BACKGROUND: Due to the rapid advancement of medical knowledge, promotion in research 
is necessary to have the best clinical practice. Research Self‑efficacy (RSE) is the researcher’s 
confidence in their ability to conduct a specific study. The Evidence‑Based Practice (EBP) represents 
how to improve the quality of care and treatment of patients. RSE and EBP are the cornerstones 
of successful research and then efficacious medical practice.This study aims to evaluate RSE and 
acceptance of EBP and their correlation among medical students.
MATERIALS AND MEHODS: This is a cross‑sectional study designed on 600 clinical students at 
the medical school of Shiraz, using a census method in 2020. Students were invited to fill out the 
standardized Phillips and Russell’s questionnaires about RSE (4 domains, 33 questions) and Rubin 
and Parrish’s questionnaire of EBP (10 questions). The gathered data were analyzed through the 
SPSS at α = 0.05 using descriptive statistics, t‑test, Chi‑square, and multiple linear regressions.
RESULTS: There was a positive correlation between EBP and RSE score (P < 0.05). The results of 
linear regression test showed that all variables had a significant effect on our response variables and 
their effect were significant (P < 0.05). The highest mean score in RSE was shown in the subscale 
of writing skills (52.54). The lowest score was observed in the subscale of quantitative (student’s 
subjective assessment of their ability to work with statistically related data and formulas) as well as 
computer skills (35.61).
CONCLUSIONS: Students who participated in a research project, workshop, or Master of Public 
Health program got a higher RSE and EBP. Due to the positive correlation between RSE and EBP, 
we conclude that trained physicians who can research independently and use research evidence 
can find the best treatment approach for patients. These finding support the importance of integrating 
research education in medical curriculum to increase RSE and finally improvement of EBP among 
medical students.
