Attention-deficit/hyperactivity disorder (ADHD) is the most common neurobehavioral disorder of childhood and can profoundly affect the academic achievement, well-being, and social interactions of children; the American Academy of Pediatrics first published clinical recommendations for the diagnosis and evaluation of ADHD in children in 2000; recommendations(More)
This research tested the hypothesis that in hyperactive children a low dose of methylphenidate (0.3 mg/kg) would produce scores superior to those with a high dose (1.0 mg/kg) or placebo on the matching familiar figures test (MFF), a primary index of impulsivity. The hypothesis was based on an earlier finding that the highest percentage of correct responses(More)
We studied 45 patients who had autonomic failure with computed tomography, magnetic resonance imaging and positron emission tomography with [18F]fluorodeoxyglucose to characterize the neuroimaging features of multiple system atrophy and pure autonomic failure and determine the utility of these techniques in distinguishing multiple system atrophy from pure(More)
OBJECTIVE Numerous investigations have examined the efficacy of pharmacological treatment for attention-deficit/hyperactivity disorder (ADHD) in children. However, relatively few studies have addressed the impact of treatment on long-term subjective, psychosocial outcomes, such as health-related quality of life (HRQL). This study examines the long-term(More)
OBJECTIVE To examine the adjustment of children of mothers with both active and nonactive breast cancers in comparison with a healthy community control sample. METHODS Participants included 80 mothers and their children. Half of the mothers had breast cancer or a history of breast cancer. Children in both groups ranged in age from 8 to 19 years.(More)

As the official record of an academically young field, issue by issue the Journal demonstrates that pediatric psychology is maturing into a most productive field. It has been an honor to edit the Journal. I will(More)
We compared magnetic resonance imaging (MRI), magnetic resonance angiography, and transcranial Doppler ultrasonography as predictors of specific neurocognitive functions in children with sickle cell disease. Participants were 27 children with sickle cell anemia (hemoglobin SS) who were participants in the Stroke Prevention Trial in Sickle Cell Anemia (STOP)(More)
The authors have used generalised Galois Theory to construct a homotopy double groupoid of a surjective fibration of Kan simplicial sets. Here we apply this to construct a new homotopy double groupoid of a map of spaces, which includes constructions by others of a 2-groupoid, cat 1-group or crossed module. An advantage of our construction is that the double(More)
To determine if mothers of aggressive boys have the same propensity as their sons to infer hostile intentions in ambiguous interpersonal situations, 50 mothers of aggressive and nonaggressive boys were each asked to interpret hypothetical situations involving themselves with their child, their partner, and a peer as well as hypothetical situations involving(More)
