Abstract

BACKGROUND

This study examines changes in the authorship patterns of chairmen of medicine departments from 1979 through 1990, a time when criteria for authorship were widely debated among medical journal editors. Chairmen were selected to be studied because, due to their leadership position and stature, they are likely to "set the example" for many scholars in the academic medicine community.

METHOD

Computerized literature searches were conducted for all 233 persons who were chairmen during at least one year of the 12-year study period (1979-1990) to determine the average number of publications per chairman per year, the average number of coauthors per article published, the location of the chairman on the published list of authors, and other pertinent data required for a thorough analysis of authorship practices. Statistical methods included repeated-measure analysis, sensitivity analyses, and the use of linear models to analyze trends over time.

RESULTS

Among all the chairmen, there was no statistically significant decrease in the average number of articles per year for which the chairmen were last authors, and there was a significant increase in the average number of coauthors per year on published articles. However, factors such as length of chairmanship, frequency of publication, and academic position (i.e., chair, pre-chair, or post-chair) were found to influence patterns of authorship; for example, the 61 individuals who were chairmen for ten years or more had a significant decrease in the number of last-author articles, whereas the 172 individuals who were chairmen for fewer than ten years had a significant increase.

CONCLUSION

Changes in the definition of authorship by medical journal editors did not seem to be important influences on the authorship patterns of the chairmen, since the chairmen did not significantly decrease the number of articles for which they were the last authors, and they significantly increased the number of coauthors of their articles.

摘要

背景

本研究考察了1979年至1990年期间医学系主任的署名模式变化情况，这一时期医学期刊编辑们广泛讨论了署名标准。选择系主任进行研究是因为，由于他们的领导地位和声望，他们很可能为学术医学界的许多学者“树立榜样”。

方法

对在12年研究期（1979 - 1990年）中至少担任过一年系主任的所有233人进行计算机文献检索，以确定每位系主任每年的平均发表论文数量、每篇发表论文的平均合著者数量、系主任在已发表作者名单中的位置，以及对署名实践进行全面分析所需的其他相关数据。统计方法包括重复测量分析、敏感性分析以及使用线性模型来分析随时间的趋势。

结果

在所有系主任中，系主任作为最后作者的每年平均论文数量没有统计学上的显著下降，且发表论文的每年平均合著者数量有显著增加。然而，发现诸如担任系主任的时长、发表频率和学术职位（即系主任、前任系主任或后任系主任）等因素会影响署名模式；例如，担任系主任十年或更长时间的61人作为最后作者的论文数量显著减少，而担任系主任少于十年的172人作为最后作者的论文数量显著增加。
