Behavioral Control Dynamics and Developmental Outcomes in Infants Prenatally Exposed to Cocaine

This study longitudinally examined the associations between mother–infant interactions at 15 months and behavioral and cognitive outcomes at 36 months of age in a sample of at‐risk, young children. Participants for the current study were 58 infants/toddlers prenatally exposed to cocaine and their maternal caregivers. These infants were from a low socioeconomic status background and were part of an intervention setting. When the children were 12, 15, and 36 months, they participated in research sessions with their maternal caregivers. Cognitive development at 12 months and maternal and infant behavior at 15 months were measured to predict behavioral and cognitive outcome at 36 months. Higher levels of maternal control at 15 months were marginally significant in predicting higher levels of problem behavior at 36 months whereas higher levels of infant resistance to control predicted lower levels of problem behavior. Furthermore, control‐resistant behavior displayed by infants was a unique buffer against problem behavior, even after controlling for maternal factors and cognitive abilities. These findings suggest that maternal control attempts and infant reactions to those maternal control behaviors play an important role in the development of adaptive and maladaptive behavior patterns during early childhood.     

Behavior Problems in Middle Childhood: The Predictive Role of Maternal Distress, Child Attachment, and Mother-Child Interactions

The objective of the study was to examine the longitudinal relation between early school-age measures of maternal psychosocial distress, quality of mother-child interactions, and child attachment behavior, and behavior problem profiles in middle childhood using a multi-informant design. Participants were 243 French-speaking mother-child dyads (122 girls) who were part of an ongoing longitudinal project. Maternal psychosocial distress was assessed when children were between 4 and 6 years of age. Mother-child interactive quality and attachment patterns were observed at age 6 during a laboratory visit. At age 8.5, externalizing and internalizing problems were assessed using mother and child reports. Results show that maternal psychosocial distress predicted later social adaptation reported by the child through the mediation of mother-child interactions. Analyses also revealed that higher maternal psychosocial distress and controlling attachment patterns, either of the punitive or caregiving type, significantly predicted membership in both child internalizing and externalizing clinical problem groups. Lower mother-child interactive quality, male gender, and child ambivalent attachment were also predictors of externalizing clinical problems.     

Multiple Determinants of Externalizing Behavior in 5-Year-Olds: A Longitudinal Model

In a community sample of 116 children, assessments of parent-child interaction, parent-child attachment, and various parental, child, and contextual characteristics at 15 and 28 months and at age 5 were used to predict externalizing behavior at age 5, as rated by parents and teachers. Hierarchical multiple regression analysis and path analysis yielded a significant longitudinal model for the prediction of age 5 externalizing behavior, with independent contributions from the following predictors: child sex, partner support reported by the caregiver, disorganized infant-parent attachment at 15 months, child anger proneness at 28 months, and one of the two parent-child interaction factors observed at 28 months, namely negative parent-child interactions. The other, i.e., a lack of effective guidance, predicted externalizing problems only in highly anger-prone children. Furthermore, mediated pathways of influence were found for the parent-child interaction at 15 months (via disorganized attachment) and parental ego-resiliency (via negative parent-child interaction at 28 months).

Unresolved states of mind, disorganized attachment relationships, and disrupted interactions of adolescent mothers and their infants

The links between unresolved maternal attachment status, disrupted maternal interaction in play situations, and disorganized attachment relationships were examined in a study of 82 adolescent mother-infant dyads. Maternal interactive behavior was measured using the Atypical Maternal Behavior Instrument for Assessment and Classification coding system. Additional rating scales were developed to correspond to the 5 dimensions of disrupted maternal behavior outlined by E. Bronfman, E. Parsons, and K. Lyons-Ruth (1999). A robust association was observed between disrupted maternal behavior and disorganized attachment. Ratings of disrupted maternal behavior revealed that disorganized attachment relationships were strongly related to ratings of fearful/disoriented behavior. Moreover, mothers who were unresolved were more likely than not-unresolved mothers to show disrupted patterns of interaction with their infants. Regression analyses suggested that disrupted behavior statistically mediated the association between unresolved status and disorganized attachment relationships.     

Exploration of the links among fathers' unresolved states of mind with respect to attachment,atypical paternal behavior,and disorganized infant–father attachment

Atypical maternal behavior has consistently been identified as a precursor of disorganized infant–mother attachment, but to date, no research has examined the role of atypical paternal behavior in the development of disorganized infant–father attachment. This study aims to enhance our understanding and conceptualization of infant–father attachment by examining the role of fathers' unresolved states of mind and the display of atypical paternal behavior in the development of disorganized infant–father attachment. Thirty‐one middle‐class couples participated in this study. Maternal and paternal Adult Attachment Interviews (C. George, N. Kaplan, & M. Main, 1996 ) were completed prenatally and at infant age 6 months, respectively. Infant–mother and infant–father dyads participated in the Strange Situation paradigm (M. Ainsworth, M. Blehar, E. Waters, & S. Wall, 1978 ) when the infants were 12 and 18 months of age, respectively. The Atypical Maternal Behavior Instrument for Assessment and Classification (E. Bronfman, E. Parsons, & K. Lyons‐Ruth, 1999 ) was used to assess maternal and paternal behavior during the Strange Situation. Maternal states of mind regarding attachment predicted infant–mother attachment relationships, and paternal states of mind predicted infant–father attachment relationships. Atypical maternal behavior was associated with infant–mother disorganized attachment; however, atypical paternal behavior did not predict infant–father disorganized attachment. Thus, it is possible that other factors, yet to be uncovered, might contribute to the development of infant–father disorganized attachment.     

Interactions Between Maternal Parenting and Children’s Early Disruptive Behavior: Bidirectional Associations across the Transition from Preschool to School Entry

This study was a prospective 2-year longitudinal investigation of associations between negative maternal parenting and disruptive child behavior across the preschool to school transition. Our main goals were to 1) determine the direction of association between early maternal negativity and child disruptive behaviors across this important developmental transition and 2) examine whether there would be different patterns of associations for boys and girls. Participants were 235 children (111 girls; T1; M = 37.7 months, T2; M = 63.4 months) and their mothers and teachers. Observational and multi-informant ratings of child disruptive behavior showed differential patterns of stability and associations with measures of parenting risk. Results indicated bidirectional and interactive contributions of externalizing behavior and negative parenting across time. Results also indicated that risk mechanisms operate similarly for both sexes. Findings support transactional models of disruptive child behavior that highlight the joint contributions of parents and children.     

Longitudinal stability of temperamental exuberance and social-emotional outcomes in early childhood

The goals of the current study were to investigate the stability of temperamental exuberance across infancy and toddlerhood and to examine the associations between exuberance and social-emotional outcomes in early childhood. The sample consisted of 291 4-month-olds followed at 9, 24, and 36 months and again at 5 years of age. Behavioral measures of exuberance were collected at 9, 24, and 36 months. At 36 months, frontal electroencephalogram (EEG) asymmetry was assessed. At 5 years, maternal reports of temperament and behavior problems were collected, as were observational measures of social behavior during an interaction with an unfamiliar peer in the laboratory. Latent profile analysis revealed a high, stable exuberance profile that was associated with greater ratings of 5-year externalizing behavior and surgency, as well as observed disruptive behavior and social competence with unfamiliar peers. These associations were particularly true for children who displayed left frontal EEG asymmetry. Multiple factors supported an approach bias for exuberant temperament but did not differentiate between adaptive and maladaptive social-emotional outcomes at 5 years of age.     

Quality of attachment,perinatal risk,and mother–infant interaction in a high‐risk premature sample

Thirty‐three families, each with a premature infant born less than 33 gestational weeks, were observed in a longitudinal exploratory study. Infants were recruited in a neonatal intensive care unit, and follow‐up visits took place at 4 months and 12 months of corrected age. The severity of the perinatal problems was evaluated using the Perinatal Risk Inventory (PERI; A.P. Scheiner & M.E. Sexton, 1991 ). At 4 months, mother–infant play interaction was observed and coded according to the CARE‐index (P.M. Crittenden, 2003 ); at 12 months, the Strange Situation Procedure (SSP; M.D.S. Ainsworth, M.C. Blehar, E. Waters, & S. Wall, 1978 ) was administered. Results indicate a strong correlation between the severity of perinatal problems and the quality of attachment at 12 months. Based on the PERI, infants with high medical risks more frequently tended to be insecurely attached. There also was a significant correlation between insecure attachment and dyadic play interaction at 4 months (i.e., maternal controlling behavior and infant compulsive compliance). Moreover, specific dyadic interactive patterns could be identified as protective or as risk factors regarding the quality of attachment. Considering that attachment may have long‐term influence on child development, these results underline the need for particular attention to risk factors regarding attachment among premature infants.     

Mother–Infant Joint Attention and Sharing: Relations to Disorganized Attachment and Maternal Disrupted Communication

The normative development of infant shared attention has been studied extensively, but few studies have examined the impact of disorganized attachment and disturbed maternal caregiving on mother–infant shared attention. The authors examined both maternal initiations of joint attention and infants’ responses to those initiations during the reunion episodes of the Strange Situation Procedure at 12 and 18 months of infant age. The mothers' initiations of joint attention and three forms of infant response, including shunning, simple joint attention, and sharing attention, were examined in relation to infant disorganized attachment and maternal disrupted communication. Mothers who were disrupted in communication with their infants at 18 months initiated fewer bids for joint attention at 12 months, and, at 18 months, mothers of infants classified disorganized initiated fewer bids. However, the infant' responses were unrelated to either the infant' or the mother' disturbed attachment. At both ages, disorganized infants and infants of disrupted mothers were as likely to respond to maternal bids as were their lower risk counterparts. Our results suggest that a disposition to share experiences with others is robust in infancy, even among infants with adverse attachment experiences, but this infant disposition may depend on adult initiation of bids to be realized.     

Behavioural precursors of attachment representations in middle childhood and links with child social adaptation

Concordance between age‐6 attachment behaviour and age‐8 doll play attachment representations during the school‐age period, and associations between these measures and child social adaptation at school were examined. One hundred and twenty‐nine 6‐year‐olds and their mothers participated in a separation/reunion protocol. Two years later, 104 children completed a doll play narrative task. Teachers evaluated child behaviour problems and prosocial behaviour at both ages. Results showed a significant four‐way concordance between age‐6 attachment behaviour and age‐8 doll play classifications. Each of the four attachment classifications was concordant in the absence of major negative life‐events, but only the disorganized classifications remained concordant when at least one negative life‐event occurred between the two assessment times. Children with a disorganized attachment classification or representation had higher externalizing scores than secure and avoidant children at both timepoints. Finally, the avoidant and disorganized behavioural classifications predicted avoidant and disorganized representations, respectively, even when controlling for age‐6 teacher reports of social adaptation.     

Correlates of attachment at age 3: construct validity of the preschool attachment classification system

This study examined correlates of attachment at age 3 to further validate preschool separation-reunion measures. Three-year-olds (N = 150) and their mothers participated in a separation-reunion protocol, the Preschool Attachment Classification System (PACS: J. Cassidy & R. S. Marvin with the MacArthur Working Group on Attachment, 1992), and a mother-child interaction session during a laboratory visit. Mothers also completed psychosocial measures and, along with teachers, evaluated child behavior problems. The secure and disorganized groups received, respectively, the highest and lowest interaction scores. Disorganized children showed a higher level of teacher-reported externalizing and internalizing problems than did secure children. Mothers of insecure children reported higher child externalizing (all insecure groups) and internalizing (avoidant group) scores, more personal distress related to emotional bonding (disorganized group), childrearing control (ambivalent group), and child hyperactivity (avoidant group). Results strongly support the validity of the PACS as a measure of attachment in 3-year-olds.     

Impact of Behavioral Inhibition and Parenting Style on Internalizing and Externalizing Problems from Early Childhood through Adolescence

Behavioral inhibition (BI) is characterized by a pattern of extreme social reticence, risk for internalizing behavior problems, and possible protection against externalizing behavior problems. Parenting style may also contribute to these associations between BI and behavior problems (BP). A sample of 113 children was assessed for BI in the laboratory at 14 and 24 months of age, self-report of maternal parenting style at 7 years of age, and maternal report of child internalizing and externalizing BP at 4, 7, and 15 years. Internalizing problems at age 4 were greatest among behaviorally inhibited children who also were exposed to permissive parenting. Furthermore, greater authoritative parenting was associated with less of an increase in internalizing behavior problems over time and greater authoritarian parenting was associated with a steeper decline in externalizing problems. Results highlight the importance of considering child and environmental factors in longitudinal patterns of BP across childhood and adolescence.     

Chronicity, severity, and timing of maternal depressive symptoms: relationships with child outcomes at age 5

The relationships between severity, chronicity, and timing of maternal depressive symptoms and child outcomes were examined in a cohort of 4,953 children. Mothers provided self-reports of depressive symptoms during pregnancy, immediately postpartum, and when the child was 6 months old and 5 years old. At the age 5 follow-up, mothers reported on children's behavior and children completed a receptive vocabulary test. Results suggest that both the severity and the chronicity of maternal depressive symptoms are related to more behavior problems and lower vocabulary scores in children. The interaction of severity and chronicity of maternal depressive symptoms was significantly related to higher levels of child behavior problems. Timing of maternal symptoms was not significantly related to child vocabulary scores, but more recent reports of maternal depressive symptoms were associated with higher rates of child behavior problems.     

Mother-child patterns of coping with anticipatory medical stress

Maternal influences on children's fear and coping behaviors during a medical examination were studied in a pediatric outpatient clinic using the Dyadic Prestressor Interaction Scale (DPIS) to measure anticipatory reactions just prior to contact with the physician. Analysis of 50 mother-child dyads, including children from 4 to 10 years of age, revealed that the behaviors emitted by mother and child are likely to influence the child's ability to tolerate the medical experience. Maternal use of distraction and low rates of ignoring were associated with lower child distress and increased prosocial behaviors. Children's active exploration of the situation was more likely to occur when mothers provided their children with information, and was less likely when mothers reassured their children. Maternal reassurance of children and overt maternal agitation were associated with more maladaptive child responses. Age trends were also found in interactive patterns. Younger children were more likely to receive reassurance from mothers when they showed attachment. There was a stronger association between mother's information giving and child's exploring for children under 5 years, 9 months of age. Results supported the usefulness of the DPIS for investigation of child management techniques in this situation. Theoretical extension to attachment and stranger-approach situations was made. Suggestions for future studies to clarify the reciprocity of interactions or to determine causal direction between mother and child behaviors, as well as to evaluate the specificity or generality of these findings, were provided.     

Predicting stability and change in toddler behavior problems: contributions of maternal behavior and child gender

This study examined the stability and continuity of early-identified behavior problems and the factors associated with this stability. Children and their mothers (N=125) were seen when the children were 2 and 4 years of age. Maternal reports of child externalizing behavior and laboratory observations of child noncompliance were stable from age 2 to age 4. Early externalizing behaviors decreased over time; however, child noncompliance in the laboratory did not. Although few associations were found between maternal positive behavior and child behavior problems, maternal controlling behavior was related to increases in child behavior problems, particularly at high levels of both prior noncompliance and prior maternal control. Child noncompliance was predictive of increases in maternal controlling behavior over time.     

Mediators and Moderators of the Relation between Parental ADHD Symptomatology and the Early Development of Child ADHD and ODD Symptoms

The present study examined mediators and moderators of the relation between parental ADHD symptomatology and the development of child attention-deficit/hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD) symptoms across the preschool years. Participants included 258 (138 boys) 3-year-old children (M = 44.13 months, SD = 3.39) with and without behavior problems and their parents who took part in a 3-year longitudinal study. Maternal ADHD symptoms predicted later ADHD symptoms in children, controlling for early child symptomatology. Both family history of ADHD and paternal comorbid psychopathology predicted later child ADHD and ODD symptoms, but they did not account for the association between maternal and child ADHD symptoms. Although paternal ADHD symptoms were associated with age 3 child ADHD symptoms, they did not significantly predict later child ADHD symptoms controlling for early symptomatology. Family adversity moderated the relation between maternal ADHD and child ADHD symptoms, such that the relation between maternal and child ADHD symptoms was stronger for families with less adversity. Maternal overreactive parenting mediated the relation between maternal ADHD symptoms and later child ADHD and ODD symptoms. Our findings suggest that targeting paternal comorbid psychopathology and maternal parenting holds promise for attenuating the effects of parental ADHD on children’s ADHD.     

Father locus of control and child emotional and behavioral outcomes: a prospective study

In a prospective longitudinal study the authors examined the associations between parent locus of control of reinforcement (LOCR), measured before the birth of a child, and behavioral-emotional outcomes in that child at age 7 years. A total of 307 couples completed questionnaires regarding their emotional status and LOCR at their first prenatal care appointment. When their children turned 7 years old, teachers completed questionnaires regarding each participating child's behavior. Findings indicate significant associations between fathers' prenatal LOCR and child outcomes, particularly hyperactivity in sons. Hyperactivity and behavioral-emotional problems in girls, in contrast, were better predicted by maternal prenatal emotional distress. Results provide evidence that paternal and maternal characteristics that predate the birth of a child relate to later behavioral outcomes in that child. Implications for prevention of child psychopathology are discussed.     

The dopamine D4 receptor gene,birth weight,maternal depression,maternal attention,and the prediction of disorganized attachment at 36 months of age: A prospective gene × environment analysis

BackgroundEfforts to understand the developmental pathways for disorganized attachment reflect the importance of disorganized attachment on the prediction of future psychopathology. The inconsistent findings on the prediction of disorganized attachment from the dopamine D4 receptor (DRD4) gene, birth weight, and maternal depression as well as the evidence supporting the contribution of early maternal care, suggest the importance of exploring a gene by environment model.MethodsOur sample is from the Maternal Adversity, Vulnerability, and Neurodevelopment project; consisting of 655 mother–child dyads. Birth weight was cross-referenced with normative data to calculate birth weight percentile. Infant DRD4 genotype was obtained with buccal swabs and categorized according to the presence of the 7-repeat allele. Maternal depression was assessed with the Center for Epidemiologic Studies Depression Scale at the prenatal, 6-, 12-, and 24-month assessments. Maternal attention was measured at 6-months using a videotaped session of a 20-min non-feeding interaction. Attachment was assessed at 36-months using the Strange Situation Procedure.ResultsThe presence of the DRD4 7-repeat allele was associated with less disorganized attachment, β = −1.11, OR = 0.33, p = 0.0008. Maternal looking away frequency showed significant interactions with maternal depression at the prenatal assessment, β = 0.003, OR = 1.003, p = 0.023, and at 24 months, β = 0.004, OR = 1.004, p = 0.021, as at both time points, women suffering from depression and with frequent looking away behavior had an increased probability of disorganized attachment in their child, while those with less looking away behavior had a decreased probability of disorganized attachment in their child at 36 months.ConclusionsOur models support the contribution of biological and multiple environmental factors in the complex prediction of disorganized attachment at 36 months.     

Early Developmental Precursors of Externalizing Behavior in Middle Childhood and Adolescence

This study examined the infancy- and toddler-age precursors of children's later externalizing problem behavior. Risk constructs included suboptimal patterns of observed caregiver-child interaction and the caregiver's perception of child difficultness and resistance to control. In addition, a novel dimension of caregiver-child relationship quality, the caregiver's perception of her toddler's unresponsiveness to her, was examined as a possible precursor of children's externalizing behavior. Externalizing problem outcomes were assessed throughout the school-age period and again at age 17, using multiple informants. As toddlers, children at risk for later externalizing behavior were perceived as difficult and resistant to control, and relationships with their caregivers were relatively low in warmth and affective enjoyment. Finally, the caregiver's perception of her toddler as emotionally unresponsive to her was a consistent predictor of later externalizing behavior, suggesting that negative maternal cognitions associated with child conduct problems may begin in toddlerhood. These predictive patterns were similar for boys and girls, and with minor exceptions, generalized across different subdimensions of externalizing problem behavior. Our findings underscore the importance of the infancy and toddler periods to children's long-term behavioral adjustment, and indicate the desirability of further research into the nature of caregivers' early perceptions of child unresponsiveness.     

Dyadic Flexibility in Early Parent–Child Interactions: Relations with Maternal Depressive Symptoms and Child Negativity and Behaviour Problems

Lower levels of parent–child affective flexibility indicate risk for children's problem outcomes. This short‐term longitudinal study examined whether maternal depressive symptoms were related to lower levels of dyadic affective flexibility and positive affective content in mother–child problem‐solving interactions at age 3.5 years (N = 100) and whether these maternal and dyadic factors predicted child emotional negativity and behaviour problems at a 4‐month follow‐up. Dyadic flexibility and positive affect were measured using dynamic systems‐based modelling of second‐by‐second affective patterns during a mother–child problem‐solving task. Results showed that higher levels of maternal depressive symptoms were related to lower levels of dyadic affective flexibility, which predicted children's higher levels of negativity and behaviour problems as rated by teachers. Mothers' ratings of child negativity and behaviour problems were predicted by their own depressive symptoms and individual child factors, but not by dyadic flexibility. There were no effects of dyadic positive affect. Findings highlight the importance of studying patterns in real‐time dyadic parent–child interactions as potential mechanisms of risk in developmental psychopathology.
