Abstract

Introduction: The Breast Cancer Screening Beliefs Questionnaire (BCSBQ) is a validated instrument designed to assess beliefs related to breast cancer screening. Although the BCSBQ has been validated in several populations, including Chinese, Arabic, and Korean women residing in Australia, its psychometric properties have not been assessed among Iranian women. Given the cultural differences and the scarcity of local data, this study aimed to translate, culturally adapt, and evaluate the validity and reliability of the Persian version of the BCSBQ among Iranian women. Materials and Methods: This methodological study involved a forward–backward translation process of the original questionnaire. Face, content, construct, convergent, and discriminant validity were assessed. Exploratory factor analysis (EFA) was conducted using the Principal Component Analysis (PCA) method with Varimax rotation, which was applied to identify underlying factors and ensure that items grouped coherently based on their correlations. Confirmatory factor analysis (CFA) was then used to assess the fit of the three-factor model. Internal consistency was evaluated using Cronbach's alpha coefficient. Data analysis was performed using SPSS (version 20) and Amos (version 24) software. Results: The Persian version of the questionnaire consisted of 13 items across three dimensions. The EFA confirmed the three-factor structure, which explained approximately 59.72% of the total variance. The CFA demonstrated an appropriate model fit (RMSEA = 0.05, CFI = 0.94, GFI = 0.95). Since CFA indices of CFI > 0.90 and RMSEA < 0.06 indicate acceptable model fit, the results confirmed the adequacy of the three-factor model. Cronbach's alpha values for the subscales ranged from 0.74 to 0.83. Convergent validity was supported by significant correlations between each item and its respective subscale, while low correlations between unrelated dimensions confirmed discriminant validity. Conclusion: The Persian version of the BCSBQ is a valid, reliable, and culturally appropriate tool for assessing Iranian women’s beliefs and attitudes toward breast cancer screening. This culturally adapted instrument can support targeted educational programs and inform public health strategies to improve breast cancer screening uptake among Iranian women.
