Latent growth curve modeling was used to investigate the longitudinal link between attachment, effortful control (EC), and maladaptive development during middle childhood. In a community sample, children (Time 1: n = 157; M[subscript age] = 10.91) and their mothers were examined three times over a two-year period. Attachment was operationalized at…

Purpose: Early language difficulties are associated with later internalizing problems across different ages and for different aspects of language. The mechanisms behind this association are, however, less understood. In the current study, we investigated longitudinal associations between language difficulties at 5 years and internalizing problems…

This study aimed to examine the effect of attachment security in 17-month-olds on their peer play interactions and behavioural problems at ages 4 and 6 years, respectively, in Korea. By employing structural equation modelling, we analyzed the data of 183 children and their mothers, which were extracted from the Panel Study on Korean Children…

Few longitudinal studies examine how "changes" in parent-child relationships are associated with changes in youth internalizing problems. In this longitudinal study, we investigated how developmental trends (linear change) and year-to-year lability (within-person fluctuations) in parental warmth and hostility across Grades 6 to 8 predict…

In this study, we explored how free play and scaffolding practices in Early Childhood Education and Care (ECEC) related to children's externalising problems both in ECEC and later in school. Furthermore, we aimed to reduce the knowledge gap of whether these relations depended on children's differences in emotional temperament. We used structural…

Exposure to intimate partner violence (IPV) is associated with children's internalizing and externalizing problems. IPV is thought to impair mothers' ability to scaffold young children's emotion regulation through coregulated interactions. Mother-child language style matching (LSM) is an index of coregulation that has yet to be examined in…

This study examined the protective roles of early prosocial behaviours (at age 4) on later internalizing and externalizing problems (at age 6) and to what extent emotion regulation skills (at age 5) mediated these longitudinal associations in children from Turkey. Participants were 293 Turkish preschool children (M[subscript age] = 49.01 months;…

Peer victimization is a well-established risk factor for children's internalizing problems. We longitudinally examined the moderating role of children's early perceptions of positive peer relationships and inhibitory control on the association between peer victimization at age 6 and internalizing symptoms at age 10. Perceptions of peer…

The purpose of this study was to examine the longitudinal, bidirectional relationship between language skills and behavior problems in a sample of 194 preschool children enrolled in Head Start programs. Children were individually assessed using the "Preschool Language Scale-5," and teachers completed the "Child Behavior…

This longitudinal study examined the moderating roles of language use and gender in the relations between maternal depressive symptoms and child internalizing behaviour problems in 242 preschool children (48% girls) enrolled in Head Start centres. Teachers and parents completed the "Child Behavior Checklist for Ages 1 1/2-5." Mothers…

In line with family systems theory, we examined patterns of hostile interactions within families and their associations with externalizing problems among early-adolescent children. Using hostility scores based on observational data of six dyadic interactions during a triadic interaction (n = 462; i.e., child-to-mother, mother-to-child,…

The Dual Failure Model suggests that peer victimization (social failure) and academic difficulties (academic failure) mediate the association between externalizing and later internalizing problems. The present study sought to better understand why children with externalizing problems develop later internalizing problems by testing the Dual Failure…

The developmental significance of youths' racial identities during adolescence is well established. It is less clear how puberty, a normative process, influences the relationship between racial identity and adjustment outcomes during adolescence. This study examined whether puberty moderates the relationship between racial identity dimensions and…

An extensive literature links language problems with behavioral difficulties and academic underachievement. Although less extensive, emerging literature suggests that temperament, Positive Affectivity (PA) in particular, contributes to language development. Thus, the present study was focused on PA related temperament dimensions in infancy as…

Why do men in the United States today complete less schooling than women? One reason may be gender differences in early self-regulation and prosocial behaviors. Scholars have found that boys' early behavioral disadvantage predicts their lower average academic achievement during elementary school. In this study, I examine longer-term effects: Do…
