Schizophrenia is a severe mental disorder affecting more than 21 million people worldwide. Scientific collaborations are required to research schizophrenia. However, there have been limited publications to date investigating scientific collaborations in schizophrenia research or reporting individual researchers' achievements(IRA) for authors. This study aimed to investigate the pattern of coauthor collaborations in schizophrenia research. We conducted a bibliometric study of international scientific publications on schizophrenia. About 57,964 abstracts were identified and downloaded from MEDLINE. All were examined using social network analysis (SNA) on February 20, 2018. The clusters of author nationalities, the authors, and the medical subject headings (MESH) terms were presented on Google Maps. A total of 36,934 articles met the inclusion criteria. The mean number of authors per article increased from 4.5 in 2008 to 6.4 in 2017. The proportion of published articles decreased in North America from 46.7% in 2008, to 32.3% in 2017. In contrast, the proportion of published articles in Asia increased from 14.5% in 1998 to 23.9% in 2017. Among the countries generating schizophrenia research the most prominent is China (corr. = 0.98), followed by India (corr. = 0.94), and France (corr. = 0.93). The representative of the biggest cluster is the author Michael F Green from the United States. The top three MESH terms are physiopathology, schizophrenic psychology, and complications. The scientific interest in schizophrenia remains significant. The application of bibliometric indicators of production is evident in the growth of scientific literature on the topic of schizophrenia.
精神分裂症是一种严重的精神障碍，影响着全球超过 2100 万人。需要开展科学合作来研究精神分裂症。然而，迄今为止，针对精神分裂症研究中的科学合作，或报告作者个人的科研成果（IRA），发表的文献有限。本研究旨在调查精神分裂症研究中的合著者合作模式。我们对精神分裂症的国际科学出版物进行了文献计量学研究。从 MEDLINE 中确定并下载了约 57964 篇摘要。所有这些摘要都在 2018 年 2 月 20 日使用社会网络分析（SNA）进行了检查。作者国籍、作者和医学主题词（MESH）术语的聚类显示在谷歌地图上。共有 36934 篇文章符合纳入标准。每篇文章的平均作者数从 2008 年的 4.5 人增加到 2017 年的 6.4 人。北美发表文章的比例从 2008 年的 46.7%下降到 2017 年的 32.3%。相比之下，亚洲发表文章的比例从 1998 年的 14.5%增加到 2017 年的 23.9%。在产生精神分裂症研究的国家中，中国（相关系数=0.98）最为突出，其次是印度（相关系数=0.94）和法国（相关系数=0.93）。最大聚类的代表是来自美国的 Michael F Green 作者。排名前三的 MESH 术语是生理学、精神分裂症心理学和并发症。对精神分裂症的科学兴趣仍然很重要。生产文献计量指标的应用在精神分裂症主题科学文献的增长中显而易见。
