Objective: Unresolved questions exist concerning diagnosis of ADHD. First, some studies suggest a potential overdiagnosis. Second, compared with the male-female ratio in the general population (3:1), many more boys receive ADHD treatment compared with girls (6-9:1). We hypothesized that this occurs because therapists do not adhere to "Diagnostic…

It is almost self-evident that test results will be unreliable and misleading if those undergoing assessments do not make a full effort on testing. Nevertheless, objective tests of effort have not typically been used with young adults to determine whether test results are valid or not. Because of the potential economic and/or recreational benefits…

Little empirical evidence exists regarding the developmental links between childhood psychopathology and borderline personality disorder (BPD) in adolescence. The current study addresses this gap by examining symptoms of attention deficit hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD) as potential precursors. ADHD and BPD…

Reflective of interest in mental health and substance abuse issues among youths involved with the justice system, we performed a latent class analysis on baseline information collected on 100 youths involved in two diversion programs. Results identified two groups of youths: Group 1: a majority of the youths, who had high levels of delinquency,…

This article reviews our understanding of reading disorders in children and relates it to current proposals for their classification in DSM-5. There are two different, commonly occurring, forms of reading disorder in children which arise from different underlying language difficulties. Dyslexia (as defined in DSM-5), or decoding difficulty, refers…

ADHD is associated with academic underachievement, but it remains unclear what mechanism accounts for this association. Semantic language is an underexplored mechanism that provides a developmental explanation for this association. The present study will examine whether semantic language deficits explain the association between ADHD and reading…

This study investigated the perceptions of children with Attention-Deficit/Hyperactivity Disorder (ADHD) of their ADHD symptoms in terms of the positive illusory bias (PIB), their attributions for their problem behaviors, and their beliefs about whether their problem behaviors and disorder are stigmatizing. Participants were 152 9- to 14-year-old…

Working memory (WM) is considered a core deficit in Attention-Deficit/Hyperactivity Disorder (ADHD), with numerous studies demonstrating impaired WM among children with ADHD. We tested the degree to which WM in children with ADHD was improved by performance-based incentives, an analog of behavioral intervention. In two studies, WM performance was…

Purpose: The purpose of this study was to explore whether parents of CWS reported the presence of ADHD symptoms that would warrant a referral to a psychologist to rule out the disorder. This study also aimed to describe the characteristics of the sample in terms of gender, family history of stuttering, presence of neurological impairment,…

Background: There is increasing interest in the experiences and well-being of siblings growing up with a brother or sister with a disability in Australia. However, research to date has primarily obtained parent reports of sibling adjustment and mental health. Therefore, the aim of the current study was threefold: (1) to report on the mental health…

Objective: Evaluation of the efficacy of a patented, compound herbal preparation (CHP) in improving attention, cognition, and impulse control in children with ADHD. Method: Design: A randomized, double-blind, placebo-controlled trial. Setting: University-affiliated tertiary medical center. Participants: 120 children newly diagnosed with ADHD,…

More and more research is showing that excessive sugars, dyes, preservatives, and possibly even milk and wheat products can affect activity level, attention, interactions, confidence, and sense of well being, all factors that impact a child's ability to learn. A child cannot be asked to make healthy food choices while the rest of the family makes…

The history of ADHD is in part a history of children who have not fitted in at school. Yet until recently, surges in diagnostic levels had not prompted a questioning of the school's complicity in the trend. Through an analysis of the Diagnostic and Statistical Manual for Mental Disorders (DSM), the principal diagnostic guideline relating to ADHD,…

Methods of identifying poor test-related motivation using the Wechsler Adult Intelligence Scale Digit Span subtest are based on identification of performance patterns that are implausible if the test taker is investing full effort. No studies to date, however, have examined the specificity of such measures, particularly when evaluating persons…

Objective: To determine if sensory overresponsivity (SOR) is a moderating condition impacting the activity of the Hypothalamic Pituitary Adrenal (HPA) Axis in children with ADHD. Method: Participants were children with (n = 24) and without ADHD (n = 24). Children in the ADHD group were divided into SOR (ADHDs) and non-SOR (ADHDt) groups using the…
