Objective: This study aimed (1) to evaluate the internal consistency and test-retest reliability of the Vietnamese version of the Knowledge and Attitudes Survey Regarding Pain –revised questionnaire; and (2) to assess the relationship between the knowledge, attitudes and demographic factors in nurses.
 Materials and methods: A cross-sectional survey and a correlation research design was used to evaluate test-retest reliability. 154 participants were tested twice with a 2-week interval. Multivariate analysis was performed by using multiple linear regressions to test the relationship between demographic data with nurse’ knowledge and attitude of pain management.
 Results and Discussion: Reliability was confirmed by internal consistency (Cronbach α = 0.88) and test-retest reliability (intraclass correlation coefficient, 0.88). The results of multiple regression indicated that age, nurses had level 5, and nurses from internal medicine, ICU, emergency, obstetric, oncology department, those with previous education in pain management, and routinely assess pain for patients were predicted to KASRP score, accounting for 11.6%.
 Conclusion: The Vietnamese Knowledge and Attitudes Survey Regarding Pain- Revised questionnaire had satisfactory content validity and reliability for assessing pain management in nurses in Vietnam. Some demographic factors were predicted 11.6% of KASRP in Nurses. Further research need focus on those factors independently significant predicted to KASRP to improve nurse’s knowledge and attitude.
