The purpose of present study is to examine the differences of impulsivity between Attention-Deficit/Hyperactivity Disorder(ADHD) and Conduct Disorder(CD). The subjects of this study consist of four groups. ADHD patients(N=12) were sampled from psychiatry patients. CD group(N=17) and ADHD+CD comorbidity group (N=12) were sampled from a juvenile reformatory. Middle school students who were volunteer were assigned to Normal Control(NC) group(N=12). ADHD group, CD group, and ADHD+CD group were diagnosed using DSM-IV criteria. Four groups took the Intelligence test, executive function tests and MMPI. The results are as follows. Four groups had no difference in IQ. But ADHD and ADHD+CD group were significantly impaired on executive function measures compared with CD and NC group. CD group and ADHD+_CD group showed higher scores in MMPI 4(Pd) scale compared with ADHD and NC group. While CD group showed an average score in F scale, ADHD and ADHD+CD group did show high score in the same scale. This study suggests that impulsivity of ADHD reflects not impulsive personality trait but symptoms related to neuropsychological impairments. And it seems that impulsivity of CD reflects impulsive personality trait. While CD group showed ego-syntonic attitude toward their impulsivity, ADHD and ADHD+CD group show ego-dystonic attitude toward their impulsive problems. This study suggests that although ADHD and CD group show similar behavioral problems, different therapeutic approaches should be taken.
