Developmental trajectories of late preterm infants and predictors of academic performance.

BACKGROUND: The trajectories of late preterm development from infancy to kindergarten reading and math, and predictors of academic resilience and risk are unknown. METHODS: Sample included 1200 late preterm infants (LPIs) from the Early Childhood Longitudinal Study, Birth Cohort. Objective measurements of development at 9 and 24 months (Bayley-SFR) and reading and math academic achievement at preschool and kindergarten were standardized; trajectories of late preterm development from 9 months to kindergarten reading and math were identified using latent class growth analysis. Multinomial logistic regression [aOR, 95% CI] identified predictors of academic resilience and risk. RESULTS: Four trajectory groups were observed for reading and three for math. More optimal trajectories (in reading and math) and academic resilience were associated with experiencing sensitive parenting and preschool attendance. Suboptimal (at-risk) trajectories (in reading or math) and an increased odds of academic risk were associated with

Early parenting, represented family relationships, and externalizing behavior problems in children born preterm.

Through assessment of 173 preterm infants and their mothers at hospital discharge and at 9, 16, 24, 36, and 72 months, the study examined early parenting, attachment security, effortful control, and children's representations of family relationships in relation to subsequent externalizing behavior problems. Less intrusive early parenting predicted more secure attachment, better effortful control skills, and fewer early behavior problems, although it did not directly relate to the structural or content characteristics of children's represented family relationships. Children with higher effortful control scores at 24 months had more coherent family representations at 36 months. Moreover, children who exhibited less avoidance in their family representations at 36 months had fewer mother-reported externalizing behavior problems at 72 months. The study suggests that early parenting quality and avoidance in children's represented relationships are important for the development of externalizing behavior problems in children born preterm.

Relationship processes and resilience in children with incarcerated parents.

Children with incarcerated parents are at risk for a variety of problematic outcomes, yet research has rarely examined protective factors or resilience processes that might mitigate such risk in this population. In this volume, we present findings from five new studies that focus on child- or family-level resilience processes in children with parents currently or recently incarcerated in jail or prison. In the first study, empathic responding is examined as a protective factor against aggressive peer relations for 210 elementary school age children of incarcerated parents. The second study further examines socially aggressive behaviors with peers, with a focus on teasing and bullying, in a sample of 61 children of incarcerated mothers. Emotion regulation is examined as a possible protective factor. The third study contrasts children's placement with maternal grandmothers versus other caregivers in a sample of 138 mothers incarcerated in a medium security state prison. The relation between a history of positive attachments between mothers and grandmothers and the current cocaregiving alliance are of particular interest. The fourth study examines coparenting communication in depth on the basis of observations of 13 families with young children whose mothers were recently released from jail. Finally, in the fifth study, the proximal impacts of a parent management training intervention on individual functioning and family relationships are investigated in a diverse sample of 359 imprisoned mothers and fathers. Taken together, these studies further our understanding of resilience processes in children of incarcerated parents and their families and set the groundwork for further research on child development and family resilience within the context of parental involvement in the criminal justice system.

Sleep and Attachment in Preterm Infants.

Infants born preterm are at elevated risk for social emotional difficulties. However, factors contributing to this risk are largely understudied. Within the present study, we explored infant sleep as a biosocial factor that may play a role in infant social emotional development. Within a prospective longitudinal design, we examined parent-reported sleep patterns and observed parenting quality as predictors of infant-mother attachment in 171 infants born preterm. Using structural equation modeling, we examined main effect and moderator models linking infant sleep patterns and parenting with attachment security. Sleep patterns characterized by more daytime sleep and positive/responsive parenting predicted infant attachment security. Parent-reported nighttime sleep patterns were unrelated to attachment in this sample of infants born preterm. These results indicate that daytime sleep and parenting quality may be important for emerging attachment relationships in infants born preterm.

Preterm infants who are prone to distress: differential effects of parenting on 36-month behavioral and cognitive outcomes.

BACKGROUND: The differential susceptibility (DS) model suggests that temperamentally prone-to-distress infants may exhibit adverse outcomes in negative environments but optimal outcomes in positive environments. This study explored temperament, parenting, and 36-month cognition and behavior in preterm infants using the DS model. We hypothesized that temperamentally prone to distress preterm infants would exhibit more optimal cognition and fewer behavior problems when early parenting was positive; and less optimal cognition and more behavior problems when early parenting was less positive. METHODS: Participants included 109 preterm infants (gestation <37 weeks) and their mothers. We assessed neonatal risk and basal vagal tone in the neonatal intensive care unit; infant temperament and parenting interactions at 9 months post-term; and child behavior and cognitive skills at 36 months post-term. Hierarchical regression analyses tested study hypotheses. RESULTS: Temperamentally prone-to-distress infants exhibited more externalizing problems if they experienced more critical parenting at 9 months (ß = -.20, p < 0.05) but fewer externalizing problems with more positive parenting. Similarly, variations in maternal positive affect (ß = .25, p < .01) and intrusive behaviors (ß = .23, p < .05) at 9 months predicted 36-month cognition at high but not at low levels of infant temperamental distress. Higher basal vagal tone predicted fewer externalizing problems (ß = -.19, p < .05). CONCLUSIONS: Early parenting behaviors relate to later behavior and development in preterm infants who are temperamentally prone to distress, and neonatal basal vagal tone predicts subsequent externalizing behaviors. These findings suggest that both biological reactivity and quality of caregiving are important predictors for later outcomes in preterm infants and may be considered as foci for developmental surveillance and interventions.

Maternal jail time, conviction, and arrest as predictors of children's 15-year antisocial outcomes in the context of a nurse home visiting program.

Data from the Nurse-Family Partnership intervention program were analyzed to compare the "selection" versus "unique" effects of maternal jail time on adolescent antisocial and health risk outcomes. Data from 320 women and their firstborn children were available from the prenatal, birth, and 15-year assessments. Consistent with a selection perspective, prenatal and demographic risks directly and indirectly related to many adolescent antisocial outcomes. Maternal conviction and arrest were also associated with adolescent contact with the criminal justice system and health risk behaviors. Maternal jail time predicted whether or not children had ever been stopped by police, sent to youth corrections, or run away from home. However, these associations were not significant after controlling for prenatal risk factors and maternal conviction and arrest. The results highlight the importance of maternal criminality and other risk factors in children's environments, including prenatal variables.

COMPLIANCE, OPPOSITION, AND BEHAVIOR PROBLEMS IN TODDLERS BORN PRETERM OR LOW BIRTHWEIGHT.

Although children born preterm or low birth weight (PT LBW) are more likely to exhibit behavior problems compared to children born at term, developmental and family processes associated with these problems are unclear. We examined trajectories of maternal depressive symptoms in relation to toddler compliance and behavior problems in families with PT LBW infants. A total of 177 infants (93 boys, 84 girls) and their mothers enrolled in the study during the infant's NICU stay. Data were collected at five time points across 2 years. Assessments of maternal depressive symptoms were conducted at all time points, and toddler compliance and opposition to maternal requests and behavior problems were assessed at 2 years. Toddlers born earlier with more health problems to mothers whose depressive symptoms increased over time exhibited the most opposition to maternal requests during a cleanup task at 24 months, consistent with multiple risk models. Mothers with elevated depression symptoms reported more behavior problems in their toddlers. The study has implications for family-based early intervention programs seeking to identify PT LBW infants at highest risk for problem behaviors.

Do mothers' play behaviors moderate the associations between socioeconomic status and 24-month neurocognitive outcomes of toddlers born preterm or with low birth weight?

OBJECTIVE: We examined whether neonatal risks and maternal scaffolding (i.e., task changes and flexibility) during a 16-month post-term play interaction moderated the association between socioeconomic status (SES), visual-spatial processing and emerging working memory assessed at 24 months post-term among 75 toddlers born preterm or low birth weight. METHOD: SES and neonatal risk data were collected at hospital discharge and mother-child play interactions were observed at 16-month post-term. General cognitive abilities, verbal/nonverbal working memory and visual-spatial processing data were collected at 24 months. RESULTS: Neonatal risks did not moderate the associations between SES and 24-month outcomes. However, lower mother-initiated task changes were related to better 24-month visual-spatial processing among children living in higher SES homes. Mothers' flexible responses to child initiated task changes similarly moderated the impact of SES on 24-month visual-spatial processing. CONCLUSION: Our results suggest that mothers' play behaviors differentially relate to child outcomes depending on household SES.

Emerging self-regulation in toddlers born preterm or low birth weight: differential susceptibility to parenting?

The differential susceptibility to parenting model was examined in relation to toddler self-regulation in a prospective longitudinal study of infants born preterm or low birth weight. We followed 153 mother-infant dyads across five time points between the infant's Neonatal Intensive Care Unit stay and 24 months postterm. Assessments of infant temperament, quality of early parenting interactions, contextual variables, and toddler effortful control and behavior problems were conducted. Results supported differential susceptibility and dual risk models in addition to documenting main effects of early parenting on children's emerging self-regulation. Our data suggested that preterm or low birth weight infants who were prone to distress or rated by mothers as more difficult were particularly susceptible to the effects of early negative parenting.

Maternal scaffolding and preterm toddlers' visual-spatial processing and emerging working memory.

OBJECTIVE: We examined longitudinal associations among neonatal and socioeconomic risks, maternal scaffolding behaviors, and 24-month visual-spatial processing and working memory in a sample of 73 toddlers born preterm or low birthweight (PT LBW). METHODS: Risk data were collected at hospital discharge and dyadic play interactions were observed at 16-months postterm. Abbreviated IQ scores, verbal/nonverbal working memory, and verbal/nonverbal visual-spatial processing data were collected at 24-months postterm. RESULTS: Higher attention scaffolding and lower emotion scaffolding during 16-month play were associated with 24-month verbal working memory scores. A joint significance test revealed that maternal attention and emotion scaffolding during 16-month play mediated the relationship between socioeconomic risk and 24-month verbal working memory. CONCLUSIONS: These findings suggest areas for future research and intervention with children born PT LBW who also experience high socioeconomic risk.

The development of effortful control in children born preterm.

This prospective longitudinal study examined emerging effortful control skills at 24- and 36-months postterm in 172 children born preterm (<36 weeks gestation). Infant (neonatal health risks), family (sociodemographic risks), and maternal risk factors (depressive symptoms, anger expressions during play interactions) were assessed at six time points across 3 years. In addition, children's emerging effortful control skills, cognitive development, and mother-reported behavior and attention problems were assessed at 24 and 36 months. Analyses documented links between effortful control skills, cognitive skills, and concurrent attention problems in children born preterm. The study also found that preterm children's effortful control skills improved over time. In addition, neonatal health risks, family sociodemographic risks, and angry parenting interactions were associated with less optimal effortful control skills.

Attachment and caregiving relationships in families affected by parental incarceration.

This longitudinal, mixed method study focused on 57 families of children who participated in a mentoring program for children of incarcerated parents. Children ranged in age from 4 to 15 years. Monthly interviews were conducted with children, caregivers, and mentors during the first six months of program participation, and questionnaires were administered at intake and six months to assess caregiver-child and incarcerated parent-child relationships, contact with incarcerated parents, and children's behavior problems. Although some children viewed their incarcerated parents as positive attachment figures, other children reported negative feelings toward or no relationship with incarcerated parents. In addition, our assessments of children nine years old and older revealed that having no contact with the incarcerated parent was associated with children reporting more feelings of alienation toward that parent compared to children who had contact. Children's behavior problems were a primary concern, often occurring in a relational context or in reaction to social stigma associated with parental imprisonment.

An attachment perspective on incarcerated parents and their children.

The United States now incarcerates more people than any other country in the world (Pew Charitable Trust, 2008), and most of these incarcerated individuals have one or more children 18 years of age or younger (Glaze & Maruschak, 2008). Although the actual number is not known because the information is not systematically collected by jails, prisons, schools, child welfare agencies, or other organizations or institutions, a conservative estimate is that more than three million children are affected (Glaze & Maruschak, 2008; Western & Wildeman, 2009). In editing this special issue we had two major goals: (1) to introduce the many issues raised by parental incarceration to readers already grounded in attachment theory and research and (2) to highlight the importance of an attachment perspective to those who study and work with incarcerated parents. The contributors to this special issue present conceptual and empirical articles focusing on attachment issues related to incarcerated parents and their children. This introduction provides an overview of these contributions.

A transactional model of sleep-wake regulation in infants born preterm or low birthweight.

OBJECTIVE: To test a transactional model of sleep-wake development in infants born preterm or low birthweight (PT LBW), which may inform clinical practice, interventions, and future research in this at risk population. METHODS: One hundred and twenty-eight mother-infant dyads participated from hospital discharge to 4 months postterm. Assessments of prematurity, infant sleep-wake patterns, maternal interaction quality, depression, feeding route, and sociodemographic factors were conducted. RESULTS: Path analyses revealed that maternal interactions directly related to infant sleep patterns and family sociodemographic risks related to less optimal parenting. In addition, bottle fed infants experienced fewer night wakings and more nighttime sleep. CONCLUSIONS: Two potential pathways to sleep patterns in PT LBW infants were identified. The findings suggest directions for clinical work, such as supporting healthy infant sleep through parenting interventions or supporting interpersonal relations between parents and their PT LBW infants by encouraging more daytime naps. Additionally, clinicians should assess parents' nighttime sleep concerns within the larger sociodemographic and feeding context.

Incarcerated mothers' contact with children, perceived family relationships, and depressive symptoms.

Concurrent relations among contact with children, perceived family relationships, early experiences of relationship disconnection and trauma, and maternal depressive symptoms were examined in 94 incarcerated mothers with children between the ages of 2 and 7 years. Qualitative analysis revealed that most mothers experienced intense distress when initially separated from their children, although many women currently viewed the situation in a more balanced way. Quantitative findings indicated that fewer visits from children and early experiences of relationship disconnection and trauma were associated with elevated maternal depressive symptoms. Mother-child relationships were more positive when mothers had more frequent telephone contact with older children. Moreover, conflicted relationships with caregivers related to less contact between mothers and their children. Results highlight the need for mental health services for incarcerated women and suggest that interventions aimed at increasing contact between imprisoned mothers and their children should consider the quality of the mother-caregiver relationship.

Cognitive delay and behavior problems prior to school age.

OBJECTIVE: To investigate the relationship between cognitive delay (CD) and behavior problems between ages 9 months and 5 years, while adjusting for covariates related to CD. METHODS: Data were from 4 waves of the Early Childhood Longitudinal Study, Birth Cohort (n = 8000). Children were classified as typically developing (TD) or as having resolved, newly developed, or persistent CD between 9 and 24 months, based on scores from the Bayley Short Form-Research Edition below or above the 10th percentile. Child behavior was measured by using the Infant/Toddler Symptom Checklist (ages 9 and 24 months) and the Preschool and Kindergarten Behavior Scales (ages 4 and 5 years); children in the top 10th percentile were considered to have a behavior problem. Hierarchical linear modeling estimated the effect of CD status on children's behavioral trajectories, adjusted for confounders. RESULTS: CD resolved for 80.3% of children between 9 and 24 months. Behavior problems at 24 months were detected in 19.3%, 21.8%, and 35.5% of children with resolved, newly developed, and persistent CD, respectively, versus 13.0% of TD children. Behavior problems increased among children with CD over time, and more so among children with persistent CD. By age 5, children with persistent CD had behavior scores moderately (0.59 SD) higher than TD children. CONCLUSIONS: Behavior problems among children with CD are slightly higher at 9 months, clearly evident by 24 months, and increase as children move toward school age. Efforts to promote the earliest identification, evaluation, and service referral may be necessary to improve outcomes for these children.

Effortful control, positive emotional expression, and behavior problems in children born preterm.

The present study focused on the role of high effortful control in the expression of positive emotion and development of behavior problems in children born preterm (mean gestational age = 31.4 weeks). Using data from a prospective longitudinal study, the present study assessed effortful control and behavior problems at 24 and 36 months and positive emotional expression at 24 months in a sample of 173 children born preterm. Less positive emotional expression was associated with higher effortful control for boys but not girls. Higher effortful control was associated with fewer total behavior problems, but this relation was attenuated when socioeconomic assets were included in the model. More socioeconomic assets were associated with fewer behavior problems for both boys and girls and higher effortful control for girls. Socioeconomic assets appear to be an important factor in the development of effortful control and behavior problems in children born preterm regardless of gender, whereas positive emotional expression was important for boys. Future intervention research should examine fostering adaptive levels of effortful control in high-risk populations as a means to facilitate resilience processes.

Predictors of parenting stress trajectories in premature infant-mother dyads.

This prospective longitudinal study examined predictors of parenting stress trajectories over time in a sample of 125 mothers and their preterm infants. Infant (multiple birth, gestational age, days hospitalized, and neonatal health risks) and maternal (socioeconomic, education, depressive symptoms, social support, and quality of interaction during infant feeding) characteristics were collected just prior to infant hospital discharge. Parenting stress and maternal interaction quality during play were measured at 4, 24, and 36 months corrected age. Hierarchical linear modeling was used to analyze infant and maternal characteristics as predictors of parenting stress scores and change over time. Results indicated significant variability across individuals in parenting stress at 4 months and in change trajectories. Mothers of multiples and infants with more medical risks and shorter hospitalization, and mothers with lower education and more depressive symptoms, reported more parenting stress at 4 months of age. Parenting stress decreased over time for mothers of multiples and for mothers with lower education more than for mothers of singletons or for mothers with higher educational levels. Changes in parenting stress scores over time were negatively associated with maternal behaviors during mother-infant interactions. Results are interpreted for their implications for preventive interventions.

The paradox of prematurity: the behavioral vulnerability of late preterm infants and the cognitive susceptibility of very preterm infants at 36 months post-term.

We explored associations among preterm status (very preterm infant (VPI: <30 weeks), moderate preterm (MPI: 30-33(6/7) weeks), late preterm (LPI: 34-36(6/7) weeks), parenting, and 3-year cognitive and behavioral outcomes. We hypothesized that LPIs would demonstrate better health and neurobehavioral outcomes compared with more premature infants, and that preterm status would moderate the association between parenting quality and 3-year outcomes. Sample included 123 preterm infants (gestation <37 weeks) and their mothers from a larger study of high-risk infants with measures of neonatal and socioeconomic risks at hospital discharge; maternal vocabulary at 9-months, child IQ and behavior at 36 months, and maternal depressive symptoms and parenting at all timepoints. Group differences were explored using MANOVAs while predictors of child outcomes were explored using hierarchical regression analyses. MANOVAs indicated that LPIs had more optimal neonatal health during the hospital stay, yet more externalizing (p=.043), aggressive (p=.006) and oppositional behaviors (p=.008) at 3 years compared with VPIs. There were no IQ differences between VPIs, MPIs and LPIs. However, preterm infants who experienced less negative parenting had higher IQs at 36 months (ß=-3.245, p=.017), with the greatest effects seen in VPIs (ß=0.406, p=.01) compared with LPIs (ß=0.148, p=.381). LPIs manifested similar IQ, but more externalizing, oppositional and aggressive behavior symptoms compared to VPIs. VPIs appeared to be differentially susceptible to parenting effects, with VPIs demonstrating the highest cognitive scores in the context of more positive parenting.

Parent-child interaction, maternal depressive symptoms and preterm infant cognitive function.

Preterm infants are at risk for cognitive difficulties due to infant neurological immaturity and family social disadvantage, and this may be exacerbated by maternal depressive symptoms. This longitudinal study of infants born preterm (<35 weeks) or low birth weight (<2500 g) (n = 137) tests if maternal depressive symptoms at 4 months is associated with preterm children's cognitive function at 16 months. Additionally, we test if this association is mediated by the quality of parent-child interaction at 9 months, and if these associations differ by levels of maternal social support. Children's cognitive function was measured using the Bayley Scales of Infant Development, 2nd edition. Maternal depressive symptoms were measured using the Center for Epidemiologic Studies Depression Scale. Perceived social support was measured using the Maternal Support scale. The quality of parent-child interaction was measured using the Parent-Child Early Relational Assessment. Linear regression and structural equation modeling were used to test the research questions. Postnatal depression at 4 months is associated with lower cognitive function (mean difference = -5.22, 95% CI: [-10.19, -0.25]) at 16 months controlling for a host of socioeconomic characteristics. For mothers with fewer depressive symptoms, bolstering effects of maternal supports on children's cognitive function were evident. We find no evidence for effect mediation by quality of parent-child interaction. Early exposure to maternal depressive symptoms appears to have a negative influence on preterm children's later cognitive function. These findings suggest important policy and programmatic implications for early detection and intervention for families of preterm infants.
