Psychometric validation of the Chinese version of the empowerment scale for pregnant women

Empowering pregnant women is a crucial process that healthcare providers should evaluate, as empowerment is a meaningful indicator that can reflect the impact of health promotion and education in antenatal care. The Empowerment Scale for Pregnant Women (ESPW) is a reliable and valid instrument for measuring empowerment. The cross-sectional study was conducted to translate and validate the psychometric properties of the ESPW among 526 pregnant women in China. The forward-backward method was used to translate the English version of the ESPW into the Chinese version. Reliability was examined with the internal consistency and test-retest coefficients. Validity was analyzed with structural, dimensionality, convergent, discriminant, and concurrent validity. The Cronbach's α value of 0.97 and the intraclass correlation coefficient of 0.98 (95% confidence interval [CI], [0.96, 0.99]) demonstrated excellent internal consistency and test-retest reliability. Exploratory factor analysis revealed that five factors with eigenvalues > 1 explained 68.41% of the total variance. Confirmatory factor analysis verified an acceptable model that fit the data exceptionally. The Chinese-translated version of the ESPW (CV-ESPW) had acceptable convergent and discriminant validity. Concurrent validity was supported by the correlation between the total scores of the CV-ESPW and the Chinese version of the Patient Perceptions of the Empowerment Scale (r = 0.64, p < 0.001). The CV-ESPW is a valid and reliable assessment tool for measuring pregnant women's empowerment in China and can potentially contribute to evaluating the effectiveness of programs that empower pregnant women.
