Reliability and validity of Chinese version of attitudes towards vital signs monitoring scale

Objective To translate the attitudes towards vital signs monitoring scale (V-scale) and to test the reliability and validity of it. Methods We carried out translation, back-translation and culture adaptation to confirm the Chinese version scale. From March to August 2018, we investigated 420 nurses of general wards from three Class Ⅲ Grade A general hospitals in Beijing with the Chinese version of V-scale. The reliability and validity of the scale was evaluated by exploratory factor analysis, confirmatory factor analysis and internal consistency test. Results The Chinese version of V-scale had 16 items with 0.93 for the content validity. A total of 5 common factors (workload, operation skill, communication, key indicators and knowledge) were extracted by exploratory factor analysis with 65.724% for the total variance contribution. Confirmatory factor analysis showed that the scale was with the good level of fit indices in each item, and adaptation test values all reached the standard level. The Cronbach's α coefficient of the total scale was 0.761 and Cronbach's α coefficients of all dimensions ranged from 0.579 to 0.809. The retest reliability of the scale was 0.778. Conclusions The Chinese version of V-scale has the good reliability and validity which could be used to assess ward nurses' attitudes towards vital signs monitoring to identify disease progression in China.
