Background: Positive marital relations are crucial for healthy family functioning, whereas conflict-ridden marital relations are linked to children's adjustment problems. According to the Emotional Security Theory, destructive interparental conflict leads to children's emotional insecurity, impacting their adjustment. Objective: This three-wave…

This study explored how caregiver-reported executive functioning domains, assessed by the BRIEF2 at baseline, predicted behavioral challenges reported by caregivers using the CBCL six months later. The sample included 94 youth with Down syndrome, aged 6 to 18 years. Results of hierarchical regression analyses revealed that, after controlling for…

Early academic skills and behavioral characteristics in students are predictive of later school achievement, but academics and behavior are commonly compartmentalized in research and practice. This study investigated to what extent first-grade early numeracy (EN), literacy, and behavior ratings predicted fourth-grade mathematics achievement. In…

Guided by developmental models examining the legacy of childhood caregiving environments, we examined the longitudinal pattern of associations between harsh parenting and children's internalizing and externalizing symptoms across late childhood to late adolescence. Participants included 199 youth (48.7% female, 65.3% White, 32.2% Black, 2.5%…

Background: Studies suggest that prosocial behavior, having high empathy and engaging in behaviors intended to benefit others, may predict mental health or vice versa; however, these findings have been mixed. The purpose of the current study was to examine the bidirectional relationships between prosocial behavior and dimensions of psychopathology…

Screens have become increasingly prevalent in children's lives. This study examined the longitudinal association between screen time and aggressive behaviour by investigating the mediating and moderating roles of language ability and parenting stress, respectively. The analysed data consisted of 1,319 children, aged 5 to 15, from the Fragile…

In this registered report, we evaluated how sleep is related to school functioning. Using data from the Future of Families and Child Wellbeing Study (N = 3002), we evaluated a series of structural equation models evaluating whether sleep at age 5 has a direct or indirect effect on academic achievement, executive function and classroom behaviour at…

Dietary intake can affect the physical, cognitive, and socioemotional development of young children. Few studies have explored the relationships between dietary intake and the cognitive and socioemotional dimensions of school readiness. This study aimed to investigate the longitudinal associations between children's dietary intake in early…

Paternal incarceration is an important predictor of teen delinquency, but the factors that may explain this relationship--such as early child problem behaviors and level of father engagement--have not been adequately explored. The current longitudinal study examined paternal history of incarceration as a predictor of teen self-reported delinquency…

Technology use among preschool-aged children (3 to 5 years old) is increasing significantly. Most of this use occurs at home, however, there is little research that investigates how it is affecting family relations and dynamics. This comparative case study explores the social practices of mobile technology in two families with preschool-aged…

We investigated longitudinal relations between internalizing, externalizing, and total behaviors that challenge in young children on the autism spectrum and mothers' parenting stress. Participants included 93 mothers of children on the autism spectrum aged 27.89-65.84 months, who completed questionnaires on maternal parenting stress, and…

This study analysed whether the assessment of head righting reflex (HRR) in babies immediately after birth can be used in prediction of early child development. In 54 healthy newborns, testing of HRR was conducted on the third day upon birth. The HRR at birth were correlated with balance ability (BA), speech and language development (SLD) and…

Purpose: Behavior and temperament (e.g., emotional reactivity, self-regulation) have been considered relevant to stuttering and its developmental course, but the direction of this relation is still unknown. Knowledge of behavior difficulties and temperament in childhood stuttering can improve screening and intervention. The current study examined…

Self-regulation is thought to show heterotypic continuity--its individual differences endure but its behavioral manifestations change across development. Thus, different measures across time may be necessary to account for heterotypic continuity of self-regulation. This longitudinal study examined children's (N = 108) self-regulation development…

From early in life, children learn to perform actions on the objects in their environments. Although children learn from observing others' actions, actively engaging with the material to be learned can be important for learning. This study tested whether instruction that included opportunities for children to be active supported toddlers' action…
