Comparison of Response Inhibition and Sustained Attention in ADHD and SCT Children: Distinct Contribution of ADHD and SCT to Attention Problems Based on Cold and Hot Executive Circuits
Recent studies have identified a disorder called Sluggish Cognitive Tempo (SCT) that has similarities with attention deficit/hyperactivity disorder (ADHD) in attention problems, and often mistakenly labeled as ADHD. The purpose of this study was to compare response inhibition and sustained attention in children with ADHD and SCT in order to elucidate the distinct contribution of attention problems in these two disorders.
The design of the present study was in the frame of Casual Comparative. Participants comprised 100 boys (50 ADHD and 50 SCT) from elementary schools in Tabriz in 2019-2020 academic years, who were selected through a screening method using the Child Behavior Rating (SNAP-IV) and SCT scale. So then, continuous performance test was performed on the samples to measure response inhibition and sustained attention. For data analysis, Manova and SPSS 20 were used.
The results showed a significant difference between the two groups in response inhibition and sustained attention (P<0.0001). Moreover, ANOVA and means of the two groups showed that children with ADHD have deficits in response inhibition and children with SCT have deficits in sustained attention.
Based on the research background and the findings of this study, it seems that children with SCT have deficits in hot executive circuit and children with ADHD have trouble in cold executive circuit.
