Cross-Cultural Adaptation, Validity and Reliability of The Chinese Version of Miller Behavioral Style Scale

Abstract

Background: Health education basing on patients’ information-seeking style can improve the effect of health education and patients’ health outcomes. The Miller Behavioral Style Scale(C-MBSS) is widely used, but the Chinese version is lacking. The study aim was to test the reliability and validity of C-MBSS.Methods: The forward-back-translation procedure was adopted in the translation of the MBSS. Content validity was assessed in a panel of experts. In a sample of 1343 individuals including patients, patients’ caregivers, university students, and medical staff, reliability and construct validity were assessed using Cronbach’s alpha coefficient and factor analysis.Results: The C-MBSS achieved conceptual and semantic equivalence with the original scale. The item-level content validity index (I-CVI) of each item ranged from 0.78 to 1, and the averaging scale-level content validity index (S-CVI/ Ave) was 0.95. Thecronbach`s alpha coefficient for the scale and sub-scales were over 0.6. The exploratory factor analysis resulted in 2-factor assumption for each hypothetical threat-evoking scenario. Confirmatory factor analysis demonstrated a good fit between theoretical model and data, which provided confirmatory evidence for the second-order factor structure of 2-factor solution (Monitoring and Blunting).Conclusions: This study verified the reliability and validity of the C-MBSS and indicated that the C-MBSS can be used to identify individual`s information-seeking style in Chinese population.
