Translation and validation of the SABIS Scale for the Portuguese population

Background: The suffering caused by breast cancer treatments interferes with women’s self-image and the couple’s sexuality. Objective: To translate, adapt and validate SABIS Scale for women with breast cancer. Methodology: Psychometric study. Each scale was analyzed through face validity, content validity, internal consistency, exploratory factor analysis, confirmatory factor analysis, convergent validity, and discriminant validity. Results: The Body Image Scale obtained a two-factor structure and the Sexual Adjustment Scale a three-factor solution, with a variance of 80.02% and 83.5%, respectively. The confirmatory factor analysis confirmed the two-factor structure of the first scale and revealed a one-factor structure for the second scale. Both scales showed good fit indices. Conclusion: The psychometric properties of this version of the SABIS are similar to those of the original version. Therefore, it is a valid and reliable instrument for assessing the body image and sexual adjustment of Portuguese women with breast cancer.
