Diagnosis of ADHD among gifted children in relation to KEDI-WISC and TOVA performance

The following study was conducted to evaluate the correlation between intelligence and a Continuous Performance Test (CPT) that assesses. Attention Deficit Hyperactivity Disorder (ADHD) in children. Characteristics of attention in gifted children with ADHD were also investigated. A sample of 177 elementary school students was studied, and their attention was measured with the Test of Variables of Attention (T.O.V.A.). About 9.4% of the gifted children were identified with ADHD using the T.O.V.A.) About 9.4% of the gifted children were identified with ADHD using the T.O.V.A., Child Behavior Check List (CBCL) and Teacher's Report Form (TRF). Significant positive correlations were found between intelligence (KEDI-WISC) and omission error, commision error, and response time (RT) variability on the T.O.V.A. That is, children with a high level of intelligence made fewer omission and commision errors and responded more consistently on the T.O.V.A. than children with lower intelligence. No significant correlation was found between intelligence and response time. Overall, gifted children performed better on the T.O.V.A. than nongifted children. Specifically, with the exception of response time variably, gifted children with ADHD performed better on tasks of omission error, commission error, and response sensitivity than nongifted children with ADHD. Further discussions are suggested based on the results mentioned above.
