Comparison of Inhibition in School-Aged Children with Conduct Disorder and Normal Group

Inhibition is an important component of Executive functions which has been postulated as one of important Neuro Psychological correlates (or even causal) of Conduct Disorder. Different researches have reported inconsistent findings of executive function deficits in children with conduct disorder. The purpose of this study was to compare inhibition in children with conduct disorder and normal group. Using CSI-4 and Raven test, 38 children (19 boys as conduct disorder group and 19 boys as comparable group) aged 8 to 11 years, were selected. Using Continuous Performance Test and GO-NO/GO Test, inhibition was compared in two groups. The results indicated that two groups did not have significant difference in commission error which is an indicator of inhibition but they have significant difference in reaction time. The present study showed that children with Conduct Disorder without concurrent Attention Deficit Hyperactive Disorder, compared with normal group, have no deficits in inhibition and inhibition deficits, probability are not the central impairment in conduct disorder.
