The present longitudinal study aimed to investigate the influence of ADHD symptoms on reading development in elementary schoolchildren. To this end, repeated assessments of ADHD symptoms (teacher ratings of inattention, hyperactivity, and impulsivity) and reading achievement (standardized tests of decoding speed and text comprehension) were…

Objective: To bridge theory of response inhibition and learning in children with ADHD. Method: Thirty ADHD and 30 non-ADHD children (ages 9-12) were compared under concurrent variable interval (VI-15 sec., VI-30 sec. and VI- 45 sec.) reinforcement schedules that required the child to switch between the three schedules under conditions of…

Objective: Compare observed and forecasted efficacy of mixed amphetamine salts extended release (MAS-XR; Adderall) with atomoxetine (Strattera) in ADHD children. Method: The authors analyze data from a randomized, double-blind, multicenter, parallel-group, forced-dose-escalation laboratory school study of children ages 6 to 12 with ADHD combined…

This study examined effects of integrating mindfulness practices into the 5th grade curriculum to improve attention-to-task, including inattention and executive functioning, hyperactivity/impulsivity, and social relations. As academic requirements become more rigorous, students have been expected to demonstrate increased skills in…

We evaluated the evocative effects of four conditions (high- and low-preference activities, low and divided attention) and stimulant medication on the behavior of a 16-year-old boy with attention deficit hyperactivity disorder and moderate mental retardation. All behavior (activity engagement, activity changes, inappropriate touching, rude…

This study investigated "The Journey to Wild Divine" as a biofeedback management tool teaching breathing and relaxation skills to children with Attention-Deficit/Hyperactivity Disorder (AD/HD). The children played the game by manipulating their heart rate using breathing techniques taught in the game, measured through three finger sensors. Parents…

Objective: To test if visual focusing and mimic display as features of self-regulation in ADHD children show a curvilinear relation to rising methylphenidate (MPH) doses. To test if small dose steps of 2.5mg MPH cause significant changes in behavior. And to test the relation of these features to intellectual performance, parents' ratings, and…

The current study replicated the positive effects of performance feedback on treatment integrity and extended previous work by examining reactivity using a multiple baseline design with alternating treatments for observer-present and observer-absent conditions on teachers' implementation of a classwide behavior plan. No differences were found…

Objective: Methylphenidate has four optical isomers due to two asymmetries (erythro-threo and dextro-levo). The initial commercial formulation eliminated the erythro isomer, but the dextro-levo asymmetry was racemic, with equal amounts of d and l-threo isomers (d,l-MPH). Previous work has suggested that the d-threo isomer methylphenidate (d-MPH)…

Objective: To evaluate the long-term tolerability and effectiveness of extended-release mixed amphetamine salts (MAS XR; Adderall XR[R]) in children with attention-deficit/hyperactivity disorder (ADHD). Method: This was a 24-month, multicenter, open-label extension of TWO placebo-controlled studies of MAS XR in children with ADHD aged 6 to 12…

Objective: To examine the effects of methylphenidate on different attentional functions and behavior in children with attention-deficit-hyperactivity disorder (ADHD). Method: A total of 60 ADHD children aged between 8 and 12 years completed a randomized, double-blind, placebo-controlled, within-subject crossover trial with two doses of…

Both teacher and parent delivered consequences have been shown to be effective in improving the classroom behavior of children with Attention Deficit Hyperactivity Disorder (ADHD). However, there is a delay between the behavior and delivery of parent provided consequences. The delay may make the consequences less salient and effective, for…

Objective: To evaluate clinical measures of the benefit/risk ratio in a post hoc analysis of a clinical trial of d-threo-methylphenidate hydrochloride (d-MPH) and d,l-threo-methylphenidate hydrochloride (d,l-MPH). Method: Data from a phase III clinical trial was used to compare equimolar doses of d-MPH and d,l-MPH treatment for…

A study of a 12-year-old boy with attention deficit hyperactivity disorder investigated the effectiveness of a token economy incentive program implemented in the home setting to increase attention to task while doing homework assignments. Results found the boy's percentage of time spent on-task increased markedly. (Author/CR)

Objective: To evaluate the efficacy and safety of dexmethylphenidate hydrochloride (d-MPH, Focalin[TM]) for the treatment of attention-deficit/hyperactivity disorder (ADHD) and to test an a priori hypothesis that d-MPH would have a longer duration of action than d,l-threo-methylphenidate (d,l-MPH). Method: This was a randomized, double-blind study…
