We conducted a systematic review and meta-analysis of anonymous surveys asking scientists whether they ever committed various forms of plagiarism. From May to December 2011 we searched 35 bibliographic databases, five grey literature databases and hand searched nine journals for potentially relevant studies. We included surveys that asked scientists if, in a given recall period, they had committed or knew of a colleague who committed plagiarism, and from each survey extracted the proportion of those who reported at least one case. (...) Studies that focused on academic plagiarism were excluded. Literature searches returned 12,460 titles from which 17 relevant survey studies were identified. Meta-analysis of studies reporting committed and witnessed plagiarism yielded a pooled estimate of, respectively, 1.7 % and 30 %. Basic methodological factors, including sample size, year of survey, delivery method and whether survey questions were explicit rather than indirect made a significant difference on survey results. Even after controlling for these methodological factors, between-study differences in admission rates were significantly above those expected by sampling error alone and remained largely unexplained. Despite several limitations of the data and of this meta-analysis, we draw three robust conclusions: The rate at which scientists report knowing a colleague who committed plagiarism is higher than for data fabrication and falsification; The rate at which scientists report knowing a colleague who committed plagiarism is correlated to that of fabrication and falsification; The rate at which scientists admit having committed either form of misconduct in surveys has declined over time.

The prevalence and characteristics of research misconduct have mainly been studied in highly developed countries. In moderately or poorly developed countries such as Croatia, data on research misconduct are scarce. The primary aim of this study was to determine the rates at which scientists report committing or observing the most serious forms of research misconduct, such as falsification, fabrication, plagiarism, and violation of authorship rules in the Croatian scientific community. Additionally, we sought to determine the degree of development and the (...) extent of implementation of the system for defining and regulating research misconduct in a typical scientific community in Croatia. An anonymous questionnaire was distributed among 1232 Croatian scientists at the University of Rijeka in 2012/2013 and 237 returned the survey. Based on the respondents who admitted having committed research misconduct, 9 admitted to plagiarism, 22 to data falsification, 9 to data fabrication, and 60 respondents admitted to violation of authorship rules. Based on the respondents who admitted having observed research misconduct of fellow scientists, 72 observed plagiarism, 69 observed data falsification, 46 observed data fabrication, and 132 respondents admitted having observed violation of authorship rules. The results of our study indicate that the efficacy of the system for managing research misconduct in Croatia is poor. At the University of Rijeka there is no document dedicated exclusively to research integrity, describing the values that should be fostered by a scientist and clarifying the forms of research misconduct and what constitutes a questionable research practice. Scientists do not trust ethical bodies and the system for defining and regulating research misconduct; therefore the observed cases of research misconduct are rarely reported. Finally, Croatian scientists are not formally educated about responsible conduct of research at any level of their formal education. All mentioned indicate possible reasons for higher rates of research misconduct among Croatian scientists in comparison with scientists in highly developed countries. (shrink)

Academic misconduct is widespread in all cultures, and factors that influence it have been investigated for many years. An act of reporting peers’ misconduct not only identifies and prevents misconduct, but also encourages a student to think and act morally and raises awareness about academic integrity. The aim of this study was to determine factors that prevent students from reporting academic misconduct. A questionnaire to assess views on reporting the academic misconduct of a colleague was developed and sent to all (...) students enrolled at the University of Rijeka, Croatia. Results indicate that a tendency to protect fellow student and to comply with other opinions is the most influential factor that prevents students from reporting peers’ misbehavior. Furthermore, scientific discipline, gender, and age are all significant factors in students’ intention to report peer misconduct. Understanding the factors that influence students’ willingness to report academic misconduct enables faculties, administrators and students to strengthen the ethical culture in the academic community.
