The interpersonal (e.g., manipulative, deceitful) and affective (e.g., callous, unemotional) features associated with adult psychopathy have been identified in children and adolescents. Although early research suggests that these features have clinical utility in identifying a particularly severe and recalcitrant form of antisocial behavior with…

We report the results of a test of a structural model reflecting the longitudinal relationships of psychosocial problems among youths involved in a Center for Substance Abuse Treatment funded clinical trial for juveniles that participated in a diversion program. The project is evaluating the efficacy of an intensive 16-week case management service…

Macro-level data paint a detailed picture of the vulnerability of young people in employment, such as their concentration in casualised jobs, low average-weekly earnings and reduced access to collective representation, yet little is known about the internal conflicts that arise in individual workplaces that employ youth. This study seeks to…

Background: We aimed to describe similarities and differences in the developmental course of psychopathology between children with and without intellectual disabilities (ID). Methods: Multilevel growth curve analysis was used to analyse the developmental course of psychopathology, using the Child Behavior Checklist (CBCL), in two longitudinal…

Students have problems in their lives, but can teachers help them? Should teachers help? The No Child Left Behind (NCLB) act and its emphasis on standardized test results have forced school systems to produce high scores, and in turn school administrators pressure teachers to prepare students for taking standardized tests. Teachers may want to…

The present study investigated to what extent the members of adolescents' peer groups share similar educational expectations, and to what extent overall and school-related adjustment are associated with these expectations. Three hundred and ninety-four ninth-graders facing the transition to secondary education filled in questionnaires measuring…

Changing perspectives on mathematics teaching and learning resulted in a new generation of mathematics textbooks, stressing among others the importance of mathematical reasoning and problem-solving skills and their application to real-life situations. The article reports a study that investigates to what extent the reform-based ideas underlying…

The author examined the potential influence of learning opportunities provided in 1 U.S. and 1 Chinese mathematics textbook series on students' problem-solving performance. Also, the author studied learning opportunities provided in the textbooks by analyzing word problem distribution across various problem types, as well as the potential…

Universal screening is a critical prerequisite to providing early school-based prevention and intervention services for students at risk for or with academic, behavioral, or emotional difficulties. Although use of academic and behavioral screening has become more prevalent, criteria for making informed decisions about appropriate screening tools…

In "Holding Accountability to Account: How Scholarship and Experience in Other Fields Inform Exploration of Performance Incentives in Education"--a paper presented at the National Center on Performance Incentives research to policy conference in February--Richard Rothstein, a research associate at the Economic Policy Institute, argues educational…

The influence of cognitive growth in working memory (WM) on mathematical problem solution accuracy was examined in elementary school children (N = 353) at risk and not at risk for serious math problem solving difficulties. A battery of tests was administered that assessed problem solving, achievement, and cognitive processing (WM, inhibition,…

Presented at the quarterly meeting of the New York Area SAS Users-Group in December 2008. In virtually any research context, there is likely to be opportunity to apply mixed-models--of which repeated-measures, multilevel, hierarchical and random- and fixed-effect models are specific types-- that improve upon their traditional linear or generalized…

This study used latent profile modeling (LPA) with a community sample that included an enriched sampling of children (aged 6-11) diagnosed with attention deficit/hyperactivity disorder (ADHD) (N=271). Six classes of ADHD emerged from our LPA; only 17% of children fell into a class without significant co-occurring symptoms. In addition, nearly half…

Children with autism and other disabilities frequently do not eat a variety of foods, eating only a few very specific foods. Additionally, many children are extremely resistant to trying different foods and attempts to introduce new foods often result in problem behaviors. This can have serious health implications for some children, as the foods…

The concepts of self-determination and self-advocacy have been a focus in the education of students with disabilities and many new curricula, guidelines, and materials have recently become available for educators. This article describes a project that involved individuals with intellectual disabilities in making a movie as a strategy for exploring…
