摘要
目的探究学龄前语言障碍儿童的执行功能特征,为早期发现语言障碍儿童的执行功能缺陷及干预提供理论依据。方法收集学龄前语言障碍儿童20例(语言障碍组)与年龄、性别匹配的正常儿童20名(对照组),年龄49.30~71.27个月。使用"梦想"普通话标准化评估工具和中文版学龄前儿童执行功能行为评定量表,对儿童语言能力及执行功能进行测评。采用独立样本t检验分析2组儿童的执行功能差异;用Pearson相关分析语言与执行功能的关系,并用判别分析评估执行功能行为评定量表对语言障碍儿童的识别能力。结果语言障碍组儿童执行功能表现较对照组儿童差,除情感控制因子外,其余因子的差异均有统计学意义(P<0.05)。执行功能与语言能力呈显著正相关(P<0.05);执行功能行为评定量表可正确识别75%的语言障碍儿童。结论学龄前语言障碍儿童不仅有语言功能的损害,也有执行功能缺陷;因此干预措施应兼顾语言和执行功能。
Objective To explore the characteristics of executive function in preschoolers with developmental language disorder(DLD),and provide a theoretical basis for early identification and intervention of DLD.Methods Twenty children with DLD(DLD group)and 20 age-(±3 months)and gender-matched,typically developing children(control group),aged from 49.30 to 71.27 months,were enrolled.Children’s language ability and executive function were evaluated by the diagnostic receptive and expressive assessment of Mandarin and Chinese behavior rating inventory of executive function-preschool version,respectively.T-test was used to analyze the differences in executive function between the groups.Pearson correlation analysis was used to analyze the relationship between language and executive function,and the discriminant analysis was used to evaluate executive function to identify children with DLD.Results Children with DLD performed worse than typically developing children.Except for emotional control scale,the differences of other scales were statistically significant(P<0.05).Language ability was related positively with executive function(P<0.05).Behavior rating inventory of executive function for preschoolers could correctly identify 75%of DLD children.Conclusion Preschoolers with DLD not only have difficulties in language learning,but also in executive function.Therefore,both language and executive function intervention for children with DLD should be taken into account.
