Abstract:Objective To translate the High-Risk Pregnancy Well-Being Index (HRPWBI) into Chinese and to test the reliability and validity of the Chinese version of the HRPWBI Scale. Methods The English version of the HRPWBI Scale was translated, back-translated, and culturally adapted using the Brislin translation model to develop the Chinese version of the HRPWBI Scale. A convenience sampling method was employed to select 482 high-risk pregnant women between April and July 2024 for a questionnaire survey to evaluate the reliability and validity of the Chinese version of the HRPWBI Scale. Results The Chinese version of the HRPWBI Scale consisted of five dimensions:physical and mental well-being, self-efficacy and independence, marital well-being, social well-being, and healthcare service well-being, comprising a total of 30 items. The cumulative variance contribution rate was 61.393%. Confirmatory factor analysis indicated good model fit indices (χ2/df=1.498,RMSEA=0.048,CFI=0.978,GFI=0.954,TLI=0.971,IFI=0.979). The scale-level content validity index(S-CVI) was 0.933, the overall Cronbach′s α coefficient was 0.908, and the test-retest reliability after a two-week interval was 0.866. The scores on the Chinese version of the HRPWBI Scale were positively correlated with the World Health Organization-Five Well-Being Index scores (r=0.448, P<0.05). Conclusion The Chinese version of HRPWBI Scare has good reliability and validity, which is suitable for evaluating the well-being of pregnant women with high-risk pregnancy under the Chinese cultural background.
