This study aims to determine the relationship among factors affecting research misconduct within the research system of medical sciences in Iran. Using phenomenography, the perceptions of individuals involved in the activities of macro, meso, and micro levels of the research system were investigated and 13 affecting factors were identified. The DEMATEL method revealed complicated and intertwined relationships among these factors based on the experts' judgment. Most of the macro and meso factors were in the cause group and most of the micro factors were in the effect group. The results showed that critical factors such as "Monitoring and dealing with research misconduct," "Transparency in research," "Management of journals" and "Ethical considerations in the publication of research results" escalate research misconduct. The study indicated that track the relationship among factors in the research system can provide the opportunity to explain research misconduct on a transitional path from macro to micro level.
