ABSTRACT
OBJECTICES AND METHODS:
The purpose of this study was to examine availabilities of stop-signal task as a screening test for ADHD and as a research tool. Stop-signal task was applied to 40 ADHD patients and 18 normal children. Followings are the results of this study.RESULTS:
There were significant differences between ADHD group and control group in ZRFT, mean delay x block and primary-RT of stop-signal task performance(p<0.05). There was no significant difference in results of continuous performance test. SSRT of stop-signal task had significant correlation with hit reaction time of continuous performance test, and primary-RT and primary-SD with attentiveness and hit reaction time of continuous performance test. There was no significant correlation between scores of ADDES-HV and stop-signal task performance. In change of primary-SD according to intelligence, primary-SD decreased as intelligence increased but made plateau after IQ 110, and in change of SSRT according to age, SSRT decreased as intelligence increased but made plateau after 10 year-old. In discriminant ability, mean delay x block and primary-RT showed highest discriminant ability (each 75%). In addition P-inhibit showed 63.89%, SSRT showed 58%, ZRFT showed 67%, and primary-SD showed 58% in discriminant ability. There was no significant difference in stop-signal task performance between ADHD with hyperactivity and ADHD without hyperactivity.CONCLUSION:
In this point of view, stop-signal task was proved to be a useful research tool for attention deficit hyperactivity disorder as well as useful screening test tool.
