背景：大众媒体如报纸和电视新闻影响心理健康相关的污名。在日本，精神分裂症的名称在2002年被改变，目的是减少耻辱;然而，很少有人知道精神分裂症的名称改变对大众媒体的影响。方法：从日本4家主要报纸和1个电视新闻节目（1985-2013年）的23 169 092篇文章中提取标题和/或文本中包含精神分裂症、抑郁症和糖尿病（DM）新旧名称的文章。包括每个术语的文章数量的轨迹是跨年确定的。然后利用文本数据挖掘技术对新闻标题文本进行词性切分。分词被分为6类，并在每一类提取的词的目标术语和时期也进行了测试。结果：共获得包含目标词的报刊文章51 789篇，电视新闻1106篇。包含目标术语的文章数量逐年增加。2003年以后发表的精神分裂症文章相对于糖尿病文章以及2000 - 2005年发表的抑郁症文章相对增加。2002年前后包含各目标词的文章标题中的词汇使用倾向相当。精神分裂症的文章包含更多的负面词比抑郁症和DM（分别为31.5%，16.0%和8.2%）。结论：精神分裂症名称变更对论文发表影响有限，对其内容影响不大。
Background: Mass media such as newspapers and TV news affect mental health-related stigma. In Japan, the name of schizophrenia was changed in 2002 for the purposes of stigma reduction; however, little has been known about the effect of name change of schizophrenia on mass media. Method: Articles including old and new names of schizophrenia, depressive disorder, and diabetes mellitus (DM) in headlines and/or text were extracted from 23 169 092 articles in 4 major Japanese newspapers and 1 TV news program (1985-2013). The trajectory of the number of articles including each term was determined across years. Then, all text in news headlines was segmented as per part-of-speech level using text data mining. Segmented words were classified into 6 categories and in each category of extracted words by target term and period were also tested. Results: Total 51 789 and 1106 articles including target terms in newspaper articles and TV news segments were obtained, respectively. The number of articles including the target terms increased across years. Relative increase was observed in the articles published on schizophrenia since 2003 compared with those on DM and between 2000 and 2005 compared with those on depressive disorder. Word tendency used in headlines was equivalent before and after 2002 for the articles including each target term. Articles for schizophrenia contained more negative words than depressive disorder and DM (31.5%, 16.0%, and 8.2%, respectively). Conclusions: Name change of schizophrenia had a limited effect on the articles published and little effect on its contents.
