Negative Affectivity Moderates Associations between Cumulative Risk and At-Risk Toddlers' Behavior Problems

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

Purpose

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.

Methods

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.

Results

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).

Conclusion

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.

Longitudinal Study of Early Adversity and Disturbing Dream Frequency: Moderating Role of Early Negative Emotionality

Although disturbing dreams are prevalent in youth and are associated with psychopathology, little is known about their developmental course and risk factors. We aimed to examine the association between early social environment and subsequent disturbing dream frequency across adolescence as moderated by early negative emotionality. Measures of children's early social environment and negative emotionality were collected from the mothers of 410 children (5-42 months old) and measures of disturbing dream frequency directly from the children (13-18 years old). Preliminary steps identified subgroups of families with distinct profiles of social environment using latent variable mixture modeling, and captured changes in disturbing dream frequency using latent growth modeling. Regression and moderation analyses were conducted to test the study objectives. Results showed that the diverse family patterns were best captured by two profiles reflecting adverse and positive social environments and that overall disturbing dream frequency decreased during adolescence. Moderation analyses showed that when early negative emotionality was higher, DD frequency was not only more elevated in an adverse environment, but lower in a positive environment. These results indicate that the development of disturbing dreams is most strongly associated with a combination of individual and environment factors. Our study adds to the literature by refining our conception of individual traits and disturbing dream development and has implications for the prevention of bad dreams, nightmares, and associated psychopathologies.

The bidirectional relationship between head injuries and conduct problems: longitudinal modelling of a population-based birth cohort study

Childhood head injuries and conduct problems increase the risk of aggression and criminality and are well-known correlates. However, the direction and timing of their association and the role of their demographic risk factors remain unclear. This study investigates the bidirectional links between both from 3 to 17 years while revealing common and unique demographic risks. A total of 8,603 participants (50.2% female; 83% White ethnicity) from the Millennium Cohort Study were analysed at 6 timepoints from age 3 to 17. Conduct problems were parent-reported for ages 3 to 17 using the Strengths and Difficulties Questionnaire (SDQ) and head injuries at ages 3 to 14. A cross-lagged path model estimated the longitudinal bidirectional effects between the two whilst salient demographic risks were modelled cumulatively at three ecological levels (child, mother, and household). Conduct problems at age 5 promoted head injuries between 5 and 7 (Z = 0.07; SE = 0.03; 95% CI, 0.02-0.13), and head injuries at ages 7 to 11 promoted conduct problems at age 14 (ß = .0.06; SE = .0.03; 95% CI, 0.01-0.12). Head injuries were associated with direct child-level risk at age 3, whereas conduct problems were associated with direct risks from all ecological levels until 17 years. The findings suggest a sensitive period at 5-11 years for the bidirectional relationship shared between head injuries and conduct problems. They suggest that demographic risks for increased head injuries play an earlier role than they do for conduct problems. Both findings have implications for intervention timing.

Linked head injury and conduct problem symptom pathways from early childhood to adolescence and their associated risks: Evidence from the millennium cohort study

Conduct problems and head injuries increase the risk of delinquency and share a bidirectional association. However, how they link across development is unknown. The present study aimed to identify their linked developmental pathways and associated risk factors. Latent class analysis was modeled from Millennium Cohort Study data (n = 8,600) to identify linked pathways of conduct problem symptoms and head injuries. Head injuries were parent-reported from ages 3 to 14 and conduct problems from ages 3 to 17 using the Strengths and Difficulties Questionnaire (SDQ). Multinomial logistic regression then identified various risk factors associated with pathway membership. Four distinct pathways were identified. Most participants displayed low-level conduct problem symptoms and head injuries (n = 6,422; 74.7%). Three groups were characterized by clinically relevant levels of conduct problem symptoms and high-risk head injuries in childhood (n = 1,422; 16.5%), adolescence (n = 567; 6.6%), or persistent across development (n = 189; 2.2%). These clinically relevant pathways were associated with negative maternal parenting styles. These findings demonstrate how pathways of conduct problem symptoms are uniquely linked with distinct head injury pathways. Suggestions for general preventative intervention targets include early maternal negative parenting styles. Pathway-specific interventions are also required targeting cumulative risk at different ecological levels.

Perinatal Physiological and Psychological Risk Factors and Childhood Sleep Outcomes: A Systematic Review and Meta-analysis

OBJECTIVES

The purpose of this study was to investigate the influence of maternal physiological and psychological factors during pregnancy and after birth on infant and children's sleep outcomes.

METHODS

Six databases were searched from inception to April 2021. Longitudinal studies that investigated the association of risk factors during and after pregnancy and children's sleep-related outcomes were included. Hedge's g and odds ratio were pooled as effect size with random effects model.

RESULTS

A total of 32 articles were included. Both prenatal maternal alcohol use (odds ratio [OR] = 1.85, 95% confidence interval [CI]: 1.04-3.28) and tobacco smoking (OR = 1.28, 95% CI: 1.01-1.62) were associated with shorter child sleep duration. Prenatal and postnatal maternal depression symptoms were associated with increased child sleep problems at age 6 months (OR = 1.97, 95% CI: 1.19-3.24, and 2.05, 95% CI: 1.37-3.07, respectively). Prenatal and postnatal maternal major depression disorders were associated with shorter sleep duration (Hedge's g = -0.97, 95% CI: -1.57 to -0.37) and lower sleep efficiency (Hedge's g = -1.44, 95% CI: -1.93 to -0.95). Prenatal anxiety had no impact on child sleep problems (OR = 1.34, 95% CI: 0.86-2.10).

CONCLUSION

Maternal pregnancy and obstetric factors and psychological factors are potential risk factors of poor child sleep health. Future research is warranted to better understand the impact of these risk factors on long-term child sleep outcomes and their potential mediating mechanisms.

Associations between cumulative risk, childhood sleep duration, and body mass index across childhood

BACKGROUND

Although associations between cumulative risk, sleep, and overweight/obesity have been demonstrated, few studies have examined relationships between these constructs longitudinally across childhood. This study investigated how cumulative risk and sleep duration are related to current and later child overweight/obesity in families across the United States sampled for high sociodemographic risk.

METHODS

We conducted secondary analyses on 3690 families with recorded child height and weight within the Fragile Families and Child Well-Being Study. A cumulative risk composite (using nine variables indicating household/environmental, family, and sociodemographic risk) was calculated for each participant from ages 3-9 years. Path analyses were used to investigate associations between cumulative risk, parent-reported child sleep duration, and z-scored child body mass index (BMI) percentile at ages 3 through 9.

RESULTS

Higher cumulative risk experienced at age 5 was associated with shorter sleep duration at year 9, b = - 0.35, p = .01, 95% CI [- 0.57, - 0.11]. At 5 years, longer sleep duration was associated with lower BMI, b = - 0.03, p = .03, 95% CI [- 0.06, - 0.01]. Higher cumulative risk at 9 years, b = - 0.34, p = .02, 95% CI [- 0.57, - 0.10], was concurrently associated with shorter sleep duration. Findings additionally differed by child sex, such that only male children showed an association between sleep duration and BMI.

CONCLUSIONS

Results partially supported hypothesized associations between child sleep duration, cumulative risk, and BMI emerging across childhood within a large, primarily low socioeconomic status sample. Findings suggest that reducing cumulative risk for families experiencing low income may support longer child sleep duration. Additionally, child sleep duration and BMI are concurrently related in early childhood for male children.

Early life stress and behavior problems in early childhood: Investigating the contributions of child temperament and executive functions to resilience

This preregistered study examined whether child temperament and executive functions moderated the longitudinal association between early life stress (ELS) and behavior problems. In a Dutch population-based cohort (n = 2803), parents reported on multiple stressors (age 0-6 years), child temperament (age 5), and executive functions (age 4), and teachers rated child internalizing and externalizing problems (age 7). Results showed that greater ELS was related to higher levels of internalizing and externalizing problems, with betas reflecting small effects. Lower surgency buffered the positive association of ELS with externalizing problems, while better shifting capacities weakened the positive association between ELS and internalizing problems. Other child characteristics did not act as moderators. Findings underscore the importance of examining multiple protective factors simultaneously.

Negative affectivity moderated by preterm birth predicted toddlers' behavior problems

OBJECTIVE

The present study aimed to examine the predictive effect of temperament moderated by preterm childbirth on behavioral problems in toddlerhood.

METHOD

The sample comprised 100 toddlers of 18-36 months of chronological age and their mothers. They were divided into two groups: 50 toddlers born preterm and admitted to the Neonatal Intensive Care Unit (PT group), and 50 toddlers born full-term (FT group) and recruited from day-care centers. Mothers completed questionnaires about toddlers' temperament and behavior. The Early Childhood Behavior Questionnaire was used to assess temperament, and the Child Behavior Checklist (CBCL 1¹/²-5) to evaluate the total, internalizing, and externalizing behavior problems. Multiple regression analysis was performed to examine the moderation effects of preterm childbirth and temperament factors after controlling for toddlers' age and socioeconomic level.

RESULTS

There was a moderation effect between preterm childbirth and temperament. Temperament with more Negative Affectivity, moderated by preterm birth, and less Effortful Control explained the total, internalizing, and externalizing behavior problems.

CONCLUSION

The findings contribute to a better understanding of the impact of preterm childbirth and the dispositional traits of temperament on behavioral problems of toddlers born preterm.

Persistent Short Sleep from Childhood to Adolescence: Child, Parent and Peer Predictors

PURPOSE

Many children have periods when they sleep too little, with widely recognized detrimental effects. Less is known about persistent short sleep during childhood. Therefore, the present study aimed to investigate the prevalence of persistent short sleep in school-aged children and identify a set of child, parent, and peer predictors thereof.

PARTICIPANTS AND METHODS

Objectively measured sleep duration (hip-held accelerometer) was biennially assessed in a community sample followed from 6 to 14 years (n=801). A latent profile analysis was applied to assess whether a subgroup of children slept consistently short across time and predictors of persistent short sleep were determined through regression analysis.

RESULTS

A subgroup of children (n=160; 20.2%) was identified as having persistent short sleep across time. Temperamental negative affectivity (β=0.08; 95% CI=0.01, 0.15; p=0.03) and low observer-assessed parental emotional availability (β=-.09; 95% CI=-.18, -.01; p=0.04) predicted membership to that group. Teacher ratings of victimization from bullying were not associated with persistent short sleep (β=0.01; 95% CI: -.10, 11; p=0.88).

CONCLUSION

High child temperamental negative affectivity and low parental emotional availability may be involved in the development of persistent short sleep through childhood.

Disturbing Dreams and Psychosocial Maladjustment in Children: A Prospective Study of the Moderating Role of Early Negative Emotionality

Although frequent disturbing dreams, including bad dreams and nightmares, have been repeatedly associated with poor psychological well-being in adults, considerably less information exists on their psychosocial correlates in children. Recent empirical and theoretical contributions suggest that the association between disturbing dream frequency and psychosocial adaptation in children may differ as a function of children's negative emotionality. The current study assessed the moderating effect of very early negative emotionality (17 months of age) in the relation between disturbing dream frequency and psychosocial maladjustment (i.e., externalizing + internalizing behaviors) in a sample of 173 11-year-old children. Mixed-model analyses revealed that disturbing dream frequency was associated with some internalizing behaviors but that the association between disturbing dream frequency and most externalizing behaviors was moderated by early negative emotionality. The latter result indicates that the relation between disturbing dream frequency and externalizing behaviors was significant in 11-year-old children showing moderate negative emotionality early in life, but particularly strong in those children with high early negative emotionality. Whereas, a moderating effect of early negative emotionality was not found between disturbing dream frequency and internalizing behaviors, the findings highlight the more specific role of early emotional negativity as a developmental moderator for the link between disturbing dreams and externalizing behaviors in children. The results are discussed in light of recent models of disturbed dreaming production.

Prenatal risk and physical aggression during the first years of life: The gender-specific role of inhibitory control

Prenatal risk and a lack of inhibitory control have consistently been related to the development of physical aggression in older children. This study examined whether inhibitory control mediated the relation between prenatal risk and aggression in infants and toddlers. The role of gender in this mediation model was also examined. The sample consisted of 161 mother-child dyads (83 boys). A prenatal cumulative risk score was created from a number of well-established risk factors including maternal psychopathology, substance use, and social and socioeconomic disadvantages. At 12 months, children performed an inhibitory control task. Physical aggression was assessed through maternal reports at 12 and 20 months of age. Results showed that higher prenatal risk was associated with more physical aggression. Inhibitory control mediated this association at both 12 and 20 months: higher prenatal risk was related to lower inhibitory control, which in turn led to higher aggression. At 20 months, gender moderated the mediation effect: the mediating role of inhibitory control was only found for girls. These results suggest that even before 2 years of age, inhibitory control is an important construct involved in the relation between prenatal risk and physical aggression.

Aggressive behavior during toddlerhood: Interrelated effects of prenatal risk factors, negative affect, and cognition

Prenatal risk, temperamental negative affect, and specific cognitive abilities have all individually been identified as predictors of behavior problems during early childhood, but less is known about their interplay in relation to aggression during toddlerhood. This study examined the main and interaction effects of prenatal risk, negative affect, inhibitory control, attention, and vocabulary in the prediction of aggression in 150 children (75 boys). During pregnancy, a cumulative risk index was calculated based on the presence of 10 well-established maternal risk factors, such as prenatal substance use, maternal psychiatric disorder, and financial problems. Negative affect was measured at 6 and 20 months using maternal report. Child cognition was examined at 30 months using laboratory tasks for inhibitory control and attention, and a questionnaire was administered to assess vocabulary. In addition, mothers reported on their children's aggressive behavior at 30 months. Higher prenatal risk and negative affect at 20 months and, to a lesser extent, at 6 months were related to more aggression at 30 months. Poorer inhibitory control and, to a lesser extent, vocabulary at 30 months also predicted higher levels of aggressive behavior. Two-way interaction effects were found for cumulative risk and inhibitory control, negative affect (at 20 months) and inhibitory control, and negative affect (at 6 months) and vocabulary: aggressive behavior was most pronounced when combinations of high prenatal risk, high negative affect, and poor cognition were present. These results suggest that the impact of prenatal risk and child temperament depends in part on child's cognitive development during toddlerhood.

A Pragmatic Internet Intervention to Promote Positive Parenting and School Readiness in Early Childhood: Initial Evidence of Program Use and Satisfaction

BACKGROUND

Internet-based parenting programs have the potential to connect families to research-informed materials to promote positive child development. However, such programs can only succeed to the extent that the intended population engages with them.

OBJECTIVE

This study aimed to evaluate engagement in the 5-a-Day Parenting program, a technology-based program designed with low-income families in mind, to promote daily use of 5 specific parenting activities conducive to children's school readiness. Following earlier pilot data, the program was enhanced with an initial motivational e-intervention and tailored text messages designed to promote engagement.

METHODS

Parents were recruited from local childcare centers and through a participant registry. We examined rates of receipt of program text messages and use of video-based content on the program website, 3 factors that may affect website use, and satisfaction with key program elements.

RESULTS

A total of 360 parents of young children learned about the study and had the opportunity to use the 5-a-Day Parenting website. Of these, 94 parents participated in the study, and 33% (31/94) accessed the video-based content on the website at least once. No association was found between website use and program recruitment approach, program-affiliation message, sociocontextual risk, and baseline use of the five parenting activities. Satisfaction with text messages and video-based content was high.

CONCLUSIONS

For some parents, technology-based programs appear useful; however, engagement could still be enhanced. Additional research should seek innovative strategies for promoting engagement in Web-based parenting programs.

Toddler risk and protective characteristics: Common and unique genetic and environmental influences

The goal of this study was to disentangle the common and unique genetic and environmental influences on social-emotional competence, problem behavior, physiological dysregulation, and negative emotionality (NE) in toddlers. The sample consisted of 243 twin pairs (mean age = 31.94 months) rated by primary caregivers (>95% mothers) on the Children's Behavior Questionnaire and the Infant-Toddler Social and Emotional Assessment. A multivariate Cholesky Decomposition revealed three shared environmental factors, with one set of environmental influences common to competence, problem behavior, and physiological dysregulation, a second common to problem behavior and physiological dysregulation, and a third common to physiological dysregulation and NE. Also, there were two additive genetic factors, with one explaining variance in competence, NE, and a small amount of variance in problem behavior, and a second explaining variance in problem behavior and NE. Given the common shared environmental factors across outcomes, these results suggest that toddlerhood could be a particularly important time to intervene, as interventions could simultaneously improve competencies and reduce problem behaviors. This study also highlights the need for genetically informed research to examine the etiology of multiple outcomes and address overlap.

Interaction between maternal and paternal parenting styles with infant temperament in emerging behavior problems

This study examined the interaction effects of infant temperament (negative affect, orienting/regulatory capacity, surgency) on the relationship between maternal and paternal parenting styles (authoritative, authoritarian, permissive) and externalizing and internalizing behaviors simultaneously. A diverse sample of mothers (N = 186) and fathers (N = 142) reported on infant temperament of their 6-month-olds and their children's internalizing and externalizing behaviors one year later. Significant interactions revealed: (a) surgency moderated maternal authoritative and paternal permissive parenting style and externalizing behaviors; and (b) surgency moderated maternal authoritarian and paternal authoritative parenting style and internalizing behaviors. No significant interactions were found between maternal and paternal parenting styles and their report of their infants' orienting/regulatory capacity and negative affect. Findings suggest interaction effects may appear beginning in infancy.

The impact of maternal stress on infant alpha-amylase is buffered by high infant regulation and low infant negative reactivity

This study examined the main and interactive effects of maternal perceived stress and infant temperament-surgency, negative affectivity, and orienting/regulation-on infant salivary alpha-amylase (sAA) responses to stress. Saliva samples were collected prior to and following two naturalistic stressors: maternal separation conducted at 9 months and blood draw/immunizations conducted at 12 months. sAA area under the curve (AUC) was computed to determine response of the sympathetic nervous system to each stressor. Results revealed significant interactions of maternal stress and infant negative affectivity and orienting/regulation with sAA AUC. Relations between maternal stress and infant sAA AUC were stronger among infants with higher levels of negative affectivity and lower levels of orienting/regulation. These results highlight the need to examine both infant characteristics and environmental factors when investigating the development of stress response systems.

Temperament and behavior in toddlers born preterm with related clinical problems

OBJECTIVE

The aim of this study was to compare temperament and behavior profiles among groups of preterm toddlers differentiated by level of prematurity and the presence of bronchopulmonary dysplasia (BPD) or retinopathy of prematurity (ROP), controlling for neonatal clinical conditions and chronological age.

METHOD

The sample comprised 100 preterm toddlers segregated according to level of prematurity (75 very preterm and 25 moderate/late preterm) and presence of BPD (n=36) and ROP (n=63). Temperament was assessed by the Early Childhood Behavior Questionnaire and behavior by the Child Behavior Checklist. The MANOVA was performed with a post-hoc univariate test.

RESULTS

The level of prematurity and the presence of BPD and ROP did not affect temperament and behavioral problems in toddlers born preterm. However, the covariates age and length of stay in NICU (Neonatal Intensive Care Unit) affected temperament and behavioral problems, respectively. The older toddlers showed higher inhibitory control and lower activity levels than younger toddlers (range of 18-36months-old). Additionally, toddlers who stayed in the NICU longer showed more pervasive development and emotionally reactive problems than toddlers who stayed in NICU for less time.

CONCLUSION

The level of prematurity and the presence of bronchopulmonary dysplasia and retinopathy of prematurity did not affect temperament and behavioral problems in toddlers born preterm. However, a longer stay in the NICU increased the risk for behavioral problems, and age enhanced the regulation of temperament at toddlerhood.

Testing Reciprocal Links Between Trouble Getting to Sleep and Internalizing Behavior Problems, and Bedtime Resistance and Externalizing Behavior Problems in Toddlers

Sleep problems are associated with problematic adjustment in toddlers, but less is known regarding the direction of association between specific sleep problems and adjustment. To address this gap, we used data from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development (N = 1001) to examine reciprocal associations between sleep problems and behavior problems from 24- to 36-months. Results from cross-lagged path models suggested specificity of associations between type of sleep problem and behavior problem. Specifically, there were reciprocal associations between trouble getting to sleep and internalizing problems, and unidirectional links between externalizing problems and bedtime resistance from 24- to 36-months. Internalizing and externalizing problems at 24 months, however, predicted increases in bedtime resistance from 24- to 36-months for boys, but not girls. Findings highlight specific relations between sleep problems and internalizing and externalizing problems during toddlerhood, and the importance of examining sex differences.

The link between infant regulatory problems, temperament traits, maternal depressive symptoms and children's psychopathological symptoms at age three: a longitudinal study in a German at-risk sample

BACKGROUND

Difficult conditions during childhood can limit an individual's development in many ways. Factors such as being raised in an at-risk family, child temperamental traits or maternal traits can potentially influence a child's later behaviour. The present study investigated the extent of regulatory problems in 6-month-old infants and their link to temperamental traits and impact on externalizing and internalizing problems at 36 months. Moderating effects of maternal distress and maternal depressive symptoms were tested as well.

METHODS

In a quasi-experimental, longitudinal study, a sample of 185 mother-infant dyads at psychosocial risk was investigated at 6 months with SFS (infants' regulatory problems) and at 3 years with CBCL (children's behavioural problems), EAS (children's temperament), ADS (maternal depressive symptoms) and PSI-SF (maternal stress).

RESULTS

A hierarchical regression analysis yielded a significant association between infants' regulatory problems and both externalizing and internalizing behaviour problems at age 3 (accounting for 16% and 14% variance), with both externalizing and internalizing problems being linked to current maternal depressive symptoms (12 and 9% of the variance). Externalizing and internalizing problems were found to be related also to children's temperamental difficulty (18 and 13% of variance) and their negative emotionality. With temperamental traits having been taken into account, only feeding problems at 6 months contributed near-significant to internalizing problems at 3 years.

CONCLUSIONS

Our results underscore the crucial role of temperament in the path between early regulatory problems and subsequent behavioural difficulties. Children's unfavourable temperamental predispositions such as negative emotionality and generally "difficult temperament" contributed substantially to both externalizing and internalizing behavioural problems in the high-risk sample. The decreased predictive power of regulatory problems following the inclusion of temperamental variables indicates a mediation effect of temperamental traits in the path between early regulatory problems and subsequent behavioural problems. Our results support the main effects of a child's temperament, and to some degree maternal depressive symptoms, rather than the diathesis stress model of interaction between risky environment and temperamental traits.
