Predicting cognitive-language and social growth curves from early maternal behaviors in children at varying degrees of biological risk

Stabilities of Infant Behaviors and Maternal Responses to Them

Consistency in the order of individuals in a group across substantial lengths of time-stability-is a central concept in developmental science for several reasons. Stability underscores the meaningfulness of individual differences in psychological phenomena; stability informs about the origins, nature, and overall developmental course of psychological phenomena; stability signals individual status and so affects the environment, experience, and development; stability has both theoretical and clinical implications for individual functioning; and stability helps to establish that a measure constitutes a consequential individual-differences metric. In this three-wave prospective longitudinal study (Ns = 40 infants and mothers), we examined stabilities of individual variation in multiple infant behaviors and maternal responses to them across infant ages 10, 14, and 21 months. Medium to large effect size stabilities in infant behaviors and maternal responses emerged, but both betray substantial amounts of unshared variance. Documenting the ontogenetic trajectories of infant behaviors and maternal responses helps to elucidate the nature and structure of early human development.

Do Helpful Mothers Help? Effects of Maternal Scaffolding and Infant Engagement on Cognitive Performance

Infants are highly social and much early learning takes place in a social context during interactions with caregivers. Previous research shows that social scaffolding - responsive parenting and joint attention - can confer benefits for infants' long-term development and learning. However, little previous research has examined whether dynamic (moment-to-moment) adaptations in adults' social scaffolding are able to produce immediate effects on infants' performance. Here we ask whether infants' success on an object search task is more strongly influenced by maternal behavior, including dynamic changes in response behavior, or by fluctuations in infants' own engagement levels. Thirty-five mother-infant dyads (infants aged 10.8 months, on average) participated in an object search task that was delivered in a naturalistic manner by the child's mother. Measures of maternal responsiveness (teaching duration; sensitivity) and infant engagement (engagement score; visual attention) were assessed. Mothers varied their task delivery trial by trial, but neither measure of maternal responsiveness significantly predicted infants' success in performing the search task. Rather, infants' own level of engagement was the sole significant predictor of accuracy. These results indicate that while parental scaffolding is offered spontaneously (and is undoubtedly crucial for development), in this context children's endogenous engagement proved to be a more powerful determinant of task success. Future work should explore this interplay between parental and child-internal factors in other learning and social contexts.

Friendship and social functioning following early institutional rearing: The role of ADHD symptoms

Early institutional rearing is associated with increased risk for subsequent peer relationship difficulties, but the underlying mechanisms have not been identified. Friendship characteristics, social behaviors with peers, normed assessments of social problems, and social cue use were assessed in 142 children (mean age = 10.06, SD = 2.02; range 7-13 years), of whom 67 were previously institutionalized (PI), and 75 were raised by their biological families. Anxiety and attention-deficit/hyperactivity disorder (ADHD) symptoms, often elevated among PI children, were examined as potential mediators of PI status and baseline social functioning and longitudinal follow-ups (2 and 4 years later). Twenty-seven percent of PI children fell above the Child Behavior Checklist Social Problems cutoff. An examination of specific social behaviors with peers indicated that PI and comparison children did not differ in empathic concern or peer social approach, though parents were more likely to endorse aggression/overarousal as a reason that PI children might struggle with friendships. Comparison children outperformed PI children in computerized testing of social cue use learning. Finally, across these measures, social difficulties exhibited in the PI group were mediated by ADHD symptoms with predicted social problems assessed 4 years later. These findings show that, when PI children struggle with friendships, mechanisms involving attention and behavior regulation are likely contributors.

The importance of early life touch for psychosocial and moral development

One of the primary means of communicating with a baby is through touch. Nurturing physical touch promotes healthy physiological development in social mammals, including humans. Physiology influences wellbeing and psychosocial functioning. The purpose of this paper is to explore the connections among early life positive and negative touch and wellbeing and sociomoral development. In study 1, mothers of preschoolers (n = 156) reported their attitudes toward positive/negative touch and on their children's wellbeing and sociomoral outcomes, illustrating moderate to strong positive correlations between positive touch attitudes and children's sociomoral capacities and orientations and negative correlations with psychopathology. In study 2, we used an existing longitudinal dataset, with at-risk mothers (n = 682) and their children to test touch effects on moral capacities and social behaviors in early life. Results demonstrated moderate to strong relationships between positive/negative touch and concurrent child behavioral regulation and positive correlations between low corporal punishment and child sociomoral outcomes. In a third study with adults (n = 607), we found significant mediation processes connecting retrospective reports of childhood touch to adult moral orientation through attachment security, mental health, and moral capacities. In general across studies, more affectionate touch and less punishing touch were positively associated with wellbeing and development of moral capacities and engaged moral orientation.

Parents Influence the Visual Learning Environment Through Children's Manual Actions

The present research studied children in the second year of life (N = 29, M_age  = 21.14 months, SD = 2.64 months) using experimental manipulations within and between subjects to show that responsive parental influence helps children have more frequent sustained object holds with fewer switches between objects compared to when parents are either not involved or over-involved. Regardless of parental involvement, sustained holds were visually rich, based on the size, centeredness, and dominance of the held object relative to other objects. These findings are important because they suggest not only that the child's body creates visually rich scenes across play contexts but also that a responsive parent can increase the frequency of these visually rich and informative moments.

Effects of Gestational Age and Early Parenting on Children's Social Inhibition at 6 Years

Preterm birth (<37 weeks' gestation) has been associated with problems in social functioning. Whether social inhibition is specifically related to preterm birth and whether early parenting may protect against social inhibition difficulties is unknown. To explore effects of gestational age and early parent-infant relationships on social inhibition, 1314 children born at 26-41 weeks gestational age were studied as part of the prospective Bavarian Longitudinal Study. Early parent-infant relationship quality was assessed postnatally with the parent-infant relationship index. Social inhibition was assessed at age 6 years using an experimental procedure, in which nonverbal and verbal responses were coded into social inhibition categories (disinhibited, normally responsive, inhibited). Multinomial logistic regressions indicated that children with lower gestational age showed more socially disinhibited (nonverbal: OR = 1.27 [95% CI = 1.17-1.40], verbal: OR = 1.23 [95% CI 1.13-1.35]) and inhibited (nonverbal: OR = 1.21 [95% CI = 1.11-1.32], verbal: OR = 1.11 [95% CI = 1.01-1.21]) responses. Good early parent-infant relationships were associated with less verbal disinhibition (OR = 0.70 [95% CI = 0.52-0.93]). Findings suggest that children with lower gestational age are at greater risk to be both socially inhibited and disinhibited. Early parenting affected risk of abnormal social responses. Supporting early parent-infant relationships may reduce preterm children's risk for social difficulties.

Using pupil dilation, eye-blink rate, and the value of mother to investigate reward learning mechanisms in infancy

The brain is adapted to learn from interactions with the environment that predict or enable the procurement of rewards (Schultz, 2010). For infants, the main caregiver (often the mother) is most associated with primary biological rewards such as food and warmth, as well as the most likely provider of emotional and social rewards such as comfort and responsiveness. In this study we capitalize on the reward value of mother to examine reward learning mechanisms in infancy using multiple eye-tracking measures. Converging lines of research have demonstrated links between reward-related striatal dopamine activity and measurable changes in spontaneous eye-blink rate (EBR) and pupil dilation (Eckstein et al., 2017). We presented 7-month-old infants with video stimuli that parametrically increased in social-emotional value (male stranger, female stranger, mother) or in visual attention value (static image, slowed silent cartoon, dynamic cartoon). After establishing infants’ baseline responses to these stimuli, we paired the videos with arbitrary shape cues in an associative learning task. Infants showed superior learning from their own mother’s video and a heightened anticipatory arousal response to the mother-associated cue following learning. Both learning measures were predicted by infants’ baseline EBR to their mother’s video, providing the first evidence of reward learning and transfer in human infants.

The Interplay Between Early Father Involvement and Neonatal Medical Risk in the Prediction of Infant Neurodevelopment

The current study examines the association between early father involvement and infant neurodevelopment, and whether neonatal medical risk moderates this association. Data from approximately 6000 fathers and their children were obtained from the Early Childhood Longitudinal Study: Birth Cohort (ECLS-B). Hierarchical regression was employed to analyze the data. The findings reveal that the association between early father involvement and infant neurodevelopment is contingent on both the timing of involvement (i.e., prenatal/perinatal or infancy) and offspring medical status at birth. The neurodevelopment of medically at-risk neonates was enhanced when fathers were involved during the gestational period and at the time of their birth. This relationship was not detected, however, in the case of infants who did not experience medical risks as neonates. Neonatal medical risk appears to be an important moderating factor in the link between father involvement during pregnancy and childbirth and infant neurodevelopment. Practitioners should continue to make efforts to involve fathers during gestation and childbirth. The findings of the present study suggest that doing so may protect against neurodevelopmental delays in neonates with medical risks.

Maternal and infant affect at 4 months predicts performance and verbal IQ at 4 and 7 years in a diverse population

Using existing longitudinal data from 570 infants in the Maternal Lifestyle Study, we explored the predictive value of maternal and infant affect and maternal vocalizations during 2 minutes of face-to-face interactions at 4 months on IQ scores at 4.5 and 7 years. After controlling for demographic factors, maternal depression, and prenatal drug exposure, maternal positive affect and maternal positive vocalizations emerged as predictors of both verbal and performance IQ at 4.5 and 7 years. Although infant positive affect during the interaction with the mother was not predictive of these outcome measures, infant positive affect towards an examiner predicted verbal but not performance IQ at 4.5 years. These results suggest that maternal positive affect may index emotional engagement in interaction that facilitates both verbal and nonverbal cognitive development, while infant social positive affect is specifically related to the acquisition of verbal reasoning abilities. These findings are significant because they are based on a discrete snapshot of observable behavior in infancy (just 2 minutes of interaction), because they extend the range of maternal behaviors and characteristics known to support positive developmental outcomes, and because they are derived from high-risk infants where prevention efforts may be beneficial. Potential mechanisms for these associations are discussed, as are the clinical implications for identifying dyads most in need of targeted interventions.

Observed parent behaviors as time-varying moderators of problem behaviors following traumatic brain injury in young children

Parent behaviors moderate the adverse consequences of pediatric traumatic brain injury (TBI); however, it is unknown how these moderating effects change over time. This study examined the moderating effect of observed parent behaviors over time since injury on the relation between TBI and behavioral outcomes. Participants included children, ages 3-7 years, hospitalized for moderate (n = 52) or severe (n = 20) TBI or orthopedic injury (OI; n = 95). Parent-child dyads were videotaped during structured task and free play conditions, and parents completed child behavior ratings. Linear mixed models using a lagged, time-varying moderator analysis examined the relationship of observed parent behaviors at the baseline, 6-month, and 12-month assessments to child behavior problems at 6 months, 12 months, and 18 months postinjury, after controlling for preinjury levels of child behavior problems. The effect of TBI on behavior was exacerbated by less favorable parent behaviors, and buffered by more favorable parent behaviors, in children with severe TBI over the first 12 months postinjury. By 18 months postinjury, however, the moderating effect of parent behaviors diminished, such that children with severe TBI showed more behavior problems relative to children with moderate TBI or OI regardless of parent behaviors or in response to parent behaviors that were initially protective. The results suggest that the moderating effects of the family environment are complex and likely vary in relation to both recovery and developmental factors, with potentially important implications for targets and timing of intervention.

Seven Years Cognitive Functioning and Early Assessment in Extremely Low Birth Weight Children

Infants born preterm are at high risk for the onset of cognitive dysfunctions at school age. The aim of this study was to investigate the association between early neurodevelopmental assessment and the risk of adverse cognitive outcome in extremely low birth weight children. We enrolled all newborns (January 2002 – April 2007) consecutively admitted to our Institution, with a birthweight < 1000 g. Exclusion criteria were genetic abnormalities, severe neurofunctional impairment, and/or neurosensory disabilities. Ninety-nine children were assessed at 1 year of corrected age using the Griffiths Mental Development Scales Revised. The same children were re-assessed at school age through the Wechsler Intelligence Scale for Children. Children with impaired Griffiths General Quotient (i.e., <1 SD) at 1 year of corrected age showed a significantly lower Full Scale Intelligence Quotient at 7 years of chronological age when compared to children who scored in the normal range at 1 year (p < 0.01). Considering the Griffiths Sub-quotients separately, a poor score in the Performance or in the Personal-Social Sub-quotients at 1 year was associated with significantly worse cognitive outcomes both in the Verbal and in the Performance Intelligence Quotients at 7 years (p < 0.01 and p < 0.05, respectively). A score <1 SD in the Locomotor or in the Eye and Hand Coordination Sub-quotients were specifically associated with poorer Performance or Verbal Intelligence Quotients, respectively (p < 0.05). Our findings suggest that a poor score on the Griffiths Scales at 1 year is associated with a higher risk of cognitive impairment at school age. Larger confirmation studies are needed.

Family Interactions and Developmental Risk Associated With Early Cognitive Delay: Influences on Children's Behavioral Competence

Family interactions can be important contributors to the development of child psychopathology, yet the mechanisms of influence are understudied, particularly for populations at risk. This prospective longitudinal study addresses differences in whole family interactions in 194 families of young children with and without early-identified developmental risk associated with cognitive delay. The influence of family interactions on children's later externalizing behaviors, internalizing behaviors, and social skills was examined, and developmental risk was tested as a potential moderator of these relations. Results indicated that the presence of cognitive developmental risk was linked to higher levels of family control than in families of typically developing children, but groups did not differ on dimensions of cohesion, warmth, organization, or conflict. Observed cohesion and organization were associated with better social skills for all children, regardless of risk status. Significant interactions emerged, indicating that higher levels of conflict and control were associated with higher levels of behavior problems, but only for families of typically developing children. These findings underscore the importance of family-level assessment in understanding the development of children's behavior and suggest the need for deeper analysis of the nuances of family process over time.

Risk and resilience in preterm children at age 6

Children born preterm are at risk for experiencing significant deleterious developmental outcomes throughout their childhood and adolescence. However, individual variation and resilience are hallmarks of the preterm population. The present study examined pathways to resilience across multiple domains (e.g., social activities, peer relations, attention-deficit/hyperactivity disorder symptomology, externalizing and internalizing behavior, and sleep quality) as children born preterm reached school age. The study also examined early child and family predictors of resilience. Using a prospective longitudinal design, 173 infants born preterm and without significant neurological complications were assessed at five time points: neonatal intensive care unit discharge, 9 months, 16 months, 24 months, and 6 years. Three pathways of adaptation emerged at 6 years: children who were resilient, those who remained at-risk, and children who exhibited significant difficulties. Resilient children were less likely to have experienced negative parenting at 9 and 16 months, more likely to delay gratification at 24 months, and more likely to experience neonatal health complications than nonresilient children.

Cumulative biomedical risk and social cognition in the second year of life: prediction and moderation by responsive parenting

At 18 months, children show marked variability in their social-cognitive skill development, and the preponderance of past research has focused on constitutional and contextual factors in explaining this variability. Extending this literature, the current study examined whether cumulative biomedical risk represents another source of variability in social cognition at 18 months. Further, we aimed to determine whether responsive parenting moderated the association between biomedical risk and social cognition. A prospective community birth cohort of 501 families was recruited at the time of the child's birth. Cumulative biomedical risk was measured as a count of 10 prenatal/birth complications. Families were followed up at 18 months, at which point social-cognitive data was collected on children's joint attention, empathy, cooperation, and self-recognition using previously validated tasks. Concurrently, responsive maternal behavior was assessed through observational coding of mother-child interactions. After controlling for covariates (e.g., age, gender, child language, socioeconomic variables), both cumulative biomedical risk and maternal responsivity significantly predicted social cognition at 18 months. Above and beyond these main effects, there was also a significant interaction between biomedical risk and maternal responsivity, such that higher biomedical risk was significantly associated with compromised social cognition at 18 months, but only in children who experienced low levels of responsive parenting. For those receiving comparatively high levels of responsive parenting, there was no apparent effect of biomedical risk on social cognition. This study shows that cumulative biomedical risk may be one source of inter-individual variability in social cognition at 18 months. However, positive postnatal experiences, particularly high levels of responsive parenting, may protect children against the deleterious effects of these risks on social cognition.

Consistency of maternal cognitions and principles across the first five months following preterm and term deliveries

•

Consistency in group level (continuity) and individual level (stability) was examined longitudinally for caregiving principles (structure and attunement) and cognitions (categorical thinking, perspectivist thinking, complexity of thought) in mothers of preterm and term infants from birth to 5 months old.

•

Attunement was continuous and stable in mothers of preterm and term infants.

•

Structure was continuous in both groups but stable only in mothers of term infants.

•

Complexity of thought was continuous in both groups, perspectivist thinking increased in both groups but only for first-time mothers, and categorical thinking increased only in mothers of preterm infants.

•

Categorical thinking, perspectivist thinking, and complexity of thought were stable in mothers of both preterm and term infants.

The aims of this study were to examine and compare the development of parenting cognitions and principles in mothers following preterm and term deliveries. Parenting cognitions about child development, including thinking that is restricted to single causes and single outcomes (categorical thinking) and thinking that takes into account multiple perspectives (perspectivist thinking), have been shown to relate to child outcomes. Parenting principles about using routines (structure) or infant cues (attunement) to guide daily caregiving have been shown to relate to caregiving practices. We investigated the continuity and stability of parenting cognitions and principles in the days following birth to 5 months postpartum for mothers of infants born term and preterm. All parenting cognitions were stable across time. Categorical thinking increased at a group level across time in mothers of preterm, but not term, infants. Perspectivist thinking increased at a group level for first-time mothers (regardless of birth status) and tended to be lower in mothers of preterm infants. Structure at birth did not predict later structure (and so was unstable) in mothers of preterm, but not term, infants and neither group changed in mean level across time. Attunement was consistent across time in both groups of mothers. These results indicate that prematurity has multiple, diverse effects on parenting beliefs, which may in turn influence maternal behavior and child outcomes.

Maternal directiveness in childhood survivors of acute lymphoblastic leukemia

Parental intrusiveness is associated with internalizing problems in healthy children. Given the unique demands that childhood cancer places on parents, it is important to determine whether intrusiveness operates differently in survivors of childhood cancer. The current study tested whether cancer survivorship moderates the relation between maternal directiveness-one aspect of intrusiveness-and children's internalizing problems. Survivors (7-12 years old) of acute lymphoblastic leukemia (ALL) (n = 25) and their mothers, and healthy controls (n = 22) and their mothers engaged in parent-child interactions. Mothers completed a measure of children's psychosocial adjustment, and observations of 10-min parent-child interactions were obtained. Cancer survivorship moderated the relation between directiveness and children's withdrawn/depressed symptoms. Maternal directiveness was associated with increased withdrawn/depressed symptoms for children in the control group. This association was not significant for survivors of ALL. Findings suggest that childhood cancer may alter the context in which children experience maternal directiveness.

Interactive behaviors of American Indian mothers and their premature infants

The interactive behaviors of 17 American Indian mothers and their premature infants and selected maternal and infant factors affecting those behaviors were measured using naturalistic observation and the Home Observation for Measurement of the Environment (HOME) Inventory at 3, 6, and 12 months corrected infant age. The frequency of some maternal behaviors changed over the first 12 months. Mothers spent less time holding, looking at, touching, and interacting with their premature infants and more time uninvolved as the infant aged. Maternal education and infant illness severity were associated with mother-infant interactive behaviors and HOME Inventory scores. These findings emphasize the importance of maternal and infant factors affecting the interactions between American Indian premature infants and their mothers.

Maternal warm responsiveness and negativity following traumatic brain injury in young children

PURPOSE/OBJECTIVE

To understand how traumatic brain injury (TBI) affects maternal warm responsiveness and negativity over the first 12 months following injury.

METHOD/DESIGN

We used a concurrent cohort research design to examine dyadic interactions in young children with a TBI (n = 78) and a comparison group of young children with orthopedic injuries (OI; n = 112) and their families during the initial weeks following injury (i.e., baseline) and at two follow-up periods (approximately 6 and 12 months later). Trained raters coded videotaped interactions during a free play and structured teaching task for maternal warm responsiveness and negativity.

RESULTS

Mothers in the complicated mild/moderate TBI group, but not those in the severe TBI group, exhibited significantly lower levels of maternal warm responsiveness than mothers in the OI group. However, these differences were observed only at baseline during free play and only at baseline and 6 months postinjury during the structured teaching task, suggesting diminishing adverse effects of complicated mild/moderate TBI on parenting over time postinjury. Analysis failed to reveal group differences in maternal negativity at any of the assessments. Across groups, lower socioeconomic status (SES) was associated with lower levels of warm responsiveness and higher levels of negativity.

CONCLUSIONS/IMPLICATIONS

These findings, though preliminary, indicate possible alterations in mother-child interactions in the months following a TBI.

Differential ethnic associations between maternal flexibility and play sophistication in toddlers born very low birth weight

Children born very low birth weight (<1500 g, VLBW) are at increased risk for developmental delays. Play is an important developmental outcome to the extent that child's play and social communication are related to later development of self-regulation and effective functional skills, and play serves as an important avenue of early intervention. The current study investigated associations between maternal flexibility and toddler play sophistication in Caucasian, Spanish speaking Hispanic, English speaking Hispanic, and Native American toddlers (18-22 months adjusted age) in a cross-sectional cohort of 73 toddlers born VLBW and their mothers. We found that the association between maternal flexibility and toddler play sophistication differed by ethnicity (F(3,65) = 3.34, p = .02). In particular, Spanish speaking Hispanic dyads evidenced a significant positive association between maternal flexibility and play sophistication of medium effect size. Results for Native Americans were parallel to those of Spanish speaking Hispanic dyads: the relationship between flexibility and play sophistication was positive and of small-medium effect size. Findings indicate that for Caucasians and English speaking Hispanics, flexibility evidenced a non-significant (negative and small effect size) association with toddler play sophistication. Significant follow-up contrasts revealed that the associations for Caucasian and English speaking Hispanic dyads were significantly different from those of the other two ethnic groups. Results remained unchanged after adjusting for the amount of maternal language, an index of maternal engagement and stimulation; and after adjusting for birth weight, gestational age, gender, test age, cognitive ability, as well maternal age, education, and income. Our results provide preliminary evidence that ethnicity and acculturation may mediate the association between maternal interactive behavior such as flexibility and toddler developmental outcomes, as indexed by play sophistication. Addressing these association differences is particularly important in children born VLBW because interventions targeting parent interaction strategies such as maternal flexibility must account for ethnic-cultural differences in order to promote toddler developmental outcomes through play paradigms.

The relationship of parental warm responsiveness and negativity to emerging behavior problems following traumatic brain injury in young children

Parenting behaviors play a critical role in the child's behavioral development, particularly for children with neurological deficits. This study examined the relationship of parental warm responsiveness and negativity to changes in behavior following traumatic brain injury (TBI) in young children relative to an age-matched cohort of children with orthopedic injuries (OI). It was hypothesized that responsive parenting would buffer the adverse effects of TBI on child behavior, whereas parental negativity would exacerbate these effects. Children, ages 3-7 years, hospitalized for TBI (n = 80) or OI (n = 113), were seen acutely and again 6 months later. Parent-child dyads were videotaped during free play. Parents completed behavior ratings (Child Behavior Checklist; T. M. Achenbach & L. A. Rescorla, 2001) at both visits, with baseline ratings reflecting preinjury behavior. Hypotheses were tested using multiple regression, with preinjury behavior ratings, race, income, child IQ, family functioning, and acute parental distress serving as covariates. Parental responsiveness and negativity had stronger associations with emerging externalizing behaviors and attention-deficit/hyperactivity disorder symptoms among children with severe TBI. Findings suggest that parenting quality may facilitate or impede behavioral recovery following early TBI. Interventions that increase positive parenting may partially ameliorate emerging behavior problems.

Attention problems and language development in preterm low-birth-weight children: cross-lagged relations from 18 to 36 months

BACKGROUND

Research has highlighted a series of persistent deficits in cognitive ability in preterm low-birth-weight children. Language and attention problems are among these deficits, although the nature of the relation between attention and language in early development is not well known. This study represents a preliminary attempt to shed light on the relations between attention problems and language development in preterm low-birth-weight children.

METHODS

The aim of this study was to analyse reciprocal influences between language and attention problems from 18 to 36 months. We used maternal reports on attention problems and language ability referring to a sample of 1288 premature low-birth-weight infants, collected as part of the Norwegian Mother and Child Cohort Study (MoBa). A sample of children born full-term was used as the control group (N = 37010). Cross-lagged panel analyses were carried out to study reciprocal influences between attention problems and language.

RESULTS

Language ability at 18 months did not significantly predict attention problems at 36 months, adjusting for attention problems at 18 months. Attention problems at 18 months significantly predicted changes in language ability from 18 to 36 months, pointing to a precursor role of attention in relation to language in children born preterm. Gender, age corrected for prematurity, and mother's education emerged as important covariates.

CONCLUSIONS

Preliminary evidence was found for a precursor role of early attention problems in relation to language in prematurity. This finding can contribute to a better understanding of the developmental pathways of attention and language and lead to better management of unfavourable outcomes associated with co-morbid attention and language difficulties.

Depression among a sample of first-time adolescent and adult mothers

PROBLEM

Little is known about the rates, correlates, and consequences of depression among a sample of first-time mothers.

METHODS

Four-site prospective study of the first 3 years of life among first children born to first-time mothers, including adolescent (N= 396), lower- (N= 169), and higher-resource adult (N= 117). Mothers were administered the Beck Depression Inventory prenatally and 6 months postpartum. Measures of maternal and infant behaviors were taken at 8 months.

FINDINGS

Adolescent mothers displayed higher prenatal and 6-month rates of depression than lower- and higher-resource adult mothers, with significantly more adolescent mothers "consistently" depressed at the two time points than lower- and higher-resource adult mothers. Further, adolescent mothers were significantly more likely to become depressed after their babies were born than lower- or higher-resource adult mothers. Depression was negatively related to parenting practices and babies' behavior. As depression increased, mothers scored less favorably in maternal warmth and sensitivity, contingent responsiveness, and general verbalness; children scored less favorably in warmth seeking toward their mothers.

CONCLUSION

Findings signify the need for counseling and nurse-based intervention and prevention services geared at preparing pregnant adolescents for motherhood.

Genetic liability, environment, and the development of fussiness in toddlers: the roles of maternal depression and parental responsiveness

Using a longitudinal, prospective adoption design, the authors of this study examined the effects of the environment (adoptive parents' depressive symptoms and responsiveness) and genetic liability of maternal depression (inferred by birth mothers' major depressive disorder [MDD]) on the development of fussiness in adopted children between 9 and 18 months old. The sample included 281 families linked through adoption, with each family including 4 individuals (i.e., adopted child, birth mother, adoptive father and mother). Results showed that adoptive mothers' depressive symptoms when their child was 9 months old were positively associated with child fussiness at 18 months. A significant interaction between birth mothers' MDD and adoptive mothers' responsiveness indicated that children of birth mothers with MDD showed higher levels of fussiness at 18 months when adoptive mothers had been less responsive to the children at 9 months. However, in the context of high levels of adoptive mothers' responsiveness, children of birth mothers with MDD did not show elevated fussiness at 18 months. Findings are discussed in terms of gene-environment interactions in the intergenerational risk transmission of depression.

Dynamic infant-parent affect coupling during the face-to-face/still-face

We examined dynamic infant-parent affect coupling using the Face-to-Face/Still-Face (FFSF). The sample included 20 infants whose older siblings had been diagnosed with Autism Spectrum Disorders (ASD-sibs) and 18 infants with comparison siblings (COMP-sibs). A series of mixed effects bivariate autoregressive models was used to represent the self-regulation and interactive dynamics of infants and parents during the FFSF. Significant bidirectional affective coupling was found between infants and parents, with infant-to-parent coupling being more prominent than parent-to-infant coupling. Further analysis of within-dyad dynamics revealed ongoing changes in concurrent infant-parent linkages both within and between different FFSF episodes. The importance of considering both inter- and intradyad differences is discussed.

A Caregiver-Child Social/Emotional and Relationship Rating Scale (CCSERRS)

This paper reports the construction and pilot reliability, validity, and psychometric properties of a new caregiver-child rating scale that emphasizes caregiver-child social-emotional interactions and relationships. While the scale was developed and studied in the context of orphanages for young children, it potentially could be used in non-residential early care and education settings as well as for parent-child interactions in the home. The intent was to assess a few dimensions that comprehensively cover the range of caregiver-child social-emotional interactions and relationships but could be administered in a relatively short period of time in a variety of situations and would not require extensive coder training, manuals, or materials. Results showed that the scale can be reliably administered even using observation periods as short as five minutes, reliability was replicated over seven different coders working in three different orphanages, and ratings of caregivers were similar across different types of caregiving activities (i.e., feeding, dressing/bathing, free play) and for caregivers attending to children birth to 4 and 4 to 8 yrs. of age. In the orphanage context, factor analyses showed the scale primarily reflects caregiver-child mutual engagement and relationship with subordinate components of caregiver punitiveness and caregiver- vs. child-directed behaviors and intrusiveness.

Growth mixture modeling of academic achievement in children of varying birth weight risk

The extremes of birth weight and preterm birth are known to result in a host of adverse outcomes, yet studies to date largely have used cross-sectional designs and variable-centered methods to understand long-term sequelae. Growth mixture modeling (GMM) that utilizes an integrated person- and variable-centered approach was applied to identify latent classes of achievement from a cohort of school-age children born at varying birth weights. GMM analyses revealed 2 latent achievement classes for calculation, problem-solving, and decoding abilities. The classes differed substantively and persistently in proficiency and in growth trajectories. Birth weight was a robust predictor of class membership for the 2 mathematics achievement outcomes and a marginal predictor of class membership for decoding. Neither visuospatial-motor skills nor environmental risk at study entry added to class prediction for any of the achievement skills. Among children born preterm, neonatal medical variables predicted class membership uniquely beyond birth weight. More generally, GMM is useful in revealing coherence in the developmental patterns of academic achievement in children of varying weight at birth and is well suited to investigations of sources of heterogeneity.

Parent-Child Interactions During the Initial Weeks Following Brain Injury in Young Children

OBJECTIVE

To understand how traumatic brain injury (TBI) affects parent-child interactions acutely following injury.

PARTICIPANTS

Young children hospitalized for TBI (n = 80) and orthopedic injuries (OI; n = 113).

METHOD

Raters coded videotaped interactions during free play and structured tasks for parental warmth/responsiveness and negativity and child warmth, behavior regulation, and cooperation. Raters also counted parental directives, critical/restricting statements, and scaffolds.

RESULTS

Parents of children with TBI exhibited less warm responsiveness and made more directive statements during a structured task than parents in the OI group. Children with TBI displayed less behavior regulation than children with OI. Parental warm responsiveness was more strongly related to child cooperativeness in the OI group than in the TBI group. Child behavior also mediated group differences in parental responsiveness and directiveness. TBI accounted for as much variance in parental behaviors as or more than did sociodemographic factors.

CONCLUSION

TBI-related changes in child behavior may negatively influence parent-child interactions and disrupt the reciprocity between parent and child.

Neighborhood and Family Influences on Educational Attainment: Results from the Ontario Child Health Study Follow-Up 2001

This study uses multilevel models to examine longitudinal associations between contextual influences (neighborhood and family) assessed in 1983 in a cohort of 2,355 children, 4-16 years of age, and educational attainment in 2001. Variation in educational attainment in 2001 attributable to between-neighborhood and between-family differences was 8.17% and 36.88%, respectively. The final model explained 33.64% of the variance in educational attainment, with unique variances of 14.53% for neighborhood and family-level variables combined versus 10.94% for child-level variables. Among the neighborhood and family-level variables, indicators of status (5.29%) versus parental capacity/family process (4.03%) made comparable predictions to attainment while children from economically disadvantaged families did not benefit educationally from living in more affluent areas.
