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 investigate the performance of adolescents with attention deficit hyperactivity disorder (ADHD) in two subtypes of ADHD. Methods: Thirty-eight children with AD-HD were selected, including 22 cases of attention-deficient type and 16 cases of mixed type. Thirty-eight children in normal control group were matched with ADHD group in age, education level, gender and intelligence. Roger’s adventurous task was used to study the number of options for risk-taking and reward effects in children with ADHD and controls, as well as ADHD subtypes in both groups. Results: ①In the risk-taking effect, the total number of adventurous children with ADHD was significantly higher than that of the normal control group (P <0.05). In the reward effect, children with ADHD had higher scores of choice scores Control group children (P <0.05). ② There was no significant difference in the number of risk-taking effects and rewarding effects between children with both subtypes of ADHD (mixed and atypical) (P> 0.05). CONCLUSIONS: Both subtypes of children with ADHD tended to be adventurous, with both subtypes showing similar behaviors in adventurous tasks.
