基于CiteSpace的近五年国内外创伤后应激障碍研究可视化分析

Cite Space-based visualization analysis of domestic and foreign researches on post-traumatic stress disorder in recent five years

目的 了解近五年国内外创伤后应激障碍(PTSD)的研究现状,了解该领域研究的前沿和热点。方法 检索Web of Science和中国知网(CNKI)数据库,检索时限为2017年1月1日-2021年12月31日。运用Excel和CiteSpace对纳入的8 505篇文献的数量、作者、国家、机构和关键词等进行可视化分析。结果 (1)近五年,国内外PTSD相关文献发文量均呈增长趋势;(2)国外文献中,发文数量排名前5位的国家分别为美国、英国、中国、澳大利亚和加拿大,其中加拿大中心性最高(0.18);(3)国内外研究机构均以高校为主;(4)国外文献发文量前三位的学者是Bryant RA、Ressler KJ、Greenberg N,国内前三位分别为伍新春、李越峰、严兴科和张桂青(二者并列),与国外作者相比,我国学者发文量总体较少;(5)研究关键词方面,国内外关注均较多的是PTSD和抑郁。结论 近五年,PTSD一直是国内外研究的热点,国内外研究均关注PTSD与抑郁症。加强国际交流,有助于推动PTSD相关研究的进步。

Objective To understand the research status of post-traumatic stress disorder(PTSD) at home and abroad in recent five years, and to grasp the research frontiers and hot spots in this field.Methods Two electronic databases, Web of Science and China National Knowledge Infrastructure(CNKI), were retrieved for the literature published from January 1, 2017 to December 31, 2021. A total of 8 505 literatures were included, then the visualization analysis of the number of publications, authors, countries, institutions and keywords was conducted based on Microsoft Excel and CiteSpace software.Results(1) The number of publications in domestic and foreign showed an increasing trend in recent five years.(2) In foreign literature, the top five countries in terms of the number of publications were the United States, the United Kingdom, China, Australia and Canada, with Canada having the highest centrality(0. 18).(3) Both domestic and foreign research institutions were dominated by universities.(4) In terms of the number of articles published, the top three foreign scholars were Bryant RA, Ressler KJ and Greenberg N, and the top three Chinese scholars were Wu Xinchun, Li Yuefeng, Yan Xingke and Zhang Guiqing(tied for the third place). Compared with foreign authors, the number of articles published by Chinese scholars was relatively small.(5) In terms of research keywords, PTSD and depression were of more concern in both domestic and foreign.Conclusion In recent five years, PTSD has been a hot topic at home and abroad, with both domestic and international studies focusing on PTSD and depression, and strengthening international exchanges may help promote progress in the field of PTSD research.
