Attitudes toward mammography: questionnaire psychometric properties

The purpose of this paper is to evaluate the Persian version of the Attitude toward Breast Cancer Screening Procedures Scale (ABCSPS) among Iranian women.

In this methodological study, 1,000 Iranian women completed a demographic questionnaire and the 14-item Persian ABCSPS. The scale’s construct validity was evaluated using exploratory and confirmatory factor analysis. Internal consistency and reliability were assessed using Cronbach’s α and McDonald’s coefficient ω.

The exploratory factor analysis revealed a two-factor solution accounting for 55.1 percent of the variance. The two-factor measurement model had a good fit with all factor loadings greater than 0.5, which were statistically significant. The results showed good reliability and internally consistency (α=0.767 and 0.872; ω =0.979 and 0.997). Moreover, model structure was invariant across different income groups.

The Persian ABCSPS translation demonstrated good validity and reliability among Iranian women. The results also showed that the scale had a multidimensional structure. Regarding proper psychometric properties, the validated scale can be used in future studies as a reliable and relevant breast cancer screening attitude measure.
