To examine developmental processes, intervention effects, or both, longitudinal studies often aim to include measurement intervals that are equally spaced for all participants. In reality, however, this goal is hardly ever met. Although different approaches have been proposed to deal with this issue, few studies have investigated the potential…

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…

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 purpose of this study was to estimate the longitudinal and reciprocal predictive relations between children's social skills, measured by an adaptation of the frequently used Social Skills Rating Scale, and their standardized academic achievement. A large nationally representative sample of elementary school students were assessed at least…

Based on control-value theory (CVT), we examined longitudinal relations between students' control and value appraisals, three activity-related achievement emotions (enjoyment, anger, and boredom), and math achievement (N = 1,716 fifth and seventh grade students). We assessed appraisals and emotions with self-report measures of perceived competence…

The purpose of this study was to examine the power of phonological awareness and rapid naming longitudinally in predicting reading achievement in a highly transparent orthography, Turkish. Children were followed in kindergarten and first grade and assessed at four time points. While phonological awareness and rapid naming skills of children were…

In multilevel multiple-indicator multiple-cause (MIMIC) models, covariates can interact at the within level, at the between level, or across levels. This study examines the performance of multilevel MIMIC models in estimating and detecting the interaction effect of two covariates through a simulation and provides an empirical demonstration of…

We examined the relations between working memory, emergent literacy skills (e.g., phonological awareness, orthographic awareness, rapid-automatized naming), word reading, and listening comprehension to online reading processes (eye movements), and their relations to reading comprehension. A total of 292 students were assessed on working memory and…

This study considered the quality and stability of infant and toddler nonparental child care from 6 to 36 months in relation to language, social, and academic skills measured proximally at 36 months and distally at kindergarten. "Quality" was measured separately as caregiver-child verbal interactions and caregiver sensitivity, and…

In the current study, we investigated the developmental dynamics between positive youth development, being bullied in adolescence, gender, and sociocultural risk factors. Participants were 3,509 males (49%) and 3,656 females (51%) studied longitudinally across the ages of 9, 13, and 17 years in the Growing Up in Ireland study. Using structural…

Social anxiety is a common mental disorder with an average age of onset in early adolescence. Current theories focus largely on risk factors that are present from early in life, but reasons for onset of the disorder as youth move into adolescence are rarely discussed. We recently proposed a model of the onset of certain mental disorders during the…

Based on the interplay between achievement goals theory and social comparison theory, our study focused on how achievement goals relate to subjective well-being in the school context in Chinese adolescents. Specifically, we addressed a theoretical model that specified that academic social comparisons and self-esteem would serve as mediators in the…

Student motivation research seeks to uncover greater understanding of when, how, and why students succeed or fail in school settings. Self-determination theory has been at the forefront of helping educational stakeholders answer questions on student motivation. This study investigates the motivation mediation model proposed by self-determination…

In this two-wave longitudinal study, concurrent and longitudinal relations among teacher-reported shyness, peer acceptance, and academic achievement were examined (Ns = 162 and 155; and Ms[subscript age] = 6.09 and 7.07 years). Concurrently, at both times, shyness was negatively related to peer acceptance and academic achievement, and peer…

This study assessed the extent to which executive functions (EF), according to their factor structure in 5-year-olds (N = 244), influenced early quantity-number competencies, arithmetic fluency, and mathematics school achievement throughout first and second grades. A confirmatory factor analysis resulted in updating as a first, and inhibition and…
