两种亚型注意缺陷多动障碍儿童在冒险任务中的表现

Performance of Children with Two Subtypes of ADHD in Roger's Risk Task

目的:探讨两种亚型注意缺陷多动障碍患儿(注意缺陷型和混合型)在冒险任务中的表现。方法:选取AD-HD儿童38例,其中注意缺陷型22例,混合型16例,以及在年龄、受教育程度、性别、智力上与ADHD组相匹配的38名正常对照组儿童。采用Roger’s冒险任务进行研究,比较ADHD患儿和正常对照组以及两组ADHD亚型在冒险效应和奖励效应上的选择数量。结果:①在冒险效应上,ADHD患儿冒险性选择的总数量明显高于正常对照组儿童(P<0.05);在奖励效应上,ADHD患儿在各奖励分数类型上的选择成绩高于正常对照组儿童(P<0.05)。②两种亚型ADHD(混合型和注意缺陷型)患儿在冒险效应和奖励效应上选择数量差异无统计学意义(均P>0.05)。结论:两种亚型ADHD患儿均倾向于冒险性行为,两种亚型患儿在冒险任务中表现相似。

Objective： To explore the performance of children with attention deficit hyperactivity disorder（ADHD） in Roger＇s risk task,so as to examine their motivational control function.Methods： Thirty-eight children with clinical diagnosis of ADHD（22 of predominantly inattentive,i.e.,ADHD-I;and 16 of combined,i.e.,ADHD-C） were compared to 38 normal controls who were matched in age,IQ and the years of education in Roger＇s risk task.Results： In the risky effects,ADHD children tended to select more risky behavior than normal controls.In the rewarding effects,ADHD children tended to get more rewarding scores than the normal controls.No significant differences were observed between the two subtypes of ADHD in the risky effects and the rewarding effects.Conclusion： These results support the assumption that ADHD children show motivational deficient in the presence of reward and punishment.
