Relationship between executive function and social adjustment in children with developmental dyslexia
Objective To explore the characteristics of executive function of developmental dyslexic children and the relation-ship with social adaptability,in order to provide a scientific basis for promoting healthy development of developmental dyslexic chil-dren.Methods From June to September 2023,85 students in the developmental dyslexia group,85 students in the biological age-matched group and 85 students in the reading level-matched group were selected from the third to sixth grades of two elementary school in a region of Xinjiang by cluster random sampling method.Their executive function was assessed by the Stroop procedure,the 2-back procedure and the numerical conversion procedure,respectively,and their social adaptive ability was assessed by the Social Adaptation Scale for Children and Adolescents.An analysis of variance(ANOVA)was used to compare the differences in ex-ecutive function and social adjustment among the three groups,and Pearson's correlation was used to analyze the relationship be-tween executive function and social adjustment in developmental dyslexic children.Results Children in the developmental dyslexia group had lower correctness on the Stroop color-word task(0.72±0.21),the 2-back task(0.32±0.13),the digit-switching task(0.54±0.16)and the total score of social adjustment(165.39±31.36)than children in the biological age-matched(0.80±0.19,0.38±0.11,0.61±0.15,181.71±31.85)and reading level-matched group(0.79±0.17,0.35±0.07,0.58±0.15,175.71±27.48)(F=4.54,5.05,4.97,6.31,P＜0.01).The inhibition(Stroop color-word task correct rate)and conversion subcomponent(digit-switching task correct rate)of the executive function of children in the developmental dyslexia group were both positively correlated with their social adaptive ability(r=0.34,0.43),and the refreshing subcomponent of the executive function(2-back task correct rate)was negatively correlated with their social adaptive ability(r=-0.27)(P＜0.05).Conclusions Children with developmental dyslexia have executive function deficits and social maladjustment,and their executive function is related to social adjustment.Measures should be taken to improve the executive function of developmental dyslexic children and to improve their social adaptation.
