We studied the association of early-life environmental and child factors with disruptive behaviors in children with autistic traits around age 7, in the Avon Longitudinal Study of Parents and Children (n = 6,401). Logistic regression with the least absolute shrinkage and selection operator indicated that disruptive behaviors were associated with…

Mounting evidence finds that early life environmental factors increased the probability of autism spectrum disorder. We estimated prospective associations between early life environmental factors and autism spectrum disorder symptoms in children at the age of 2 years in a population-derived birth cohort, the Barwon Infant Study. Autism spectrum…

Background: The longitudinal impact of fetal growth on attention problems in males and females is unclear. This study aims to evaluate the impact of fetal growth assessed by neonatal anthropometry throughout childhood and adolescence in males and females separately. Methods: We compared neonatal anthropometry (birth weight (BW), head circumference…

Physical abuse is one subtype of child abuse and it has been a worldwide public health issue for its detrimental effects on child development, profiles, predictors, and its relation with behavior problems need further exploration, particularly in Chinese children. This study attempts to explore profiles and predictors of physical abuse and to…

Most U.S. children grow up with siblings. Theory and prior work suggest that older siblings are important sources of gender-related information and socialization. However, few studies have investigated the patterns of these associations longitudinally across early childhood. The present study examines the influence of sibling presence and gender…

This study examines interactions of heritable influences, prenatal substance use, and postnatal parental warmth and hostility on the development of conduct problems in middle childhood for boys and girls. Participants are 561 linked families, collected in 2 cohorts, including birth parents, adoptive parents, and adopted children. Heritable…

Understanding children's willingness to take risks is crucial for sound educational strategies and play environments. This study investigates children's risk willingness using a virtual reality (VR) playground balancing scenario and examines its associations with sensation-seeking personality trait, age, gender, and the likelihood of failing the…

This study examined longitudinal associations between parental psychological distress (stress and depression) when the child was 2 to 4 years and a child's emotional and behavioural problems at ages 3 to 4, and social functioning (loneliness and social competence) at age 11 in very preterm born children. The participants were Finnish families of…

Across all cultures, parents have intuitive ideas ("ethnotheories") of what undesirable child characteristics are as well as how to explain them. Yet there have been relatively few cross-cultural comparisons of parents' ethnotheories about the nature and causes of child misbehavior. 108 mothers of 5-year-old children from the United…

Outdoor time is a positive correlate of physical activity in preschoolers; however, children remain highly sedentary even outdoors. This cross-sectional study thus aimed (1) to measure the physical activity levels of 30 preschool-aged children attending a centre-based childcare centre in a remote region located in Northwestern Québec (Canada) and…

Early adversity is associated with both internalizing and externalizing problems among children, and effects of adversity on dimensions of child temperament may underlie these links. However, very little is known about the role of child sex in these processes. The current study examined whether there are indirect effects of early adversity on…

This study explored parents' ways of coping with their children's problem behaviors and their perceptions of causality. The study group was composed of 164 children aged 7-12 years (84 females and 80 males) and their parents (120 mothers and 44 fathers). In order to collect data, "General Information Form" for the demographical…

Research has shown links between emotion regulation strategies and child mental health. However, it is not well known how the characteristics of children may moderate these links. The aim of this study was to explore whether environmental sensitivity--the ability to perceive and process information about the environment--moderates links between…

Emotional and behavioural problems occur more commonly in children with Autism Spectrum Disorder (ASD) compared to other children. Few studies have focused on these problems in children with ASD attending mainstream schools. We assessed via parent report the emotional and behavioural problems in 160 children aged 4-17 years with ASD attending…

Clinically meaningful behavior problems are thought to be present beginning in the early toddler years, yet few studies have investigated correlates of behavior problems assessed before age 2 years. The current study investigated the direct and interactive contributions of early infant and caregiver characteristics thought to play an important…
