Abstract This research aimed at examining the impact of applying an “Academic Integrity and Scientific Writing" online training program on bio/medical scholars' attitudes, knowledge, and performance toward academic integrity, and scientific writing skills at Mansoura University. Furthermore, the study investigated the relationship between academic integrity, and scientific writing skills before starting the administration of the program and at the end of administrating it. A quasi-experimental pretest-posttest was used. At the start and completion of the ten-week program, participants' self-report attitudes surveys and program tests were examined. At the end of the program, participants were asked to complete a self-evaluation rubric after producing their initial manuscript draft. Descriptive statistics and t-tests showed attitudes, knowledge, and performance of academic integrity, and scientific writing increased significantly. In addition, Pearson's correlation rate analysis proved the connection between academic integrity and scientific writing. Moreover, the effect size of the online program was found to be high. Therefore, this research recommended using academic integrity online program with the integration of scientific writing learning skills to avoid academic misconduct and raise the responsible conduct of research (RCR).
