Abstract
This study aimed to explore the gap between attitudes towards and personally observed breaches of research integrity among medical postgraduates in China, a critical yet understudied population. We conducted an online, cross-sectional survey among postgraduates at three Chinese medical schools. A self-administered questionnaire was used to evaluate their attitudes toward research integrity breaches and their perceptions of such behaviors among peers. Among 983 respondents (719 master's, 264 doctoral), a strong majority condemned serious research misconduct. Only 0.93% expressed acceptance for falsifying images to reverse results, and 1.53% for manipulating data to achieve significance. However, peer-reports revealed a higher prevalence of observed misconduct, with 18.41% indicating knowledge of data fabrication among peers. In conclusion, while Chinese medical postgraduates largely condemn serious research misconduct, the peer-reported occurrence of such behaviors indicates that ethical awareness has not been fully translated into practice. These findings highlight the need for bolstered educational initiatives and suggest that the peer-report method can be a key tool for educators to assess and address integrity issues within their institutions.
