This research investigated whether delayed school entry was associated with higher achievement in national tests of reading and numeracy in Grades 3, 5, 7, and 9 (n = 2,823). Delayed entry was related to advantages in reading (0.14 SD) and numeracy (0.08 SD) at Grade 3, although little variance was explained (1%-2%). This slight advantage…

This study examined the contribution of cochlear implants (CIs) to the social-emotional functioning of children who are deaf or hard of hearing (dhh). Sixty-three parents of children who are dhh participated in the study. Thirty children were CI users and 32 used hearing aids (HAs). They completed the Strengths and Difficulties Questionnaire and a…

Background: DSM-IV specifies three ADHD subtypes; the combined, the hyperactive-impulsive and the inattentive. Little is known about the developmental relationships underlying these subtypes. The objective of this study was to describe the development of parent-reported hyperactivity-impulsivity and inattention symptoms from childhood to…

Relatively little is known about the factor structure of disruptive behavior among preadolescent girls. The present study reports on exploratory and confirmatory factor analyses of disruptive girl behavior over four successive data waves as rated by parents and teachers in a large, representative community sample of girls (N = 2,451). Five factors…

Inattentive-hyperactive and oppositional behavior have been hypothesized to be developmental precursors to conduct problems. We tested these hypotheses using a longitudinal sample of 6,466 offspring of women selected from nationally representative US households. Conduct problems across 8-13 years were robustly predicted by conduct problems at 4-7…

Objective: Developmental and subtype differences in behavioral assets and problems were examined in 318 children newly diagnosed with ADHD. Method: Three age groups were compared: 4 to 6.9 years (n = 95), 7 to 9.9 years (n = 136), and 10 to 15 years (n = 87); with two subtypes examined: inattentive (n = 151), and hyperactive/combined (n = 167).…

This study extends previous research by examining whether maternal inattention, impulsivity, and hyperactivity are associated with different parenting behaviors. Ninety-six mother-son dyads participated in the study, and the boys ranged between 4 and 8 years of age. Maternal inattention was uniquely and positively associated with mothers' use of…

Sustained attention to visual and auditory stimuli and reflection-impulsivity were examined in 48 hyperactive and 48 normal 9 and 14 year old boys. Multivariate analyses, followed by univariate tests, indicated that the nonhyperactive Ss increased sustained attention efficiency with age to both visual and auditory Stimuli. Hyperactive Ss increased…

Performance on tasks of memory and of attention was consistently interrelated for nonlearning disabled children and less consistently so for learning disabled subjects. Hyperactivity was also related to poorer performance on the cognitive measures. (Author/DB)
