Cultural adaptation and validation of the Cardiff fertility knowledge scale among Chinese childbearing age population

Objective To assess translate the Chinese version of Cardiff fertility knowledge scale (CFKS) reliability and validity among Chinese childbearing age population. Methods The Chinese version of CFKS was developed through Brislin’s translation/back-translation method and modified through cultural adaptation and semantic analysis. The reliability and validity of the Chinese version of CFKS was tested based on an investigation containing 800 students from 3 universities and 1115 childbearing age people from 6 communities in Hunan Province. Results The Cronbach’s α coefficient for the overall Chinese CFKS was 0.811, and the test-retest reliability was 0.816. The Scale-Content Validity Index (S-CVI) was 0.950 with the Item-Content Validity Index (I-CVI) ranging from 0.875 to 1.000. Three common factors were extracted and the accumulated variance contribution rate was 51.149%. In addition, the load value of 13 items on the corresponding common factor was greater than 0.4. Conclusion The Chinese version of CFKS could be valuable to evaluate fertility knowledge among the childbearing age population.
