Environmental Adversity and Children's Early Trajectories of Problem Behavior: The Role of Harsh Parental Discipline

This study was performed to examine the role of harsh parental discipline in mediating and moderating the effects of environmental adversity (family socioeconomic disadvantage and adverse life events) on emotional and behavioral problems across early-to-middle childhood. The sample included 16,916 children (48% female; 24% non-White) from the U.K.’s Millennium Cohort Study. We analyzed trajectories of conduct, hyperactivity, and emotional problems, measured at ages 3, 5, and 7 years, using growth curve models. Harsh parental discipline was measured at these ages with parent-reported items on the frequency of using the physical and verbal discipline tactics of smacking, shouting at, and “telling off” the child. As expected, family socioeconomic disadvantage and adverse life events were significantly associated with emotional and behavioral problems. Harsh parental discipline was related to children’s trajectories of problems, and it moderated, but did not explain, the effect of environmental risk on these trajectories. High-risk children experiencing harsh parental discipline had the highest levels of conduct problems and hyperactivity across the study period. In addition, harsh parental discipline predicted an increase in emotional symptoms over time in high-risk children, unseen in their counterparts experiencing low levels of harsh parental discipline. However, children in low-risk families were also negatively affected by harsh parental discipline concurrently and over time. In conclusion, harsh parental discipline predicted emotional and behavioral problems in high- and low-risk children and moderated the effects of family poverty and adversity on these problems

School composition, family poverty and child behaviour

PURPOSE: There is little research on the role of school composition in young children's behaviour. School composition effects may be particularly important for children in disadvantaged circumstances, such as those growing up in poverty. We explored the role of school academic and socio-economic composition in internalising problems, externalising problems and prosocial behaviour at age 7 years, and tested if it moderates the effect of family poverty on these outcomes. METHODS: We used data from 7225 7-year-olds of the Millennium Cohort Study who attended state primary schools in England and for whom we had information on these outcomes. In multiple membership models, we allowed for clustering of children in schools and moves between schools since the beginning of school, at age 5. Our school academic and socio-economic composition variables were school-level achievement and % of pupils eligible for free school-meals, respectively. Poverty (family income below the poverty line) was measured in all sweeps until age 7. We explored the roles of both timing and duration of poverty. RESULTS: The effects of poverty were strong and robust to adjustment. School socio-economic composition was associated with individual children's internalising and externalising problems, even in adjusted models. School composition did not interact with poverty to predict any of the outcomes. CONCLUSIONS: Neither the academic nor the socio-economic composition of the school moderated the effect of family poverty on children's behaviour in primary school. However, children attending schools with more disadvantaged socio-economic intakes had more internalising and externalising problems than their counterparts

Socio-economic status and family structure differences in early trajectories of child adjustment: Individual and neighbourhood effects

We examined the effects of single-parent family status and high parental socio-economic status (SES) on the trajectories of children's emotional/behavioural adjustment in early-to-middle childhood (ages 3-7 years). We also assessed whether these family characteristics interact with the equivalent neighbourhood characteristics of shares of single-parent families and high-SES adults in predicting these trajectories. Using data on 9850 children in England participating in the Millennium Cohort Study, we found that family status and parental SES predicted children's trajectories of adjustment. Even after controlling for these family factors and key child and parent characteristics, the neighbourhood shares of high-SES adults and single-parent families were related (negatively and positively, respectively) to child problem behaviour. Importantly, children of low-SES parents in neighbourhoods with a high concentration of high-SES adults had fewer emotional symptoms than their counterparts in areas with fewer high-SES adults. Surprisingly, the adverse effect of single-parent family status on child hyperactivity was attenuated in areas with a higher share of single-parent families

Maternal depression and trajectories of child internalizing and externalizing problems: the roles of child decision making and working memory

BACKGROUND: Maternal depression may affect the emotional/behavioural outcomes of children with normal neurocognitive functioning less severely than it does those without. To guide prevention and intervention efforts, research must specify which aspects of a child's cognitive functioning both moderate the effect of maternal depression and are amenable to change. Working memory and decision making may be amenable to change and are so far unexplored as moderators of this effect. METHOD: Our sample was 17 160 Millennium Cohort Study children. We analysed trajectories of externalizing (conduct and hyperactivity) and internalizing (emotional and peer) problems, measured with the Strengths and Difficulties Questionnaire at the ages 3, 5, 7 and 11 years, using growth curve models. We characterized maternal depression, also time-varying at these ages, by a high score on the K6. Working memory was measured with the Cambridge Neuropsychological Test Automated Battery Spatial Working Memory Task, and decision making (risk taking and quality of decision making) with the Cambridge Gambling Task, both at age 11 years. RESULTS: Maternal depression predicted both the level and the growth of problems. Risk taking and poor-quality decision making were related positively to externalizing and non-significantly to internalizing problems. Poor working memory was related to both problem types. Neither decision making nor working memory explained the effect of maternal depression on child internalizing/externalizing problems. Importantly, risk taking amplified the effect of maternal depression on internalizing problems, and poor working memory that on internalizing and conduct problems. CONCLUSIONS: Impaired decision making and working memory in children amplify the adverse effect of maternal depression on, particularly, internalizing problems

School poverty effects on trajectories of child behaviour: Do they depend on gender and ethnicity?

This study examined English school poverty effects on trajectories of child behaviour across ages 3, 5, 7 and 11, and the moderating roles of ethnicity and gender. School poverty predicted internalising and externalising problems concurrently, and internalising problems longitudinally. In poor schools, girls had a steeper incline in internalising problems, but made greater reductions in externalising problems. Ethnic differences were also found in the association between school poverty and child adjustment. Gender and ethnic background may influence how a child responds emotionally and behaviourally to the composition of peers at school

Family and neighbourhood risk and children's problem behaviour: The moderating role of intelligence

General cognitive ability ('general intelligence') has been shown to buffer the effects of family adversity and poverty on emotional and behavioural problems in school age children. Yet, little is known about whether it can protect younger children or change the problem trajectories of at-risk children. We modelled simultaneously the effects of family poverty, neighbourhood poverty and adverse family events on children's trajectories of emotional and behavioural problems at ages 3, 5 and 7. We then tested the role of general intelligence both in changing the trajectories of problems and in buffering the effects of these risk factors at each age, and explored gender differences in its expected protective effects. We analyzed data on 16,916 children from the UK Millennium Cohort Study. General intelligence was derived from principal components analysis of several cognitive ability measures at ages 3, 5 and 7. Although general intelligence was not associated with the growth of at-risk children's problems over time, it was associated with the level of positive emotional and behavioural outcomes, and conferred concurrent protection from risk. At age 5, poor children with higher general intelligence had fewer emotional problems than similarly poor children with lower intelligence. Children exposed to family adversity were less likely to have emotional problems at any age if they had higher general intelligence. Higher general intelligence was also related to fewer behavioural problems for children experiencing family adversity at age 5, but not at ages 3 or 7. General intelligence moderated the effect of neighbourhood poverty on behavioural problems at ages 3 and 7, and its effect on emotional problems at age 5. In general, the protective effects of general intelligence, especially for emotional outcomes, applied mainly to girls. General intelligence appears to assist children in building resilience to both family and neighbourhood risk across childhood

The Relationship Between Father Involvement and Child Problem Behaviour in Intact Families: A 7-Year Cross-Lagged Study

This study investigated the cross-lagged relationship between father involvement and child problem behaviour across early-to-middle childhood, and tested whether temperament modulated any cross-lagged child behaviour effects on father involvement. It used data from the first four waves of the UK’s Millennium Cohort Study, when children (50.3 % male) were aged 9 months, and 3, 5 and 7 years. The sample was 8302 families where both biological parents were co-resident across the four waves. Father involvement (participation in play and physical and educational activities with the child) was measured at ages 3, 5 and 7, as was child problem behaviour (assessed with the Strengths and Difficulties Questionnaire). Key child and family covariates related to father involvement and child problem behaviour were controlled. Little evidence was found that more father involvement predicted less child problem behaviour two years later, with the exception of father involvement at child’s age 5 having a significant, but small, effect on peer problems at age 7. There were two child effects. More hyperactive children at age 3 had more involved fathers at age 5, and children with more conduct problems at age 3 had more involved fathers at age 5. Child temperament did not moderate any child behaviour effects on father involvement. Thus, in young, intact UK families, child adjustment appears to predict, rather than be predicted by, father involvement in early childhood. When children showed more problematic behaviours, fathers did not become less involved. In fact, early hyperactivity and conduct problems in children seemed to elicit more involvement from fathers. At school age, father involvement appeared to affect children’s social adjustment rather than vice versa

Do upsetting life events explain the relationship between low socioeconomic status and systemic inflammation in childhood? Results from a longitudinal study

BACKGROUND Children from families of low socioeconomic status (SES) are more likely to be exposed to upsetting situations and stressors. Such exposures have, in turn, been linked to inflammation in some studies. In this study we explore if low SES is related to inflammation in children via such stressful life events. METHODS Data on 4,525 children of the Avon Longitudinal Study of Parents and Children, a general population birth cohort, were used to explore associations between SES at ages 0-3 years, upsetting life events at ages 3-9 years and inflammatory markers [interleukin 6 (IL-6) and C-reactive protein (CRP)] at age 9 years. Confounders included body mass index, gender, financial problems, and upsetting life events at ages 0-3 years. RESULTS Using Structural Equation Modelling, we found that early socioeconomic disadvantage predicted higher levels of IL-6 (β=0.034, 95% CI=0.063, 0.005) even after adjusting for confounders. This association was partially mediated by upsetting life events (β=0.003, 95% CI=0.011, 0.001). CONCLUSIONS In the general child population, low SES is associated with increased exposure to stressful life events, in turn associated with later inflammation. These findings highlight the role of stressors associated with poverty and disadvantage in the development of inflammation among children in the general population

Social media use and adolescents’ self-esteem and appearance satisfaction: The moderating role of school motivation

Background: This large-scale investigation speaks to the growing concern associated with the use of social media on the psychological wellbeing of adolescents. The study explored time spent using social networking sites as a predictor of teenagers’ self-esteem and appearance satisfaction and the protective role that motivation in school might play. Method: The sample comprised 10,546 adolescents at age 11 and 14 years, from the UK’s Millennium Cohort Study. Multiple linear regression determined cross-sectional and longitudinal associations between use of social media and self-esteem and appearance satisfaction. Time spent using social networking sites significantly predicted teenagers’ self-esteem and appearance satisfaction levels. Results: A significant interaction emerged with school motivation and social networking in relation to appearance satisfaction, suggesting that school motivation may help to buffer the negative effects of online social networking. Conclusion: In response to the ongoing concerns around the increase in adolescents who struggle with difficulties relating to their mental health, the finger of blame is frequently pointed to screen-based methods of social communication. It is anticipated that present findings will prompt the development of new interventions that target time spent using online social networking sites, particularly among teenage girls, during this new era of COVID-19-induced social isolation

Maternal psychological distress and child decision-making

Background: There is much research to suggest that maternal psychological distress is associated with many adverse outcomes in children. This study examined, for the first time, if it is related to children's affective decision-making. Methods: Using data from 12,080 families of the Millennium Cohort Study, we modelled the effect of trajectories of maternal psychological distress in early-to-middle childhood (3–11 years) on child affective decision-making, measured with a gambling task at age 11. Results: Latent class analysis showed four longitudinal types of maternal psychological distress (chronically high, consistently low, moderate-accelerating and moderate-decelerating). Maternal distress typology predicted decision-making but only in girls. Specifically, compared to girls growing up in families with never-distressed mothers, those exposed to chronically high maternal psychological distress showed more risk-taking, bet more and exhibited poorer risk-adjustment, even after correction for confounding. Most of these effects on girls’ decision-making were not robust to additional controls for concurrent internalising and externalising problems, but chronically high maternal psychological distress was associated positively with risk-taking even after this adjustment. Importantly, this association was similar for those who had reached puberty and those who had not. Limitations: Given the study design, causality cannot be inferred. Therefore, we cannot propose that treating chronic maternal psychological distress will reduce decision-making pathology in young females. Conclusions: Our study suggests that young daughters of chronically distressed mothers tend to be particularly reckless decision-makers
