Abstract:

Objective To translate the Birth Beliefs Scale（BBS） into Chinese,and to assess the reliability and validity of Birth Beliefs Scale-Chinese（BBS-C）. Methods The Principle of Good Practice for Translation and Cultural Adaptation Process was followed to translate and back-translate the BBS. The cross-cultural revision of the translated BBS was carried out through expert consulting and pilot survey. An expert panel（n=7） was invited to conduct 3 rounds evaluation of BBS-C. A total of 593 pregnant women in late pregnancy were surveyed to evaluate the reliability and validity of the BBS-C. Results The item-level CVI of BBS-C was 0.86~1 and the scale-level CVI was 0.91. The Cronbach's α coefficient for the total scale was 0.76. The test-retest reliability coefficient of the subscales were 0.83 and 0.84. Confirmatory factor analysis showed that χ²/df=4.871,RMSEA=0.081,GFI=0.955,AGFI =0.909,IFI=0.914,TLI=0.855. Conclusion BBS-C has been proved to be valid and reliable,which can be used to evaluate the birth beliefs of Chinese pregnant women in late pregnancy.
