Abstract: Objective To study the characteristics of parent-child interaction in children with developmental language disorder (DLD), and to analyze the influencing factors of DLD, so as to provide basis for early clinical detection and early intervention. Methods Thirty children with DLD diagnosed in the Child Health Care Clinic of Cheeloo Hospital of Shandong University were selected into this study from January 2018 to March 2020. Meanwhile, 30 normal children who took physical examination in the Child Healthcare Clinic of Cheeloo Hospital of Shandong University and the Child Healthcare Clinic of Shandong University Central Campus Hospital were selected as control. The Chinese version of the Parent-Child Interaction Assessment Scale and video analysis were used to assess the interactive behaviors of the children and their caregivers. Results There was significant difference in the scores of parent-child interaction between the DLD group and the control group (t=4.548, P<0.05). Multivariate regression analysis showed that the higher the scores of autonomy and social emotion of parent-child interaction, the higher the risk of DLD (OR=5.935, 8.833,P<0.05); While the higher the scores of empathy, respect for autonomy and the cultivation of cognitive ability in parent-child interaction, the lower the risk of DLD (OR=0.165, 0.417, 0.202, P<0.05). Higher education level of mothers (OR=0.159, 95%CI: 0.031 - 0.805), better family rearing environment (OR=0.051, 0.140) and family annual income>10⁵ yuan (OR=0.013, 95%CI: 0.033 - 0.380) were protective factors for DLD, while the daily video time＞1 h/d (OR=21.605, 95% CI: 3.214 - 145.225) was a risk factor for DLD in children. Conclusions In community primary medical institutions, children with DLD can be identified early with the help of parent-child interaction, so as to get chance for early screening and intervention. Improving family rearing environment and reducing screen time may reduce the occurrence of children's language disorder.

摘要： 目的 研究发育性语言障碍(DLD)儿童亲子互动的特征以及影响因素,为临床早期发现、早期干预提供依据。方法 选取2018年1月-2020年3月在山东大学齐鲁医院儿童保健门诊就医,经专业医师确诊的DLD儿童30例,另选取同时期在山东大学齐鲁医院儿童保健门诊及山东大学中心校区校医院儿童保健门诊进行健康查体的正常儿童30例为对照组。利用中文版亲子互动评估量表,采用录像分析的方式对纳入研究的儿童和其养育者的互动行为进行分析。结果 DLD组亲子互动得分低于对照组,差异有统计学意义(t=4.548,P<0.05)。多因素回归分析结果显示:亲子互动的自主性和社会情感得分越高,DLD的发生风险越高(OR=5.935、8.833,P＜0.05);亲子互动的共情、对自主性的尊重、认知能力的培养维度得分越高,DLD的发生风险越低(OR=0.165、0.417、0.202,P＜0.05);母亲受教育程度高(OR=0.159,95%CI:0.031~0.805)、家庭养育环境好(OR=0.051、0.140)、家庭年收入>10万(OR=0.113,95%CI:0.033~0.380)是DLD的保护性因素;每日视屏时间>1 h(OR=21.605,95%CI:3.214~145.225)是DLD的危险性因素。结论 社区基层医疗机构儿童保健工作中,可借助亲子互动早期识别有DLD倾向的儿童,为早期筛查和干预赢得时间。日常生活中,改善家庭养育环境、减少儿童视屏时间可降低儿童语言障碍的发生。
