Trajectories of pure and co-occurring internalizing and externalizing problems from age 2 to age 12: Findings from the National Institute of Child Health and Human Development Study of Early Child Care.

How and why do internalizing and externalizing problems, psychopathological problems from different diagnostic classes representing separate forms of psychopathology, co-occur in children? We investigated the development of pure and co-occurring internalizing and externalizing problems from ages 2 to 12 with the use of latent class growth analysis. Furthermore, we examined how early childhood factors (temperament, cognitive functioning, maternal depression, and home environment) and early adolescent social and behavioral adjustment variables were related to differential trajectories of pure and co-occurring internalizing and externalizing problems. The sample (National Institute of Child Health and Human Development Study of Early Child Care) consisted of 1,232 children (52% male). Mother reports on the Child Behavior Checklist (Achenbach, 1991, 1992) were used to construct the trajectories of externalizing and internalizing problems. Analyses identified groups of children exhibiting pure and co-occurring internalizing and externalizing problems. Children exhibiting continuous externalizing or continuous co-occurring internalizing and externalizing problems across the 10-year period under investigation were more likely to (a) engage in risky behaviors, (b) be associated with deviant peers, (c) be rejected by peers, and (d) be asocial with peers at early adolescence. However, children exhibiting pure internalizing problems over time were only at higher risk for being asocial with peers as early adolescents. Moreover, the additive effects of individual and environmental early childhood risk factors influenced the development of chronic externalizing problems, although pure internalizing problems were uniquely influenced by maternal depression. Results also provided evidence for the concepts of equifinality and multifinality. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Young children's social information processing: Family antecedents and behavioral correlates.

Little research has examined whether social information processing (SIP) measures from early childhood predict externalizing problems beyond the shared association with familial risk markers. In the present study, family antecedents and first-grade externalizing behaviors were studied in relation to preschool and 1st-grade SIP using data from the U.S. National Institute for Child Health and Human Development Study of Early Child Care (N=1,364). A subgroup of low-risk children reported only benign attributions in preschool and had few externalizing problems in 1st grade according to both teacher and mother reports. After controlling for gender and cognitive functioning, the authors found that maternal education and authoritarian attitudes were key predictors of this "Pollyanna preschooler" status and of SIP in 1st grade. However, small effect sizes for SIP variables underscore the need for new approaches to measurement and for further research on moderators of the link between SIP and children's behavior.

Sex differences in the longitudinal relations among family risk factors and childhood externalizing symptoms.

Despite potential sex differences in base rates, predictors, and maintaining processes for children's externalizing behaviors, little prospective research has examined sex differences in the relations between concurrent, proximal family risk factors and children's externalizing behaviors. The current study examined the relations among maternal depressive symptoms, maternal parenting behaviors (i.e., negativity and low warmth), and child externalizing symptoms at 24 months and first grade in a community-based sample of 1,364 children enrolled in the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development. Structural equation modeling revealed that maternal depression and negative parental behaviors were associated with concurrent externalizing behaviors, though maternal depression may be differentially linked to boys' and girls' externalizing problems. The relation between depression and boys' externalizing symptoms was more pronounced at 24 months, and over time, the relation between maternal depression and boys' externalizing symptoms decreased in magnitude, whereas this relation increased among girls.

Infant-mother attachment classification: Risk and protection in relation to changing maternal caregiving quality.

The relations between early infant-mother attachment and children's social competence and behavior problems during the preschool and early school-age period were examined in more than 1,000 children under conditions of decreasing, stable, and increasing maternal parenting quality. Infants' Strange Situation attachment classifications predicted mothers' reports of children's social competence and teachers' reports of externalizing and internalizing behaviors from preschool age through 1st grade. These relations appeared to be mediated by parenting quality; main effects of attachment classification disappeared when effects of parenting quality were controlled. Interactions were also observed. For example, when parenting quality improved over time, teachers rated children with insecure infant-mother attachments lower on externalizing behaviors; when parenting quality decreased, teachers rated insecure children higher on externalizing behaviors. In contrast, children classified as securely attached in infancy did not appear to be affected by declining or improving parenting quality.

The Family Health Project: Psychosocial adjustment of children whose mothers are HIV infected.

The psychosocial adjustment of 87 inner-city African American children 6–11 years old whose mothers were HIV infected was compared with that of 149 children from a similar sociodemographic background whose mothers did not report being HIV infected. Children were not identified as being HIV infected. Mother reports, child reports, and standardized reading achievement scores were used to assess 4 domains of adjustment: externalizing problems, internalizing problems, cognitive competence, and prosocial competence. The results indicated that, on average, children from both groups had elevated levels of behavior problem scores and low reading achievement scores when compared with national averages. Relative to children whose mothers were not infected, those whose mothers were HIV infected were reported to have more difficulties in all domains of psychosocial adjustment. Potential family processes that may explain the findings are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Productive Activity and the Prevention of Behavior Problems.

This study used data from the National Institute of Child Health and Human Development Study of Early Child Care to examine relations between parenting, self-control, and externalizing behavior among 1st graders. Of special concern was the relation between opportunities for productive activity and behavior problems and whether the relation was mediated by self-control. Evidence in favor of the hypothesis was observed for both mother-reported and teacher-reported externalizing behavior even with substantial controls on the models examined. Self-control also mediated relations for maternal harshness and maternal sensitivity. Somewhat surprisingly, the direct effect of maternal sensitivity on mother-reported externalizing behaviors was positive. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The Child Behavior Profile: II. Boys aged 12–16 and girls aged 6–11 and 12–16.

Based on the overall rationale and methodology described previously by the 1st author (see record 1979-12316-001), the present article reports the construction of editions of the Child Behavior Profile for boys aged 12–26 and girls aged 6–21 and 12–26 yrs. Scored from the Child Behavior Checklist, the profile consists of social competence and behavior problem scales derived from factor analysis of the checklists filled out by parents of 450 children of each sex and age group referred for mental health services. Second-order factor analyses showed that the behavior problem scales for each sample could be divided into broad-band groupings called "internalizing" and "externalizing." Normalized T scores for the social competence scales, behavior problem scales, internalizing, and externalizing were derived from nonclinical samples. Comparison of clinical and nonclinical samples showed significant differences on all social competence and behavior problem scores. Test–retest (1 wk) correlations averaged .87, and interparent correlations averaged .67. Comparison with findings for boys aged 6–11 yrs are reported. Computerized and hand-scored versions of the profile can be used to display item and scale scores for individual children. (7 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Infant attachment strategies, infant mental lag, and maternal depressive symptoms: predictors of internalizing and externalizing problems at age 7

The predictive relations between assessments in infancy and parent- and teacher-reported behavior problems at age 7 were investigated within a low-income sample. Infancy assessments indexed family adversity, parent-infant interaction at home, infant attachment, infant anger-distress at home, gender, and cognitive functioning. Among children at age 7 identified by teachers as highly externalizing, 83% were both disorganized in their attachment behavior in infancy and below the national mean in mental development scores at 18 months, compared with 13% of nonexternalizing children. Avoidant attachment behavior in infancy was associated with later internalizing symptoms rather than with externalizing symptoms. The behavior problem data reported by mother suggested the possibility of attachment-related biases in maternal report data. The results indicate that child mental lag in the context of a disorganized attachment relationship constitutes 1 early step on the pathway to school-age externalizing behavior.     

Family instability and the problem behaviors of children from economically disadvantaged families

This longitudinal study examined the relation between family instability and the problem behaviors of children from economically disadvantaged families. Family instability was assessed when the children were ages 5 and 7 and included number of residence changes, changes of intimate caregiver relationships, and recent negative life events. The results showed direct concurrent relations between family instability and preschool children's externalizing behavior in the context of other family process variables, relations between subsequent family instability and 1st-grade children's internalizing behavior (i.e., with preschool behavior ratings controlled), and an effect for persistent instability across grade. Moderator effects were also found for child variables, including gender, temperamental adaptability, and prior externalizing scores.     

Child-care effect sizes for the NICHD Study of Early Child Care and Youth Development.

This report summarizes findings from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development as effect sizes for exclusive maternal care and--for children in child care--type, quality, and quantity of care. Children (n = 1,261) were recruited at birth and assessed at 15, 24, 36, and 54 months. Exclusive maternal care did not predict child outcomes, but multiple features of child-care experience were modestly to moderately predictive. Higher quality child care was related to advanced cognitive, language, and preacademic outcomes at every age and better socioemotional and peer outcomes at some ages. More child-care hours predicted more behavior problems and conflict, according to care providers. More center-care time was related to higher cognitive and language scores and more problem and fewer prosocial behaviors, according to care providers. Child-care effect sizes are discussed from 3 perspectives: (a) absolute effect sizes, reflecting established guidelines; (b) relative effect sizes, comparing child-care and parenting effects; and (c) possible individual and collective implications for the large numbers of children experiencing child care.

Attachement et problèmes de comportements intériorisés et extériori?s auto-rapportés à la période scolaire.

The association between attachment and self-reported externalizing and internalizing behavior problems was examined for a diverse SES French-Canadian sample of 108 children. Attachment classifications were assigned on the basis of reunion behavior with mother when the children were approximately 6 years old. Child problem behavior was assessed two and a half years later using the Dominic test. Results indicated that boys with disorganized attachment and children with ambivalent attachment reported a higher level of externalizing problems then did secure children. Moreover, disorganized children also reported a higher level of internalizing problems than secure children. Child assessments using the Dominic in conjunction with a measure of separation-reunion behavior at age 5 to 7 can play an important role in the identification of school-aged children at risk for aggressive or anxious-depressive adaptive problems.

Within-child associations between family income and externalizing and internalizing problems.

Within-child associations between family income and child externalizing and internalizing problems were examined using longitudinal data from the NICHD Study of Early Child Care and Youth Development (2004a, 2004b; N = 1,132). Variations in income effects were estimated as a function of whether families were poor, whether mothers were partnered, and the number of hours mothers and their partners were employed. On average, children had fewer externalizing problems during times when their families' incomes were relatively high than during times when their families' incomes were relatively low; the estimated benefits of increased income were greatest for children who were chronically poor. For both externalizing and internalizing problems, income was most strongly associated with problems when chronically poor children's mothers were partnered and employed.

Trajectories of internalizing, externalizing, and grades for children who have and have not experienced their parents' divorce or separation.

This study examined whether the occurrence and timing of parental separation or divorce was related to trajectories of academic grades and mother- and teacher-reported internalizing and externalizing problems. The authors used hierarchical linear models to estimate trajectories for children who did and did not experience their parents' divorce or separation in kindergarten through 10th grade (N = 194). A novel approach to analyzing the timing of divorce/separation was adopted, and trajectories were estimated from 1 year prior to the divorce/separation to 3 years after the event. Results suggest that early parental divorce/separation is more negatively related to trajectories of internalizing and externalizing problems than is later divorce/separation, whereas later divorce/separation is more negatively related to grades. One implication of these findings is that children may benefit most from interventions focused on preventing internalizing and externalizing problems, whereas adolescents may benefit most from interventions focused on promoting academic achievement.

Child Personality and Parental Behavior as Moderators of Problem Behavior: Variable- and Person-Centered Approaches.

Parenting × Child Personality interactions in predicting child externalizing and internalizing behavior were investigated in a variable-centered study and a person-centered study. The variable-centered study used data from a 3-year longitudinal study of 600 children 7 to 15 years old at Time 1 and 512 children 10 to 18 years old at Time 2. Parents rated child personality (five factor model), negative control, positive parenting, and child problem behavior, whereas children rated parental behavior. Hierarchical moderated regression analyses showed significant Parenting × Child Personality (benevolence and conscientiousness) interactions, principally for externalizing behavior. The interactions were largely replicable across informants and across time. The person-centered study, which classified participants into 3 types, showed that negative parental control was more related to externalizing behavior for undercontrollers than for resilients. Negative parental control enhanced internalizing behavior for overcontrollers. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Parental corporal punishment predicts behavior problems in early childhood.

Using data from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development (Research Triangle Institute, 2002), this study examined the impact of corporal punishment (CP) on children's behavior problems. Longitudinal analyses were specified that controlled for covarying contextual and parenting variables and that partialed child effects. The results indicate that parental CP uniquely contributes to negative behavioral adjustment in children at both 36 months and at 1st grade, with the effects at the earlier age more pronounced in children with difficult temperaments. Parents and mental health professionals who work to modify children's negative behavior should be aware of the unique impact that CP likely plays in triggering and maintaining children's behavior problems. Broad-based family policies that reduce the use of this parenting behavior would potentially increase children's mental health and decrease the incidence of children's behavior problems.

Infant–mother attachment and children's friendship quality: Maternal mental-state talk as an intervening mechanism.

Utilizing data from the Eunice Kennedy Shriver National Institute of Child Health and Human Development's Study of Early Child Care and Youth Development, we investigated mothers' talk about mental states during play with their 24-month-old children as a mechanism though which infant–mother attachment was associated with children's later friendship quality. A series of repeated measures analyses of covariance indicated that a secure versus avoidant or disorganized infant–mother attachment was associated with more maternal talk about cognitions (but not emotions or desires) at 24 months. Latent growth curve models tested within a structural equation modeling framework revealed indirect effects of infant–mother attachment on observed and mother-reported positive friendship interaction at 54 months and decreases in mother-reported negative friendship interaction from 54 months to 1st grade via maternal cognitive talk at 24 months.

The power of friendship: Protection against an escalating cycle of peer victimization.

This study examined 2 aspects of friendship (presence and perceived qualities of a best friend) as moderators of behavioral antecedents and outcomes of peer victimization. A total of 393 children (188 boys and 205 girls) in the 4th and 5th grades (mean age 10 years 7 months) participated during each of 2 waves of data collection in this 1-year longitudinal study. Results indicated that teacher-reported internalizing and externalizing behaviors predicted increases in peer-reported victimization, but the relation of internalizing behaviors to increases in victimization was attenuated for children with a protective friendship. Victimization predicted increases in internalizing and externalizing behaviors but only for children without a mutual best friendship. Results highlight the importance of peer friendships in preventing an escalating cycle of peer abuse. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Neighborhood disadvantage as a moderator of the association between harsh parenting and toddler-aged children's internalizing and externalizing problems.

Neighborhood dangerousness and belongingness were expected to moderate associations between harsh parenting and toddler-age children's problem behaviors. Fifty-five predominantly African American mothers participated with their 2-year old children. Neighborhood danger, neighborhood belongingness, and children's problem behaviors were measured with mothers' reports. Harsh parenting was measured with observer ratings. Analyses considered variance common to externalizing and internalizing problems, using a total problems score, and unique variance, by controlling for internalizing behavior when predicting externalizing behavior, and vice versa. Regarding the common variance, only the main effects of neighborhood danger and harsh parenting were significantly associated with total problem behavior. In contrast, after controlling for externalizing problems, the positive association between harsh parenting and unique variance in internalizing problems became stronger as neighborhood danger increased. No statistically significant associations emerged for the models predicting the unique variance in externalizing problems or models considering neighborhood belongingness.

Maternal stress and emotional status during the perinatal period and childhood adjustment.

An emerging literature suggests that maternal distress during the prenatal and perinatal period may adversely affect offspring development. The association between maternal stress and emotional status in the perinatal period (defined as 1 month after birth) and adjustment of first-grade children was examined in 948 mother-child dyads from the NICHD Study of Early Child Care using hierarchical multiple regression. Maternal demographic characteristics, including maternal education and income, accounted for 4% of the variance in Child Behavior Checklist (CBCL) externalizing scores when children were in first grade. Maternal stress and emotional status at 1 month accounted for an additional 4% of the variance in CBCL externalizing t scores; statistically significant contributions were made by maternal depression and perceived social support. Maternal depression and parenting stress at 1 month made statistically significant contributions to CBCL internalizing scores at first grade. These findings contribute to a growing body of literature indicating that perinatal maternal adjustment is associated with children's emotional and behavioral functioning years later. Implications for school psychologists' involvement in prevention, assessment, and intervention practices are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Pretrauma problems, prior stressor exposure, and gender as predictors of change in posttraumatic stress symptoms among physically injured children and adolescents.

Objective: This study addressed predictors of change in posttraumatic stress symptoms (PTSS) among youths who had experienced physical injuries. The influences of pretrauma internalizing and externalizing problems, prior stressor exposure, and gender were investigated. Additionally, gender was examined as a moderator of the associations between internalizing problems and PTSS, externalizing problems and PTSS, and prior stressor exposure and PTSS. Method: Participants were 157 children and adolescents (75% male; age M = 13.30 years, SD = 3.60; 44% Caucasian, 39% African American, 13% Hispanic, and 4% other) admitted to 2 hospitals for physical injuries. Youths and their parents completed measures of PTSS (Child Posttraumatic Stress Reaction Index), internalizing and externalizing problems (Child Behavior Checklist), and prior stressor exposure (Coddington Life Events Scale, Child) during the hospital stay; youths completed up to 3 additional PTSS assessments targeted at 3, 6, and 12 months postinjury. Results: Multilevel regression analyses revealed a significant average decline in PTSS over time (p p p
