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…

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…

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…

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…

While scholars have studied racial bias in the application of out-of-school suspension and its influence on arrest and incarceration for decades, the mechanism that produces juvenile delinquency remains unclear. Guided by general strain theory, this study considers racial group differences in the evaluation of suspension as discriminatory, and how…

Based on a one-year longitudinal experimental study with 3,782 kindergarten school children across 15 countries, this article examines the association between prayer and happiness. Results show that the post-test scores on the faces scale were higher for the participant group who had taken the prayer lessons vis-à-vis the comparison group.…

This study examined longitudinal relations between sleep and body mass index (BMI) from late childhood ([X-bar] age = 9.44 at T1) to early adolescence ([X-bar] age = 11.36 at T3) with a relatively large (n = 273 at T1) and diverse (35% African Americans) sample. Sleep was assessed with actigraphy-based sleep minutes and self-reported sleep…

This research explored the factors of the adaptation for the children with disabilities studying in inclusive junior high schools. The subjects were recruited from the Special Needs Education Longitudinal Study of Taiwan. The result of the Confirmatory Factor Analyses reflects that there are two, three and five observed variables included in the…

This longitudinal study investigated the effects of a mastery motivational climate in physical education (PE) classes on 2×2 achievement goal orientation and dominance, self-regulated learning (SRL), and physical activity (PA) in leisure time. A total of 408 (264 women, 144 men) university students were randomly assigned to two groups:…

Purpose: Motivational processes can be set in motion when positive consequences of physical exercise are experienced. However, relationships between positive exercise experience and determinants of the motivational and the volitional phases of exercise change have attracted only sparse attention in research. Method: This research examines direct…

During high school, developing competence in science, technology, engineering, and mathematics (STEM) is critically important as preparation to pursue STEM careers, yet students in the United States lag behind other countries, ranking 35th in mathematics and 27th in science achievement internationally. Given the importance of STEM careers as…

Understanding the complex relationships among factors that may predict the outcomes of young adults with autism spectrum disorder (ASD) is of utmost importance given the increasing population undergoing and anticipating the transition to adulthood. With a sample of youth with ASD (n = 1170) from the National Longitudinal Transition Study-2,…

Although phonemic awareness is a well-known factor predicting early reading development, there is also evidence that Rapid Automatized Naming (RAN) is an independent factor that contributes to early reading. The aim of this study is to examine phonemic awareness and RAN as predictors of reading speed, reading comprehension and spelling for…

Objectives: This article reports the effects of a culturally grounded parenting intervention to strengthen positive parenting practices. Method: The intervention was designed and tested with primarily Mexican origin parents in a large urban setting of the southwestern United States using an ecodevelopmental approach. Parents (N = 393) were…

Reading strategy interventions relying upon peer tutoring are a common way to foster poor readers' comprehension skills. Those interventions are based on the assumption that tutees benefit from the (higher) reading skills of their tutors. However, this interpersonal effect has not yet been tested explicitly because the effectiveness of peer…
