Adrenocortical and autonomic cross-system regulation in youth: A meta-analysis.

Childhood and adolescence are salient periods for the development of adrenocortical and autonomic arms of the stress response system (SRS), setting the stage for subsequent health and adaptive functioning. Although adrenocortical and autonomic systems theoretically function in highly coordinated ways, the strength of the relationship between these systems remains unclear. We leveraged a multivariate mixed effects meta-analytic approach to assess associations between adrenocortical, sympathetic, and parasympathetic functioning at rest and reactivity during stress-inducing tasks across 52 studies (N = 7,671; 5-20 years old). Results suggested a modest positive relation between adrenocortical and sympathetic systems as well as between adrenocortical and parasympathetic systems. Moderation analyses indicated the strength of associations varied as a function of several methodological and sociodemographic characteristics. Environmental effects on cross-system regulation were less clear, perhaps due to underrepresentation of adverse-exposed youth in the included studies. Collectively, our findings call for greater methodological attention to the dynamical, non-linear nature of cross-system functioning, as well as the role of experience in their organization across development.

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.

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.

Reprint of: Homelessness and child protection involvement: Temporal links and risks to student attendance and school mobility.

BACKGROUND: The experience of homelessness and child protection involvement pose risks to children's school success. Elucidating processes by which these interrelated systems affect child well-being is important for guiding policy and practice. OBJECTIVE: This study examines the temporal relation between emergency shelter or transitional housing use and child protection involvement among school-aged children. We evaluated effects of both risk indicators on school attendance and school mobility. PARTICIPANT AND SETTING: Using integrated administrative data, we identified 3278 children (ages 4 to 15) whose families used emergency or transitional housing in Hennepin and Ramsey County of Minnesota during the 2014 and 2015 academic years. A propensity-score-matched comparison group of 2613 children who did not use emergency or transitional housing. METHOD: Through a series of logistic regressions and generalized estimating equations, we tested the temporal associations of emergency/transitional housing and child protection involvement as well as how both experiences affected school attendance and mobility. RESULTS: Experiences of emergency or transitional housing often proceeded or occurred concurrently with child protection involvement and increased the likelihood of child protection services. Emergency or transitional housing and child protection involvement posed risks for lower school attendance and greater school mobility. CONCLUSIONS: A multisystem approach to assist families across social services may be important for stabilizing children's housing and bolstering their success at school. A two-generation approach focused on residential and school stability and enhancing family resources could boost adaptive success of family members across contexts.

Emotional reactivity and parenting in families experiencing homelessness.

Parents are key protective systems in the lives of children experiencing homelessness. Evidence suggests that parent emotional reactivity, expression, and regulation play a critical role in promoting adaptive parenting behaviors. Studies of emotional reactivity in parents utilize different methods, including self-report, observations, and physiological measures. However, these methods are rarely evaluated together, particularly among disadvantaged families. The present study examined how subjective (i.e., self-report), observed, and physiological measures of parent emotional reactivity relate to each other and to observed parenting behaviors in problem-solving and teaching parent-child interaction tasks. Participants included fifty 4- to 7-year-old children and their caregivers staying in an emergency homeless shelter. Observed and subjective emotional reactivity were largely uncorrelated, except for positive emotions during problem-solving tasks. Adaptive parenting behavior was related to lower scores on measures of subjective and observed negative emotions and higher observed scores for positive emotions during problem-solving tasks, as well as higher observed scores of positive emotions during teaching tasks. Physiological reactivity was not related to parenting behaviors. Results suggest that associations of emotional reactivity with parenting behavior depend on the context of the parent-child interaction and how emotional reactivity is measured.

Reliability of the BodyGuard2 (FirstBeat) in the Detection of Heart Rate Variability.

There has been an increasing interest in using cardiac indicators of self-regulation in developmental science. Many researchers are interested in unobtrusive mobile devises that are able to collect reliable cardiac data outside of the laboratory setting. Although numerous new ambulatory devices have become available over the last decade, testing these devices on children in comparison to industry gold-standard devices is rarely conducted. The current study evaluated the reliability of one of these ambulatory systems, the BodyGuard2 (FirstBeat), relative to gold-standard laboratory electrocardiogram (Biopac MP150), during active and resting conditions in 4- to 6-year-old children. The BodyGuard2 performed and produced highly similar indices of heart rate variability across resting and active conditions.

Self-regulation as promotive for academic achievement in young children across risk contexts.

The link between self-regulation and academic achievement in young children is well-documented. However, few studies have examined the extent to which different aspects of self-regulation are more important for early numeracy and literacy for those in contexts of high cumulative risk, such as children experiencing homelessness. In the current study, 116 children ages 4;0-7;1 years (58 residing in an emergency homeless shelter and 58 from a community participant pool) completed assessments of math and reading, as well as multiple measures of self-regulation: executive function (EF), emotion regulation (ER), and respiratory sinus arrhythmia (RSA). Parents completed a questionnaire about their children's behavioral regulation. We examined whether sample (i.e., shelter or community) moderated the association between each aspect of self-regulation and academic outcomes. Results showed a main effect of EF skills on early numeracy, and this relation did not differ across samples. Intervention efforts to promote academic competencies might specifically target EF in those who struggle with early EF skills regardless of risk context.

Parental Emotion Regulation Strategies and Parenting Quality Predict Child Internalizing Symptoms in Families Experiencing Homelessness.

Adaptive emotion regulation (ER) in parents has been linked to better parenting quality and social-emotional adjustment in children from middle-income families. In particular, early childhood may represent a sensitive period in which parenting behaviors and functioning have large effects on child social-emotional adjustment. However, little is known about how parent ER and parenting are related to child adjustment in high-risk families. In the context of adversity, parents may struggle to maintain positive parenting behaviors and adaptive self-regulation strategies which could jeopardize their children's adjustment. The current study investigated parents' own cognitive ER strategies and observed parenting quality in relation to young children's internalizing and externalizing problems among families experiencing homelessness. Participants included 108 primary caregivers and their four- to six-year-old children residing in emergency shelters. Using multiple methods, parenting and parent ER were assessed during a shelter stay and teachers subsequently provided ratings of children's internalizing and externalizing difficulties in the classroom. Parenting quality was expected to predict fewer classroom internalizing and externalizing behaviors as well as moderate the association between parent ER strategies and child outcomes. Results suggest that parenting quality buffered the effects of parent maladaptive ER strategies on child internalizing symptoms. The mediating role of parenting quality on that association was also investigated to build on prior empirical work in low-risk samples. Parenting quality did not show expected mediating effects. Findings suggest that parents experiencing homelessness who use fewer maladaptive cognitive ER strategies and more positive parenting behaviors may protect their children against internalizing problems.

Autonomic complexity and emotion (dys-)regulation in early childhood across high- and low-risk contexts.

Developing the ability to regulate one's emotions in accordance with contextual demands (i.e., emotion regulation) is a central developmental task of early childhood. These processes are supported by the engagement of the autonomic nervous system (ANS), a physiological hub of a vast network tasked with dynamically integrating real-time experiential inputs with internal motivational and goal states. To date, much of what is known about the ANS and emotion regulation has been based on measures of respiratory sinus arrhythmia, a cardiac indicator of parasympathetic activity. In the present study, we draw from dynamical systems models to introduce two nonlinear indices of cardiac complexity (fractality and sample entropy) as potential indicators of these broader ANS dynamics. Using data from a stratified sample of preschoolers living in high- (i.e., emergency homeless shelter) and low-risk contexts (N = 115), we show that, in conjunction with respiratory sinus arrhythmia, these nonlinear indices may help to clarify important differences in the behavioral manifestations of emotion regulation. In particular, our results suggest that cardiac complexity may be especially useful for discerning active, effortful emotion regulation from less effortful regulation and dysregulation.
