This study examines the experiences, current situations, and educational needs of researchers in life sciences in order to develop an educational program for research ethics. A total of 267 subjects from medical center C participated in this study. The findings were as follows: 1) 43.8% of respondents agreed with the item, “I have included the name of a person in my research who didn’t contribute to my research,” while only 3.7% agreed with the statement “I have tried to minimize risk factors which could impact on participants during the research process”; 2) on the status of ethics education, the number of discussions or lectures regarding research ethics and ethical problems was very low; 3) the highest acknowledged educational need was for “scientists’ ethical responsibility and attitudes” (69.7%), while the lowest acknowledged need was for a “peer review system” (27.0%); 4) differences in educational needs were found among the different disciplines. In medical science, research misconduct, human and animal research ethics, conflict of interest, and peer review were highlighted, while in basic biological science, animal research ethics and the relationships among research members were emphasized. In nursing science, ethics education on authorship and referencing was widely regarded as lacking. These findings indicate that research ethics education is needed in order to support responsible research conduct.
