During vocabulary instruction, it is important to teach words until their representations are robust enough to be retained. For adults, the number of training sessions a target item is successfully retrieved during training predicts the likelihood of post-training retention. To assess this relationship in children, we reanalyzed data from Gordon et al. (2021b, 2022). Four- to six-year-old children completed six training days with word form-object pairs and were tested one month later. Results indicate that the number of training sessions that a word form was retrieved was positively related to post-training retention. We discuss implications for vocabulary instruction and interventions.
The aim of this review is to highlight the key issues in relation to food insecurity among children and young people living in Scotland. It provides an overview of the current context of food insecurity more generally within the UK and specifically in Scotland. Food insecurity has risen in Scotland evidenced through responses to national surveys and the dramatic increase in households relying on emergency food provision. Food insecurity is highest among young people, single parent families and single men. The key drivers of food insecurity include insufficient income, welfare reform, food inflation and geo-political events. Evidence suggests that food insecurity is negatively related to sufficient nutritional intake, and the implications for physical and mental health are profound. Policy actions implemented to mitigate the impact of food insecurity on children and young people include the introduction of the Scottish Child Payment, food voucher schemes, free school meals, and holiday food provision. Further evidence is required to evaluate the success of these policies in reducing or mitigating food insecurity. The review concludes by considering the ways in which a rights-based approach to food might benefit children and young people living in Scotland, and argues that wider systemic change is required.
To develop and internally validate a Free Sugars Screener (FSS) for Australian children aged 2 and 5 years.
Design:
Using data collected from a ninety-nine-item (2-year-olds) and ninety-eight-item (5-year-olds) FFQ in the Study of Mothers’ and Infants’ Life Events affecting oral health (SMILE-FFQ), a regression-based prediction modelling approach was employed to identify a subset of items that accurately estimate total free sugars intake (FSI). The predictors were grams of free sugars (FSg) for individual items in the SMILE-FFQ and child’s age and sex. The outcome variable was total FSI per person. To internally validate the SMILE-FSS items, the estimated FSg was converted to percent energy from free sugars (%EFS) for comparison to the WHO free sugars guideline categories (< 5 %, 5–< 10 % and ≥ 10 %EFS) using cross-classification analysis.
Setting:
Australia.
Participants:
858 and 652 2- and 5-year-old children, respectively, with complete dietary (< 5 % missing) and sociodemographic data.
Results:
Twenty-two and twenty-six items were important in predicting FSI at 2 and 5 years, respectively. Items were similar between ages with more discretionary beverage items (e.g. sugar-sweetened beverages) at 5 years. %EFS was overestimated by 4·4 % and 2·6 %. Most children (75 % and 82 %) were categorised into the same WHO free sugars category with most (87 % and 95 %) correctly identified as having < 10 %EFS in line with the WHO recommendation.
Conclusions:
The SMILE-FSS has good internal validity and can be used in research and practice to estimate young Australian children’s FSI and compare to the WHO free sugars guidelines to identify those ‘at risk’.
To evaluate the impact of a menu box delivery service tailored to the long-day care (LDC) setting on improving menu compliance with recommendations, children’s diet quality and dietary intake while in care.
Design:
A cluster randomised controlled trial in LDC centres randomly assigned to an intervention (menu box delivery) or comparison (menu planning training) group. The primary outcome was child food provision and dietary intake. Secondary outcomes include menu compliance and process evaluation, including acceptability, fidelity and menu cost (per child, per day).
Setting:
South Australian LDC centres.
Participants:
Eight LDC centres (n 224 children) provided data.
Results:
No differences were observed in serves/d between intervention and comparison centres, for provision (intervention, 0·9 inter-quartile range (IQR) 0·7–1·2; comparison, 0·8 IQR 0·5–1·3) or consumption (intervention, 0·5 IQR 0·2–0·8; comparison, 0·5 IQR 0·3–0·9) of vegetables. Child food provision and dietary intake were similar across both groups for all food groups (P < 0·05). At follow-up, all intervention centres met menu planning guidelines for vegetables, whereas only one comparison centre met guidelines. Intervention centre directors found the menu box delivery more acceptable than cooks. Cost of the intervention was AUD$2·34 greater than comparison centres (intervention, AUD$4·62 (95 % CI ($4·58, $4·67)); comparison, AUD$2·28 (95 % CI ($2·27, $2·30)) per child, per day).
Conclusions:
Menu compliance can be improved via a menu delivery service, delivering equivalent impacts on child food provision and dietary intake compared with an online training programme. Further exploration of cooks acceptability and cost is essential before scaling up to implementation.
To conduct a systematic review of obesity prevention interventions in Latinx children ages birth to 6 years published in any language from 2010–2020.
Design:
We used PubMed, ERIC, PsycINFO, Scopus, Scientific Electronic Library Online (SciELO) and Google Scholar databases to conduct a search on May 1 2020, January 1 2021 and November 1 2022. We included randomised controlled trials, quasi-experimental studies and non-randomised interventions with a control or comparison group that reported measures of adiposity.
Setting:
Interventions taking place in the United States, Latin America or the Caribbean.
Participants:
Latinx children ages birth to 6 years.
Results:
Of 8601 unique records identified, forty manuscripts about thirty-nine unique studies describing thirty distinct interventions in the United States and nine interventions in Latin America and the Caribbean met our inclusion criteria. Interventions were primarily based in early care and education centres (n 13) or combined home settings, for example home and community (n 7). Randomised interventions taking place in community or home settings were more likely to report significant reductions in adiposity or weight-related outcomes compared to other settings. Using the Cochrane risk of bias tools for randomised and non-randomised studies, we judged thirty-eight randomised trials and nine non-randomised interventions to have a high or unclear risk of bias.
Conclusions:
The results highlight a need for more rigorous designs and more effective intervention strategies in Latinx children at risk for having overweight and obesity. Registered with the PROSPERO database for systematic reviews under registration number CRD42020161339.
This pilot study provides preliminary insights into whether Latino preschool children living in an emerging Latino community (ELC) are meeting recommendations for healthy diet and activity behaviours and whether those behaviours are associated with sociodemographic or home environment variables. Secondary data analysis was conducted utilising cross-sectional baseline survey data from ANDALE Pittsburgh, a home-based intervention study. Measures included parent-reported information on child dietary intake, screen time and the home environment, and objectively measured physical activity and anthropometry. χ2 and Fischer's exact tests were used to determine associations. The study was conducted in an ELC in western Pennsylvania in the US. Fifty-one Latina mothers (age: 33⋅5 ± 6⋅1 years; 63 % Mexican origin; 86 % low acculturation) and their children (age: 3⋅9 ± 1⋅3 years; 55 % male) 2–5 years of age. On average, children consumed 2⋅25 ± 1⋅44 cups of fruits/vegetables, viewed 98⋅7 ± 74⋅2 min of screen time, accumulated 12⋅9 ± 2⋅9 min/h of total physical activity and consumed 15⋅5 ± 26⋅0 kcals of sugar-sweetened beverages per day. Forty-one percent met the fruit/vegetable recommendation, 54 % met the screen time recommendation, 27 % met the physical activity recommendation and 58 % met the sugary drink recommendation. Country of origin (P = 0⋅032) and acculturation (P = 0⋅048) were significantly associated with children meeting sugary drink recommendations. No other relationships were significant. The proportion of children in this sample meeting diet and activity recommendations was mixed. More research with larger sample sizes is needed in ELCs to identify effective intervention strategies for improving health behaviours.
This paper presents new benefit–cost estimates for the Tulsa universal pre-K program. These calculations are based on estimated effects, from two recent papers, of Tulsa pre-K on high-school graduation rates and college attendance rates of students who were in kindergarten in the fall of 2006. In the current paper, educational effects from these prior papers are used to infer lifetime earnings effects. Our conservative estimates suggest that per pre-K participant, the present value of earnings effects in 2021 dollars is $25,533, compared with program costs of $9,628, for a benefit–cost ratio of 2.65. Compared to prior benefit–cost studies of Tulsa pre-K, this benefit–cost ratio is below what was predicted from Tulsa pre-K’s effects on kindergarten test scores, but above what was predicted from Tulsa pre-K’s effects on grade retention by ninth grade. This fading and recovery of predicted pre-K effects as children go through K-12 and then enter adulthood is consistent with prior research. It suggests that pre-K may have important effects on “soft skills,” such as persisting in school, and reminds us that short-term studies of pre-K provide useful information for public policy.
The literature on critical consciousness (CC) has seen rapid growth in the past ten years. However, the literature has given very little attention to CC in preadolescent children. In this chapter, we contend that the sociopolitical and civic elements of early to middle childhood development have been understudied. Emphasizing the familial, social, and educational systems that structure the lives of young children, we elaborate on the evidence that young children hold the capacity for understanding social inequities, becoming empowered to work for social change, and acting against injustice, and we provide concrete examples of how CC might be identified and measured at different stages of the early childhood developmental period. In addition, we show that the structural emphasis of the CC literature and related literatures (e.g., work on critical race theory) adds much-needed context to the study of bias and stereotyping in early childhood.
There was no previous meta-analysis investigating the efficacy/tolerability of psychostimulants for symptoms of attention-deficit hyperactivity disorder (ADHD) in preschool children.
Methods
Databases including PubMed, the Cochrane Library, EMBASE, ScienceDirect, and ClinicalTrials.gov were searched from inception to March 2022 for randomized controlled trials (RCTs) on therapeutic efficacy of psychostimulants against ADHD symptoms in preschool children (age ≤6 years) compared with placebos. Primary outcomes were (a) changes in ADHD symptoms evaluated by validated rating scales from parents’/teacher’s observation, or (b) post-intervention improvements in neuropsychological performance. Secondary outcomes were risks of adverse events.
Results
Meta-analysis of nine eligible trials including 544 preschool children (mean age=4.86 years, female=11.98%, median treatment duration=4.33 weeks) supported the efficacy of psychostimulants against global symptoms from observations of parents (Hedges’ g=0.6152, p<0.0001) and teachers (Hedges’ g=0.6563, p=0.0039). Efficacy of psychostimulants was also noted against symptoms of inattention and hyperactivity/impulsivity, especially the latter (i.e., main symptoms in preschool children). Moreover, male gender, older age, and longer treatment duration were associated with better efficacy. Regarding adverse events, only the risk of poor appetite was higher in the psychostimulant group (odds ratio [OR]=2.39). However, the qualities of evidence were low to very low, indicating potential discrepancy between the true and estimated effect.
Conclusions
Our results showed that psychostimulants might be beneficial for preschool children with ADHD, especially hyperactivity/impulsivity from teachers’ observation, with tolerable side effects. Nevertheless, the true magnitude of the effect needs to be confirmed with more research due to low to very low certainty of the evidence.
Aggression is a transdiagnostic indicator of risk and represents one of the most common reasons children are referred for mental health treatment. Theory and research highlight the impact of maternal invalidation on child aggression and suggest that its influence may vary based on differences in child physiological reactivity. Moreover, the interaction between these risk factors may be particularly pronounced among children of mothers with emotion regulation (ER) difficulties. The current study examined the independent and interactive effects of maternal invalidation and child physiological reactivity to frustration on teacher-reported aggression in an at-risk sample of preschool children.
Method
Participants included 77 mothers (Mage = 33.17 years, s.d. = 4.83; 35% racial/ethnic minority) and their children (Mage = 42.48 months; s.d. = 3.78; 56% female; 47% racial/ethnic minority). Groups of mothers with and without clinician-rated ER difficulties reported on maternal invalidation, and child respiratory sinus arrhythmia (RSA) was assessed continuously during a frustration task as an indicator of physiological reactivity. Teachers or daycare providers reported on child aggression.
Results
Results demonstrated positive associations between maternal ER difficulties and both maternal invalidation and child RSA reactivity to frustration. As expected, the interaction between maternal invalidation and child RSA reactivity was significant, such that higher maternal invalidation and greater child RSA reactivity to frustration predicted more aggression in a daycare or preschool setting. Importantly, this effect was demonstrated while controlling for demographic covariates and baseline RSA.
Conclusions
Findings are in line with diathesis–stress and biosocial models of risk and point to multiple targets for prevention and early intervention.
Preschool psychiatric symptoms significantly increase the risk for long-term negative outcomes. Transdiagnostic hierarchical approaches that capture general (‘p’) and specific psychopathology dimensions are promising for understanding risk and predicting outcomes, but their predictive utility in young children is not well established. We delineated a hierarchical structure of preschool psychopathology dimensions and tested their ability to predict psychiatric disorders and functional impairment in preadolescence.
Methods
Data for 1253 preschool children (mean age = 4.17, s.d. = 0.81) were drawn from three longitudinal studies using a similar methodology (one community sample, two psychopathology-enriched samples) and followed up into preadolescence, yielding a large and diverse sample. Exploratory factor models derived a hierarchical structure of general and specific factors using symptoms from the Preschool Age Psychiatric Assessment interview. Longitudinal analyses examined the prospective associations of preschool p and specific factors with preadolescent psychiatric disorders and functional impairment.
Results
A hierarchical dimensional structure with a p factor at the top and up to six specific factors (distress, fear, separation anxiety, social anxiety, inattention-hyperactivity, oppositionality) emerged at preschool age. The p factor predicted all preadolescent disorders (ΔR2 = 0.04–0.15) and functional impairment (ΔR2 = 0.01–0.07) to a significantly greater extent than preschool psychiatric diagnoses and functioning. Specific dimensions provided additional predictive power for the majority of preadolescent outcomes (disorders: ΔR2 = 0.06–0.15; functional impairment: ΔR2 = 0.05–0.12).
Conclusions
Both general and specific dimensions of preschool psychopathology are useful for predicting clinical and functional outcomes almost a decade later. These findings highlight the value of transdiagnostic dimensions for predicting prognosis and as potential targets for early intervention and prevention.
This study investigated the transactional relations between vocabulary and disruptive behaviors (DB; physical aggression and opposition/rule breaking/theft and vandalism), during the transition to formal schooling, using a community sample of 572 children. Cross-lagged panel model analyses were used to examine bidirectional relationships, comparing physical aggression to non-aggressive DB. Transactional associations between vocabulary and DB were observed, coinciding with school entry. Lower vocabulary in preschool (60mo.) was predictive of higher physical aggression scores in kindergarten. In turn, higher physical aggression in kindergarten was predictive of lower vocabulary in 1st grade. For non-aggressive DB, recurrent associations were found. Lower verbal skills in preschool (42mo.) and kindergarten predicted higher non-aggressive DB scores later in preschool and in 1st grade respectively. In turn, higher non-aggressive DB in kindergarten predicted lower vocabulary scores in 1st grade. In contrast to transactional paths from vocabulary to DB, transactional paths from DB to vocabulary observed after the transition to elementary school remained significant after controlling for comorbid hyperactivity, impulsivity and inattention behaviors, suggesting these links were specific to aggressive and non-aggressive DB. Practical implications for prevention are discussed.
This chapter approaches the topic of how adults talk to children in early childhood education settings from the perspective of socialisation, conceptualized as a dual process of learning language and institutional/cultural norms. Focusing on episodes in which teachers mediate in children’s peer conflict, it identifies two discursive practices that have been widely observed in various societies: (1) directives on what to say to peers (e.g., “Can you say, I’m sorry?”) and (2) replaying the talk of a third-party peer (e.g., “She’s asking you to lend it to her”). It is argued that these practices are important for encouraging children to use and respond to talk as social action (e.g., to apologize, to comply with another’s request), and to use talk to display affective stance (i.e. feelings, emotions, and attitudes). In addition to an analysis of interaction at the micro level, the chapter discusses the institutional and cultural norms that are potentially being socialized through these two practices. Finally, suggestions are made for pedagogy.
This article evaluates the long-term impacts of the Chicago Child-Parent Centers (CPC), a comprehensive early childhood program launched in the 1960s, on physical and mental health outcomes. This study follows a cohort of 1539 participants born in 1979–1980 and surveyed most recently at age 35–37 by employing a matched study design that included all 989 children who entered CPCs at ages 3 and 4 (1983-1985) and 550 comparison children of the same age from randomly selected schools participating in the usual district early childhood programs in kindergarten. Using propensity score weighting that addresses potential issues with differential attrition and non-random treatment assignment, results reveal that CPC preschool participation is associated with significantly lower rates of adverse health outcomes such as smoking and diabetes. Further, evaluating the economic impacts of the preschool component of the program, the study finds a benefit-cost ratio in the range of 1.35–3.66 (net benefit: $3896) indicating that the health benefits of the program by themselves offset the costs of the program even without considering additional benefits arising from increased educational attainment and reduced involvement in crime reported in earlier cost-benefit analyses. The findings are robust to corrections for multiple hypothesis testing, sensitivity analysis using a range of discount rates, and Monte Carlo analysis to account for uncertainty in outcomes.
Children with critical CHD are at risk for neurodevelopmental impairments, including delays in expressive and receptive language development. However, no study has synthesised the literature regarding language abilities in children with this condition.
Objective:
We summarised the literature regarding expressive and receptive language in preschool children with critical CHD.
Data sources:
MEDLINE, Embase, Scopus, Child Development and Adolescent Studies, ERIC, PsycINFO, and CINAHL.
Study selection:
We included studies published between January, 1990 and 1 July, 2021, focused on children aged ≤5 years with critical CHD requiring a complex cardiac procedure at age <1 year. Language ability was documented using standardised, validated tools assessing both expressive and receptive language outcomes.
Data extraction:
Data (study, patient and language characteristics, and results) were extracted by two reviewers.
Results:
Seventeen studies were included. Among children 2–5 years old with critical CHD, there were statistically significant deficits in overall (standardised mean difference: –0.46; 95 % confidence interval: –0.56, –0.35), expressive (standardised mean difference: –0.45;95 % confidence interval: –0.54, –0.37), and receptive (standardised mean difference: –0.32; 95 % confidence interval: –0.40, –0.23) language compared to normative data. Results reported as medians were similar to meta-analysis findings. Subgroup analysis showed that children with univentricular physiology had lower language scores than children with biventricular physiology.
Conclusions:
Preschool children with critical CHD had statistically significantly lower language outcomes compared to expected population norms. Healthcare professionals should test early and often for language deficits, referring to individually tailored supports.
Describe nutrition and physical activity practices, nutrition self-efficacy and barriers and food programme knowledge within Family Child Care Homes (FCCH) and differences by staffing.
Design:
Baseline, cross-sectional analyses of the Happy Healthy Homes randomised trial (NCT03560050).
Setting:
FCCH in Oklahoma, USA.
Participants:
FCCH providers (n 49, 100 % women, 30·6 % Non-Hispanic Black, 2·0 % Hispanic, 4·1 % American Indian/Alaska Native, 51·0 % Non-Hispanic white, 44·2 ± 14·2 years of age. 53·1 % had additional staff) self-reported nutrition and physical activity practices and policies, nutrition self-efficacy and barriers and food programme knowledge. Differences between providers with and without additional staff were adjusted for multiple comparisons (P < 0·01).
Results:
The prevalence of meeting all nutrition and physical activity best practices ranged from 0·0–43·8 % to 4·1–16·7 %, respectively. Average nutrition and physical activity scores were 3·2 ± 0·3 and 3·0 ± 0·5 (max 4·0), respectively. Sum nutrition and physical activity scores were 137·5 ± 12·6 (max 172·0) and 48·4 ± 7·5 (max 64·0), respectively. Providers reported high nutrition self-efficacy and few barriers. The majority of providers (73·9–84·7 %) felt that they could meet food programme best practices; however, knowledge of food programme best practices was lower than anticipated (median 63–67 % accuracy). More providers with additional staff had higher self-efficacy in family-style meal service than did those who did not (P = 0·006).
Conclusions:
Providers had high self-efficacy in meeting nutrition best practices and reported few barriers. While providers were successfully meeting some individual best practices, few met all. Few differences were observed between FCCH providers with and without additional staff. FCCH providers need additional nutrition training on implementation of best practices.
The aim of the research is to examine the environmental awareness and attitudes towards the environment of 5–6-year-old children attending nature-centred private kindergartens and public kindergartens. The study group of the descriptive research that used a screening model consists of 48 children from nature-centred Private Maki Kindergartens and 48 children from public kindergartens in the province of Balikesir in the 2020–2021 academic year. A Personal Information Form and Environmental Awareness and Attitude Scale for Preschool Children, developed by Soydan and Samur (International Electronic Journal of Environmental Education, 7(1), 78–97, 2017) for 60–72 months old children, were used in the study. The scale consists of two sub-dimensions as Attitude Towards Environment (15 items) and Environmental Awareness (11 Items) and 26 pictures. The Cronbach α coefficients of the Environmental Awareness (.74) and Attitude (.78) Scale for Preschool Children and the overall scale (.82) were calculated. The data were collected by the researcher through one-on-one meetings with each child. The mean, mode, median, skewness and kurtosis values of the variables in the study were calculated. To determine whether the environmental awareness and environmental attitudes of the study group differ according to the school they attend, independent samples t-test was conducted. According to the results of the research, a significant difference was found in environmental attitudes and environmental awareness of children in nature-centred kindergartens compared to children in public kindergartens. Children attending public schools are less exposed to the environment. Preparing the Pre-School Education Program in an environment-friendly manner to increase the environmental awareness of children attending public schools will be effective in terms of making a difference in their attitudes towards the environment.
The present study is the first to examine the relations between participation in a public early childhood intervention (the Child-Parent Center (CPC) program) and psychological well-being (or, positive functioning) into early mid-life. Data are drawn from the Chicago Longitudinal Study (CLS), which has followed a cohort of 1,539 individuals who grew up in urban poverty for over four decades. Approximately two-thirds of the original study cohort participated in the CPC program in early childhood; the rest comprise a demographically matched comparison group. Participants’ psychological functioning at age 35–37 was assessed using the Ryff Scales of Psychological Wellbeing. Results support a positive relationship between CPC preschool participation and long-term psychological wellbeing. Moderated mediation (e.g., whether CPC effects on wellbeing differ across subgroups) and potential mechanisms across multiple social-ecological levels (according to the 5-Hypothesis Model of early intervention) are also empirically investigated. Future directions for child development research, early childhood intervention, and public policy are discussed.
To compare the prevalence of overweight or obesity (ow/ob) with WHO BMI cut-off points, International Obesity Task Force (IOTF) cut-off points and Chinese BMI criteria and examine its potential factors among preschool children in Hunan Province.
Design:
A cross-sectional survey including anthropometric measurements and questionnaires about children’s information, caregivers’ socio-demographic characteristics and maternal characteristics. χ2 tests and univariate and multivariate binary logistic regression were performed to evaluate the possible factors of ow/ob.
Setting:
Hunan, China, from September to October 2019.
Participants:
In total, 7664 children 2 to 6 years of age.
Results:
According to Chinese BMI criteria, about 1 in 7–8 children aged 2–6 years had ow/ob in Hunan, China. The overall estimated prevalence of ow/ob among 2- to 6-year-old children was significantly higher when based on the Chinese BMI criteria compared with the WHO BMI cut-off points and IOTF cut-off points. According to Chinese BMI criteria, ow/ob was associated with residing in urban areas, older age, male sex, eating snacking food more frequently, macrosomia delivery, caesarean birth, heavier maternal prepregnancy weight and pre-delivery weight.
Conclusion:
The prevalence of ow/ob in preschool children in Hunan Province remains high. More ow/ob children could be screened out according to Chinese BMI cut-offs compared with WHO and IOTF BMI criteria. In the future, targeted intervention studies with matched controls will be needed to assess the long-term effects of intervention measures to provide more information for childhood obesity prevention and treatment.
While the Research Domain Criteria (RDoC) acknowledges that environmental and developmental influences represent important elements of the RDoC framework, there is little specificity regarding how and when to systematically examine the impact of these dimensions on domains of function. The primary aims of this paper are to demonstrate the ways in which the RDoC can be expanded to include an explicit emphasis on (a) assessing within-individual change in developmental processes over time and (b) evaluating the extent to which selective and measurable environmental influences drive meaningful change during key developmental periods. We provide data from an ongoing randomized control trial as a proof of concept to highlight how repeated assessments within an experimental intervention design affords the unique opportunity to test the impact of environmental influences on within-individual change. Using preliminary data from 77 mother–child dyads repeatedly assessed across 12 months during the sensitive preschool period, we demonstrate the impact of change in maternal emotion regulation (ER) on within-individual growth in child ER and link that growth to fewer teacher-reported externalizing problems. In line with this Special Issue, findings are discussed within the context of expanding and clarifying the existing RDoC framework to explicitly incorporate environmental and developmental dimensions.
