- Abstract
Objective: To develop a Chinese version of the Newest Vital Sign (NVS-CHN) instrument and evaluate its psychometric properties. Methods: To deal with cross-cultural adaptation problems, after translation of the NVS into Chinese, the Delphi method was used for experts and cognitive testing was used for participants. A cross-sectional study including 351 participants was conducted to assess the validity of the NVS-CHN. Internal reliability, criterion validity, and known-groups validity were investigated. The NVS-CHN was further validated against a suitable standard, the Chinese Citizen Health Literacy Questionnaire (CCHLQ). Results: The validity of the NVS-CHN was established by conducting a Delphi survey (three rounds) and cognitive testing (three rounds). Cronbach’s alpha was 0.71, indicating that internal consistency was acceptable. A Spearman’s correlation coefficient of 0.68 between the NVS-CHN and CCHLQ revealed excellent criterion validity. Differences in NVS-CHN scores by education level confirmed known-groups validity. A receiver operating characteristics analysis showed that the area under the curve was 0.81, indicating that the NVS-CHN was an accurate health literacy assessment tool. A score ≥ 4 out of 6 best identified participants with adequate health literacy. Conclusions: The NVS-CHN has excellent psychometrical reliability and validity, which make it a suitable tool to evaluate health literacy in China.
