Introduction
Development and progress of human society is rely on research and the application of its principles in educational-scientific fields. Research is one of the most important tasks of universities in order to find and provide solutions to solve problems and obstacles in the society. Students play an important role in research and production of scientific documents, and this is the reason why universities have moved from education only, which is known as first-generation universities, to second-generation universities or education combined with research. Student research committees in the second generation universities play a vital role in the development of research, they identify interested students by establishing a relationship between faculty members and students, creating friendly research groups, research camps and show them the way. Which may be a kind of research talent search. Due to the importance of the mentioned cases, it is necessary to investigate the knowledge, attitude, and performance of students towards research in medical sciences universities. Because the first stage is the formation of research beliefs and ideas in the university and during the student period. The knowledge, attitude, and research performance of students in the field of health and treatment can play an effective role in the field of public health policies, providing health services, as well as the efficiency of the trained forces to fulfill their mission. This study was conducted to investigating the knowledge, attitude, and performance of students towards research in the Health Faculty of Hormozgan University of Medical Sciences in 2022.

Methodology
The present study was a descriptive-analytical study that was conducted cross-sectionally on all undergraduate students of Hormozgan University of Medical Sciences, Faculty of Health. The sample size (N) was equal to 200 people, and due to a series of restrictions and lack of necessary access to students, 164 of them were participated in this study. To conduct research, the code of ethics (IR.HUMS.REC.1401.133) obtained in the Faculty of Health of Hormozgan University of Medical Sciences. Then a standard questionnaire was applied to investigate students' knowledge, attitude, and performance towards research. The data collected via a questionnaire consisting of four sections of demographic characteristics, knowledge assessment, attitude, and research performance of students. Wrong answers were given a score of zero and correct answers were given a score of 1. The ranking of the students' knowledge based on the obtained score was as follows: 1. Poor level (0-7), 2. Average level (8-11), 3. Good level (12-15). In the attitude section, each question had a score between 1 and 5. In this study, scores of 15-34 were considered as poor attitude, scores of 35-59 as average attitude, and scores of 60-75 as good attitude. In the functional questions section, each question had a score between 0-3. Based on the results, scores of 0-10 were considered as poor performance, scores of 11-20 as average performance, scores of 21-30 as good performance, and scores greater than 30 as excellent performance. The obtained data were statistically analyzed using descriptive and analytical statistics (T-Test, ANOVA, etc.) at a significance level of p<0.05 in SPSS V25.0 software. In order to describe and analyze the data, frequency distribution tables, graphs, index of central tendency (mean, median and mode), and dispersion index (variance, standard deviation, coefficient of variation and their range) are used.

Results
Among 164 studied students, 29 (17.7%) were male, and 135 (82.3%) were female. The information of students participating in the study showed that 85.4% of students were single and the rest were married. The largest number of students participating in this study (36%) are related to the field of environmental health engineering, and other fields are 23.8%, 20.7%, and 19.5%, respectively, related to the fields of public health and occupational health engineering, and biology and vector control. About 72% students lived in dormitories. The relationship between each of the three parts of students' knowledge, attitude, and research performance using Pearson's correlation (at a significance level of 0.05) indicates a correlation of 0.325 between knowledge and attitude, a correlation of 0.334 between knowledge and performance, and the correlation was 0.285 between attitude and performance. The relationship between each part of students' knowledge, attitude, and research performance with their educational level (average) was also investigated. It was observed that there was a positive and significant correlation (0.193) between students' GPA and their research performance. The analysis of the relationship between the variables of gender, marital status, residence status, membership in the student research committee, and field of study using the T-Test showed that the knowledge of girls was significantly higher than that of boys (p<0.05) but in the field of attitude and No significant difference was observed between boys and girls. Regarding the marital status, no significant relationship was observed between the knowledge, attitude, and performance of single and married students. Statistical analysis and examination of the data obtained from the performance of the studied students according to their living conditions showed that the non-dormitory students had a higher average than the dormitory students (p<0.05), but there was a significant difference between their knowledge and attitude. There were no dormitory and non-dormitory people. Dormitory people had a weaker performance than non-dormitory people, which can be due to reasons such as the psychological effect caused by being away from the family environment, the lack of access to free time due to the creation of friendly meetings in the dormitory environment. It should have suitable facilities and space for studying and conducting research. In the study conducted by Izadi et al. at Isfahan University of Medical Sciences, there was a significant statistical relationship between the level of attitude and the place of residence of people; So that the students living in the dormitory had a better attitude about research, which is contrary to the results of the present study.
The knowledge, attitude, and research performance of students who were members of the student research committee were higher than other students. Regarding the field of study of the students, a significant difference (p<0.05) was observed in the average score of knowledge (0.032) and performance (0.014) of students studying in different fields of study at the undergraduate level. The results of the ANOVA statistical test on the relationship between students' knowledge, attitude, and performance with the students' academic year showed that, in general, the average scores related to knowledge, attitude, and research performance increased with the increase of the academic year, and therefore the difference There was a significance between students working and studying in different academic semesters (p<0.05). These results are consistent with the findings of Ghafornia et al.'s study (2004) in Isfahan. In a study related to chiropractic students in England, the attitude of 76% of these students towards research was investigated. In this study, the final year students' views on research were significantly different from the first year students and they had a more positive attitude, which is consistent with the results of the present study. In addition, in a study that was conducted in connection with the students of Shiraz University of Medical Sciences in order to investigate their knowledge and attitude about research, the attitude of students in lower educational levels towards research was positive compared to postgraduate students.

Conclusion
Based on the results, it is necessary to find ways to overcome the obstacles faced by students and motivate them to participate in research. Faculties of medical sciences can by updating their curricula and focusing on research-oriented activities, teaching research methods and research empowerment of students, allocating time, developing spaces, facilities, budgets, and research opportunities, forming and Expanding student research cores, assigning supervisors for student research, encouraging and persuading faculty members to participate in student research, provide research experience for all students in faculties of medical sciences. What is certain is that efforts to comprehensively evaluate this issue and to find ways to overcome the existing obstacles can lead to an increase in the participation of students in various fields of medicine in research.
