The directionality and longitudinal course between perfectionism and academic achievement throughout adolescence remains unclear as most studies rely on cross-sectional or short-term data and many examine these associations in university students who do not represent the full spectrum of learners. Moreover, most studies are hampered by their…

What is the relationship between academic buoyancy and academic adversity? For example, does the experience of academic adversity help build students' academic buoyancy in school--or, does academic buoyancy lead to decreases in subsequent academic adversity? This longitudinal study of 481 high school students (Years 7-12) investigated the…

This study aimed to develop and evaluate a new parent-report measure to assess primary schoolchildren's academic behaviors in the home context. We developed the Academic Behavior Scale (ABS) and administered it to Chinese parents of primary schoolers along with other measures. Six hundred and forty-five parents and 170 primary schoolchildren in…

Poor sleep is thought to interfere with children's learning and academic achievement (AA). However, existing research and theory indicate there are factors that may mitigate the academic risk associated with poor sleep. The purpose of this study was to examine the moderating role of children's effortful control (EC) on the relation between sleep…

We investigated the relationship of self-sexualization to self-objectification, weight concerns, self-efficacy, academic outcomes, and career aspirations among preadolescent girls. Participants were 89 six- to nine-year-old girls; parental reports were also obtained. Two thirds of girls showed signs of self-sexualization by choosing a sexualized…

The concurrent and longitudinal associations between popularity, likeability, and prosocial behavior were evaluated in this three-year study of middle school and high school Chinese adolescents. The initial sample included 766 middle school (mean age = 13.3 years) and 668 high school participants (mean age = 16.6 years); there were 880 (399 girls)…

Children with conduct problems are at greater risk for internalizing problems. The objectives of this study were to (1) examine trajectories of internalizing problems among children with and without clinically significant conduct problems during the transition to adolescence; and (2) identify how academic achievement, peer rejection, parent…

School engagement involves cognitive, emotional, and behavioral components that overlap conceptually. This conceptual ambiguity has led to measures that have either consisted of one general factor or separate correlated factors. However, neither approach can sufficiently account for both the uniqueness and the overlap of the subcomponents. The…

This study examined the longitudinal associations between children's academic skills and the instructional support teachers gave individual students. A total of 253 Finnish children were tested on reading and math skills twice in the first grade and once in the second grade. The teachers of these children rated the instructional support that they…

A strong relationship between article background and educational outcomes fuels a negative inequality cycle. This paper explores the interplay between student socioeconomic status and educational outcomes, and the mediating role of Opportunity-to-Learn (OTL) in high- and middle-income countries. Using data from PISA 2012, we find that the…

This study examined how shyness-sensitivity and unsociability were associated with social, school, and psychological adjustment in Chinese children and adolescents. Participants included 564 children (272 boys, M[subscript age] = 9 years) and 462 adolescents (246 boys, M[subscript age] = 13 years) in a suburban region in China. Data were obtained…

This study investigated how N = 5,126 adolescents (mean age of 15 years) from 18 countries perceive and cope with future- and school-related stress. The adolescents completed the Problem Questionnaire (PQ), which assesses stress, and the Coping Across Situations Questionnaire (CASQ), which assesses three coping styles (reflection/support-seeking,…

In this study we investigated whether mothers' typical expressive style and specific emotional responses to children's behaviors are linked to children's prosocial and competence self-ratings. Eight- to 12-year-old children and their mothers rated how mothers had felt when children behaved prosocially and antisocially, achieved and failed to…

Recent advances in methods and computer software for longitudinal data analysis have pushed researchers to more critically examine developmental theories. In turn, researchers have also begun to push longitudinal methods by asking more complex developmental questions. One such question involves the relationships between two developmental…

Behavioral problems are frequent among post-institutionalized Eastern European adoptees. However, risk factors related to outcomes have not been fully delineated. We evaluated 50 Eastern European adoptees, age 8-10 years, with their adoptive families for more than five years. Cognitive and behavioral outcomes and parenting stress were evaluated in…
