摘　　要：目的:分析儿童早期综合发展的研究现状和主题,为我国儿童早期综合发展的相关研究提供参考。方法:系统检索Web of Science数据库中儿童早期综合发展的相关文献,检索时限为2017年1月1日—2021年12月31日。从时间趋势、期刊分布、国家和机构分布等方面进行文献计量分析。采用潜在狄利克雷分配(LDA)主题模型对纳入文献的主题内容进行挖掘与分析。结果:共纳入891篇文献,发文量整体呈上升趋势,来源出版物共计200种。美国是该领域研究的主要发文国家,发文量占57.688%(514/891)。通过LDA主题模型识别出6个研究主题,进一步归纳为照护者对儿童早期发展的影响、早期教育与儿童早期发展、儿童疾病危险因素与早期识别、儿童早期发展干预的政策与方法4个方面。结论:儿童早期综合发展的研究总体呈上升趋势,通过对相关研究的主题挖掘与分析,有利于进一步为儿童早期综合发展相关研究提供发展方向。Objective To analyze research status and themes of integrated early childhood development,so as to provide a reference for the research of integrated early childhood development.Methods Articles on integrated early childhood development in Web of Science were retrieved systematically.The search time period was from January 1,2017 to December 31,2021.The bibliometric analysis was carried out from the aspects of time trend,journals,countries and institutions distribution and so on.Research topics were mined and analyzed using the Latent Dirichlet Allocation(LDA)topic model.Results A total of 891 articles were included,and the number of articles published in this field showed an growth trend,with a total of 200 source publications.United States was the main publishing country in this field,with 514(57.688%)of the articles issued.Six topics were identified through the LDA topic model,which can be summarized into 4 merged themes,including the impact of caregivers on early childhood development,early education and early childhood development,childhood disease risk factors and early identification,policies and methods of early childhood development intervention.Conclusions The number of articles on integrated early childhood development rises steadily.The topic analysis of the research is conducive to further providing the development direction for the integrated early childhood development.
