No analysis of redundant or duplicate publications, deemed unethical and unscientific, has been undertaken in psychiatric literature.
To analyze the proportion and patterns of redundant publications associated with index articles published in two major Indian psychiatry journals.
Index articles were original papers published in the and the between 2015 and 2017. Using a systematic search strategy that combined author names and article keywords, we combed the literature to identify and characterize redundant publications related to these index articles. Redundant publications were classified into one of the following categories using definitions: dual, suspected dual, salami slicing, meat extender, and extended sample publication.
From 324 index articles screened, a total of 27 articles (8.4%) were identified to have 32 associated redundant publications of the following types: dual ( = 3), suspected dual ( = 2), salami slicing ( = 22), meat extender ( = 3), and extended sample publication ( = 2). A majority of the redundant articles ( = 23, 71.9%) failed to clearly cross-reference the prior publication(s). We also identified nine non-redundant but related publications with no proper cross-referencing in five of them.
Redundant publications are a common practice in the psychiatry journals screened. Salami slicing is the most common form of redundancy, with no proper cross-referencing in most cases. Concerted efforts are needed to detect and deal with this concerning practice that undermines both science and ethics.
在精神医学文献中，尚未对被视为不道德和不科学的冗余或重复出版物进行分析。
分析与印度两大精神医学期刊发表的索引文章相关的冗余出版物的比例和模式。
索引文章为2015年至2017年在[期刊名1]和[期刊名2]上发表的原创论文。我们采用结合作者姓名和文章关键词的系统检索策略，梳理文献以识别和描述与这些索引文章相关的冗余出版物。根据[具体]定义，将冗余出版物分为以下类别之一：双重发表、疑似双重发表、切香肠式发表、添肉式发表和扩大样本发表。
在筛选的324篇索引文章中，共确定27篇文章（8.4%）有32篇相关的以下类型的冗余出版物：双重发表（n = 3）、疑似双重发表（n = 2）、切香肠式发表（n = 22）、添肉式发表（n = 3）和扩大样本发表（n = 2）。大多数冗余文章（n = 23，71.9%）未能清楚地交叉引用先前的出版物。我们还识别出9篇非冗余但相关的出版物，其中5篇没有适当的交叉引用。
在筛选的精神医学期刊中，冗余出版物是一种常见现象。切香肠式发表是最常见的冗余形式，大多数情况下没有适当的交叉引用。需要共同努力来发现和处理这种破坏科学和伦理的令人担忧的做法。
