Relation of perinatal risk and early parenting to executive control at the transition to school

"My Brigham Baby" Application: A Pilot Study Using Technology to Enhance Parent's Experience in the Neonatal Intensive Care Unit

OBJECTIVE

 This study aimed to describe the family psychosocial experience in a level-III neonatal intensive care unit (NICU), and to assess how it evolved after rollout of an educational smartphone application (App) called "My Brigham Baby."

STUDY DESIGN

 We surveyed 25 NICU parents pre-App rollout (before coronavirus disease 2019 [COVID-19] pandemic) and 25 parents post-App rollout (during pandemic). Collected data included parental self-reported discharge readiness, symptoms of stress and anxiety, and parenting skill confidence. Survey scores were assessed as total or mean scores, and by category of severity.

RESULTS

 Pre-and post-App parents had comparable demographics, and their infants had similar clinical characteristics during their NICU stay. Discharge readiness differed by group status (p = 0.02) and was characterized by a greater frequency in being "very ready" for discharge among the post-App rollout parent group compared with the pre-App group (56 vs. 20%, p = 0.027), and parenting confidence shifted toward more optimal scores post-App rollout. Parental stress and anxiety symptoms did not significantly differ between groups despite possible stress contagion from the COVID-19 pandemic.

CONCLUSION

 This pilot study suggests that technology Apps are feasible interventions within NICU settings and may enhance parental experiences related to NICU hospitalization.

KEY POINTS

· Parents' experience increased psychological distress during the time their infant is cared for in the NICU, which has downstream consequences for the family unit.. · In our study, surveyed parents reported higher discharge readiness and parenting confidence shifted toward improvement after rollout of a family education and support smartphone application in a level-III NICU.. · This pilot study suggests that technology applications are feasible interventions that might enhance parental experiences during NICU hospitalization..

Parenting Influences on Frontal Lobe Gray Matter and Preterm Toddlers' Problem-Solving Skills

Children born preterm often face challenges with self-regulation during toddlerhood. This study examined the relationship between prematurity, supportive parent behaviors, frontal lobe gray matter volume (GMV), and emotion regulation (ER) among toddlers during a parent-assisted, increasingly complex problem-solving task, validated for this age range. Data were collected from preterm toddlers (n = 57) ages 15-30 months corrected for prematurity and their primary caregivers. MRI data were collected during toddlers' natural sleep. The sample contained three gestational groups: 22-27 weeks (extremely preterm; EPT), 28-33 weeks (very preterm; VPT), and 34-36 weeks (late preterm; LPT). Older toddlers became more compliant as the Tool Task increased in difficulty, but this pattern varied by gestational group. Engagement was highest for LPT toddlers, for older toddlers, and for the easiest task condition. Parents did not differentiate their support depending on task difficulty or their child's age or gestational group. Older children had greater frontal lobe GMV, and for EPT toddlers only, more parent support was related to larger right frontal lobe GMV. We found that parent support had the greatest impact on high birth risk (≤27 gestational weeks) toddler brain development, thus early parent interventions may normalize preterm child neurodevelopment and have lasting impacts.

Socioeconomic disadvantage and parental mood/affective problems links negative parenting and executive dysfunction in children born very preterm

Poverty increases the risk of poorer executive function (EF) in children born full-term (FT). Stressors associated with poverty, including variability in parenting behavior, may explain links between poverty and poorer EF, but this remains unclear for children born very preterm (VPT). We examine socioeconomic and parental psychosocial adversity on parenting behavior, and whether these factors independently or jointly influence EF in children born VPT. At age five years, 154 children (VPT = 88, FT = 66) completed parent-child interaction and EF tasks. Parental sensitivity, intrusiveness, cognitive stimulation, and positive and negative regard were coded with the Parent-Child Interaction Rating Scale. Socioeconomic adversity spanned maternal demographic stressors, Income-to-Needs ratio, and Area Deprivation Index. Parents completed measures of depression, anxiety, inattention/hyperactivity, parenting stress, and social-communication interaction (SCI) problems. Parental SCI problems were associated with parenting behavior in parents of children born VPT, whereas socioeconomic adversity was significant in parents of FT children. Negative parenting behaviors, but not positive parenting behaviors, were related to child EF. This association was explained by parental depression/anxiety symptoms and socioeconomic adversity. Results persisted after adjustment for parent and child IQ. Findings may inform research on dyadic interventions that embed treatment for parental mood/affective symptoms and SCI problems to improve childhood EF.

Non-Intrusive Maternal Style as a Mediator between Playfulness and Children’s Development for Low-Income Chilean Adolescent Mothers

The aim of this study was to describe the relationship between low-income Chilean adolescent maternal playfulness and mothers’ non-intrusiveness in their children’s development and to analyze whether a mother’s non-intrusiveness mediates the relationship between maternal playfulness and children’s development. The Parental Playfulness Scale and the Subscale of Intrusiveness from the Early Head Start Research and Evaluation Project were used to assess maternal playfulness and mothers’ non-intrusiveness respectively. Ages and Stages Questionnaire 3rd Edition (ASQ-3) was applied to measure the children’s communication, gross and fine motor skills, problem-solving and personal–social development. The sample consisted of 79 mother–child dyads with children aged 10–24 months (M = 15.5, SD = 4.2) and their mothers aged 15–21 years old (M = 19.1, SD = 1.7). A bivariate analysis showed that maternal playfulness was significantly associated with communication, fine motor, problem-solving and personal–social development. Moreover, higher levels of communication, fine motor skills and problem-solving development were observed in the children of less intrusive mothers. Maternal playfulness had a significant effect on children’s development of language, problem-solving and personal–social skills when their mothers showed less intrusiveness during interaction. These findings contribute to the understanding of the interaction between adolescent mothers and their children. Active play and less intrusiveness can enhance child development.

Mathematical skills of 11-year-old children born very preterm and full-term

Preterm birth affects the academic development of children, especially in mathematics. Remarkably, only a few studies have measured specific effects of preterm birth on mathematical skills in primary school. The aim of this study was to compare 11-year-old children, with an IQ above 70, born very preterm (N = 64) and full-term (N = 72) on a variety of 5th grade mathematical skills and cognitive abilities important for mathematical learning. The measures were spontaneous focusing on numerosity (SFON), spontaneous focusing on quantitative relations (SFOR), arithmetic fluency, mathematics achievement, number line estimation, rational number magnitude knowledge, mathematics motivation, reading skills, visuospatial processing, executive functions, and naming speed. The children born very preterm and full-term differed in arithmetic fluency, SFON and SFOR. Domain general cognitive abilities did not fully explain the group differences in SFON and SFOR. Retrospective comparisons of the samples at the age of five years showed large group differences in early mathematical skills and cognitive abilities. Despite lower early mathematical skills, the children born very preterm reached peer equivalent performance in many mathematical skills by the age of 11 years. Nevertheless, they appear less likely to focus on implicit mathematical features in their everyday life.

Parenting and Neurobehavioral Outcomes in Children Born Moderate-to-Late Preterm and at Term

OBJECTIVES

To compare the parenting environment and the relationships between parenting behaviors and concurrent child neurobehavioral outcomes at 2 years of corrected age between children born moderate-to-late preterm (MLP; 32-36 weeks of gestation) and at term (≥37 weeks of gestation).

STUDY DESIGN

Participants were 129 children born MLP and 110 children born at term and their mothers. Mothers' parenting behaviors (sensitivity, structuring, nonintrusiveness, nonhostility) were assessed at 2 years of corrected age using the Emotional Availability Scales. Child cognitive and language development were assessed using the Bayley Scales of Infant and Toddler Development, and social-emotional competence using the Infant Toddler Social and Emotional Assessment.

RESULTS

Mothers of children born MLP and at term displayed similar parenting behaviors overall, with slightly lower nonintrusiveness in mothers of children born MLP (adjusted mean difference -0.32 [-0.60, -0.04]; P = .03). In both groups of children, greater maternal sensitivity was associated with better cognitive development (P < .001 MLP; P = .02 term), increased maternal structuring was associated with better social-emotional competence (P = .02 MLP; P = .03 term), and higher maternal nonintrusiveness was associated with better cognitive, language, and social-emotional outcomes (all P < .04). Greater maternal sensitivity and structuring were associated with better language development in children born MLP but not in children born at term.

CONCLUSIONS

Parenting behaviors are important for neurobehavioral outcomes in children born MLP and at term. Language development may be more strongly influenced by select parenting behaviors in children born MLP compared with children born at term.

Mental health, neurodevelopmental, and family psychosocial profiles of children born very preterm at risk of an early-onset anxiety disorder

AIM

To compare the mental health and neurodevelopmental profiles of school-age children born very preterm, with and without an anxiety disorder, and to identify neonatal medical, psychosocial, and concurrent neurodevelopmental correlates.

METHOD

A regional cohort of 102 (51 males, 51 females) children born very preterm (mean [SD] gestation at birth=28wks [2], range=23-31wks) was studied from birth to age 9 years alongside a comparison group of 109 (58 males, 51 females) children born at term (mean [SD] gestation at birth=40wks [1], range=38-41wks). At age 9 years, all children underwent a neurodevelopmental evaluation while parents were interviewed using the Development and Well-Being Assessment to diagnose a range of DSM-IV childhood psychiatric disorders. Detailed information was also available about the children's neonatal medical course and postnatal psychosocial environment, including maternal mental health and parenting.

RESULTS

At age 9 years, 21% (n=21) of very preterm and 13% (n=14) of term-born children met diagnostic criteria for an anxiety disorder. Clinically-anxious children born very preterm were characterized by higher rates of comorbid mental health (odds ratio [OR]=11.5, 95% confidence interval [CI]=3.8-34.7), social (OR=6.2, 95% CI=2.1-18.4), motor (OR=4.4, 95% CI=1.6-12.2), and cognitive (OR=2.6, 95% CI=1.0-7.0) problems than those without an anxiety disorder. Concurrent maternal mental health and child social difficulties were the strongest independent correlates of early-onset child anxiety disorders.

INTERPRETATION

Children born very preterm who developed an early-onset anxiety disorder were subject to high rates of comorbid problems. Findings highlight the importance of addressing both maternal and child mental health issues to optimize outcomes in this high-risk population. What this paper adds One out of five school-age children born very preterm are likely to meet DSM-IV diagnostic criteria for an anxiety disorder. Half of these children born very preterm with an early-onset anxiety disorder have comorbid attention-deficit/hyperactivity disorder. Other neurodevelopmental correlates of early-onset anxiety disorders include lower cognitive ability, motor problems, and peer social difficulties. Concurrent maternal mental health and child social adjustment problems were the strongest correlates of early-onset anxiety disorder risk among children born very preterm.

The impact of preterm birth on the executive functioning of preschool children: A systematic review

This paper presents a systematic review of the impact of preterm childbirth on the later executive functioning of preschool-aged children. A systematic search for studies published between 2014 and 2019 was performed using the following keywords: executive funct* AND preterm AND child. The methodological quality of the reports was examined using the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement. Thirty-two studies were reviewed and scored at least 67% on the methodological quality assessment. In comparison to children born full-term, preschool children born preterm exhibit executive functioning deficits in the dimensions of the global index, inhibitory control, cognitive flexibility, working memory, and planning/executive functioning. These findings are independent of the degree of prematurity at birth. Since executive functioning has many complex components, future studies should assess the dimensions of executive functioning separately in preschool-aged children born preterm, rather than as a single measure.

Controlling Parenting Behaviors in Parents of Children Born Preterm: A Meta-Analysis

OBJECTIVE

This meta-analysis tested whether parents of preterm-born children differ from parents of full-term-born children regarding controlling parenting.

METHODS

Databases of PubMed, Scopus, Web of Science, Open Access Theses and Dissertations, and Elton B. Stephens Company were searched for cross-sectional and prospective longitudinal studies examining controlling parenting in preterm-born children.

RESULTS

The meta-analysis included 27 independent data sets, derived from 34 studies, with a total of 8053 participants-3265 preterm and 4788 full-term children. Parents of children born preterm were more controlling than parents of children born full-term (Hedges' g = 0.29; 95% confidence interval: 0.19-0.39; z = 5.48; p < 0.001). Heterogeneity analysis indicated significant variation in effects between studies (Q = 148.46, p < 0.001), but the effects were not moderated by gestational age, birth weight, child age, child gender, parental education, type of parenting assessment method (observational vs parental self-report), parenting dimension measured (behaviors vs attitudes), type of controlling parenting (intrusiveness vs others), study design (cross-sectional vs longitudinal), year of publication, or geographical setting of the studies (America vs Europe).

CONCLUSION

Findings suggest that parents of children born preterm are at higher risk for engaging in controlling parenting strategies, stressing the importance of psychosocial follow-up support for these parents.

Parenting and Children's Executive Function Stability Across the Transition to School

When children transition to school between the ages of 4 and 6 years, they must learn to control their attention and behavior to be successful. Concurrently, executive function (EF) is an important skill undergoing significant development in childhood. To understand changes occurring during this period, we examined the role of parenting in the development of children's EF from 4 to 6 years old. Participants were mother and child dyads (N = 151). Children completed cognitive tasks to assess overall EF at age 4 and age 6. At both time points, mothers and children completed interaction tasks which were videotaped and coded to assess various parenting dimensions. Results indicated that children with high EF at age 4 were more likely to have high EF at age 6. In addition, results suggested that higher levels of positive parenting across the transition to school promote stability of individual differences in EF.

Does early maternal responsiveness buffer prenatal tobacco exposure effects on young children's behavioral disinhibition?

Children with prenatal tobacco exposure (PTE) exhibit early self-regulatory impairments, reflecting a life-course persistent propensity toward behavioral disinhibition. Previously, we demonstrated the protective role of parental responsiveness for reducing the risk of exposure-related disruptive behavior in adolescence. Here, we expanded this line of inquiry, examining whether responsiveness moderates the relation of PTE to a broader set of behavioral disinhibition features in early childhood and testing alternative diathesis-stress versus differential susceptibility explanatory models. PTE was assessed prospectively using interviews and bioassays in the Midwestern Infant Development Study (MIDS). Mother-child dyads (N = 276) were re-assessed at approximately 5 years of age in a preschool follow-up. We quantified maternal responsiveness and child behavioral disinhibition using a combination of directly observed activities in the lab and developmentally sensitive questionnaires. Results supported a diathesis-stress pattern. Children with PTE and less responsive mothers showed increased disruptive behavior and lower effortful control compared with children without PTE. In contrast, exposed children with more responsive mothers had self-regulatory profiles similar to their non-exposed peers. We did not observe sex differences. Findings provide greater specification of the protective role of maternal responsiveness for self-regulation in children with PTE and help clarify mechanisms that may underscore trajectories of exposure-related behavioral disinhibition.

Educating parents to improve parent-child interactions: Fostering the development of attentional control and executive functioning

Background

Parent–child interaction is essential in the development of attentional control (AC) and executive functioning (EF). Educating parents in AC and EF development may help them to respond more adaptively to their child's developmental needs.

Aim

This study aimed to investigate whether parents can be educated to improve interactions with their child through a compact psycho‐educational programme that focuses on fostering the development of AC and EF.

Sample

Parents and their children in a low‐risk sample of four‐ to eight‐year‐olds were randomly assigned to either the educational programme condition (N = 34) or the control condition (N = 36).

Methods

Parental supportive presence and intrusiveness were observed during home visits, and children's performance‐based AC and EF were assessed before and after the four‐session programme.

Result

Parents in the educational programme improved significantly in support (ηp2 = .19) and intrusiveness (ηp2 = .09) compared to controls. There was no short‐term programme mediation effect on child AC and EF through parental support and intrusiveness. This study showed, however, that parents who improved after the educational programme had children who improved on AC and EF.

Conclusion

Parent–child interaction can be enhanced in a low‐risk sample of four‐ to eight‐year‐olds using a compact educational group programme within the school community. Future studies should aim at examining variations in programme responsiveness and assessing associations between parent–child interaction and AC and EF over time.

Associations between parenting behavior and executive function among preschool-aged children born very preterm

The objective of the current study was to determine whether three domains of observed parenting behavior were associated with executive function in preschool-aged children born very preterm (<30 completed weeks' gestation). Executive function of 41 preschool-aged (3.5 to 4.5 years) children was assessed using a standardized protocol (gift delay) and by parent-report (Behavior Rating Inventory of Executive Function-Preschool, BRIEF-P). Observational protocols were used to determine parental sensitivity, harsh intrusiveness, and dyadic mutuality in a semi-structured play task. Parental sensitivity and mutuality were rated as higher, and harsh intrusiveness was rated as lower for children high in executive function on the gift delay task. Similarly, correlations between the three parenting scales and the BRIEF-P Global Executive Composite t-score were in the expected direction though not always statistically significant. Findings suggest that very preterm children who experienced sensitive parenting and were rated as having greater mutuality in their interactions with their caregivers scored higher on executive function tasks. These findings add to the growing literature on the key role that sensitive parenting and mutually responsive, harmonious interactions between caregivers and children may play in the development of executive function in very preterm children.

Resilience in Extremely Preterm/Extremely Low Birth Weight Kindergarten Children

OBJECTIVES

Research on developmental outcomes of preterm birth has traditionally focused on adverse effects. This study investigated the prevalence and correlates of resilience in 146 extremely preterm/extremely low birth weight (EPT/ELBW) children (gestational age &lt;28 weeks and/or birth weight &lt;1000 g) attending kindergarten and 111 term-born normal birth weight (NBW) controls.

METHODS

Adaptive competence (i.e., "resilience" in the EPT/ELBW group) was defined by scores within grade expectations on achievement tests and the absence of clinically elevated parent ratings of child behavior problems. The "adaptive" children who met these criteria were compared to the "maladaptive" children who did not on child and family characteristics. Additional analyses were conducted to assess the conjoint effects of group (ELBW vs. NBW) and family factors on adaptive competence.

RESULTS

A substantial minority of the EPT/ELBW group (45%) were competent compared to a majority of NBW controls (73%), odds ratio (95% confidence interval)=0.26 (0.15, 0.45), p&lt;.001. Adaptive competence was associated with higher cognitive skills, more favorable ratings of behavior and learning not used to define adaptive competence, and more advantaged family environments in both groups, as well as with a lower rate of earlier neurodevelopmental impairment in the EPT/ELBW group. Higher socioeconomic status and more favorable proximal home environments were associated with competence independent of group, and group differences in competence persisted across the next two school years.

CONCLUSIONS

The findings document resilience in kindergarten children with extreme prematurity and highlight the role of environmental factors as potential influences on outcome. (JINS, 2019, 25, 362-374).

Socioeconomic status and early blood concentrations of inflammation-related and neurotrophic proteins among extremely preterm newborns

The main objective of this study was to evaluate the relationship between mother’s socioeconomic disadvantage and blood concentrations of inflammation-related proteins among extremely preterm newborns (<28 weeks gestation), a group at heightened risk of cognitive impairment when exposed to systemic inflammation. We measured the concentrations of 27 inflammatory and neurotrophic proteins in blood specimens collected a week apart during the first postnatal month from 857 extremely preterm newborns in the United States. We classified children according to 3 indicators/correlates of socioeconomic disadvantage, mother’s eligibility for government-provided medical care insurance (Medicaid), mother’s formal education level, and mother’s IQ approximated with the Kaufman Brief Intelligence Test– 2. The risks of a top-quartile concentration of each protein on each of 5 days a week apart, on two occasions during the first two postnatal weeks, and during the next two weeks were modeled as functions of each indicator of socioeconomic disadvantage. The risks of top quartile concentrations of multiple (2–5) inflammation-related proteins on multiple days during the first two weeks were increased for each of the 3 indicators of socioeconomic disadvantage, while the risks of top quartile concentrations of selected neurotrophic proteins were reduced. Adjustment for socioeconomic disadvantage did not alter the relationships between protein concentrations and both low IQ and low working memory 10 years later. Among extremely preterm newborns, indicators of socioeconomic disadvantage are associated with modestly increased risk of systemic inflammation in postnatal blood during the first postnatal month and with a slightly reduced risk of a neurotrophic signal, but do not confound relationships between protein concentrations and outcomes.

Academic performance of children born preterm: a meta-analysis and meta-regression

BACKGROUND

Advances in neonatal healthcare have resulted in decreased mortality after preterm birth but have not led to parallel decreases in morbidity. Academic performance provides insight in the outcomes and specific difficulties and needs of preterm children.

OBJECTIVE

To study academic performance in preterm children born in the antenatal steroids and surfactant era and possible moderating effects of perinatal and demographic factors.

DESIGN

PubMed, Web of Science and PsycINFO were searched for peer-reviewed articles. Cohort studies with a full-term control group reporting standardised academic performance scores of preterm children (<37 weeks of gestation) at age 5 years or older and born in the antenatal steroids and surfactant era were included. Academic test scores and special educational needs of preterm and full-term children were analysed using random effects meta-analysis. Random effects meta-regressions were performed to explore the predictive role of perinatal and demographic factors for between-study variance in effect sizes.

RESULTS

The 17 eligible studies included 2390 preterm children and 1549 controls. Preterm children scored 0.71 SD below full-term peers on arithmetic (p<0.001), 0.44 and 0.52 SD lower on reading and spelling (p<0.001) and were 2.85 times more likely to receive special educational assistance (95% CI 2.12 to 3.84, p<0.001). Bronchopulmonarydysplasia explained 44% of the variance in academic performance (p=0.006).

CONCLUSION

Preterm children born in the antenatal steroids and surfactant era show considerable academic difficulties. Preterm children with bronchopulmonarydysplasia are at particular risk for poor academic outcome.

Cognitive outcomes in children and adolescents born very preterm: a meta-analysis

AIM

To estimate the association between very preterm birth (<32wks' gestation) and intelligence, executive functioning, and processing speed throughout childhood and adolescence, and to examine the effects of gestational age, birthweight, and age at assessment.

METHOD

Studies were included if children were born at earlier than 32 weeks' gestation, aged 4 to 17 years, had an age-matched term control group, and if the studies used standardized measures, were published in an English-language peer-reviewed journal, and placed no restrictions on participants based on task performance.

RESULTS

We evaluated 6163 children born very preterm and 5471 term-born controls from 60 studies. Children born very preterm scored 0.82 SDs (95% confidence interval [CI] 0.74-0.90; p<0.001) lower on intelligence tests, 0.51 SDs (95% CI 0.44-0.58; p<0.001) lower on measures of executive functioning, and 0.49 SDs (95% CI 0.39-0.60; p<0.001) lower on measures of processing speed than term-born controls. Gestational age and birthweight were associated with study effect size in intelligence and executive functioning of younger children only. Age at assessment was not associated with study effect size.

INTERPRETATION

Children born very preterm have medium to large deficits in these cognitive domains.

WHAT THIS PAPER ADDS

This meta-analysis is centred on very preterm birth and three cognitive domains. The three critical cognitive domains are intelligence, executive functioning, and processing speed.

Antenatal and Neonatal Antecedents of Executive Dysfunctions in Extremely Preterm Children

To find out why children born extremely preterm are at heightened risk of executive dysfunctions, the authors assessed 716 children who were 10 years old born extremely preterm whose IQ was ≥ 70. A working memory dysfunction (n = 169), an inhibition dysfunction (n = 360), a switching dysfunction (355), and all 3 (executive dysfunction; n = 107) were defined on the basis of Z-scores ≤ -1 on the Differential Ability Scales-II Working Memory composite, and/or on the NEPSY-II Inhibition-Inhibition and Inhibition-Switching subtests. All risk profiles include an indicator of socioeconomic disadvantage. The risk profile of each of the 3 individual dysfunctions includes an indicator of the newborn's immaturity, and the risk profiles of the inhibition dysfunction and switching dysfunction also include an indicator of inflammation. Only the switching dysfunction was associated with fetal growth restriction. The risk factors for executive dysfunction can be subsumed under the 4 themes of socioeconomic disadvantage, immaturity/vulnerability, inflammation, and fetal growth restriction.

Executive function in children born preterm: Risk factors and implications for outcome

Executive function (EF) refers to the set of cognitive processes involved in the self-regulation of emotion and goal-directed behavior. These skills and the brain systems that support them develop throughout childhood and are frequently compromised in preterm children, even in those with broadly average global cognitive ability. Risks for deficits in EF in preterm children and attendant problems in learning and psychosocial functioning are higher in those with more extreme prematurity, neonatal complications, and related brain abnormalities. Associations of higher levels of EF with more supportive home and school environments suggest a potential for attenuating these risks, especially with early identification. Further research is needed to understand how deficits in EF evolve in preterm children, refine assessment methods, and develop interventions that either promote the development of EF in this population or help children to compensate for these weaknesses.

Processing speed, executive function, and academic achievement in children with dextro-transposition of the great arteries: Testing a longitudinal developmental cascade model

OBJECTIVE

To establish executive function (EF) structure/organization and test a longitudinal developmental cascade model linking processing speed (PS) and EF skills at 8-years of age to academic achievement outcomes, both at 8- and 16-years, in a large sample of children/adolescents with surgically repaired dextro-transposition of the great arteries (d-TGA).

METHOD

Data for this study come from the 8- (n = 155) and 16-year (n = 139) time points of the Boston Circulatory Arrest Study and included WISC-III, Trail Making Test, Test of Variables of Attention, and WIAT/WIAT-II tasks.

RESULTS

A 2-factor model (Working Memory/Inhibition and Shifting) provided the best fit for the EF data, χ²(3) = 1.581, p = .66, RMSEA = 0, CFI = 1, NNFI = 1.044). Working Memory/Inhibition and Shifting factors were not correlated. In the structural equation model, PS was directly related to both EF factors and Reading at 8 years, and was indirectly related to Math and Reading achievement, both concurrently and longitudinally, via its effects on Working Memory/Inhibition. Shifting at 8 years was significantly associated with Math (but not Reading) at 16 years.

CONCLUSIONS

The academic difficulties experienced by children and adolescents with d-TGA may be driven, at least in part, by underlying deficits in processing speed and aspects of executive function. Intervention efforts aimed at bolstering these abilities, particularly if implemented early in development, may prove beneficial in improving academic outcomes and, perhaps by extension, in reducing the stress and diminished self-confidence often associated with academic underachievement.
