Early-life temperament: A longitudinal investigation of stability and structure

In this longitudinal study, we investigated the factor structure and stability of early-life temperament in a German sample, using three measures developed within Rothbart’s psychobiological approach. Temperament was measured using the Infant Behavior Questionnaire Revised (IBQ-R) at the ages of 6 and 12 months, the Early Childhood Behavior Questionnaire (ECBQ) at the age of 18 months, and the Child Behavior Questionnaire (CBQ) at the ages of 36 and 48 months. We assessed longitudinal stability on a scale and factor level using data from the 85 participants that took part in each measurement. The latent factor structures were analyzed at each time point using all available data, ranging from 112 to 148 participants. Modest to high degrees of stability for most scales and all three latent factors was found. Stability was highest between measurements employing the same instrument and increased with age, indicating a consolidation of temperament traits over time. Model fit for the proposed factor structure consisting of Surgency, Negative Affect, and Effortful Control/Regulatory Capacity was poor, while exploratory factor analyses revealed similar but not identical structures for each time point. The third factor of Regulatory Capacity was not found at 6 months, but at 12 months and later, as is commonly the case in German samples. These findings further contribute to our understanding of the early development of temperament and its stability from infancy and beyond as well as expand on previous literature regarding its structure in German culture.

The effectiveness of group play therapy using sand on social skills and behavioral problems of 5-9-year-old children in Tehran

This research was conducted with the aim of investigating the effectiveness of group play therapy using sand on children's social skills and behavioral problems. The statistical population included all children aged 5 to 9 years in Tehran in 1403, and among them 30 students were selected by available sampling according to the entry criteria and placed in two experimental and control groups. Then, at first, the subjects were measured by Babadi and Meshkani's life skills questionnaire (1389) and Shahim and Yousefi's children's behavioral problems questionnaire (1378) and after receiving group play therapy training using sand according to the protocol, the subjects again They completed the questionnaires. The research findings were analyzed by SPSS software using covariance analysis method and the results indicated the high effectiveness of group play therapy using sand on improving social skills and reducing children's behavioral problems

Measuring temperament in developmental research: A thin-slice approach to capturing temperament in infants and toddlers.

Temperament is a key factor in early development and predicts several key developmental outcomes. The ability to capture temperament in a variety of settings and ages is thus increasingly useful. Recent work has demonstrated the utility, reliability, and validity of thin-slice assessments in which brief snapshots of children's behavior are used to make inferences about general traits (Tackett et al., 2016). Thin-slice has been effective for assessing personality in older children (over 7-years; Tackett et al., 2016, 2017) and preschoolers 3-6 years old (Whalen et al., 2021) when engaging in lab tasks or clinical assessments. However, no work has examined the use of thin-slice for temperament in younger, typically developing infants/toddlers during lab-based tasks. The present study aims to test a downward extension of a modified thin-slice approach to assess temperament using archived videos of 516 infants/toddlers (nfemale = 255; Mage = 27.51 months, Rangeage = 17-47 months). Children were originally recruited from a range of socioeconomic backgrounds across the central United States and completed a short play session, which incorporated standard language and cognition tasks that were not designed to elicit temperament; caregivers also reported their children's temperament using the Early Child Behavior Questionnaire (Putnam & Rothbart, 2006). Naive raters scored the videos using a modification of the thin-slice approach. We find evidence of good reliability and validity for temperament scores using this approach suggesting thin-slice assessments are another method for measuring temperament in infants and toddlers. Moreover, thin-slice allows for post assessment of temperament even when it had not been formally assessed. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

How do fathers' educational level contribute to children's school problems? Overparenting and children's gender and surgency in a moderated mediation model.

This study aims to investigate (a) the mediating role of overparenting between father's educational level and children's school problems, and (b) the joint moderating role of children's gender and surgency in the indirect relationship between father's educational level and school problems. Participants were 203 school children, 96 boys (47.3%) and 107 girls (52.7%), aged 7-8 years (M = 92.42 months, SD = 3.52). Fathers reported their educational level, age and employment status and their children's gender and number of siblings, as well as their overparenting behaviors by Anticipatory Problem Solving (APS) scale. Teachers informed children's school problems by the Behavior Assessment System for Children (BASC T-2). Parents together informed their children's surgency levels by a subscale of Children's Behavior Questionnaire (CBQ). Results showed that, in girls, the father's educational level was negatively related to the child's school problems via overparenting behaviors, controlling the number of siblings and father's age and employment status. However, among boys, fathers' overparenting protect their shy sons from the risk of a low educational level for school problems. These findings highlight the relevance of considering the gender and surgency to a better understanding of the effects of contextual factors on children's outcomes.

INSIGHT responsive parenting intervention effects on child self-regulation at ages 3 and 6 years.

Self-regulation encompasses the ability to modulate behavior, cognition, and emotions. Parents can promote child self-regulation with responsive parenting (RP). RP shapes various components of self-regulation and is associated with numerous developmental outcomes. Here, we examine long-term effects of an early-life RP intervention designed for obesity prevention on later child self-regulation and temperament. Participants were from a randomized clinical trial comparing the RP intervention against a safety control (n = 279). RP intervention content in the domains of feeding, sleep, emotion regulation, and interactive play was delivered to primiparous mothers and infants at four home visits during the first year after birth, followed by clinical research center visits at ages 1 and 2 years and phone calls at 1.5 and 2.5 years. Child self-regulation and temperament were assessed with behavioral tasks and the Children's Behavior Questionnaire at child ages 3 and 6 years. A path model tested whether the RP intervention affected child self-regulation in comparison to the control group. At 6 years, children in the RP group had lower parent-reported negative affect (b = -0.34, SE = 0.15, p = .023) and better observed emotion regulation (b = 0.45, SE = 0.16, p = .007). Findings indicate that an RP intervention designed for early obesity prevention promoted emotional aspects of self-regulation in middle childhood, highlighting RP as a strategy for promoting healthy behavior across multiple domains.

Parental Perception of Vulnerability, Child’s Temperament, and Health Locus of Control: Who Made You Boo-Boo?

Background: In Pakistan, where unintentional injuries among toddlers pose a significant public health challenge, understanding the factors that contribute to elevated injury risks is crucial. A two-dimensional approach including parental factors (internal/external health locus of control and perceived vulnerability) and child factors (the child’s temperament) is explored as contributing to the unintentional injury behaviors of toddlers. Method: The study involved 241 parents of toddlers aged 18–36 months from daycare centers in three major Pakistani cities who had observed multiple recent injuries in their children. The comprehensive online assessment, lasting 15–20 minutes, incorporated the child vulnerability scale, injury behavior checklist, parent health locus of control questionnaire, and early childhood behavior questionnaire. Demographic details included child and parent age distributions, with a focus on educational backgrounds. The participants comprised both fathers and mothers, and the data analysis employed Smart-PLS software for structural equation modeling. Result: The results suggested there is no direct relationship between parental health locus of control (internal/external) and injury behaviors in children. However, an indirect and significant path was observed from the parental health locus of control (internal/external) to perceived child vulnerability and injury behaviors through moderation of temperamental characteristics. Conclusion: Our research underscores the indirect link between parental factors, child temperament, and toddler injuries in Pakistan. Culturally sensitive interventions targeting parental awareness can play a pivotal role in safeguarding the well-being of the youngest members of society.

Early childhood executive control modulates negative affectivity's role in increasing adolescent body mass index trajectories.

Executive control and temperament have been associated with pediatric obesity. However, interactions between these constructs in relation to future weight outcomes have not been investigated. This longitudinal study examined early childhood executive control, early temperament (negative affectivity and surgency), and their interactions as predictors of adolescent BMI trajectories. At age 5.25, children (N = 229) completed executive control tasks, and parents completed the Child Behavior Questionnaire to assess temperament. BMI was calculated annually between ages 14-17. Greater early negative affectivity predicted more positive BMI growth. Although early childhood executive control was not associated with BMI growth, greater negative affectivity predicted greater BMI escalation at average and below average executive control abilities. For children without robust executive control abilities early in development, negative affectivity may be a risk factor for accelerated adolescent BMI growth. Targeted assessment of early risk factors may be useful for childhood obesity prevention efforts.

Early-Childhood Tablet Use and Outbursts of Anger

Tablet use continues to increase in preschool-aged children. The use of mobile devices has been linked to child emotional dysregulation. However, few studies have been able to show a clear direction of association between child tablet use and the development of self-regulation skills. In addition, few studies have modeled within-person associations over time. To estimate how child tablet use contributes to expressions of anger and frustration across the ages of 3.5 to 5.5 years at the within-person level. The study team also examined the extent to which associations are bidirectional to clarify the direction of the correlations. This prospective, community-based convenience sample of 315 parents of preschool-aged children from Nova Scotia, Canada, was studied repeatedly at the ages of 3.5 (2020), 4.5 (2021), and 5.5 years (2022) during the COVID-19 pandemic. All analyses were conducted between October 5, 2023, and December 15, 2023. Parent-reported tablet use at the ages of 3.5, 4.5, and 5.5 years. Parents reported child expressions of anger/frustration at the ages of 3.5, 4.5, and 5.5 years using the Children's Behavior Questionnaire. The sample was equally distributed across child sex (171 were identified by parents as being born boys [54%] and 144 as girls [46%]). Most reported being Canadian (287 [91.0%]) and married (258 [82.0%]). A random-intercept cross-lagged panel model revealed that a 1-SD increase in tablet use at 3.5 years (corresponding to 1.22 hours per day) was associated with a 22% SD scale increase in anger/frustration at age 4.5 years (standardized coefficient = 0.22; 95% CI, 0.01-0.44). A 1 SD scale increase in anger and frustration at 4.5 years was associated with a 22% SD (corresponding to 0.28 hours per day) increase in tablet use at 5.5 years (standardized coefficient = 0.22; 95% CI, 0.01-0.43). In this study, child tablet use at age 3.5 years was associated with more expressions of anger and frustration by the age of 4.5 years. Child proneness to anger/frustration at age 4.5 years was then associated with more use of tablets by age 5.5 years. These results suggest that early-childhood tablet use may contribute to a cycle that is deleterious for emotional regulation.

Large-scale proteomics in the first trimester of pregnancy predict psychopathology and temperament in preschool children: an exploratory study.

Understanding the prenatal origins of children's psychopathology is a fundamental goal in developmental and clinical science. Recent research suggests that inflammation during pregnancy can trigger a cascade of fetal programming changes that contribute to vulnerability for the emergence of psychopathology. Most studies, however, have focused on a handful of proinflammatory cytokines and have not explored a range of prenatal biological pathways that may be involved in increasing postnatal risk for emotional and behavioral difficulties. Using extreme gradient boosted machine learning models, we explored large-scale proteomics, considering over 1,000 proteins from first trimester blood samples, to predict behavior in early childhood. Mothers reported on their 3- to 5-year-old children's (N = 89, 51% female) temperament (Child Behavior Questionnaire) and psychopathology (Child Behavior Checklist). We found that machine learning models of prenatal proteomics predict 5%-10% of the variance in children's sadness, perceptual sensitivity, attention problems, and emotional reactivity. Enrichment analyses identified immune function, nervous system development, and cell signaling pathways as being particularly important in predicting children's outcomes. Our findings, though exploratory, suggest processes in early pregnancy that are related to functioning in early childhood. Predictive features included far more proteins than have been considered in prior work. Specifically, proteins implicated in inflammation, in the development of the central nervous system, and in key cell-signaling pathways were enriched in relation to child temperament and psychopathology measures.

Maternal Phubbing and Problematic Media Use in Preschoolers: The Independent and Interactive Moderating Role of Children's Negative Affectivity and Effortful Control.

Given that mother plays the main nurturing role in a family unit and their unique influence on children's development, the current study aimed to examine the influence of maternal phubbing on children's problematic media use and the independent and interactive moderating role of children's negative affectivity and effortful control. Participants were 1986 children aged 3 to 6 years in Shanghai, China. Their mothers were asked to complete a series of questionnaires including parental phubbing scale, problematic media use measure, and child behavior questionnaire. To investigate the moderating influence of children's negative affectivity and effortful control, hierarchical linear regression analyses were conducted using SPSS 24.0. Simple slopes analyses and the Johnson-Neyman technique were further used to depict moderation effects. Maternal phubbing was associated with higher levels of problematic media use in preschool children (β = 0.18, p <.001, [0.14, 0.22]). Children's negative affectivity acts as a risk factor, exacerbating the adverse effects of maternal phubbing on children's problematic media use (β = 0.05, t = 2.69, p < 0.05), whereas children's effortful control acts as a protective factor, buffering the link between maternal phubbing and children's problematic media use (β = -0.10, t = -5.00, p < 0.001). These results suggest that interventions seeking to promote appropriate digital development in preschoolers should take the child's temperament into account and be complemented by active parental mediation and involvement.

Effects of a staff physical activity professional development intervention on preschoolers' mental health and self-regulation: The active learning Norwegian Preschool(er)s (ACTNOW) cluster randomised controlled trial

Background and aimPhysical activity may have positive effects on preschoolers' mental health and self-regulation. The preschool setting provides children with opportunities to meet physical activity guidelines and could improve with staff training in delivering physical activity. This study examined the effect of physical activity professional development for preschool staff on preschoolers' proxy-measured mental health and self-regulation. MethodsIn total, 1265 children from 46 preschools were cluster randomised to either the intervention or the control group. The intervention was nested within two levels implemented concurrently: the preschool level, formed as a professional development where preschools conducted development work, and the child level, with whom the staff implemented physical activity with four core components. Data were analysed using an ANCOVA model through structural equation modelling with latent outcome factors of: emotional problems, peer problems, hyperactivity, and prosocial behaviour from the Strength and Difficulties Questionnaire; and cognitive, emotional, and behavioural self-regulation from the Child Self-regulation and Behaviour Questionnaire. ResultsNo effects of the intervention (standardised effect sizes -0.195–0.145, p-values 0.118–0.893) were observed. Secondary analysis showed that children with initially high prosocial behaviour and behavioural self-regulation positively benefited from the intervention (p = 0.035 and p = 0.047, respectively). ConclusionThe ACTNOW intervention had no effects on preschoolers' mental health or self-regulation after 18 months, besides effects for children with initially the highest prosocial behaviour and behavioural self-regulation. Although the professional development was more extensive than previous studies it may have been insufficient to change the preschools physical activity practices.

Cure for tantrums? Longitudinal associations between parental digital emotion regulation and children's self-regulatory skills

IntroductionParents often use digital devices to regulate their children's negative emotions, e.g., to stop tantrums. However, this could hinder child development of self-regulatory skills. The objective of the study was to observe bidirectional longitudinal associations between parents' reliance on digital devices to regulate their child's emotions and self-regulatory tendencies (anger/frustration management, effortful control, impulsivity).MethodsParents (N = 265) filled out the Child Behavior Questionnaire—Short Form and the Media Assessment Questionnaire twice: the initial assessment (T1) took place in 2020 (mean child age = 3.5 years old), and follow-up (T2) occurred a year later in 2021 (mean child age = 4.5 years old).ResultsHigher occurrence of parental digital emotion regulation (PDER) in T1 predicts higher anger and lower effortful control in T2, but not impulsivity. Higher anger in T1, but not impulsivity and effortful control, predicts higher PDER in T2.DiscussionOur results suggest that parents of children with greater temperament-based anger use digital devices to regulate the child's emotions (e.g., anger). However, this strategy hinders development of self-regulatory skills, leading to poorer effortful control and anger management in the child.

Early Life Surgency, but not Effortful Control or Negative Affectivity, Is a Mediating Variable Between Maternal Pre-Pregnancy Body Mass Index and Childhood Obesity Risk.

Maternal gestational obesity is related to risk of obesity in the child. This risk may be in part mediated by altered child temperament, which can affect mother-child interactions, including feeding and soothing behaviors that affect obesity risk. Our objective was to examine the association between maternal pre-pregnancy BMI and child zBMI and determine if child temperament, specifically positive Affectivity/Surgency, mediates this association. Using conditional process modeling, we analyzed data from 408 mother-child dyads enrolled in the Alberta Pregnancy Outcomes and Nutrition (APrON) study. Child temperament was assessed at 3 years of age via a parent report measure, the Child Behavior Questionnaire (CBQ), and child zBMI was calculated from in-person measurements of child height and weight at 4-5 years of age. Bivariate correlations showed that there was a significant positive correlation between zBMI and Surgency (r=0.11, p=0.03), and zBMI was also correlated with maternal pre-pregnancy BMI (r=0.12, p=0.02). Multivariable regression revealed that maternal pre-pregnancy BMI (adjusted β=0.15, 95% confidence interval [CI]; 0.00-0.05, p=0.02) and Surgency scores (adjusted β=0.14, 95% CI; 0.02-0.28, p=0.03) were associated with higher child zBMI at 4-5 years of age. Mediation analysis showed that Surgency mediated the association between pre-pregnancy BMI and child zBMI. Our models controlled for maternal gestational weight gain, gestational diabetes, socioeconomic status, maternal anxiety and depression, and gestational age at birth. Overall, maternal pre-pregnancy BMI was positively associated with child zBMI, and this association was mediated by higher child Surgency scores.

Maternal lifetime stress and psychological functioning in pregnancy is associated with preschoolers' temperament: Exploring effect modification by race and ethnicity

BackgroundPsychosocial stress and psychopathology frequently co-occur, with patterns differing by race and ethnicity. We used statistical mixtures methodology to examine associations between prenatal stress and child temperament in N = 382 racially and ethnically diverse maternal-child dyads to disentangle associations among maternal stressful life events, maternal psychological functioning in pregnancy, childhood neurobehavior, and maternal race and ethnicity. MethodsThis study utilized data from a longitudinal pregnancy cohort, PRogramming of Intergenerational Stress Mechanisms (PRISM). Mothers completed the Lifetime Stressor Checklist-Revised, Edinburgh Postnatal Depression Scale, and Spielberger State-Trait Anxiety Scale during pregnancy. When their children were 3–5 years of age, they completed the Children's Behavior Questionnaire, which yields three temperament dimensions: Negative Affectivity (NA), Effortful Control (EC), and Surgency (S). We used weighted quantile sum regression to derive a weighted maternal stress index encompassing lifetime stress and depression and anxiety symptoms and examined associations between the resulting stress index and child temperament. Differential contributions of individual stress domains by race and ethnicity also were examined. ResultsMothers self-identified as Black/Black Hispanic (46.1 %), non-Black Hispanic (31.9 %), or non-Hispanic White (22 %). A higher maternal stress index was significantly associated with increased child NA (β = 0.72 95 % CI = 0.35, 1.10). Lifetime stress was the strongest contributor among Hispanic (36.7 %) and White (17.8 %) mothers, whereas depressive symptoms in pregnancy was the strongest contributor among Black (16.7 %) mothers. ConclusionPrenatal stress was most strongly associated with negative affectivity in early childhood. Consideration of multiple stress measures as a mixture accounted for differential contributions of individual stress domains by maternal race and ethnicity. These findings may help elucidate the etiology of racial/ethnic disparities in childhood neurobehavior.

Social Perception in the Infant Brain and Its Link to Social Behavior.

The current longitudinal study (n = 98) utilized a developmental cognitive neuroscience approach to examine whether and how variability in social perception is linked to social behavior in early human development. Cortical responses to processing dynamic faces were investigated using functional near-infrared spectroscopy at 7 months. Individual differences in sociability were measured using the Early Childhood Behavior Questionnaire at 18 months. Confirming previous work with infants and adults, functional near-infrared spectroscopy results show that viewing changing faces recruited superior temporal cortices in 7-month-old infants, adding to the view that this brain system is specialized in social perception from early in ontogeny. Our longitudinal results show that greater engagement of the right superior temporal cortex at 7 months predicts higher levels of sociability at 18 months. This suggests that early variability in social perception is linked to later differences in overtly displayed social behavior, providing novel longitudinal evidence for a social brain-behavior association.

Dorso-medial prefrontal cortex responses to social smiles predict sociability in early human development

Abstract Dorso-medial prefrontal cortex (dmPFC) plays a vital role in social cognition and behavior among humans. Enhanced responses in dmPFC when viewing social scenes predict increased levels of sociability in adults. The current longitudinal study examined the association between dmPFC response and sociability in early development. Brain responses were measured in response to social smiles and frowns using functional near-infrared spectroscopy (fNIRS) at 11 months. Individual differences in sociability were measured using the Early Childhood Behavior Questionnaire (ECBQ) at 18 months. Our longitudinal results show that greater engagement of the dmPFC when processing social smiles, but not frowns, at 11 months predicts higher levels of sociability at 18 months. This demonstrates that early variability in dmPFC response during positive social interactions is linked to individual differences in overtly displayed social behavior. This supports the view that dmPFC plays an important role in social cognition and behavior from early in human ontogeny.

Coparenting as a family-level construct: Parent and child inputs across the first two years.

This study examined the effects of infant negative affectivity (NA) and maternal and paternal depressive symptoms on fathers' and mothers' perceptions of coparenting across the first 2 years following an infant's birth. A total of 147 two-parent families (most couples were White, married, and living together) with healthy, full-term infants were recruited. At each time point, fathers and mothers separately reported their coparenting perceptions via the Coparenting Relationship Scale and their depressive symptoms using the depression subscale of Symptom Checklist-90-Revised. Mothers also reported their children's NA via the Infant Behavior Questionnaire-Revised at 3 to 12 months and the Early Child Behavior Questionnaire at 18 and 24 months. Findings from growth curve models in an actor-partner interdependence model framework suggested that among parents with higher depression, there were steeper declines in coparenting quality reported by parents and their spouses across 3-24 months. In addition, three separate two-way interactions between variables including higher-than-usual parental and spousal depression, as well as higher-than-usual infant NA predicted poorer-than-usual coparenting experiences. Findings indicate that coparenting is a dynamically unfolding construct that is impacted by ongoing changes in the parents' social-ecological niche and suggest the need to consider both parent and child characteristics, and to include spousal influences, to get a comprehensive, whole-family understanding of levels and changes in coparenting relationships. The findings also confirm that coparenting dynamics may benefit from interventions engaging both couples and addressing multiple risk factors from both parents (e.g., depression) and children (e.g., NA).

Effectiveness of cognitive-behavioral group play therapy on anxiety-based school refusal and behavioral problems in elementary school boys: a preliminary randomized controlled trial

This study aimed to examine the effectiveness of cognitive-behavioral group play therapy on anxiety-based school refusal and behavioral issues in elementary school boys. A randomized controlled trial design (pretest-posttest with a control group) was utilized. Thirty elementary school boys with school refusal issues were randomly assigned to intervention (n = 15) and control (n = 15) groups. The intervention group received ten sessions of cognitive-behavioral group play therapy. The Screen for Child Anxiety-Related Emotional Disorders (SCARED) questionnaire and Rutter's Children's Behavior Questionnaire were used as assessment tools. Mean scores for anxiety-based school refusal and behavioral problems in the intervention group showed a significant decrease (p < 0.001). Cognitive-behavioral group play therapy is a practical approach to reducing anxiety levels and behavior problems in children with anxiety-based school refusal in primary school grades.

Teachers’ Perspectives on Behavioral and Emotional Problems among School-going Adolescents in Kashmir: Examining the Risk Correlates of Behavioral and Emotional Problems

ABSTRACT Background: Political violence in Kashmir was a common occurrence. The phenomenon had occurred often and repeatedly in an unmanageable fashion. It had consequential implications for each member of society including children and adolescents. Aim: The study aimed to analyze the teachers’ perspective on mental health problems of adolescents in Kashmir. In Kashmir’s precarious circumstances, school-going adolescents were exceptionally vulnerable to mental health issues. Addressing unrecognized mental health issues among school-going adolescents established an important rationale for corresponding further deterioration. Methods: The study used the standardized tools of the Rutter’s Children Behavior Questionnaire (RCBQ-B) and the Strengths and Difficulties Questionnaire (SDQ). Cluster sampling was employed in the study. About 45 schoolteachers rated the behaviors of 160 school-going adolescents of Kashmir from numerous schools. The data were statistically analyzed using descriptive and inferential statistics such as t-test and one-way analysis of variance and correlation. Results: We found that behavioral and emotional problems (BEPs) rose significantly, most notably indications of BEPs with risk factors. Across the socioeconomic status, age, adolescence type, and education, the results found an upward trend of 47% prevalence rate of mental health problems among adolescents with 45% as peer problems, 39% hyperactivity, 34% conduct, and 9% emotional problems. Conclusion: An increasing number of adolescents in prevailing situations in Kashmir suffered from mental health problems. The study findings reveal that there is a need to create effective mental health services and interventions for school-going adolescents in Kashmir.
