This study aimed to introduce an ego-resiliency questionnaire for preadolescents (the ER-P) by restructuring the ER89 using the data of 1398 preadolescents from the Panel Study on Korean Children. The ER-P was proposed as a 10-item second-order instrument with two factors (Optimal Regulation and Openness to Life Experiences). The ER-P achieved…

Although research has investigated the association between pathological gaming and academic performance in adolescence, the complexity of the relationship has not been thoroughly examined. This short longitudinal study aimed to investigate the interactions between pathological gaming, academic self-efficacy, academic initiative, and academic…

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…

Continuity of pre-k and kindergarten classroom experiences is a key area of interest for early childhood researchers interested in supporting public pre-k children's development over time. To advance the empirical evidence on this topic, this study examined whether differences in classroom experiences as children transition from pre-k to…

Effortful control and intentional self-regulation are two constructs associated with children's and adolescent self-regulation that have historically been the subject of research in separate fields, where temperament research has primarily focused on effortful control, and positive development research has focused on intentional self-regulation.…

The present study examined the intraindividual, longitudinal, cross-lagged associations between adolescents' perceptions of mothers' and fathers' psychologically controlling parenting and their self-regulation from ages 11-17. Using 7 waves of data involving 500 families and their adolescents (M[subscript age] = 11.29; SD = 1.01 at Wave 1),…

We assessed the psychometric properties of the Social Behavior Questionnaire (SBQ), a 30-item questionnaire evaluating social (e.g., disruptive behaviors, bullying) and emotional problems (e.g., anxiety, depression) among children aged 3.5-12 years. Children (n = 1,950, 50.21% boys) were drawn from the Quebec Longitudinal Study of Child…

Background: Temperament has been associated with child anxiety in a number of studies; however, research examining possible mechanisms of effect using longitudinal designs is scarce. Objective: This study tested a theoretically-derived model of anxiety development spanning infancy (6 months) to early childhood (approximately 72 months) that…

The moderating effects of motivation, social control, and self-regulation in predicting academic achievement were examined in Grades 11-12 for 3,281 seventh through nine graders. Standardized assessments of college readiness and student self-reported measures of psychosocial factors were used in the study. The results showed that females in Grades…

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;…

We used structural equation modeling in the Early Childhood Longitudinal Study--Kindergarten Cohort (N = 17,020) to explore the influence of having an older sibling on kindergarten-age focal children's cognitive self-regulation. In model 1, we tested how having a sibling who is generally older than the focal child contributes to the focal child's…

Daytime sleepiness and different symptoms are common problems affecting health and well-being of schoolchildren. This population-based cohort study included 568 children who were followed from ages 10 to 15 years. Daytime sleepiness, headache, abdominal pain, and psychological symptoms (depression, irritability or bad temper, nervousness, anxiety,…

Executive functions (EFs) may help children to regulate their food-intake in an "obesogenic" environment, where energy-dense food is easily available. There is mounting evidence that overweight is associated with diminished hot and cool EFs, and several longitudinal studies found evidence for a predictive effect of hot EFs on children's…

Aims: To determine whether distinct trends can exist in children's diurnal cortisol slopes as they transition to school, and the extent to which these trends relate to preschool attendance and/or exerted effortful control. Method: A secondary analysis of the anonymised data gathered for the UK Transition to School Study was carried out. 105…

The development of early childhood self-regulation is often considered an early life marker for later life successes. Yet little longitudinal research has evaluated whether there are different trajectories of self-regulation development across children. This study investigates the development of behavioral self-regulation between the ages of 3 and…
