Scientific misconduct: A cross-sectional study of the perceptions, attitudes and experiences of Spanish researchers.

This study sought to identify the perceptions, attitudes and experiences of Spanish researchers regarding different aspects relating to scientific misconduct, both overall and by gender, years of research experience, and type of research institution. This is a cross-sectional study based on an anonymous online survey, targeting researchers in the field of biomedicine. The survey comprised a first block (13 questions) covering sociodemographic data, and a second block (14 questions) covering researchers' perceptions, attitudes and experiences. A descriptive analysis was performed. 403 researchers answered the survey: 51.1% ( = 205) women, median age 45 years. The observed frequency of scientific misconduct was 78.8%. Additionally, 43.3% of researchers acknowledged having intentionally engaged in some type of scientific misconduct (self-reported frequency). The most frequent type of scientific misconduct was false authorship. The most frequent types of both observed and self-reported scientific misconduct did not appear to differ by years of experience but did differ by gender and type of research institution. In conclusion, there is a high frequency of scientific misconduct among Spanish biomedical science researchers as 4 of 10 researchers recognized that took part in any type of scientific misconduct. There are differences between the most frequent types of misconduct according to different characteristics, mainly type of institution.
