Developmental researchers commonly utilize longitudinal data to decompose reciprocal and dynamic associations between repeatedly measured constructs to better understand the temporal precedence between constructs. Although the cross-lagged panel model (CLPM) is commonly used in developmental research, it has been criticized for its potential to…

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…

Peer victimization in schools is a growing concern in China, linked to increased emotional difficulties and behavioral difficulties. A positive school climate may serve as a protective factor against both peer victimization and its adverse outcomes. This study examined the longitudinal relations between peer victimization, aggression, and school…

Up to 80% of children with autism spectrum disorder (ASD) experience sleep problems, which have been associated with more severe presentations of ASD symptoms. We examined the bidirectional link between sleep problems and specific ASD symptoms at two time points within 5 years in a well-characterized sample (659 children with ASD). Using…

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…

Social adjustment is critical to educational and occupational attainment. Yet little research has considered how the school's socioeconomic context is associated with social adjustment. In a longitudinal sample of Australian 4- to 8-year-olds (N = 9369; 51% boys) we tested the association between school average socioeconomic status and social…

Externalizing behavior and low academic performance present key developmental challenges for school-age children, with the potential for these domains to predict each other over time, leading to worsened outcomes. Yet, previous studies have yielded inconsistent conclusions about the directional pathways between externalizing behaviors and academic…

Structural equation modelling (SEM) with longitudinal survey data was used to test a proposed developmental model of the association of family income (with children aged 6-9) to parent behaviours (for children at 10 years of age) and adolescent cognitive achievement and behaviour problems (at age 15). Data from the Child Development Supplement and…

The aim of the present study was to explore how maternal reminiscing relates to socioemotional development during middle childhood. Specifically, analyses explored the link between maternal reminiscing and children's internalizing (emotional problems and peer problems), externalizing (hyperactivity and conduct problems) and prosocial behavior…

Autistic students often experience peer relationship difficulties. As peer acceptance and rejection may be malleable over time, we examined predictors of change in peer acceptance and peer rejection among early elementary-age autistic students. We followed 166 autistic children (mean age: 6.1 years [range: 4-8], 82.5% boys, grades preK-2nd)…

Background: Bullying has a profound and enduring impact on academic achievement. However, there is a lack of clarity surrounding the specific mechanisms of this relationship. Aims: This study examined the link between bullying at age 9 and Numeracy/Literacy achievement at age 15 to determine if this relationship is partially or fully explained by…

Objective: Children with ADHD often experience functional impairments across various aspects of daily life. This study addresses the dearth of longitudinal research on functional impairment trajectories from preschool to school age in children with symptoms of ADHD and comorbid disorders. Methods: We investigated the extent to which functional…

Intrusive parenting has been traditionally considered a negative parenting style and includes actions that are overly directive and controlling of children's behavior. However, current research aims to contextualize this parenting behavior. This study examined the relation between intrusive parenting and early childhood behavior problems or…

This study evaluated whether a theory-based intervention in physical education (PE) designed to train self-control may positively impact children's quick-temperedness and disruptiveness and whether changes in executive functions (EFs) may be a correlate or antecedent of such effects. One hundred and sixteen children aged 8-9 years participated in…

Background: Both transactional and common etiological models have been proposed as explanations of why externalizing behavior problems (EBP) and internalizing behavior problems (IBP) co-occur in children. Yet little research has empirically evaluated these competing theoretical explanations. We examined whether EBP and IBP are transactionally…
