Background: Evidence-based practice (EBP) is used worldwide to improve the quality of patient care to provide cost-effective care. EBP is a mandate for nursing practice combining individual clinical judgment with available expertise to generate a positive outcome for the patient. Objective: The study aimed to describe the self- assessment of undergraduate nursing students about Knowledge, behavior, and attitude in relation to Evidence Based Practice. A Cross- sectional study design. Convenience sampling technique was used to include all consenting nursing students from fifth level to eighth level (3rd and 4th year) (n=255) student. The research was carried out at the Faculty of Nursing, Princess Nourah Bint Abdulrahman University. A self- administered questionnaire. The EBP was done by adopting EBP questionnaire that has been created by Upton et.al (2006) & Ruzafa-Martinez et.al (2017): The results indicated that our respondents generally viewed EBP positively and their attitudes towards EBP tended to be more positive than their knowledge and behaviors about EBP. Exactly 76.6% of respondents in our study had a positive attitude toward EBP. Finally, our study showed statistically significant correlations between practice, knowledge and attitudes related to evidence-based practice. Many studies have established that the three segments of knowledge, attitude, and behavior are inseparably interlinked and strength each other in EBP. Conclusion of our research showed that factor of training in EBP has an effect on nursing students' knowledge, attitudes and behaviors about EBP. To the possible extent, training will help to increase positive beliefs and attitudes regarding EBP. Further investigation regarding the effect of gender difference in EBP is needed.
