多动症患儿的持续反应抑制缺陷与其注意水平、冲动行为的关系

Relationship between persistent response inhibition deficit and attention level/impulsive behavior in childrea with ADHD

目的 研究多动症(ADHD)患儿的持续反应抑制缺陷与注意水平、冲动行为的关系。方法 选择本院儿科2020年1月~2022年5月134例多动症患儿作为研究对象,均行视觉持续性操作测验(CPT)。比较不同视觉CPT错误率患儿的中文版注意缺陷多动症障碍父母评定量表第4版(SNAP-IV)、Conners儿童行为父母问卷。结果 134例患儿中视觉CPT错误率≤10%者35例,11%~30%者64例,>30%者35例。错误率≤10%组的注意缺陷分量表、多动/冲动分量表评分及SNAP-IV总分均显著低于错误率11%~30%组和错误率>30%组,差异有统计学意义(P<0.05)。错误率≤10%组的品行问题、学习问题、心身障碍、冲动-多动、多动指数评分均显著低于错误率11%~30%组和错误率>30%组,差异有统计学意义(P<0.05);三组的焦虑评分无统计学意义的差异(P>0.05)。经Pearson直线相关法分析,多动症患儿的持续反应抑制缺陷与注意水平呈负相关,与冲动行为呈正相关(P<0.05)。结论 多动症患儿的持续反应抑制缺陷越严重,其注意水平越差,冲动行为越明显。

Objective To study the relationship between persistent response inhibition deficit and attention level and impulsive behavior in children with ADHD.Methods A total of 134 children with ADHD from January 2020 to May 2022 in the pediatric department of our hospital were selected as the study subjects,and all of them underwent the visual Continuous Performance Test(CPT).The Chinese version of the attention deficit hyperactivity disorder parental rating scale 4th edition(SNAP-IV)and conners child behavioural parental questionnaire for children with different visual CPT error rates were compared.Results Among the 134 children,the visual CPT error rate was≤10%in 35 cases,11%~30%in 64 cases,and>30%in 35 cases.The attention deficit subscale,hyperactivity/impulsivity subscale score and SNAP-IV total score in the error rate≤10%group were significantly lower than those in the error rate 11%~30%group and the error rate>30%group,and the differences were statistically significant.The scores of conduct problems,learning problems,psychosomatic disorders,impulsivity-hyperactivity,and hyperactivity index scores in the error rate≤10%group were significantly lower than those in the error rate 11~30%group and the error rate>30%group,and the differences were statistically significant(P<0.05).There was no significant difference in anxiety scores among the three groups(P>0.05).According to Pearson linear correlation analysis,the persistent response inhibition deficit in ADHD children was negatively correlated with attention level,and positively correlated with impulsive behavior(P<0.05).Conclusion The more severe the deficit in persistent response inhibition in children with ADHD,the poorer the level of attention and the more pronounced the impulsive behavior.
