随着精神障碍和精神问题发病率的快速上升，精神病学已成为发展最快的临床医学学科之一。该领域的发展重点和研究焦点在不同时期有所演变。
从2001年到2015年，从Web of Science的科学引文索引（SCI）中选取了10种影响因子最高的精神病学杂志的所有文章。使用信息可视化软件Sci2对这些文章进行共词和聚类分析。将文章分为3个时期：2001年 - 2005年、2006年 - 2010年和2011年 - 2015年。每条文献记录包含标题、作者姓名、摘要、关键词、参考文献等信息。
在2001年到2015年的3个时期内，儿童和青少年精神病学、重度抑郁症、精神分裂症和前额叶皮质一直是研究焦点。大脑和荟萃分析逐渐成为新的研究焦点，尽管对症状的研究缓慢减少。分子遗传学也是一个受关注的领域。
利用科学计量学技术将研究焦点可视化可以为我们提供新的思路和研究方法。对精神病学研究焦点和发展趋势进行初步探索的共词分析有助于发现发展规律、选题以及创新性研究。我们的研究存在一些局限性。未来，我们应该扩大研究范围，并使用多种研究方法来丰富我们的研究结果。
Abstract With the rapid increase in the incidence of mental disorders and mental issues, psychiatry has become one of the fastest growing clinical medical disciplines. Development priorities and research foci in this field have evolved over different periods. All the articles in 10 psychiatric journals with the highest impact factors were selected from the Science Citation Index (SCI) in Web of Science from 2001 to 2015. The information visualization software Sci2 was used to conduct co-word and clustering analyses on these articles. The articles were divided into 3 periods: 2001 to 2005, 2006 to 2010, and 2011 to 2015. Each bibliographic record contained a title, author names, abstract, keywords, references, and other information. During the 3 periods between 2001 and 2015, child and adolescent psychiatry, major depression, schizophrenia, and prefrontal cortex were constant research foci. The brain and meta-analysis gradually became new research foci, although research on symptoms slowly decreased. Molecular genetics was also an area of interest. Using scientometrics technology to visualize research foci can provide us with new ideas and research methods. Co-word analysis for the preliminary exploration of research foci and developmental trends in psychiatry is helpful in finding developmental rules, choices of topics, and innovative research. Our study had some limitations. In the future, we should expand our research scope and use a variety of research methods to enrich our results.
