Objective: To investigate the influence of home nurture environment on language development and social emotion in children with developmental language disorder (DLD).
Methods: The 1-3 Years Child Home Nurture Environment Scale, Gesell Developmental Scale, and Infant-Toddler Social and Emotional Assessment Scale were used for the evaluation of 125 children with DLD. A total of 130 children with normal language development matched for age and sex were enrolled as control group.
Results: Compared with the control group, the DLD group had a significantly higher proportion of children in a bad home nurture environment and significantly lower scores of all domains of home nurture environment (P<0.05). In children with DLD, the home nurture environment score was positively correlated with the level of language development (r=0.536, P<0.01) and the score of ability domain in social emotion (r=0.397, P<0.01) and was negatively correlated with the scores of the domains of explicit behavior, covert behavior, and imbalance in social emotion (r=-0.455, -0.438, and -0.390 respectively, P<0.01). Home nurture environment had direct influence on language development in children with DLD and affected their language development via the mediating effect of social emotion.
Conclusions: Home nurture environment influences language development and social emotion in children with DLD, and social emotion has a partial mediating effect between home nurture environment and language development.
目的: 探讨家庭养育环境对发育性语言障碍（DLD）儿童语言发育和社会情绪的影响。
方法: 采用1~3岁儿童家庭养育环境量表、Gesell发育诊断量表和1~3岁幼儿情绪及社会性发展量表对125例DLD儿童进行测评。130例年龄、性别匹配的语言发育正常的儿童作为对照组。
结果: DLD组儿童的家庭养育环境中不良环境所占比例显著高于对照组，家庭养育环境中的各领域得分均显著低于对照组（P < 0.05）。DLD儿童的家庭养育环境得分与儿童的语言发育水平（r=0.536，P < 0.01）、社会情绪中的能力域得分（r=0.397，P < 0.01）呈正相关，与社会情绪中的外显行为域、内隐行为域、失调域得分呈负相关（r分别为-0.455、-0.438、-0.390，P < 0.01）。DLD儿童的家庭养育环境对儿童的语言发育水平有直接的影响，也通过社会情绪的中介效应影响儿童的语言发育水平。
结论: 家庭养育环境影响DLD儿童的语言发育和社会情绪；社会情绪在儿童家庭养育环境和语言发育中起部分中介效用。
