Translation, cultural adaptation, validation, and reliability study of the Quick-EBP-VIK instrument: Chinese version.

Abstract

Valid and reliable instruments for measuring are needed. To add knowledge to the subject of tools of evidence-based practice (EBP) evaluation in mainland China, the present study aims to translate the Quick-EBP-VIK into Chinese, which is an instrument for the assessment of nurses' value, knowledge, and implementation of EBP, and to evaluate the metric characteristics of the Chinese version. In this methodological study, a total sample of 402 nurses from mainland China was applied. Construct validity was evaluated by using factor analysis and further supported through known-group validity. A panel of experts examined the content validity. Internal consistency was determined using composite reliability and Cronbach alpha. The intraclass correlation coefficient (ICC) was calculated to assess test-retest reliability. The exploratory factor analysis revealed a three-factor structure model same to the original instrument. The confirmatory factor analysis showed a good fit model with a comparative fit index of 0.957 and a root mean square error of approximation of 0.065. Significant differences were found in the item means of the tool between nurses who received EBP training and those who had not, which supported the known-group validity. The Cronbach alpha and composite reliability for the three subscales were all higher than 0.70. The ICC ranged from 0.569 to 0.928 for the three subscales and from 0.494 to 0.903 for the items included in the instrument. The Chinese version of the Quick-EBP-VIK has evidence of acceptable reliability and validity and can be used to measure value, knowledge, and implementation of EBP for Chinese nurses.
