Since Kahlbaum's classic 19th-century description of catatonia, our conceptualization of this syndrome, as well treatment options for it, has advanced considerably. However, little is known about the current state of the catatonia literature since a comprehensive bibliometric analysis of it has not yet been undertaken.
The purpose of this study was to conduct a bibliometric analysis, along with a content analysis of articles reporting new findings, to better understand the catatonia literature and how catatonia research is changing.
Using the search term "Title(catatoni∗)" in Web of Science Core Collection for all available years (1965-2020), all available publications (articles, proceeding papers, reviews) pertaining directly to catatonia were identified, and metadata extracted. Semantic and coauthorship network analyses were conducted. A content analysis was also conducted on all available case reports, case series, and research articles written in English.
A total of 1015 articles were identified representing 2861 authors, 346 journals, and 15,639 references. The average number of publications per year over the last 20 years (31.3) more than doubled in comparison to that in the 20 years prior (12.8). The top 3 most common journals were Psychosomatics/Journal of the Academy of Consultation-Liaison Psychiatry, Journal of ECT, and Schizophrenia Research, which represented 12.6% of all publications. Content analysis revealed that catatonia articles are increasingly published in nonpsychiatric journals. There was a notable paucity of clinical trials throughout the study period. Since 2003, articles on catatonia secondary to a general medical condition, as well as articles including child/adolescent patients and patients with autism spectrum disorder or intellectual disability, have made up increasing shares of the literature, with a smaller proportion of articles reporting periodic or recurrent catatonia. We noted a decrease in the proportion of articles detailing animal/in vitro studies, genetic/heredity studies, and clinical trials, along with stagnation in the proportion of neuroimaging studies.
The catatonia literature is growing through contributions from authors and institutions across multiple countries. However, recent growth has largely been driven by increased case reports, with significant downturns observed in both clinical and basic science research articles. A dearth of clinical trials evaluating potential treatments remain a critical gap in the catatonia literature.
自 19 世纪卡尔鲍姆（Kahlbaum）对紧张症进行经典描述以来，我们对该综合征的概念化以及治疗选择已经有了很大的进步。然而，由于尚未对紧张症文献进行全面的文献计量学分析，因此对其现状知之甚少。
本研究的目的是进行文献计量分析，并对报告新发现的文章进行内容分析，以更好地了解紧张症文献以及紧张症研究的变化。
使用 Web of Science 核心合集的搜索词“Title(catatoni∗)”搜索所有可用年份（1965-2020 年）的所有可用出版物（文章、会议录论文、综述），直接与紧张症相关，并提取元数据。进行语义和合著网络分析。还对所有可用的英文病例报告、病例系列和研究文章进行了内容分析。
共确定了 1015 篇文章，涉及 2861 位作者、346 种期刊和 15639 条参考文献。过去 20 年（31.3）每年发表的论文数量是前 20 年（12.8）的两倍多。最常见的 3 种期刊是精神医学/联络精神病学学会杂志、电抽搐治疗杂志和精神分裂症研究，占所有出版物的 12.6%。内容分析表明，紧张症文章越来越多地发表在非精神病学期刊上。整个研究期间都明显缺乏临床试验。自 2003 年以来，关于由一般医疗状况引起的紧张症的文章，以及包括儿童/青少年患者和自闭症谱系障碍或智力残疾患者的文章，在文献中所占的比例不断增加，而周期性或复发性紧张症的文章比例较小。我们注意到，详细描述动物/体外研究、遗传/遗传研究和临床试验的文章比例下降，神经影像学研究的比例停滞不前。
紧张症文献的增长得益于来自多个国家的作者和机构的贡献。然而，最近的增长主要是由增加的病例报告驱动的，临床和基础科学研究文章都出现了大幅下降。缺乏评估潜在治疗方法的临床试验仍然是紧张症文献中的一个关键空白。
