注意缺陷多动障碍症状对情绪行为问题的影响:执行功能不同维度的平行中介作用OACSTPCD

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.
