Attitudes toward mammography: questionnaire psychometric properties

Abstract

Purpose

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

Design/methodology/approach

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.

Findings

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.

Originality/value

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.
