Measuring Young Children's Executive Function and Self-Regulation in Classrooms and Other Real-World Settings

Adaptation and psychometric properties of the Head-Toes-Knees-Shoulders task in young Iranian children

Executive functions (EF) lay the foundation for healthy development. However, few reliable and valid measures of EF have been developed among children in less developed countries such as Iran. The present study addressed this gap by examining the factor structure, score variation, and psychometric properties of a short EF task, the Head-Toes-Knees-Shoulders (HTKS), among children from two metropolitan cities (Isfahan and Tehran) in Iran. Participants (N = 693; 58% male; Mage = 5.88 years) were recruited through a convenience sampling approach and tested with the HTKS along with other performance-based EF measures and parent reports of EF difficulties. Confirmatory factor analyses showed that both one-factor and two-factor structures were acceptable and that a one-factor solution was optimal. Results demonstrated significant variability in scores and age-related differences in EF skills, with higher scores observed in older children. The task indicated acceptable internal consistency, interrater agreement, and test-retest stability. For construct validity, the HTKS was significantly related to other performance-based measures of EF, tapping into working memory, cognitive flexibility, and planning skills after controlling for child's age, gender, parental education, and city. Together, these findings underscore the promise of the HTKS task as a brief, economical, and easily administered EF task that reliably and validly captures variation in EF skills among Iranian children.

A short executive functioning questionnaire in the context of early childhood screening: psychometric properties

Early childhood executive functioning (EF) predicts later adjustment and academic achievement. However, measuring EF consistently and efficiently across settings in early childhood can be challenging. Most researchers use task-based measures of EF, but these methods present practical challenges that impede implementation in some settings. The current study of 380 3-5-year-old children in the United States evaluated the psychometric properties of a new 14-item parent-reported measure of EF in a diverse urban school district. This questionnaire aimed to capture a normative range of EF skills in ecologically valid contexts. There was evidence for two specific subscales - one that measures children's EF challenges and another that measures children's EF skills. Results suggested that several items demonstrated differential item functioning by age and race. After adjusting for measurement differences across demographic groups and controlling for age at screening, the EF challenges subscale was more strongly related to task-based measures of EF than was the EF skills subscale. EF challenges predicted third-grade math achievement, controlling for demographic variables and a performance-based measure of children's early cognitive and academic skills. Results suggest that this parent report of EF could be a useful and effective early childhood screening tool.

Socioeconomic Status and Childhood Executive Function: Differing Conceptualizations, Diverse Assessments, and Decontextualized Investigations

Developing the ability to regulate actions, thoughts, and emotions is necessary for successfully engaging in goal-directed activities, which form the essence of success in many life situations. In this regard, executive function (EF), as an aspect of these top-down control processes, has been the subject of inquiry in many developmental studies aiming to identify its link with various other aspects of a child's life, including family socioeconomic status (SES). This article presents a critical look at the association between family SES and childhood EF by reviewing studies that provide contrasting perspectives compared to the generally reported positive correlation between these two constructs. We first address the various aspects of assessing SES and childhood EF, emphasizing their multifaceted nature. Next, we discuss the interplays between different components of these two constructs, especially as it unfolds in various cultural contexts. Finally, we conclude by discussing mainly neglected lines of research that could further improve our understanding of the extent of socioeconomic impacts on child development, specifically regarding executive function. Considering these lines of research is a necessary step to a more accurate analysis of the link between socioeconomic factors and childhood executive function.

Links between socioeconomic position and cognitive and behavioral regulation in adolescence: The role of pubertal development

Adolescent cognitive and behavioral regulation is influenced by multidimensional and multidirectional processes within and across biological and contextual systems that shift throughout development. Key among these influences are distal processes such as early life socioeconomic position (SEP), and proximal processes such as pubertal development, but questions remain concerning how links between SEP, pubertal development, and cognitive and behavioral regulation accumulate and unfold over adolescence. In the current study, and in line with Dr. John Schulenberg's foundational work, direct associations between SEP, puberty, and adolescent cognitive and behavioral regulation were examined; then pubertal timing and tempo were considered as moderators and mediators of links between SEP and adolescent cognitive and behavioral regulation. Data were drawn from the NICHD Study of Early Child Care and Youth Development, a longitudinal study of 970 youth (52% male; 80% White, 13% Black, and 7% another race/ethnicity). Cognitive and behavioral regulation was measured using direct assessments of working memory, planning, risky decision-making, and impulse control at age 15. SEP included maternal education and family income-to-needs and was averaged from birth to 54 months old; estimates of pubertal timing and tempo were derived using logistic growth curve models from age 9 to age 15. SEP was directly associated with cognitive and behavioral regulation. Pubertal development tended to moderate those links, but rarely mediated them. Specifically, socioeconomic disadvantage along with earlier timing or faster tempo tended to be associated with worse cognitive and behavioral regulation. Overall, findings suggest that pubertal timing and tempo may exacerbate existing environmental constraints.

Evidence of validity of the Head-Toes-Knees-Shoulders Revised (HTKS-R) for Brazilian children

This study aims to examine the reliability and validity of the Head-Toes-Knees-Shoulders Revised (HTKS-R) as a measure of self-regulation in Brazilian children aged 3-5. The early childhood period is crucial for laying the foundations for personal, social and cognitive functioning, influencing development throughout life. Self-regulation, a malleable construct, plays a vital role in academic performance and behaviors throughout life. The HTKS-R, a widely used measure, assesses behavioral self-regulation, including cognitive flexibility, working memory and inhibitory control. The study included 379 children between the ages of 3 and 5 from a variety of backgrounds. Data were collected using the HTKS-R, a standardized self-report measure that integrates executive functions into a game to assess self-regulation. Exploratory Graphical Analysis (EGA) and Confirmatory Factor Analysis (CFA) were employed to analyze the data. The results of the EGA and BootEGA indicated a unidimensional structure for the HTKS-R, confirming its internal consistency and stability. The CFA supported the fit of the unidimensional model, demonstrating the test's construct validity. The HTKS-R showed factorial invariance between genders. The results suggest that the HTKS-R is a reliable and valid measure of self-regulation in Brazilian children aged 3-5. The applicability of the test in different age groups and environments provides valuable information about children's self-regulation skills. The study contributes to the literature by validating the HTKS-R in the Brazilian context and highlights its potential for assessing self-regulation in diverse populations.

Parasympathetic Regulation and Maternal Parenting as Longitudinal Predictors of Preschooler Inhibitory Control

Measures of parasympathetic regulation, such as respiratory sinus arrhythmia (RSA), predict executive function outcomes, including inhibitory control, across childhood. Respiratory sinus arrhythmia augmentation tends to be associated with more maladaptive outcomes compared to RSA suppression, but the literature regarding RSA profiles and inhibitory control development across infancy and early childhood is contradictory. The goal of our current study was to examine the longitudinal and interactive effects of infant RSA during a frustrating task with negative maternal characteristics on inhibitory control during early childhood. Participants included 410 children (209 girls, 77.6% White, 92.9% non-Hispanic) and their mothers. With small to moderate effect sizes (r 2 range from 0.124 to 0.143), we demonstrated that maternal negative affect when children were 36-months-old moderated the association between 10-month-old RSA during a frustrating task and 48-month-old inhibitory control, such that RSA suppression predicted higher levels of inhibitory control, but only when mothers exhibited high levels of negative affect. Our results highlight the biosocial framework under which child inhibitory control develops.

Effect of the Partners in Play Intervention on Parents' Autonomy-Supportive Guiding Behaviour and Children's Self-Regulation

Compelling evidence supports the foundational importance of early self-regulation (SR). It also supports parents in the home environment as having the foremost influence on early development. Yet, prevailing approaches to support early SR growth have tended to leverage early education and clinical settings. Partners in Play (PiP) was developed as a sustainable approach for parents to learn how and when to support children through experiences of self-regulation challenges in the home learning environment. This study reports the first randomised control trial evaluation of the PiP program, with 21 parent-child dyads (consisting of twelve girl-mother dyads, eight boy-mother dyads, and one boy-father dyad; mean child age = 4.12 years, SD = 0.65). Dyads were randomised to a PiP intervention group (n = 10), which entailed four online parent information sessions and four out-of-home guided practice dyadic play sessions across 8 weeks, or an active control group (n = 11). The primary outcome was parent autonomy support, and the secondary outcome was child SR. Results indicated a significant increase in parents' use of autonomy support and a non-significant but moderate-sized effect on child SR. This innovative proof-of-concept program and evaluation provides a roadmap for effecting change in parental support during children's play, to the prospective benefit of important abilities such as child SR. Analyses show promise for a parent-based model toward parent behaviour change and child SR improvement.

Assessing basic motor competences, physical fitness, and executive function in 4-5-year-old children: a longitudinal study in a primary care setting

BACKGROUND

To evaluate the progression of physical fitness (PF), basic motor competence (BMC), and executive function (EF) over one year in children aged 4-5 years at a health center.

METHODS

In this longitudinal analysis, children's BMC was evaluated using the MOBAK KG test for object and self-movement. The PREFIT Battery gauged PF through handgrip strength, standing long jump, and other fitness measures, while the Early Years Toolbox appraised EF.

RESULTS

Adjustments for confounding factors showed notable improvements in BMC, particularly in object movement (OM; mean difference 0.789, p = 0.044) and self-movement (SM; mean difference 0.842, p = 0.037), with overall MOBAK scores also increasing (mean difference 1.632, p = 0.018). Enhancements in the standing long jump (mean difference 9.036 cm, p = 0.014) and EF tasks "Mr. Ant" (mean difference 0.669, p < 0.001) and "Go/No-Go" (mean difference 0.120, p < 0.001) were evident, signifying substantial BMC gains and some progress in PF and EF.

CONCLUSION

This research underscores the positive impact of regular training on BMC and PF in young children. Significant BMC development and associated improvements in PF and EF over the study period highlight the importance of structured activities in early childhood. These findings advocate for standardized training programs to enhance childhood health and encourage active lifestyles.

Principles for Adapting Assessments of Executive Function across Cultural Contexts

Direct assessments of executive functions (EFs) are increasingly used in research and clinical settings, with a central assumption that they assess "universal" underlying skills. Their use is spreading globally, raising questions about the cultural appropriateness of assessments devised in Western industrialized countries. We selectively reviewed multidisciplinary evidence and theory to identify sets of cultural preferences that may be at odds with the implicit assumptions of EF assessments. These preferences relate to motivation and compliance; cultural expectations for interpersonal engagement; contextualized vs. academic thinking; cultural notions of speed and time; the willingness to be silly, be incorrect, or do the opposite; and subject-matter familiarity. In each case, we discuss how the cultural preference may be incompatible with the assumptions of assessments, and how future research and practice can address the issue. Many of the cultural preferences discussed differ between interdependent and independent cultures and between schooled and unschooled populations. Adapting testing protocols to these cultural preferences in different contexts will be important for expanding our scientific understanding of EF from the narrow slice of the human population that has participated in the research to date.

The Protective Effects of Parent-Child Emotion Dialogues for Preschoolers Exposed to Intimate Partner Violence

Exposure to intimate partner violence (IPV) during early childhood is associated with self-regulation difficulties. Caregivers can facilitate children's self-regulation through emotion-focused conversations about past experiences, buffering downstream effects. However, caregivers experiencing violence may avoid distressing emotions activated by such conversations. This paper explores two different models of relational stress responses, one involving indirect effects (i.e. spillover effects) and the other moderation (i.e. buffering effects). Mothers (n = 117), oversampled for violence exposure, self-reported on IPV and participated in an emotional reminiscing task with children (aged 3-5 years); narratives were coded for maternal sensitive guidance. Maternal sensitive guidance was related to children's self-regulation. Sensitive guidance did not have indirect effects in the association between IPV exposure and children's self-regulation, but did buffer the association between physical IPV and self-regulation; this pattern did not hold for psychological IPV. Results suggest sensitive guidance during reminiscing may promote self-regulation in contexts of high IPV.

Predictive Validity of the NIH Toolbox Executive Function Measures with Developmental Extensions from Early Childhood to Third Grade Achievement

   The National Institutes of Health Toolbox includes two executive function measures: the Dimensional Change Card Sort (DCCS) and the Flanker Inhibitory Control and Attention Test. Developmental extension (Dext) versions were created with easier levels for younger and more disadvantaged children. Although research on early (E-Prime) and later (iPad) versions of the Dext measures demonstrated their short-term validity, this study investigated their longer-term predictive validity. Participants included 402 children (Mage = 55.02 months) who completed the DCCS-Dext and Flanker-Dext (E-Prime) during early childhood screening and achievement tests in the third grade. Both measures significantly predicted math and reading scores among diverse groups of children.

The Relations Between an Inventory-Based Measure of Executive Function and Impulsivity Factors in Alcohol- and Cannabis-Relevant Outcomes

OBJECTIVE

While the lack of relation between performance- and inventory-based executive function (EF) measures is well documented, there remains ambiguity between self-report EFs and closely related constructs (e.g., impulsivity) assessed via the same method. The degree of convergence between purported EF measures with similar yet distinct constructs contain important theoretical implications for available EF assessment strategies and their construct validity. A newer measure of EF, the Behavior Regulation Inventory of Executive Functions-Adult (BRIEF-A), allows for more direct comparisons to self-reported measures of impulsivity, such as the commonly used Urgency, Planning, Perseverance, Sensation Seeking-Positive Urgency (UPPS-P) assessment.

METHOD

The present study used factor analysis and hierarchical regression to explore the associations between the BRIEF-A and UPPS-P, using alcohol and cannabis consumption across various outcomes (i.e., quantity-frequency and consequences) as an external criterion. Participants were 339 undergraduate students (Mage = 19.35; Female = 63%) from a large southwestern university.

RESULTS

The BRIEF-A and UPPS-P demonstrated strong correlations at both higher- and lower order facets. While the BRIEF-A was a significant correlate to many substance use outcomes, these relations were generally weaker than those seen with the UPPS-P. Hierarchical regression suggested limited contributions of the BRIEF-A over and above the UPPS-P.

CONCLUSIONS

Overall, this study suggested substantial overlap between impulsigenic factors and EFs when measured by self-report, and limited utility of EF measures to account for unique variance with substance use outcomes in this sample.

Development and validation of a self-regulation scale within the German version of the Early Development Instrument

BACKGROUND

Early childhood self-regulation (SR) is key for many health- and education-related outcomes across the life span. Kindergarten age is a crucial period for SR development, and within this developmental window, potential SR difficulties can still be compensated for (e.g., through interventions). However, efficient measurement of SR through brief, comprehensive, and easy-to-use instruments that identify SR difficulties are scarce. To address this need, we used items of an internationally applied kindergarten teacher questionnaire-the Early Development Instrument (EDI) - to develop and validate a specific SR measurement scale.

METHODS

The psychometric evaluation and validation of the selected SR-items was performed in data collected with the German version of the EDI (GEDI), in two independent data sets - (a) the development dataset, with 191 children, and b) the validation dataset, with 184 children. Both included three- to six-year-old children and contained retest and interrater reliability data. First, three independent raters-based on theory-selected items eligible to form a SR scale from the two SR-relevant GEDI domains "social competence" and "emotional maturity". Second, exploratory and confirmatory factor analysis using structural equation modeling examined the item structure across both data sets. This resulted in a defined SR scale, of which internal consistency, test-retest and interrater reliability, cross-validation, and concurrent validity using correlation and descriptive agreements (Bland-Altman (BA) plots) with an existing validated SR-measuring instrument (the Kindergarten Behavioral Scales) were assessed.

RESULTS

Confirmatory factor analysis across both data sets yielded the best fit indices with 13 of the GEDI 20 items initially deemed eligible for SR measurement, and a three-factor structure: a) behavioral response inhibition, b) cognitive inhibition, c) selective or focused attention (RMSEA: 0.019, CFI: 0.998). Psychometric evaluation of the resulting 13-item-GEDI-SR scale revealed good internal consistency (0.92), test-retest and interrater reliability (0.85 and 0.71, respectively), validity testing yielded stability across populations and good concurrent validity with the Kindergarten Behavioral Scales (Pearson correlation coefficient: mean 0.72, range 0.61 to 0.84).

CONCLUSIONS

The GEDI contains 13 items suitable to assess SR, either as part of regular EDI developmental monitoring or as a valid stand-alone scale. This short 13-item (G)EDI-SR scale may allow early detection of children with SR difficulties in the kindergarten setting in future and could be the basis for public health intervention planning. To attain this goal, future research should establish appropriate reference values using a representative standardization sample.

Contributions of socioeconomic status and cognition to emotion processes and internalizing psychopathology in childhood and adolescence: A systematic review

This systematic review evaluated evidence from 25 manuscripts regarding three possible relationships of socioeconomic disadvantage (SESD) and cognition to emotion knowledge (EK), emotion regulation (ER), and internalizing psychopathology (IP) across development; a) independent contributions of disadvantage and cognition; b) cognition mediates relations of disadvantage; or c) cognition moderates' relations of disadvantage. Results support associations between SESD and cognition to emotion that differ by cognitive domain and developmental epoch. For EK, in early and middle childhood language and executive functions contribute to EK independent of SESD, and early childhood executive functions may interact with socioeconomic status (SES) to predict prospective EK. Regarding ER, language contributes to ER independent of SES across development and may mediate associations between SES and ER in adolescence. Regarding IP, SES, language, executive function, and general ability have independent contributions to IP across development; in adolescence executive function may mediate or moderate associations between SES and IP. Findings highlight the need for nuanced and developmentally sensitive research on the contributions of SESD and domains of cognition to emotion.

Better together: novel methods for measuring and modeling development of executive function diversity while accounting for unity

INTRODUCTION

Executive functions (EFs) are linked to positive outcomes across the lifespan. Yet, methodological challenges have prevented precise understanding of the developmental trajectory of their organization.

METHODS

We introduce novel methods to address challenges for both measuring and modeling EFs using an accelerated longitudinal design with a large, diverse sample of students in middle childhood (N = 1,286; ages 8 to 14). We used eight adaptive assessments hypothesized to measure three EFs, working memory, context monitoring, and interference resolution. We deployed adaptive assessments to equate EF challenge across ages and a data-driven, network analytic approach to reveal the evolving diversity of EFs while simultaneously accounting for their unity.

RESULTS AND DISCUSSION

Using this methodological paradigm shift brought new precision and clarity to the development of these EFs, showing these eight tasks are organized into three stable components by age 10, but refinement of composition of these components continues through at least age 14.

A meta-analysis of the validity of the Head-Toes-Knees-Shoulders task in predicting young children's academic performance

The present study represents the first meta-analytic synthesis of the utility of a widely used early-childhood self-regulation measure, the Head-Toes-Knees-Shoulders task, in predicting children's academic achievement. A systematic review of the literature yielded 69 studies accessed from peer reviewed journals representing 413 effect sizes and 19,917 children meeting the complete set of inclusion and exclusion criteria. Robust variance analysis demonstrated that the Head-Toes-Knees-Shoulders task was a consistent predictor of children's academic achievement across literacy, oral language, and mathematical outcomes. A moderator analysis indicated that in accordance with prior research, the Head-Toes-Knees-Shoulders task was more strongly associated with children's mathematics performance relative to their performance on language and literacy measures. The results of this meta-analysis suggest that the Head-Toes-Knees-Shoulders task demonstrated statistically significant, positive associations with children's overall academic performance. These associations remained stable across different participant and measurement factors and are comparable to meta-analyses examining the self-regulation and academic association with multiple measures of self-regulation and executive function.

Contribution of sustained attention abilities to real-world academic skills in children

Sustained attention is a critical cognitive ability that improves over the course of development and predicts important real-world outcomes, such as academic achievement. However, the majority of work demonstrating links between sustained attention and academic skills has been conducted in lab-based settings that lack the ecological validity of a more naturalistic environment, like school. Further, most studies focus on targeted academic measures of specific sub-skills and have not fully examined whether this relationship generalizes to broad measures of academic achievement that are used for important, real-world, academic advancement decisions, such as standardized test scores. To address this gap, we examined the role of sustained attention in predicting targeted and broad assessments of academic abilities, where all skills were assessed in group-based environments in schools. In a sample of over 700 students aged 9-14, we showed that attention was positively related to performance on targeted assessments (math fluency and reading comprehension), as well as broad academic measures (statewide standardized test scores). Moreover, we found that attention was more predictive of targeted math sub-skills compared to assessments of broad math abilities, but was equally predictive of reading for both types of measures. Our findings add to our understanding of how sustained attention is linked to academic skills assessed in more 'real-world', naturalistic school environments and have important implications for designing tools to support student's academic success.

The effects of 9 months of formulated whole-egg or milk powder food products as meal or snack replacements on executive function in preadolescents: A randomized, placebo-controlled trial

BACKGROUND

Elevated brain choline is associated with better executive functions in preadolescents. Manipulating dietary choline prospectively in preadolescents using egg supplementation could improve executive functions via effects on brain cellular and neurotransmitter functions.

OBJECTIVES

We tested the 9-month impacts of egg supplementation on executive functions. It was hypothesized that preadolescents who consumed meal or snack replacement products containing powder made from whole eggs would have the largest improvements in executive functions after 9 months compared to those consuming similar products with either added milk powder or gelatin as a placebo.

METHODS

A randomized, parallel-group, double-blinded, placebo-controlled trial design was used. The executive functions of 122 preadolescents (58 females) aged 9-13 were analyzed before and after the 9-month intervention. The primary outcomes were 3 NIH Toolbox-Cognitive Battery measures of executive function: mental flexibility, working memory, and selective attention and inhibitory control. Participants were randomized to consume food products with either: 1) whole egg powder; 2) milk powder; or 3) gelatin as a placebo, all matched on macronutrient content and used as replacements for commonly consumed foods (i.e., waffles, pancakes, macaroni and cheese, ice cream, and brownies). Hypothesis testing used mixed-effects models that included physical activity and sleep scores as covariates.

RESULTS

A statistically significant group × time interaction for selective attention and inhibitory control was found (P = 0.049) for the milk group. This interaction resulted from no change for the placebo group and an improvement in selective attention and inhibitory control performance for the milk group by a T-score of 5.8; the effect size (d) was 0.44 SD units. Other comparisons were statistically insignificant.

CONCLUSIONS

Consumption of foods with added milk powder as a replacement for snacks or meals for 9 months improves selective attention and inhibitory control in preadolescents. Replacement of foods with added whole egg powder does not impact 9-month changes in preadolescent executive functions. This trial was registered at clinicaltrials.gov as NCT03739424.

Advancing Educational Research on Children’s Self-Regulation With Observational Measures

Self-regulation is crucial for children’s development and learning. Almost by convention, it is assumed that self-regulation is a relatively stable skill, and little is known about its dynamic nature and context dependency. Traditional measurement approaches such as single direct assessments and adult reports are not well suited to address questions around variations of self-regulation within individuals and influences from social-contextual factors. Measures relying on child observations are uniquely positioned to address these questions and to advance the field by shedding light on self-regulatory variability and incremental growth. In this paper, we review traditional measurement approaches (direct assessments and adult reports) and recently developed observational measures. We discuss which questions observational measures are best suited to address and why traditional measurement approaches fall short. Finally, we share lessons learned based on our experiences using child observations in educational settings and discuss how measurement approaches should be carefully aligned to the research questions.

Assessment of executive functions in school-aged children: A narrative review

Introduction

In the past three decades, there has been increasing interest in assessing children's Executive Functions (EF). However, studies on the conceptualization and operationalization of this construct are incongruent and guidance for clinicians and researchers aiming to assess EF is insufficient due to measurement variability.

Aims

The purpose of this article was to examine current theories and models of EF in children, identify their assessment instruments, issues, and challenges, and discuss their impact on children's cognitive, behavioral, social and/or emotional development.

Methods

This narrative review reflected on English and French scholarly articles on EF assessment in children. References were identified through searches of PubMed, Medline, ScienceDirect, Google Scholar, and APA PsychNet throughout the last two decades up to June 2022.

Results

There are commonalities despite divergence in the definition and operationalization of EF. Assessment of EF requires psychometric tests as well as rating scales that must be integrated and interpreted considering the child's biological makeup, environmental background, and cultural specificities.

Conclusion

Current EF theories, assessment tools, issues, and challenges were discussed in addition to the impact of their components' dysfunctions on children's development. Further studies should be conducted to develop new measurement methods and technologies to improve the ecological and ethological validity of youth assessment, treatment, and interventions.

The unique relevance of executive functions and self-regulation behaviors for understanding early childhood experiences and preschoolers' outcomes in rural Pakistan

Performance-based measures of children's executive functions (EFs) do not capture children's application of these skills during everyday emotionally-laden and socially-mediated interactions. The current study demonstrates the value of using assessor report of self-regulation behaviors (inhibitory control and positive affect/engagement) in addition to EF tasks when studying early childhood experiences and development in a rural lower-middle-income country setting. In a sample of 1302 disadvantaged 4-year-olds living in rural Pakistan, we found that directly assessed EFs were significantly related to assessor observations of children's inhibitory control and positive affect/engagement during a structured assessment protocol. However, EFs and two types of self-regulation behaviors demonstrated unique associations with children's (1) contextual experiences, as indexed by family socio-economic resources, participation in parenting interventions, and children's physical growth; and (2) age-salient developmental outcomes, as indexed by direct assessment of pre-academic skills and maternal report of prosocial behaviors and behavior problems. First, family wealth uniquely predicted only observed positive affect/engagement, whereas maternal education uniquely predicted only EFs. Second, children's antecedent linear growth was a significant predictor of both EFs and positive affect/engagement, but exposure to an enhanced nutrition intervention during the first 2 years of life and preschoolers' hair cortisol concentration were associated only with observed self-regulation behaviors. Finally, both EFs and observed positive affect/engagement uniquely predicted children's pre-academic skills. In contrast, only assessors' ratings of positive affect/engagement uniquely predicted maternal report of prosocial behaviors and only assessors' ratings of inhibitory control uniquely predicted maternal report of behavioral problems.

Understanding patterns of heterogeneity in executive functioning during adolescence: Evidence from population-level data

Executive functioning (EF) is fundamental to positive development. Yet, little is known about how to best characterize constellations of EF skills that may inform disparate associations between EF and behavior during adolescence. In the current study, cross-validated latent profile analysis (LPA) was used to derive profiles of EF based on measures of inhibitory control, working memory, and cognitive flexibility using data from 11,672 youth (52.2% male, mean age = 9.91 years) in the Adolescent Brain and Cognitive Development study. Four meaningful EF profiles emerged from the data representing Average EF, High EF, Low Inhibitory Control, and Low EF. Boys, youth from low-income households, and early developing youth were more likely to be in profiles distinguished by lower EF. Profile membership also predicted differences in externalizing, internalizing, and other problem behaviors assessed one year later. Findings indicate that youth may have distinct constellations of EF skills, underscoring the need for person-centered approaches that focus on patterns of individual characteristics.

An observational approach for exploring variability in young children's regulation-related skills within classroom contexts

Prior work has conceptualized children's executive function and self-regulation skills as relatively stable across short periods of time. Grounded in long-standing contextual theories of human development, this study introduces a new observational tool for measuring children's regulatory skills across different naturally occurring situations within early childhood classrooms. Using 460 observations of 91 children (M age = 5.54 years) in 16 socio-demographically diverse Prekindergarten and Kindergarten classrooms, we found that this tool-the Regulation-Related Skills Measure (RRSM)-reliably captured observed dimensions of young children's attention control and inhibitory control, but failed to appropriately represent more "internal" regulatory processes (e.g., working memory). Associations between the RRSM and other measures of children's executive function and self-regulation (i.e., direct assessments, adult reports) were low to moderate (r = 0.03 to 0.44), suggesting these tools are likely to be complementary in that they provide overlapping but ultimately distinct information regarding children's regulatory performance. Finally, results suggested substantial within-child variation in regulatory behaviors across different situations within the classroom, with the same children demonstrating consistently stronger attention control and inhibitory control during transitions than during either teacher- or student-directed activities. These findings underscore the situationally-dependent nature of children's self-regulatory performance, with implications for both theory and practice. Future research is needed to replicate these findings in more diverse, representative samples of children.

Measuring children's behavioral regulation in the preschool classroom: An objective, sensor-based approach

Children's abilities to regulate their behaviors are critical for learning and development, yet researchers lack an objective, precise method for assessing children's behavioral regulation in their everyday environments such as their classrooms. This study tested a sensor-based approach to assess preschool children's behavioral regulation objectively, precisely, and naturalistically. Children wore accelerometer devices as they engaged in center-based play in their preschool classrooms for roughly 45 min (N = 50 children, 48% female, mean age = 4.5 years). Set to record data each second, these devices collected information about children's movement (N = 140,564 observations). From these data, the authors extracted concrete behaviors hypothesized to index behavioral regulation and compared them with teacher and observer ratings of the same. Initiating movement more frequently, staying seated in activities for shorter amounts of time, and spending a greater amount of time in motion were related to lower ratings of attention and inhibitory control by teachers and by observers of classroom group time, median r = .45, p < .01. These same objectively measured behaviors showed only weak associations with children's performance on assessments of cognitive regulation, median r = .11, p = .47. The findings indicate that ambulatory accelerometers can capture movement-based indicators of children's behavioral regulation in the classroom setting and that performance on measures of cognitive regulation does not strongly predict children's behavior in the classroom. As an unobtrusive and objective measure, actigraphy may become an important tool for studying children's behavioral regulation in everyday contexts.

Identifying Children With Self-Regulation Problems

Abstract. The Preschool Self-Regulation Questionnaire (Questionario di Valutazione dell’Autoregolazione [QUVA-p]) is a teacher-completed screening tool for assessing child dysregulation at preschool age. This study presents the psychometric properties of the questionnaire, which was investigated in a sample of 413 preschoolers. We tested for construct validity, measurement invariance across gender, subscale internal consistency, subscale convergent validity with executive control tasks (working memory, inhibitory control, and cognitive flexibility), and power to detect child differences in executive control. Results show that the factorial structure of the QUVA-p is in line with Nigg’s theoretical model of self-regulation and the subscales have good reliability. Measurement invariance is maintained across gender; the instrument reveals small but significant associations with executive control tasks, and it could be useful to detect child differences in executive control.

Development, Construct Validation, and Normalization of a New Early Childhood Self-Regulation Assessment Scale

Although there are many tools for assessing young children's self-regulation according to varied conceptual definitions and purposes, the purpose of this study was to develop, validate, and norm a Self-Regulation Assessment Scale for Early Childhood (SASEC) for directly evaluating observed behaviors of young children in naturalistic play experiences within the normal preschool environment. An exploratory sequential mixed methods research design was used. The 315 participants included 153 parents and 15 educators for the qualitative component and 147 children ages 3-5 years for the quantitative component. The analytical steps of a qualitative grounded theory research design were applied to adult participant interviews and focus group discussions, which culminated in 12 scale items for measuring a child's ability to initiate, modulate, and cease behaviors, tasks, or activities of varied complexities, social configurations, and limiting conditions. Children's SASEC scores were assessed via video recordings of play behaviors in naturalistic settings. Based on factor analysis results, the SASEC items constitute a single construct. According to the results of hierarchical linear modeling and multiple linear regression, preschool children's SASEC scores can be compared to the SASEC mean and standard deviation regardless of various demographic variables. Implications and recommendations for future work include having early childhood educators, child and youth care practitioners, counselors, parents and families, social workers, behavioral sciences researchers, and policy makers use the SASEC to measure young children's self-regulation while developing or monitoring the efficacy of generalized enhancement programs and individualized treatment plans.

Inhibitory Control in Autism Spectrum Disorders: Meta-analyses on Indirect and Direct Measures

This manuscript aimed to advance our understanding of inhibitory control (IC) in autism spectrum disorders (ASD), adopting a meta-analytic multilevel approach. The first meta-analysis, on 164 studies adopting direct measures, indicated a significant small-to-medium (g = 0.484) deficit in the group with ASD (n = 5140) compared with controls (n = 6075). Similar effect sizes between response inhibition and interference control were found, but they were differentially affected by intellectual functioning and age. The second meta-analysis, on 24 studies using indirect measures, revealed a large deficit (g = 1.334) in the group with ASD (n = 985) compared with controls (n = 1300). Presentation format, intellectual functioning, and age were significant moderators. The effect of comorbidity with ADHD was not statistically significant. Implications are discussed for IC research and practice in autism.

Examining Additive and Synergistic Relations Between Preschool Self-Regulation and Executive Function Skills: Predictions to Academic Outcomes

In the present study, we examined the extent to which teacher-rated self-regulation and directly assessed executive function skills were independently, additively, or synergistically related to academic achievement during the transition to kindergarten. The sample included 126 children (42% female; M_age = 4.73 years) from families with low incomes who participated in a larger evaluation of state-funded preschool. Regression models with children nested in their respective preschool classrooms investigated main effects and moderated effects of teacher-rated self-regulation skills manifested in preschool classroom behaviors and cognitive executive function skills assessed through direct assessments on math, literacy, and vocabulary in the spring of preschool and in the fall of kindergarten. Results revealed independent but not additive relations between executive function and math in the spring of preschool and self-regulation and literacy in the fall of kindergarten. One significant interaction emerged providing evidence for synergistic relations between teacher-rated self-regulation and directly assessed executive function for literacy at both timepoints across the transition to kindergarten. Implications for policy and practice are discussed.

Latent Profiles of Teacher-Reported Self-Regulation and Assessed Executive Function in Low-Income Community Preschools: Relations With Motor, Social, and School Readiness Outcomes

This study contributes to understandings of early childhood self-regulation and executive function, and their components, through taking a person-centered approach to investigating how these skills cluster together in children aged 4-5years. A sample of children (N=206) from preschools in low socioeconomic communities were assessed through teacher report of self-regulation and three executive function tasks at the commencement of the preschool year. Outcome variables included teacher report of social skills and behavioral problems, and children's school readiness and visual motor integration skills were directly assessed. When the scores from this low-income sample were compared to available norms, over 70% of children scored below the 50th percentile in executive function measures, approximately 20% were below average in self-regulation skills, 48% were delayed in school readiness scores, 36% had above average levels of internalizing problems, and 25% were above average in externalizing problems. A series of four latent profile models each used different measurement approaches and combinations of self-regulation and executive function components. In three of the four models (two which combined self-regulation and executive function measures and one with teacher report of self-regulation only), a high skill and low skill profile were found with 31 to 42% of children in the low profile depending on the model. Children were very similarly classified across all three models. When three executive function scores were modeled alone, a more complex three-profile solution emerged (low, moderate, and high) with 52% in the low profile. Children identified in the low profiles across all models were at greater risk of poorer school readiness, visual motor integration and social skills, and increased behavioral problems. Taken together, the findings suggest that self-regulation and executive function skills tend to cluster together at this age and in this low-income sample. Composite scores of teacher report of self-regulation are somewhat sufficient in identifying children who also have poorer executive function skills and are at risk of poorer motor, social, and school readiness outcomes. These children are an important target group for additional supports prior to school entry.

Cognition in context: Validating group-based executive function assessments in young children

The current article describes and validates a set of group-based executive function (EF) assessments for use with young children. These situational tasks involve instructing groups of young students to march to music while completing tasks that place demands on their EF abilities. These efforts were motivated by providing researchers with a set of measures that assess EF subcomponents while also accounting for the dynamic social processes present in group settings. These assessments take place in schools, are relatively simple to administer, and include multiple EF indicators. Drawing on a diverse sample of 283 kindergarteners (M_age = 5.8 years, SD = 0.38), we found that group-based EF assessments were significantly related to individually assessed EF measures and differentially predicted children's performance on standardized tests of math and reading achievement. Overall, this study represents a first step toward developing a set of group-based EF measures that are appropriate for use with young children.

The dimensionality of early executive functions in young preschoolers: Comparing unidimensional versus bidimensional models and their ecological validity

The study analyses the dimensionality of executive functions (EF) and its relationship with behavior in typically developing 3- and 4-year-old children. In study 1, confirmatory factor analysis (CFA) was used to investigate the validity of a one-factor model in 117 preschoolers. Since this model was not confirmed, a two-factor model was identified through exploratory factor analysis. In study 2, the validity of the new two-factor versus one-factor model was tested on a new sample of 128 children through a series of CFAs. The relationship between the models and specific behavioral aspects of the children was investigated. The results suggest that a bidimensional structure showed a better fit to the data and more ecological validity than a unitary structure.

The association of parent-reported executive functioning, reading, and math is explained by nature, not nurture

According to the hybrid model (van Bergen, van der Leij, & de Jong, 2014), the significant association among executive functioning (EF), reading, and math may be partially explained by parent-reported EF's role as a common risk and/or protective factor in reading and math (dis)abilities. The current study used a sample of 434 twin pairs (M_age = 12.12) from Florida to conduct genetically sensitive modeling on children's parent-reported EF, reading, and math skills to determine the common and unique etiological influences among the three domains. EF was measured through parent report and reading and math were measured with standardized test scores drawn from Florida's Progress Monitoring and Reporting Network as well as standardized parent-administered assessments collected by mail. Our trivariate Cholesky modeling showed that no matter which parent-reported EF component was modeled, the overlap of parent-reported EF with reading and math was explained by common genetic influences. Supplemental analysis suggested that this might in part be due to general parent report of problem behaviors. Additionally, significant environmental influences, with higher shared environmental overlap than previous work, were also found for reading and math. Findings indicate that poor parent-reported EF is a common cognitive risk factor for reading and math disabilities, which is driven by a shared genetic basis among all three domains.

Measurement of parental executive function in early childhood settings: Instrument reliability and validity in community-led research projects

A growing number of early childhood (EC) parenting programs target adult executive function (EF) to build responsive parenting behaviors and to promote positive child development. Although measurement of EF is well understood in academic research, little work has examined EF measurement in community settings. The present study examined psychometric properties of the Behavior Rating Inventory of Executive Function-Adult Version among 203 parents whose children were enrolled in EC programs serving under-resourced communities. We calculated Cronbach's α and mean-item correlations to test internal consistency reliability. To test factor structure, we conducted exploratory factor analysis and confirmatory factor analyses. Results suggest adequate internal consistency and that factor structures, beyond the original proposed, are appropriate for our community sample. Together, findings indicate that self-report measures of adult EF may perform differently for families experiencing adversity, raising questions about the acceptability of clinical EF tools in in underserved communities.

Relationship Between Task-Based and Parent Report-Based Measures of Attention and Executive Function in Children with Fetal Alcohol Spectrum Disorders (FASD)

A majority of children with fetal alcohol spectrum disorders (FASD) have demonstrated attention and executive function deficits as measured by both parent report measures and performance on tasks requiring sustained levels of attention. However, prior studies have consistently reported a lack of association between parental report-based and task-based performance measures. The current study investigated whether changes in performance over time within-task (i.e., first-half versus second-half) better correspond to parental reports of executive function and temperament in children with FASD. Greater differences in split-half performance during a continuous performance task were found to be associated with higher parent-reported levels of behavioral regulation and inhibitory control. These findings suggest that within-task performance differences may more accurately reflect individual differences in executive function and temperament as measured by parental report and help to further inform the way in which cognitive processes are measured in children with FASD.

Inhibitory Processes and Fluid Intelligence: a Performance at Early Years of Schooling

Inhibition constitutes one of the main executive functions and it is important to more complex skills such as fluid intelligence. Actually, there is an agreement on distinguishing three inhibitory types: perceptual, cognitive and response inhibition. Several studies show the differential engagement of these inhibitory types in different skills. However, there is no registered evidence about the differential relation of inhibitory types with fluid intelligence. This inquiry is especially important during the first school years, since in this stage, inhibitory processes would already be differentiated, and inhibitory processes and fluid intelligence are linked to the performance of children in the school setting. For these reasons, the goal of this work is to study the relation and contribution of perceptual, cognitive, and response inhibition with fluid intelligence, in children in the first years of primary school. For that purpose, a sample of children from six to eight years old (N = 178) was tested with a perceptual inhibition task (perception of similarities and differences task); a cognitive inhibition task (proactive interference task); a response inhibition task (stop signal task); and a fluid intelligence task (progressive matrices task). We observed significant correlations between perceptual and response inhibition and fluid intelligence (controlling for age), but only perceptual inhibition explains significantly part of the performance in the fluid intelligence task. This study provides data about the specific contribution, during childhood, of an inhibitory type to fluid intelligence and contributes empirical evidence in support of the non-unitary approach of inhibition.

Developing and Validating a Big-Store Multiple Errands Test

The Multiple Errands Test (MET) is an ecologically valid assessment that characterizes how executive dysfunction manifests in everyday activities. Due to the naturalistic nature of this assessment, clinicians and researchers have had to develop site-specific versions resulting in numerous published versions and making it difficult to establish standard psychometric properties. The aim of this study was to develop a standardized, community version of the MET designed to be used in large department stores meeting set criteria that would not require site specific modifications. This paper reports on the development, content validity, feasibility, and inter-rater reliability of a Big-Store MET, and the performance of healthy participants on this test. Items were selected to match previously published versions in relation to quantity and complexity. Content validity was established by having experts (n = 4) on the MET review the proposed Big-Store version and evaluate the task consistency with previously published versions. To assess feasibility of administration, and inter-rater reliability, a convenience sample of 14 community dwelling adults, self-reporting as healthy, were assessed by two trained raters. We found the Big-Store MET to be feasible to deliver (completed within 30 min, scores show variability, acceptable to participants in community environment) and inter-rater reliability to be very high (ICCs = 0.92-0.99) with the exception of frequency of strategy use. This study introduces the Big-Store MET to the literature, establishes its preliminary validity and reliability thus laying the foundation for a standardized, community-based version of the MET.

Inhibitory Processes Training for School-age Children: Transfer Effects

Inhibition refers to a basic executive component that can be conceptualized as consisted of different inhibitory processes (i.e., perceptual, cognitive and response inhibition). These processes emerge during the first years of life, and since then are involved in different relevant every day activities. Different individual and contextual factors can modulate their developmental trajectories. The possibility of train in separate ways each inhibitory process is a subject of analysis. In such a context, the aims of this work were: (a) to design, implement and evaluate training of perceptual, cognitive and response inhibition processes, in a sample of school-aged children (6 to 8 years old); and (b) to analyze near, far, short- and long-transfer effects. An experimental design with three training groups (one for each inhibitory process) and an active control group was implemented. Near transfer effects were not observed. We found effects on a visuospatial working memory task in the short term, after the training in the response and cognitive inhibition, and effects on a fluid intelligence task in both the short and long term after the training in cognitive inhibition. The results contribute to a conceptualization of multidimensional inhibitory processes and the plausibility of training them during childhood.
