This study investigates self-rated mental health in terms of psychological problems, protective factors and health-related quality of life (HRQOL) in a nationally representative sample of adolescents (n = 6813) aged 11-17 involved in violence with varying frequency. Using MANCOVA and ANCOVA, youth with single and multiple histories of violent…

Cognitive deficits and particularly deficits in working memory (WM) capacity are common features in neuropsychiatric disorders. Understanding the underlying mechanisms through which WM capacity can be improved is therefore of great importance. Several lines of research indicate that dopamine plays an important role not only in WM function but also…

A number of recent studies suggest that DNA variation in the dopamine transporter gene (DAT1) influences spatial attention asymmetry in clinical populations such as ADHD, but confirmation in non-clinical samples is required. Since non-spatial factors such as attentional load have been shown to influence spatial biases in clinical conditions, here…

Data collection can be the most time- and cost-intensive part of developmental research. This article describes some long-proposed but little-used research designs that have the potential to maximize data quality (reliability and validity) while minimizing research cost. In "planned missing data designs", missing data are used…

Mobile phones and other wireless devices that produce electromagnetic fields (EMF) and pulsed radiofrequency radiation (RFR) are widely documented to cause potentially harmful health impacts that can be detrimental to young people. New epigenetic studies are profiled in this review to account for some neurodevelopmental and neurobehavioral changes…

Objectives/Background: Objectives were to (1) examine previous night's sleep in relation to next day performance on standardized academic achievement and neurocognitive assessments in adolescents, and (2) explore whether previous night's sleep is differentially associated with testing performance for adolescents with and without…

In the neoliberal order, the ideal self is self-responsible, enterprising, flexible and self-centred. Regarding this ideal we argue that the rise of therapisation in society, and in education, particularly, links both the therapeutic and enterprising discourses. The article examines how these discourses jointly produce and legitimate the ideal,…

The neuropsychiatric paradigm has substantial impact on schools. The increase in the number of pupils being diagnosed with attention-deficit/hyperactivity disorder (ADHD) is an expression of the medicalisation of deviance. There is also an increase in educational classes specially designed to meet the needs of children with ADHD. This is contrary…

ADHD is one of the most common psychiatric disorders that appears in childhood and continues through adulthood. It is considered to be a chronic disorder caused by a combination of neurobiological and genetic factors. The children and adolescents who experience this disorder have, along with other symptoms, trouble staying focused, difficulty…

Abstract Elementary school teachers often implement classroom behavioral management systems to address student misbehavior. Common problems targeted by these systems are the inattentive, hyperactive, and impulsive behaviors characteristic of attention-deficit/hyperactivity disorder (ADHD). This study examined teachers' attributions for why…

Background: Children with attention-deficit/hyperactivity disorder (ADHD) experience greater sleep problems than their peers. Although adolescence is generally a developmental period characterized by insufficient sleep, few studies have used a multi-informant, multi-method design, to examine whether sleep differs in adolescents with and without…

The Canadian literature on postsecondary access has identified many of its key determinants including parental education and income, academic performance, and sex. However, relatively little work has investigated the independent role of disability in postsecondary enrollment. This study fills that gap by estimating the relationship between mental…

Many teachers are concerned about their ability to work effectively with students who have a diagnosis of attention deficit/hyperactivity disorder (ADHD). The purpose of this quantitative descriptive study was to determine the perceived efficacy of common interventions used to address negative ADHD behaviors in the elementary and middle school…

This study examined the performance, demographics, and contextual factors of students taking the ACT® test with accommodations compared to students taking the ACT without accommodations. We examined the prevalence of accommodations provided and disability categories as well as performance by disability type. We also examined demographic…

Objective: Studies of healthy individuals and those with cerebellar damage have implicated the cerebellum in a variety of cognitive and behavioral processes. Decreased cerebellar volume has been found in children with attention-deficit/hyperactivity disorder (ADHD) and differentially related to behavioral outcomes. The present study investigated…
