Abstract

Dikkat Eksikliği Hiperaktivite Bozukluğu (DEHB), çocuk ve ergenlerde en yaygın nörogelişimsel bozukluklardan biridir ve dikkatsizlik, hiperaktivite ve dürtüsellik gibi çeşitli klinik özellikler gösterir. Bu çalışmanın amacı, DEHB’li çocukların reaksiyon süreleri ile dikkat düzeyleri arasındaki ilişkinin incelenmesidir. Çalışmaya, ilk defa DEHB tanısı almış ve ilaç kullanmayan 37 DEHB’li (9 kız, 28 erkek) çocuk dahil edildi. Çalışmada, çocukların dikkat düzeylerini ve dikkat ile ilişkili diğer semptom şiddetlerini belirleyen Stroop Testi -Temel Bilimler Araştırma Grubu Formu ve d2 Dikkat Testi kullanıldı. Reaksiyon sürelerini ölçmek için Nelson El Reaksiyon Testi uygulandı. Araştırma sonucunda, DEHB’li çocukların reaksiyon süreleri ile Stroop Testi-Test tamamlama süresi arasında pozitif yönde (r=0,453, p=0,005)ve d2 Dikkat Testi işaretleme sayısı (işleme hızı) arasında ise negatif yönde (r=0,465; p=0,004) anlamlı olarak orta düzeyde ilişki olduğu bulundu. Sonuç olarak, DEHB’li çocuklarda, reaksiyon sürelerinde görülen değişikliklerin ve işleme hızlarının mekanizmaları ve altta yatan sebepleri daha iyi şekilde anlaşılmıştır.

INVESTIGATION OF THE RELATIONSHIP BETWEEN REACTION TIME AND ATTENTION LEVELS IN CHILDREN WITH ATTENTION DEFICIT AND HYPERACTIVITY DISORDER

Abstract

Attention Deficit Hyperactivity Disorder (ADHD) is one of the most common neurodevelopmental disorders in children and adolescents, exhibiting various clinical features such as inattention, hyperactivity, and impulsivity. The aim of this study is to investigate the relationship between reaction times and attention levels in children with ADHD. The study included 37 children with ADHD (9 girls, 28 boys) who were newly diagnosed and not taking medication. The Stroop Test and the d2 Attention Test were used to determine the children's attention levels and other related symptom severities. The Nelson Hand Reaction Test was administered to measure reaction times. The results of present study were showed a moderate positive correlation between reaction times of children with ADHD and Stroop Test completion time (r=0.453, p=0.005), and a negative correlation with the number of marks (processing speed) in the d2 Attention Test (r=0.465; p=0.004). In conclusion, the mechanisms, and underlying causes of changes in reaction times and processing speeds in children with ADHD have been better understood.
