Assessment of the validity and reliability of the Vietnamese version of the Breast Cancer Screening Beliefs Questionnaire

Abstract

ObjectiveThe aim of this study was to evaluate the cultural adaptability and psychometric properties of the Vietnamese version of the Breast Cancer Screening Beliefs Questionnaire (BCSBQ). MethodsA total of 253 women aged 18 years and older with no history of breast cancer was included in the analysis. ResultsConfirmatory factor analysis showed an adequate fit for the hypothesized three-factor structure of the original version of the BCSBQ. The results indicated that the frequency of women’s breast cancer screening practices and their educational levels were significantly associated with “Attitudes towards general check-ups”. Demonstrating the Cronbach’s α of the three subscales ranged between 0.79 and 0.85 while the corrected item-total correlations for the hypothesized subscales ranged from 0.38 to 0.74, constituted a result which indicated that the Vietnamese version of the BCSBQ had satisfactory validity and internal consistency. ConclusionsThe Vietnamese version of the BCSBQ is a culturally appropriate, valid, and reliable instrument for examining the beliefs, knowledge, and attitudes about breast cancer and breast cancer screening practices among Vietnamese women living in Australia.
