Nurses engaging in research are held to research ethics standards. Examine experiences, behaviors, and perceptions of nurses in Israel regarding research ethics and explore possible related factors. An original investigator-designed self-administered questionnaire measured five variables: (a) ethics in research, (b) encountered research misconduct during the course of one's studies, (c) the inclination to fabricate data, (d) the inclination to select or omit data, and (e) knowledge of research misconduct in the workplace. Additionally, demographic data were collected. The questionnaire was completed by 151 Israeli registered nurses. 10.2% hold a PhD, 34 % hold an MA, 42.2% hold a BA, and 13.6% with no academic degree. The study was approved by the University's ethics committee; anonymity and consent of the respondents were respected. Registered nurses' level of studies achieved was significantly associated with a lower inclination to fabricate data, with one exception-PhD nurses were more inclined to fabricate data than nurses with a Master's degree. A trend was found in which a higher level of studies is associated with higher knowledge of research misconduct in the workplace. Results indicate that nurses' perceptions of research ethics change throughout their academic studies, indicating a positive influence of level of studies, research experience, and work experience on ethics perceptions. Nevertheless, PhD nurses showed a greater inclination to actually select, omit, or even fabricate data than MA nurses. This may be related to pressure to publish. PhD nursing programs should include ethics training. Academic faculty members should serve as role models regarding research integrity. Research ethics deserves further emphasis on all levels of nurse education in Israel, as well as in the nurses' code of ethics and related documents. This may positively impact ethical research practices.
