Inhibition, ADHD, and computer games: the inhibitory performance of children with ADHD on computerized tasks and games.

Contrary to empirical reports of inhibitory dysfunction in ADHD, parental reports suggest that when playing computer games, the inhibitory abilities of children with ADHD are unimpaired. This small-scale preliminary investigation into this phenomenon looks at inhibition of an ongoing response and activity exhibited by children with ADHD between 6 and 14 years old on two commercially available games, on the Conners's Continuous Performance Test II (CPT II), and on a more game-like version of the same task that incorporates characteristics commonly found in commercially available computer games. The performance of participants with ADHD on commercially available games is equivalent to that of typically developing participants and is significantly better on the more game-like version of the CPT II.

Play and language in children with autism.

It is well established that the play and language skills of children with autism are impaired. The article considers the relationship between these developments in typically developing children and children with autism. First, the evidence for a relationship between these two areas in typically developing children is reviewed. Despite many methodological differences between studies, this evidence supports a relationship, with specific developments emerging first in play and subsequently in language. Second, evidence for a relationship between play and language in children with autism is reviewed. From published and some previously unpublished data it is concluded that if there is a relationship between play and language in children with autism it is weak, if it exists at all. Finally, the implications of these findings are discussed and it is suggested that any relationship between play and language may be mediated by how children and their parents interact when they are playing.

Estimating pediatric primary care provider visits in a capitated environment: encounter vs. claims databases.

PURPOSE: To evaluate the accuracy of insurance claims data indicating underutilization of primary care visits by children with special health care needs (CSHCN). DESIGN: The study was a retrospective comparison of primary care provider (PCP) utilization by 1,131 CSHCN, using secondary data from electronic claims-and-encounters databases in a Medicaid health maintenance organization (HMO) and a commercial HMO. METHODOLOGY: The study was conducted at the Children's Clinics for Rehabilitative Services (Children's Clinics) in Tucson, Ariz., a provider of specialty care to CSHCN. All the children in the study were eligible for specialty services under Arizona's statewide program for CSHCN and were simultaneously enrolled, from Oct. 1, 1995 through Sept. 30, 1996, in either one or both of the managed care plans for their primary care. Identical PCP-visit information for the same 1-year period was collected from the plans' claims-and-encounters databases, and the number of primary care visits as computed from both databases was compared. PRINCIPAL FINDINGS: Health plan claims data show that only 14 percent of the patients visited a PCP during the course of a year. The encounter data indicate that 59 percent of the same cohort had PCP visits. CONCLUSIONS: Encounter databases capture more information about PCP visits than insurance claims databases in capitated environments.
