Objective: We performed a 10-year prospective follow-up of a childhood-ascertained (6-12 years), ethnically and socioeconomically diverse sample of girls with attention-deficit/hyperactivity disorder (ADHD; N = 140: combined type [ADHD-C] n = 93; inattentive type [ADHD-I] n = 47) plus a matched comparison group (N = 88). Girls were recruited from…

Objective: This article evaluates the diagnostic utility of a self-report screening tool for adults based on "Diagnostic and Statistical Manual of Mental Disorders" (4th ed.; "DSM-IV") ADHD criteria. Method: Children with speech/language (S/L) impairment and typically developing controls had ADHD symptoms rated by parents and…

Objective: Homework can have beneficial effects for students; however, it presents challenges, particularly for students with attention problems. Although effective homework interventions exist, intervention development and evaluation has been hampered by the lack of psychometrically sound measures. The primary purpose of this study was to…

Fathers, in general, have been underrepresented in studies of parent training outcome for children with attention deficit hyperactivity disorder (ADHD), and the present study aimed to investigate the efficacy of a behavioral parent training program developed expressly for fathers. The present investigation randomly assigned 55 fathers of children…

The study examines the agreement among raters on children's problematic behaviors. A multitrait-multimethod (MTMM) matrix was applied to a normative sample of elementary school-aged children (N = 841). The participants were rated by their physical educators, using the Motor Behavior Checklist for children (MBC; Efstratopoulou, Janssen, &…

This article presents a review of the Children's Organizational Skills Scales (COSS) which were designed to assess how children organize their time, materials, and actions to accomplish important tasks at home and school. The scale quantifies children's skills in organization, time management, and planning (OTMP). The COSS is a multi-informant…

Children with attention deficit/hyperactivity disorder (ADHD) often demonstrate problems in their participation in family occupations, such as household tasks, due to their needs for assistance and their behavior. Because participation in household tasks is part of family life and may be one way that families prepare children for adult roles, it…

Reinforcers contingent on response variability exert powerful and precise control over levels of variability, from stereotypy to stochasticity. This paper reviews how variability-contingent reinforcers interact with non-contingent, eliciting events to influence the variability of operant responses. Relationships to stimulus control, choice,…

Objective: The effect of manipulating item positioning on self-reported ADHD symptoms was examined. We assessed whether listing DSM-IV ADHD symptoms serially or interspersed affected (a) the correlation between ADHD symptoms and (b) the rate of symptom endorsement. Method: In Study 1, an undergraduate sample (n = 102) completed a measure that…

Objective: This study evaluates dexmethylphenidate extended release (d-MPH-ER) in adults with ADHD. Method: Following a 5-week, randomized, controlled, fixed-dose study of d-MPH-ER 20 to 40 mg/d, 170 adults entered a 6-month open-label extension (OLE) to assess long-term safety, with flexible dosing of 20 to 40 mg/d. Exploratory effectiveness…

A double-blind, placebo-controlled, crossover design study was done to evaluate the effects of methylphenidate-osmotic-release oral systems (MPH-OROS) on the organization, time management, and planning (OTMP) of children with attention deficit hyperactivity disorder (ADHD). Results show significant improvements on the OTMP of children with ADHD in…

Data from a national health survey is used to describe the prevalence, demographic correlates, and commorbidities of enuresis in a sample of U.S. children. The 12-month prevalence of enuresis is 4.45 percent and boys have this condition significantly more than girls. A strong association between enuresis and attention deficit hyperactivity…

The aim of the present study was to investigate different neuropsychological impairments and comorbid behavioral problems in relation to symptoms of Attention-Deficit/Hyperactivity Disorder (ADHD), studying the independent effects of different functions as well as specific relations to symptoms of hyperactivity/impulsivity and inattention. A…

The results of the assessment of the accuracy of simple rules based on symptom count for assigning youths to attention deficit hyperactivity disorder subtypes show that having six or more total symptoms and fewer than three hyperactive-impulsive symptoms is an accurate predictor for the latent class sever inattentive subtype.

In recent years, attention-deficit/hyperactivity disorder (ADHD) has become a common pediatric diagnosis. The number of affected children increases with age, most particularly during the years of schooling and academic life, and can cause significant impairment. The nature of this disorder, the challenges of properly diagnosing it, and the…
