Validity and Reliability Measurement of the Knowledge and Attitude Survey Regarding Pain Tool Vietnamese Version

Introduction: Knowledge and attitude regarding pain management is one of the factors with the highest predictive value and it can explain 69% of nurses' s pain management practice[2]. Therefore, a standard tool to measure the pain management knowledge and attitude of nurses in Vietnam is needed. Objective: Testing the validity and reliability of the Knowledge and attitudes survey regarding pain tool Vietnamese version (KASRP -V), so as to measure the nurse's pain management knowledge level in Vietnam Method: The psychometric properties testing of KASRP tool Vietnamese version has undergone a strict standardization process including testing for content validity, discriminant validity, test-retest reliability, internal consistency reliability. 6 experts assessed the content validity. 50 nurses and 73 nursing students were selected to collect data for the discriminant validity testing. Thirty nurses out of 50 nurses were selected to collect data for the internal consistency reliability and test-retest reliability testing. Results:The KASRP tool Vietnamese version includes 41 items, the CVI index for each item ranged from 0.83-1, S-CVI=0.996. The discriminant validity was verified because there was a difference in knowledge scores between the group of nurses with experience in patient care and the group of 4th years nursing students (Z=-2.256,p=0.01).. Internal consistency reliability was measured by Cronbach alpha score. The Cronbach alpha value of each item ranged from 0.885 - 0.887 and the total score was 0.888. The correlation coefficient between each item with the total ranged from 0.300 - 0.446. The ICC score = 0.977 (with 95% CI=0.631-0.994,p= .000) was measured to assess test-retest reliability Conclusion: This evaluation of the KASRP -V demonstrated acceptable validity and reliability
