggressive, and cooperative behavior. The severity within each subtype of maltreatment and the developmental period in which each subtype occurred were examined through hierarchical regression analyses. Additionally, children with similar timing or subtype patterns were grouped to explore diversity in outcomes. Results highlighted the role of severity of emotional maltreatment in the infancy-toddlerhood period and physical abuse during the preschool period in predicting externalizing behavior and aggression. Severity of physical neglect, particularly when it occurred during the preschool period, was associated with internalizing symptomatology and withdrawn behavior. Additionally, maltreatment during the school-age period contributed significant variance after earlier maltreatment was controlled. Chronic maltreatment, especially with onset during infancy-toddlerhood or preschool periods, was linked with more maladaptive outcomes. The implications of measuring multiple dimensions for improving research in child maltreatment are discussed.     

Maternal Childhood Maltreatment History and Child Mental Health: Mechanisms in Intergenerational Effects

The objectives of this study were to examine whether a maternal history of maltreatment in childhood has a detrimental impact on young children’s mental health and to test theoretically and empirically informed pathways by which maternal history may influence child mental health. Mother–child dyads (N = 187) were evaluated between birth and 64 months of age via home and laboratory observations, medical and child protection record reviews, and maternal interviews to assess maternal history of childhood maltreatment and microsystem and exosystem measures of the caregiving context, including child maltreatment, maternal caregiving quality, stress exposures, and social support. When the children were 7 years of age, mothers and teachers reported on child emotional and behavioral problems. Analyses examined whether the caregiving context variables linked maternal maltreatment history with child emotional and behavioral problems, controlling for child sex (54% male), race/ethnicity (63% White), and family sociodemographic risk at birth. Maltreated mothers experienced greater stress and diminished social support, and their children were more likely to be maltreated across early childhood. By age 7, children of maltreated mothers were at increased risk for clinically significant emotional and behavioral problems. A path analysis model showed mediation of the effects of maternal childhood maltreatment history on child symptoms, with specific effects significant for child maltreatment. Interventions that reduce child maltreatment risk and stress exposures and increase family social support may prevent deleterious effects of maternal childhood maltreatment history on child mental health.     

The ecology of adolescent maltreatment: a multilevel examination of adolescent physical abuse, sexual abuse, and neglect

This study examined the individual characteristics, family relations, and stress/social support of 50 maltreated adolescents and their mothers. Dyads were divided into 4 demographically similar groups: neglect, physical abuse, sexual abuse, and nonmaltreatment control. Results show that adolescent neglect was primarily associated with extrafamilial difficulties and social isolation. Adolescent physical abuse was linked more with rigidity in family relations, poorer maternal understanding of child developmental skills, and adolescent externalizing behaviors. In contrast, adolescent sexual abuse was related to maternal emotional problems and adolescent internalizing behaviors. In general, each group of maltreated adolescents experienced lower levels of family cohesion, more attention problems, and more daily stress than did their nonmaltreated counterparts. Findings are consistent with an ecological model of adolescent maltreatment.     

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.     

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.     

The relative efficacy of two interventions in altering maltreated preschool children's representational models: implications for attachment theory

A narrative story-stem task was used to evaluate the efficacy of two competing, developmentally informed preventive interventions for maltreated preschoolers and their mothers designed to modify children's internal representations of self and of self in relation to other. One hundred and twenty-two mothers and their preschoolers (87 maltreated and 35 nonmaltreated) served as participants. Maltreating families were randomly assigned to either the preschooler-parent psychotherapy (PPP, n = 23), psychoeducational home visitation (PHV, n = 34), or community standard (CS, n = 30) intervention group at baseline. Thirty-five nonmaltreating (NC) families served as comparisons. Narratives were administered to children at baseline and at the postintervention evaluation. Children in the PPP intervention evidenced more of a decline in maladaptive maternal representations over time than PHV and CS children and displayed a greater decrease in negative self-representations than CS, PHV, and NC children. Also, the mother-child relationship expectations of PPP children became more positive over the course of the intervention, as compared to NC and PHV participants. These results suggest that an attachment-theory informed model of intervention (PPP) is more effective at improving representations of self and of caregivers than is a didactic model of intervention directed at parenting skills. Findings are discussed with respect to their implications for developmental theory, with a specific focus on attachment theory and internal working models of relationships.     

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.     

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.     

Factors influencing maltreated children's early adjustment in foster care

Internal representations of self and primary attachment figures may be one mechanism by which maltreatment affects children's interpersonal behavior and relationships with others. Research on the continuity and influence of maltreated children's attachment representations, however, has not included youngsters removed from abusive or neglectful home environments. This paper examines the influence of maltreated children's maternal and self-representations on subsequent relationships with foster mothers and behavioral adjustment in foster care. Participants included 32 children, ages 9-13 years, who entered foster placement for the first time after a sustained relationship with a maltreating biological mother. Upon initially entering foster care, children's maternal and self-representations were significantly related to each other and to severity of maltreatment history but not to other factors believed to influence the quality of parent-child relationship (e.g., maternal mental health, partner stability). In addition, these representations significantly predicted children's subsequent views of their relationships with foster mothers. Finally, children's behavior in their foster homes was associated with maltreatment severity, internal representations assessed at entry into foster care, and to concurrent perceptions of their new foster mothers. These findings advance our understanding of foster placement's role in maltreated children's development and provide preliminary insight into the processes associated with the formation of potentially compensatory relationships.     

Adrenocortical responses to strangers in preschoolers: relations with parenting, temperament, and psychopathology

Previous research has provided inconsistent evidence for the relations between young children's hypothalamic-pituitary-adrenal (HPA) functioning and their temperament, parenting, and adjustment. Building biopsychosocial models of adjustment, we examined how temperamental inhibition and maternal punishment contributed to preschoolers' adrenocortical activity while interacting with adult strangers. We also examined whether HPA functioning moderated relations between dispositional and familial factors and children's internalizing and externalizing problems. A total of 402 preschool-aged children from three independent samples with parallel and overlapping measures were studied. Salivary cortisol levels were measured twice while interacting with adult strangers during testing protocols. Mothers reported on temperamental inhibition, maternal punishment and children's problems. Maternal punishment predicted higher cortisol levels 20 and 65 min after meeting adult strangers. Prolonged cortisol elevation was associated with having fewer externalizing problems. Boys who experienced more maternal punishment and had higher cortisol 20 min after meeting strangers manifested more externalizing problems. Girls who were more inhibited and had prolonged cortisol elevations had more internalizing problems. In accord with biopsychosocial models of psychopathology, HPA functioning in preschoolers was sensitive to variations in socialization experiences, and moderated children's risk for emotional and behavioral problems.     

Pathways from child maltreatment to internalizing problems: perceptions of control as mediators and moderators.

Using a prospective longitudinal design, we examined internalizing problems and perceptions of control in a community sample of 785 children, 59 of whom had been maltreated. Children's internalizing problems and perceptions of control were measured via self-report at annual assessments in third grade through seventh grade (modal ages 9-13 years). Children's experiences of multiple types of maltreatment were rated based on social service records, using a standard coding system. Results of longitudinal analyses examining the roles of specific types of maltreatment (neglect, harsh parenting, and sexual abuse) revealed that neglect and sexual abuse were each associated with more internalizing problems, especially among children who experienced both these maltreatment types. Neglected children reported higher levels of perceived external control than other children did. Sexual abuse was associated with higher levels of perceived external control, but only among children who had also been neglected. Results of mediation analyses showed that higher levels of perceived external control accounted substantially for associations between specific maltreatment types and children's internalizing problems. Results of moderator analyses revealed that, among maltreated children, greater perceived internal control predicted fewer internalizing problems, suggesting that perceived internal control functioned as a protective factor. Children maltreated early in life were less likely to have this protective characteristic. Results are discussed in terms of their implications for understanding the developmental consequences of specific and co-occurring types of maltreatment.     

Nature X nurture: genetic vulnerabilities interact with physical maltreatment to promote conduct problems

Maltreatment places children at risk for psychiatric morbidity, especially conduct problems. However, not all maltreated children develop conduct problems. We tested whether the effect of physical maltreatment on risk for conduct problems was strongest among those who were at high genetic risk for these problems using data from the E-risk Study, a representative cohort of 1,116 5-year-old British twin pairs and their families. Children's conduct problems were ascertained via parent and teacher interviews. Physical maltreatment was ascertained via parent report. Children's genetic risk for conduct problems was estimated as a function of their co-twin's conduct disorder status and the pair's zygosity. The effect of maltreatment on risk for conduct problems was strongest among those at high genetic risk. The experience of maltreatment was associated with an increase of 2% in the probability of a conduct disorder diagnosis among children at low genetic risk for conduct disorder but an increase of 24% among children at high genetic risk. Prediction of behavioral pathology can attain greater accuracy if both pathogenic environments and genetic risk are ascertained. Certain genotypes may promote resistance to trauma. Physically maltreated children whose first-degree relatives engage in antisocial behavior warrant priority for therapeutic intervention.     

Preschoolers’ narrative representations and childhood adaptation in an ethnoracially diverse sample

This investigation evaluated relations between preschoolers’ representational content and coherence in the MacArthur Story Stem Battery (MSSB) at age four as related to child adjustment at age six. A community sample of 250 preschoolers (50% female; M_age= 49.05 months, SD = 2.9; 46% Hispanic, 18% Black, 11.2% White, 0.4% Asian, and 24.4% multiracial) completed assessments of relational representations using the MSSB at age four and of child adjustment at age six, including a measure of child-reported depressive symptomatology and observer ratings of child aggression during a Bobo doll task and inhibitory control during a delay of gratification task. Regression analyses demonstrated prospective relations between negative mother representation and less inhibitory control, negative child representation and higher aggression, and narrative coherence and more inhibitory control. Interactive analyses revealed relations between negative mother representation and difficulties in inhibitory control among White children and weaker relations among Black children. Prospective relations between narrative coherence and increased inhibitory control were less pronounced for Hispanic children. Findings indicate that preschoolers’ narratives can reveal the thematic content and structural coherence of their internalized beliefs and expectations of self and (m)other. Associations between representations and children’s adaptation have clear implications for representational processes and interventions in development.     

A Longitudinal Study of Fathers’ and Young Children’s Depressive Symptoms

Considerable research has examined the effects of maternal depression on children, but few studies have focused on the relation between paternal and child depressive symptoms, particularly during early childhood. Even fewer studies have been longitudinal, leaving open questions about how paternal and child depression covary over time. The present study sought to address this gap by examining the relation between fathers’ and children’s depressive symptoms over a 3-year period. Participants were 153 preschool children with behavior problems and their parents. Three longitudinal analytic approaches were used to examine how father and child depression change together and predict one another over time. Additional analyses examined whether externalizing problems or maternal depression might account for the associations between fathers’ and children’s depressive symptoms. Changes in paternal depression significantly predicted changes in father-reported and mother-reported child depressive symptoms. These effects were evident both in year-to-year fluctuations and in linear trajectories across the 3-year period. Cross-lagged analyses suggested that these relations may have been driven by father-effects; paternal depression at one time point predicted child depression at the next time point, but child depression did not significantly predict later paternal depression. We found little evidence that externalizing problems or maternal depression accounted for the relations between fathers’ and children’s depressive symptoms. Results provide convergent evidence that fathers’ depression may play an important role in the development of depressive symptoms in young children and underscore the importance of including fathers in studies of depression in families.     

Marital Adjustment,Marital Discord Over Childrearing,and Child Behavior Problems: Moderating Effects of Child Age

Examined whether marital discord over childrearing contributes to child behavior problems after taking into account general marital adjustment, and if child age moderates associations between child behavior problems and either general marital adjustment or marital discord over childrearing. Participants were 146 two-parent families seeking services for their child's (4 to 9 years of age) conduct problems. Data on marital functioning and child behavior problems were collected from both parents. Mothers' and fathers' reports of marital discord over childrearing related positively to child externalizing problems after accounting for general marital adjustment. Child age moderated associations between fathers' reports of general marital adjustment and both internalizing and externalizing child problems, with associations being stronger in families with younger children. The discussion highlights the role that developmental factors may play in understanding the link between marital and child behavior problems in clinic-referred families.     

The efficacy of time-limited play therapy with maltreated preschoolers

Despite recognition of child maltreatment as a major national problem, there have been no controlled studies that evaluated the efficacy of individual psychotherapy with maltreated children. Thirty-six preschoolers who were attending a therapeutic nursery were provided with either 15 weeks of directive individual play therapy to supplement their ongoing milieu therapy or with their milieu therapy only. Of 13 outcome measures, children in the treatment group were superior to control children at posttest on amount of isolated play, and there were no significant differences at a 10-week followup assessment. Possible explanations for the general lack of significant results were discussed.     

Maltreatment of boys and the development of disruptive and delinquent behavior.

Data from a longitudinal, inner-city community sample were used to examine the prevalence of child maltreatment in males and to relate this to disruptive and delinquent child behavior. By age 18 years, almost one fourth of the families had been referred to Children and Youth Services (CYS). Investigation by the CYS resulted in substantiated maltreatment of 10% of the participants, mostly for physical abuse and neglect. Almost all maltreatment was perpetrated by people living in the same house as the victim. Maltreatment was related to the boys progressing on three pathways in disruptive and delinquent behavior: authority conflict pathway, overt pathway, and covert pathway. Two thirds of the victims showed authority conflict problems, and almost all of the maltreated boys displayed behaviors characteristic of the overt and covert pathways. Victims, compared to matched controls, were more likely to have engaged in behaviors characteristic of the authority conflict and the overt pathways but less strongly engaged in behaviors associated with the covert pathway. Victims were also more likely than controls to have a referral to juvenile court. Most of the CYS contact tended to precede or co-occur with onset of overt and covert problem behavior, but about half of the onset of authority conflict behaviors tended to precede contact with CYS.     

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.

Gene × Environment interaction and resilience: effects of child maltreatment and serotonin, corticotropin releasing hormone, dopamine, and oxytocin genes

In this investigation, gene-environment interaction effects in predicting resilience in adaptive functioning among maltreated and nonmaltreated low-income children (N = 595) were examined. A multicomponent index of resilient functioning was derived and levels of resilient functioning were identified. Variants in four genes (serotonin transporter linked polymorphic region, corticotropin releasing hormone receptor 1, dopamine receptor D4-521C/T, and oxytocin receptor) were investigated. In a series of analyses of covariance, child maltreatment demonstrated a strong negative main effect on children's resilient functioning, whereas no main effects for any of the genotypes of the respective genes were found. However, gene-environment interactions involving genotypes of each of the respective genes and maltreatment status were obtained. For each respective gene, among children with a specific genotype, the relative advantage in resilient functioning of nonmaltreated compared to maltreated children was stronger than was the case for nonmaltreated and maltreated children with other genotypes of the respective gene. Across the four genes, a composite of the genotypes that more strongly differentiated resilient functioning between nonmaltreated and maltreated children provided further evidence of genetic variations influencing resilient functioning in nonmaltreated children, whereas genetic variation had a negligible effect on promoting resilience among maltreated children. Additional effects were observed for children based on the number of subtypes of maltreatment children experienced, as well as for abuse and neglect subgroups. Finally, maltreated and nonmaltreated children with high levels of resilience differed in their average number of differentiating genotypes. These results suggest that differential resilient outcomes are based on the interaction between genes and developmental experiences.
