Abstract

PURPOSE

To investigate the determinants of fraud in medical imaging research.

METHOD

This study analyzed aggregated survey data on scientific integrity completed by 877 corresponding authors who published in imaging journals in 2021. Multivariate regression analyses were performed to determine the association of scientific fraud with the following variables: survey participants' age (<18, 18-24, 25-34, 35-44, 45-54, 55-64, or > 65 years), gender (male, female, or other), Corruption Perceptions Index (CPI) of their country of work (linear 0-100 scale), academic degree (medical doctor or other), academic position (none, fellow/resident, instructor/ lecturer, assistant professor, associate professor, full professor, or other), and years of research experience (<5, 5-10, or > 10 years).

RESULTS

Thirty-seven survey participants (4.2%) indicated they had committed scientific fraud in the past 5 years, and 223 (25.4%) indicated they had witnessed or suspected scientific fraud by departmental colleagues in the past 5 years. Instructors/lecturers were significantly more likely (P = 0.029) and fellows/residents were nearly significantly more likely (P = 0.050) to have committed scientific fraud, with odds ratios (ORs) of 4.954 and 5.156, respectively (Nagelkerke R of 0.114). Survey participants > 65 years of age and survey participants working in less corrupt countries were significantly less likely (P = 0.022 and P = 0.044, respectively) to have witnessed or suspected scientific fraud committed by their departmental colleagues, with ORs of 0.412 and 0.988 (per unit increase in CPI), respectively (Nagelkerke R of 0.064).

CONCLUSIONS

Fraud in medical imaging research appears to be more common among junior faculty and in more corrupt countries.

摘要

目的

调查医学影像学研究中欺诈行为的决定因素。

方法

本研究分析了 2021 年在影像学期刊上发表文章的 877 位通讯作者完成的关于科学诚信的综合调查数据。采用多元回归分析方法，确定科学欺诈与以下变量的关联：调查参与者的年龄（<18、18-24、25-34、35-44、45-54、55-64 或>65 岁）、性别（男、女或其他）、工作所在国家的腐败感知指数（CPI）（线性 0-100 范围）、学历（医学博士或其他）、学术职位（无、研究员/住院医师、讲师/助理教授、副教授、教授或其他）和研究经验年限（<5、5-10 或>10 年）。

结果

37 位调查参与者（4.2%）表示在过去 5 年内曾有过科学欺诈行为，223 位（25.4%）表示在过去 5 年内曾目睹或怀疑过部门同事的科学欺诈行为。讲师/助理教授更有可能（P=0.029），研究员/住院医师也几乎更有可能（P=0.050）从事科学欺诈行为，优势比（OR）分别为 4.954 和 5.156（Nagelkerke R 的 0.114）。年龄>65 岁和在腐败程度较低的国家工作的调查参与者，目睹或怀疑其部门同事从事科学欺诈行为的可能性显著较低（P=0.022 和 P=0.044），OR 分别为 0.412 和 0.988（CPI 每增加一个单位）（Nagelkerke R 的 0.064）。
