Translation, cross-cultural adaptation, validation, and reliability study of the Breast Cancer Fear Scale: Chinese version

Abstract Background Cancer-related fear has been identified as an important component of health-related behaviors. However, there is a lack of tools for measuring breast cancer fear in the Chinese healthcare context, which might hinder related studies in the Chinese population. The Breast Cancer Fear Scale developed by Champion was introduced, and its psychometric characteristics and factor structure were evaluated to provide a suitable and reliable measurement tool in China to assess the fear of breast cancer in Chinese women. Methods According to the Brislin back translation model, the Breast Cancer Fear Scale was translated into Chinese, 33 subjects were selected for the cognitive survey, 8 experts were invited for the content validity test, 245 subjects were surveyed via the convenience sampling method, and the reliability and validity of the scale were tested. Results The Chinese version of the Breast Cancer Fear Scale has 8 items in total. The content validity of the scale is 0.99, and the content validity of the item is 0.88 ~ 1.0. The expert's judgment basis (Ca) is 0.91, the expert's familiarity level (Cs) is 0.80, and the expert's authority coefficient (Cr) is 0.86. The Cronbach's α of the scale is 0.97. The retest reliability was 0.95. The project analysis shows that there are differences between groups, indicating that the discrimination of each item is good. Conclusions The Chinese version of the Breast Cancer Fear Scale has good reliability and validity and can be used to assess the fear of breast cancer in Chinese adult women.
