【摘要】：自闭谱系障碍(ASD)的研究已经有70余年的历史,近年来国际社会对自闭谱系障碍的研究热情空前高涨,呈现出多学科交叉融合的态势。明晰自闭谱系障碍研究的历史脉络,了解国际学界对自闭谱系障碍的研究现状,深刻认识和把握国际自闭谱系障碍研究的主流趋势显得尤为重要。知识图谱是近年来新兴的研究方法,在图书情报学、医学、计量学等多个学科得到广泛的应用,在一定程度上弥补了传统研究方法无法满足迅速发展的科学研究的弊端。本研究利用词频分析、共词分析、引文分析、共被引分析、聚类分析等理论和技术,借助VOSviewer和CiteSpace等信息可视化软件,绘制国际自闭谱系障碍研究领域的科学知识图谱,直观形象地展示了该领域研究的总体分布、知识基础、研究前沿和热点主题等内容。首先,对国际自闭谱系障碍研究从总体上进行描述分析。在美国Web of Science核心合集的两个数据库(SCI-E、SSCI)收集到与自闭谱系障碍相关数据样本27327条,其年度发文呈指数增长趋势,已发表文献的主要类型为期刊文章(Article)、文献的语言种类以英语为主,Web of Science学科类别集中于发展心理学。其次,对国际自闭谱系障碍研究的地域分布和合作关系进行了研究。地域分布呈现出明显的马太效应,自闭谱系障碍研究地域分布集中在欧美。美国是发文最多的国家,加利福尼亚大学洛杉矶分校是发文最多的机构;运用VOSviewer绘制国家、机构合作网络,美国、英国、加拿大与诸多国家开展了广泛的合作,地域相近性和学科相似性是机构合作的重要影响因素。然后,使用CiteSpace软件绘制国际自闭谱系障碍研究文献共被引知识图谱,从大量文献中快速、准确地发现领域的知识基础和研究前沿,根据聚类结果对知识基础进行深入的讨论。本研究发现国际自闭谱系障碍领域研究的知识基础集中在ASD相关筛查和诊断量表,在不同时间段内,知识基础内容有所差异。本研究也结合了中介中心性的指标分析了转折点文献。运用CiteSpace软件特有的Citation Burst功能对研究前沿进行探测,发现该领域有大量能够代表研究前沿的文献。最后,运用VOSviewer软件对国际自闭谱系障碍的研究主题分布及演变进行了分析。通过词频分析了解领域的主题分布。通过主题叠加视图展示主题的发展变化趋势。结果发现当前ASD领域的热点主题集中在心理、脑与神经、社会性发展/干预、教育以及社会问题五个方面。通过以上分析,对研究结果进行总结,指出本研究的不足,并对未来的研究进行展望。
[Abstract]:The study of autistic pedigree disorder (ASD) has a history of more than 70 years. In recent years, the international community has an unprecedented enthusiasm for the study of autistic pedigree disorders, showing a trend of multidisciplinary cross-integration.It is very important to understand the historical context of autistic pedigree disorders, to understand the current research situation of autistic pedigree disorders in international academic circles, and to have a deep understanding and grasp of the mainstream trend of international autistic pedigree disorders research.Knowledge map is a new research method in recent years. It has been widely used in many subjects such as library and information science, medicine, metrology and so on. To a certain extent, it has made up for the shortcomings of traditional research methods which can not satisfy the rapid development of scientific research.Based on the theories and techniques of word frequency analysis, co-word analysis, citation analysis, cocitation analysis, cluster analysis and other information visualization software, such as VOSviewer and CiteSpace, this study draws a map of scientific knowledge in the research field of autistic spectrum disorders.The general distribution, knowledge base, research frontier and hot topic of this field are displayed intuitively and vividly.First of all, the study of international autistic pedigree disorders is described and analyzed as a whole.A total of 27327 data samples related to autistic spectrum disorders were collected in two databases of the core collection of Web of Science in the United States, and their annual publications showed an exponential growth trend.The main type of published literature is the journal article "Article", and the language category of the literature is mainly English web of Science discipline, which is mainly focused on developmental psychology.Secondly, the regional distribution and cooperative relationship of international autistic pedigree disorders are studied.The study of autistic pedigree disorders is concentrated in Europe and America.The United States is the country that issues the most papers, and the University of California, Los Angeles, is the organization that sends the most papers. The United States, the United Kingdom and Canada have extensively cooperated with many countries by using VOSviewer to draw countries, institutional cooperation networks, the United States, the United Kingdom, Canada and many other countries.Geographical proximity and discipline similarity are important factors influencing institutional cooperation.Then, we use CiteSpace software to map the citation knowledge of the international autocline spectrum disorders, quickly and accurately find the knowledge base and research frontier from a large number of documents, and discuss the knowledge base according to the clustering results.This study found that the knowledge base in the field of autistic disorders is focused on the ASD screening and diagnosis scale, and the content of the knowledge base is different in different time periods.This study also analyzes the turning point literature with the index of intermediary centrality.By using the special Citation Burst function of CiteSpace software to detect the research frontier, it is found that there are a lot of documents in this field which can represent the research frontier.Finally, the distribution and evolution of the international autistic spectrum disorders are analyzed by using VOSviewer software.Through word frequency analysis to understand the topic distribution of the field.The theme overlay view is used to show the trend of theme development.The results showed that the current hot topics in the field of ASD focused on five aspects: psychology, brain and nerve, social development / intervention, education and social problems.Through the above analysis, the research results are summarized, the shortcomings of this study are pointed out, and the future research is prospected.
