摘要
目的 探讨执行功能的两个维度——行为管理指数(BRI)和元认知指数(MI)在注意缺陷/多动障碍(ADHD)症状与儿童情绪行为问题之间的中介作用.方法 选择符合美国精神障碍诊断与统计手册第 5 版(DSM-5)诊断标准的 102 名 6～12 岁 ADHD儿童为研究对象,使用自编一般情况调查表、中文版斯诺佩评估量表第 4 版(SNAP-Ⅳ)-父母版、执行功能行为评定量表(BRIEF)-父母版、长处和困难问卷(SDQ)-父母版进行调查,并进行平行中介效应分析.结果 注意缺陷、多动-冲动、BRI、MI及情绪行为问题相互间呈正相关(r=0.409～0.934,P<0.001).注意缺陷症状正向预测BRI、MI及情绪行为问题(β=1.459、1.114、0.294,均P<0.01),BRI和MI正向预测情绪行为问题(β=0.224、0.080,均P<0.05),即BRI和MI在注意缺陷与情绪行为问题之间起平行中介作用,中介效应占总效应的 58.73%.多动-冲动症状正向预测BRI、MI及情绪行为问题(β=1.071、2.057、0.223,均P<0.05),BRI正向预测情绪行为问题(β=0.333,P<0.001),MI对情绪行为问题的预测作用无统计学意义(β=0.026,P>0.05),即BRI在多动-冲动症状与情绪行为问题间起部分中介作用,其中介效应占总效应的 64.72%.结论 ADHD儿童BRI和MI在症状和情绪行为问题间起中介作用.
Abstract
Objective To explore the mediating role of behavioral regulation index(BRI)and metacognition index(MI),two dimensions of executive function,in the relationship between attention deficit hyperactivity disorder(ADHD)symptoms and children's emotional behavioral problems.Methods A total of 102 children with ADHD aged 6-12 years old who met the Diagnostic and Statistical Manual of Mental Disorders 5th edition(DSM-5)criteria were selected as the study subjects.They were investigated with the self-made general situation questionnaire,the Chinese version of the Swanson Nolan and Pelham,version Ⅳ for ADHD(SNAP-Ⅳ)-parent form,Behavior Rating Inventory of Executive Function(BRIEF)-parent form,and parent edition of Strengths and Difficulties Questionnaire(SDQ).Parallel mediating effect was analyzed.Results Positive correlations were found among attention deficit,hyperactivity-impulsivity,BRI,MI,and emotional behavioral problems,respectively(r=0.409-0.934,all P<0.001).Attention deficit positively predicted BRI,MI and emotional behavioral problems(β=1.459,1.114,0.294,all P<0.01).BRI and MI positively predicted emotional behavioral problems(β=0.224,β=0.080,both P<0.05),suggesting that behavioral regulation index and metacognition index played a partial mediating role between attention deficit and emotional behavioral problems,and the mediating effect accounted for 58.73%of the total effect.Hyperactive-impulsivity positively predicted BRI,MI and emotional behavioral problems(β=1.071,2.057,0.223,all P<0.05),BRI positively predicted emotional behavioral problems(β=0.333,P<0.001),but MI did not predict emotional behavioral problems(β=0.026,P>0.05),indicating that only behavioral management played a partial mediating role between hyperactive-impulsivity and emotional behavioral problems.The mediating effect accounted for 64.72%of the total effect.Conclusion BRI and MI play a mediating role between emotional behavioral problems and symptoms in ADHD children.
