Abstract

Background: Breast cancer is the most prevalent cancer among women in Greece. It is crucial to have a simple, trustworthy and effective instrument for assessing the factors that impact cancer screening behaviors. Objective: This study aimed to translate and validate the Greek version of the Breast Cancer Screening Beliefs Questionnaire (BCSBQ). Methods: In this cross-sectional methodological study conducted from April to June 2024, 202 Greek women aged 21 to 69 years participated using a snowball sampling method. A backward-forward translation process was performed on the BCSBQ. The study evaluated the face, content, and constructs validity of the questionnaire. A confirmatory factor analysis was carried out to determine whether the data supported the 3-factor structure of the instrument. Additionally, the reliability of the BCSBQ was measured using Cronbach’s alpha and intra-class correlation coefficients. Result: The results of the confirmatory factor analysis demonstrated the presence of three distinct factors: attitude, knowledge, and barriers to screening. The three-factor model was supported by standard indices, with the following values: chi-square = 112.5, RMSEA = 0.079, SRMR = 0.057, CFI = 0.94, and NNFI = 0.942. The instrument also showed a satisfactory Cronbach’s alpha of 0.814, while the Cronbach’s alpha values for the three subscales ranged from 0.72 to 0.84. The mean scores observed on the three subscales in this study were remarkably high (Attitudes=76.7±23.9, Knowledge=80.9±20.1, Barriers=89.9±12.7). Conclusion: The three-factor structure of the BCSBQ-12 demonstrated valid and reliable results among Greek women. Given its strong psychometric properties, this tool can be utilized in future studies to assess women’s beliefs regarding breast cancer screening in Greece.
