Research ethics is considered an important element in academia, concerning the behavior of researchers in promoting scientific integrity. This study aims to survey scientific integrity of researchers in scholarly publishing across 16 global and frontier research universities in Thailand. The quantitative method was used to collect data from researchers through a questionnaire. We received 316 valid responses from researchers. The findings indicate the importance of honesty, transparency, and integrity in reporting findings, as well as the disclosure of conflicts of interest, the ethical responsibilities inherent in research conduct. The results highlight the importance of avoiding duplication and ensuring proper attribution in scholarly publishing to uphold integrity. Ethical citation practices underscore researchers' commitment to maintaining credibility and adhering to ethical standards in academia. The results of the Pearson correlation analysis indicates that there is a linear relationship between six variables (paper submission, ethical process, authorship, plagiarism and self-plagiarism, falsification and fabrication, and conflict of interest) and the researchers' scientific integrity variable. However, there are no notable variations in scientific integrity among different academic roles.
