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…

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…

The important role of early self-regulation skills has been repeatedly demonstrated in research. However, there is a lack of studies that have simultaneously examined the influence of hot and cool self-regulation skills on school performance and behavior problems in a longitudinal design from preschool to elementary school and controlling…

Background: Relational victimization (RV) is a significant threat to adolescent mental health and social adaptation in China. However, its developmental characteristics during the school transition period are poorly understood. Finkelhor's developmental victimology framework provides a comprehensive lens to explore factors influencing RV's…

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…

Selective non-participation and attrition pose a ubiquitous threat to the validity of inferences drawn from observational longitudinal studies. We investigate various potential predictors for non-response and attrition of parents as well as young persons at different stages of a multi-informant study. Various phases of renewed consent from parents…

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…

The transition from preschool to elementary school requires high adaptive behaviours. Our study's aim is to analyze the reciprocal effects between self-regulation and behaviour problems during this transitional phase. Study results are based on longitudinal data collected at preschool and elementary school. Children's level of behaviour problems…

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…

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…

Behavioral inhibition (BI) is an early-appearing temperamental trait characterized by intense negative affect and withdrawal behaviors to novel and challenging situations. Inhibited children are more likely to display social withdrawal and experience an increased risk for internalizing problems. Trait inference, the way children interpret…

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…

Research has consistently shown that difficulties in facial emotion recognition (FER) are associated with peer problems and internalizing symptoms during middle childhood. However, no longitudinal research has investigated the direction of effects, that is, how these constructs influence each other across time. In this preregistered three-wave…

Research suggests that a childhood diagnosis of Autism Spectrum Disorder (ASD) or Attention Deficit Hyperactivity Disorder (ADHD) is associated with poorer teacher-child relationship quality and higher rates of externalising behaviours. It is proposed that the socio-emotional problems experienced by those children with ASD and/or ADHD lead to poor…

Considerable studies have shown the protective effects of breastfeeding on internalizing problem behaviours in early childhood, yet little is known about the groundwork for this relationship. This study attempted to test the hypothesis that improvement of mothers' positive parenting behaviours by breastfeeding can explain the relationship. We used…
