Research has assumed a crucial part in the advancement and development of restorative sciences. In this period of proof-based prescription, distribution of refreshed writing is viable to patient care and to further major discoveries in the field of medicine. Research is not only vital to medicine but also to a number of other fields. However, it’s unfortunate that basic ethics of research are sometimes bypassed. Plagiarism has been prevalent,1 particularly due to easy access available to several original studies via the internet.2 Defined as the practice of taking someone else’s work or ideas and passing them off as one’s own,3,4 plagiarism is a serious offence due to the negation of contributions of original writers, it has proven to be severely problematic.5,6

Recently, a number of studies have been published on research ethics but those are mostly from the developed part of the world where research ethics are taught at the undergraduate level. In comparison, the research output on research ethics focusing especially on plagiarism from developing countries including Pakistan is low.7 Ghias’s survey5 on general disregard of research ethics in Pakistani medical students reported a high frequency of medical students involved in copying work from online published sources, seniors, class fellows with or without their permission, fabrication of data to present desirable outputs, forging professors’ signatures, faking health certificates, etc.

Although plagiarism detection software is advancing8,9 and there has been an increase in the number of plagiarized papers being recognized and withdrawn from the journals, there is a lack of awareness about their existence.10 A clear absence of accentuation by establishments featuring the issue has been cited as one of the significant explanations behind widespread plagiarism.7

Plagiarism is not only repeatedly opted by medical peers11 but also other professional students. However, no such research has been conducted highlighting this fact and establishing a comparison between medical and non-medical students of this misconduct. The purpose of this study was to fill that gap in the assessment of plagiarism and explore the attitudes towards plagiarism amongst medical students and compare it with students from other professional branches including engineering, arts, commerce, etc.

METHODS

In January-February 2017, we received an approval from the Institutional review board of Dow University of Health Sciences to conduct an eight-week cross-sectional study for the assessment of the knowledge and attitudes of Undergraduate students in Karachi, Pakistan towards plagiarism in researches. With a confidence level of 95% and an outcome factor frequency of 50%, a sample size of 384 was calculated. Using convenience sampling, we interviewed 412 students. Considering that 18 (4.3%) out of 412 interviewees refused to take part in the study and a further 7 (1.6%) left the questionnaires incomplete which were thus discarded, the cooperation rate came out to be 94.1%.

All undergraduate students of Karachi irrespective of their fields of study were allowed to participate. Since all participants of our study were 18 years old or above, written consent was taken only after ensuring the anonymity of their identities and confidentiality of their responses. Age and socioeconomic restrictions such as household income and enrollment in public/private sector universities were not placed. The only restrictions placed were academic status which should be undergraduate and city of residence which had to be Karachi. The questionnaire was developed according to the objective and design of our study by an equal contribution from all the authors. It consisted of 28 questions and was divided into three parts. The first part focused on the knowledge of the interviewees about plagiarism in researches and included questions regarding awareness of research ethics, the term plagiarism and the different tools used to detect plagiarism. Two scenario-based questions12 were also included for better assessment of the knowledge as shown in Table 1. One was plagiarized while the other was not. The second and the third section of the questionnaire involved attitude and practice-related questions respectively. Attitudes were assessed using questions related to the personal views of students towards the importance of plagiarism-proof writing and the punishments associated with cases of non-compliance. Practice-related questions considered the reasons of plagiarizing, if done in the past, together with the measures taken to eradicate plagiarism, if any.

Author's version: I believe that certain advances in polymer synthesis, electronics and micro/nanofabrication, contact lens sensors can be produced to quantify the concentrations of many biomolecules in ocular fluids.

All the authors collected data using a pre-coded questionnaire by conducting face-to-face interviews. Certain measures were taken to avoid possible biases. The interviewers avoided engaging in mundane conversations, had prepared explanations of the questions and set a time for the participants. This aimed at reducing interviewer and instruction bias. Response bias was reduced by ensured anonymity. The time frame for the practice questions was 1 year which minimized recall bias. Using Statistical Package for the Social Sciences (SPSSver. 23; IBM, Armonk, NY, USA), χ-2 test was applied to compare the responses of medical and non-medical students to find possible statistical correlations.

RESULTS

A total of 385 students, enrolled in medical and non-medical universities completed the questionnaire, out of which 145 (37.7%) were males and 240(62.3%) were females. 206(53.4%) students were enrolled in medical universities while 179 (46.4%) belonged to non-medical universities. The mean age of the students was 21.1 ± 1.8. Students enrolled in medical universities belonged to Dow University of Health Sciences (168 students), Jinnah Sindh Medical University (16 students), Karachi Medical and Dental College (6 students), and Ziauddin University Hospital (11 students), among which 191 students were enrolled in MBBS program, 8 students in BDS program and 7 students were doing Doctor of Pharmacy. Students enrolled in non-medical universities belonged to Karachi University (73 students), NED University (61 students), Institute of Business Administration (36 students), Iqra University (10 students), and Tabani’s School of Accountancy (4 students), among which 64 students were enrolled in BBA program, 29 students in Arts, 49 students in engineering, 17 students in Computer Science, 4 in Chartered Accountancy, and 16 in Law program.

A vast majority of individuals (n=288, 74.6%) were aware of research ethics and had heard about the term plagiarism (n=353, 91.5%). Majority of individuals (n=335, 86.8%) were aware of the term “referencing” and knew its importance. More than two-thirds of the individuals identified the authentic ie, not plagiarized paragraph (n=262, 67.9%), and plagiarized paragraph (n=267, 69.2%).

An overwhelming majority of individuals (n=365, 94.6%) considered it important to discuss issues like plagiarism in research ethics. Almost half of the individuals (n=180, 48.6%) believed that self-plagiarism was plagiarism and more than one-third (n=136, 35.5%) believed that they work in plagiarism-free environments. Almost one-third of the individuals (n=125, 32.4%) held the opinion that plagiarism could be justified by short deadlines, and 154 (39.9%) felt tempted to commit plagiarism because everyone else was doing it. Almost all the individuals (n=332, 86%) thought plagiarism could be avoided and 303 (78.5%) believed that authors who plagiarize deserve punishment. 271 (70.2%) individuals supposed that beginners in the field of research should be forgiven for plagiarism since they’re at the early stage of learning, while a majority (n=342, 88.6%) considered plagiarism as stealing.

More than half of the individuals (n=235, 60.9%) had experience with researches. Almost half of them (n=186, 48.2%) plagiarized unintentionally due to lack of knowledge and learned about it later. Majority (n=238, 61.7%) considered checking their articles for plagiarism before sending it to a journal. More than one-third of the individuals (n=138, 35.8%) used freely available online tools to detect plagiarism in their research papers, 150 (38.9%) used to get their articles reviewed for plagiarism by the review board of your institute before sending it to a journal. Only 91 (23.6%) plagiarized because their institute did not have a plagiarism policy, and 238 (61.7%) copied a friend’s or a colleague’s work with his permission.

χ-2 tests were conducted and knowledge of, attitude towards, and practices regarding research ethics and plagiarism of medical students were compared with those of non-medical students. Medical students were more aware of the research ethics than non-medical students (P=0.001). Majority of the medical students identified the authentic paragraph and plagiarized paragraph (P=0.005, and P<0.001, respectively). When the attitudes were compared, significantly more medical students considered it important to discuss issues like plagiarism in research ethics than non-medical students (P=0.011) and did not believe that plagiarism is justified for short deadlines (P<0.001). Non-medical students felt tempted to plagiarize because everyone else was doing it more than medical students (P<0.001), and a majority of medical students considered plagiarism as stealing (*P<*0.001). Furthermore, statistically significant differences were also found when comparing the practices of medical and non-medical students. More medical students had experience with research than non-medical students (*P=*0.003). Significantly more non-medical students plagiarized unintentionally due to lack of knowledge and learnt about it later than medical students (P<0.001). However, more non-medical students used online plagiarism detection tools to check plagiarism in their papers (P<0.001) and get their articles reviewed for plagiarism by the review board of their institute before sending it to a journal (P=0.036). Statistically, a significant difference was found to exist between the groups when they were asked if they had ever plagiarized because their institute did not have a plagiarism policy (P<0.001). More non-medical students had copied a friend’s or a colleague’s work with his permission than non-medical students (P<0.001). The comparative results with their significant differences have been shown in Table 3.

DISCUSSION

Our principal finding was that a majority of the participants had significant knowledge of the term plagiarism and the importance of referencing and considered its discussion vital in research ethics. These results are inconsistent with another study conducted in Pakistan which indicated a significant lack of the knowledge of referencing and plagiarism among students and faculty members of medical colleges.7 Similarly, another study on dental and medical professionals in India reports the lack of knowledge and awareness in this regard.13 A similar majority of the participants in our study had prior experience with researches and preferred checking their articles for plagiarism by using freely available online tools before sending it to a journal. Thus with research experience, the chances of an author publishing plagiarized work is reduced. Consistent with this finding, plagiarism is reported quite frequently in the early stages of a researcher’s career14 whereas relatively fewer studies report such incidences in students of higher grades with more research experience.15 Furthermore, the study by Shirazi et al (2010)7 discussed herein also revealed a better understanding of self-plagiarism among faculty members in contrast to medical students due to differences in prior research experiences.

The participants’ knowledge in our study was assessed with two sample paragraphs; one of which was plagiarized and the other was not. Even with the strong belief of an overwhelming majority of the interviewees that plagiarism is avoidable, some of them (especially the ones in their early stages of learning) still plagiarized unintentionally as was also seen in the study,16 while others justified it with the lack of an institutional review policy and considered it for short deadlines. Undeveloped authorial identity is speculated as a major cause of unintentional plagiarism.16 Considering review procedures for plagiarism cumbersome and a difficult task for the institutions, instructional interventions were developed for individuals; the beneficial effects of which in terms of knowledge to avoid plagiarism were reported in the study conducted on the students of London.16 Since most of the individuals in our study considered plagiarism as stealing, as reported in a previous research conducted in Saudi Arabia,17 they deemed it as a punishable offence. However, they still believed that beginners in the field of research should be given some leverage in this aspect.

Secondly, we found statistically significant differences in knowledge, attitudes, and practices between medical and non-medical students with medical students having more knowledge about research ethics and plagiarism. Thus, a majority of them could differentiate the plagiarized sample paragraph from the authentic one. A similar study with a slight difference in the choice of the subjects was conducted in Karachi, Pakistan by Shirazi et al in 2010, in which they compared the knowledge of medical students and faculty members and concluded little difference between the two groups.7 Rathore et al reported positive attitudes of the medical students towards plagiarism in their study conducted in Lahore, Pakistan in 2015.18 In this study, we found statistically significant differences between the attitudes and practices of medical and non-medical students towards plagiarism with a generally negative attitude among medical students towards the act of plagiarism, possibly as a result of greater experience in the field. Thus, significant emphasis was laid on the detailed discussion of plagiarism in research ethics. This coupled with the fact that a significant majority of these students considered plagiarism as stealing and did not justify plagiarism in case of short deadlines, meant that reported temptation to plagiarize was essentially lower than that analyzed in the other group. As an outcome, non-medical students were comparatively more inclined towards the practice of plagiarism with or without a reasonable explanation for doing so. These differences in attitudes between medical and non-medical students can perhaps be attributed to additional multiple factors. Firstly, medical students are more likely to be aware of both, the importance of ethics, due to medical schools focusing on bio-ethics to improve patient care, and the importance of research, as there is strong encouragement from faculty in medical schools.19,20 Secondly, the curriculum of medical schools in Pakistan has a specific focus on teaching research methodology which is bound to improve knowledge and hence, attitudes towards ethical practices.21 Thirdly, physicians in Pakistan are mostly under public employment and to advance through the ranks, a certain number of publications are required; therefore they are more likely to work with medical students enforcing better attitudes towards research ethics. Finally, there are dedicated private institutions which teach medical students how to conduct research properly such the Research Council of Pakistan, such institutions do not exist for other fields.

Our study has certain limitations which need to be considered. Since our study is based solely on undergraduate students in well-reputed universities of Karachi, accurate assessment of overall existent knowledge and attitudes towards plagiarism could not be made. This is because all the participants essentially belonged to the same age group and socioeconomic status with seemingly easier access to plagiarism detection tools. Also due to convenience sampling, students currently at the same academic level were assessed and professionally qualified researchers could not be included in our study hence, our population lacked diversity. We have reported only one aspect of research ethical misconducts that is plagiarism while there exist many others, which even though less prevalent, are still important to discuss and take care of. Some of these aspects include falsification, fabrication, misrepresentation, breach of confidentiality, etc.

Having said that, efforts should be taken to promote research on this topic with alterations in the interviewees’ age and academic statuses so that diverse perspectives could be gathered about the knowledge and prevalence of plagiarism. The population under consideration should include different demographic groups such as people from socioeconomic backgrounds and institutes other than those already considered especially focusing on the researchers who have no knowledge or access to plagiarism detection software. However, the comparisons between the medical and non-medical students drawn in this study should also be extended further for additional insight into the possible reasons of differences in attitudes and practices between the two groups. Research department officials in colleges should be separately assessed to see if advanced learning and easier access to different research tools have had an impact on their attitude towards plagiarism. Since research ethics constitute a separate discipline which studies the norms and serves the aim of a research, these are vital, as adherence to these promote values that give rise to collaborative work which ultimately affects the success of a research. Thus, the prevalence of ethical misconducts of a study other than plagiarism should also be analyzed in further studies. Also, interviewee’s opinion regarding the avoidance of plagiarism and other elements of ethical misconducts should be considered.

CONCLUSIONS

This study aimed at determining the knowledge, attitudes, and practices of an undergraduate student towards plagiarism, shows that a huge majority of individuals had proper knowledge of the terms plagiarism and referencing and realized their importance. This gave rise to a significantly negative attitude towards plagiarism in this group as shown by the approach considered towards researchers who plagiarize. However, the practice of plagiarism was prevalent in these individuals when they did not have the knowledge about research ethics which gives us the idea that majority of the researchers currently practicing plagiarism might be doing so because of the lack of knowledge. Further studies should assess this association which if proven true must be followed by an academic strategy aimed at raising proper awareness in researchers. Also, it was observed that medical and non-medical students had considerable differences in their opinions with medical students having a negative attitude towards plagiarism owing to their greater knowledge and experience with researches. Since academic integrity is important in making students more ethical in their profession, institutions must come together to generate a culture of integrity for the correction of student behaviors, especially, concerning ethical misconducts. Furthermore, institutions should provide their students with resources to screen their manuscripts for plagiarism before sending it to a journal. Emphasis on research ethics should be laid on in the undergraduate medical school curriculum which might decrease deliberate plagiarism. This shall contribute to more authentic and less questionable publications from the students.
