Burgeoning research on the adolescent (e.g., middle-school) years suggests that this is a particularly vulnerable period for the development of maladaptive eating patterns. Prior research has established a link between perceptions of maternal parenting practices and adolescent onset of problematic eating behaviors. The authors hypothesized that…

The purpose of this study was to examine the relationships among students' self-perception, attitudes toward school, study and organizational skills, achievement motivation, attributional style, gender, parental involvement and style, parental income and parental level of education, and students' academic performance or achievement. Using…

In this article, a heterogeneous latent growth curve model for modeling heterogeneity of growth rates is proposed. The suggested model is an extension of a conventional growth curve model and a complementary tool to mixed growth modeling. It allows the modeling of heterogeneity of growth rates as a continuous function of latent initial status and…

Guided by Self-Determination and associated theories, we examined whether adolescent (N=324, Mage=15, 52% female) competence (academic engagement and achievement) were supported by relationships at school and school fit. Aspects of relationships and school fit that were measured included adolescents' perceptions of each context as promoting…

This study investigated the effects of personality and career decision-making self-efficacy on progress in career choice commitment in a sample of 184 college students. It was hypothesized that self-efficacy would mediate the relationship between neuroticism and extraversion and career choice commitment. Results revealed significant differences…

In the present study, we used a model of motivation grounded in self-determination theory (Deci & Ryan, 1985, 1991; Ryan & Deci, 2000a, 2000b, 2002) to examine the relationship between physical education (PE) students' motivational processes and ratings of their effort and persistence as provided by their PE teacher. Data were obtained…

The present study outlines a specific three-level hierarchy of the cognitive system, in particular the relationship between cognitive and metacognitive processes in mathematics. The emphasis is on the impact of processing efficiency and working memory ability on the development of self-representation and mathematical performance. We developed and…

Purpose: The environment provided by an organisation to facilitate learning and create knowledge has been defined as the shared organisational context. The value to an organisation of knowledge created by the shared organisational context is called intellectual capital, of which one key component is relational capital. The purpose of this paper is…

Concurrent and prospective associations between parent-youth dyadic hostility and adolescent externalizing and internalizing problem behavior were examined in a sample of 416 families. Parenting control, parents' well-being, and youths' affiliation with deviant peers were included as integral covariates. Information from multiple sources was…

The current study examined the influence of symptoms of attention deficit hyperactivity disorder (ADHD) on student academic achievement in reading and in mathematics in a sample of 146 first- through fourth-grade students, 103 of which were identified as having ADHD and academic problems in reading and/or math. A theoretical model was examined…

A structural equation modelling analysis was used to test the mediating effect of achievement goal factors on the relationship between Egyptian adolescents' perception of parental involvement and academic achievement. The perception of Parental Involvement Scale and Achievement Goal Questionnaire was administered to a sample of 255 first-year…

Predictions about processes linking gender to students' choices of advanced courses were derived from the internal/external frame of reference (I/E) model and expectancy value (EV) theory. The predictions were tested for the domains of mathematics and biology using data from 1,148 students attending academically oriented secondary schools in…

A study was conducted to compare three methods of assessing course-level self-efficacy beliefs within a multitrait multimethod (MTMM) framework. The methods involved: (1) successfully performing a number of domain-related tasks; (2) obtaining specific letter grades in the course; and (3) successfully performing generic academic tasks in the…

The primary objective of this study was to examine the construct validity of two multiple-content testing programs, the multiple-choice Comprehensive Tests of Basic Skills (CTBS/5) and the performance-based Maryland School Performance Assessment Program (MSPAP), by evaluating the true-score longitudinal associations among multiple-content scores…

This report presents evidence that links participation in extracurricular activities (ECAs) in high school with higher SAT Reasoning Test™ (SAT®) scores. Using structural equation models (SEMs) with latent means, we analyzed data from a national sample of college-bound high school students. A series of structural equation models--isolating the…
