Development and Psychometric Validation of the Breast Cancer Stigma Assessment Scale for Women with Breast Cancer and Its Survivors

Background: The increase in breast cancer cases and breast cancer survival makes it advisable to quantify the impact of the health-related stigma of this disease. Purpose/Objectives: To develop and validate a breast cancer stigma scale in Spanish. Methods: Women diagnosed with, or survivors of, breast cancer were included. The development of the Breast Cancer Stigma Assessment Scale (BCSAS) involved both a literature review and personal interviews. Content validity was assessed using a Delphi study and a pilot test; construct validity was evaluated using an exploratory factor analysis; and convergent validity was assessed using six scales. Cronbach's alpha internal consistency and test-retest reliability were used to determine the reliability of the scales. Results: 231 women responded to the 28-item scale. The BCSAS showed good reliability, with alpha = 0.897. Seven factors emerged: concealment (alpha = 0.765), disturbance (alpha = 0.772), internalized stigma (alpha = 0.750), aesthetics (alpha = 0.779), course (alpha = 0.599), danger (alpha = 0.502), and origin (alpha = 0.350). The test-retest reliability was 0.830 (p < 0.001). Significant correlation was observed with event centrality (r = 0.701), anxiety-depression (r = 0.668), shame (r = 0.645), guilt (r = 0.524), and quality of life (r = -0.545). Conclusions: The BCSAS is a reliable and valid measure of stigma in women with breast cancer and its survivors. It could be useful for detecting stigma risk and establishing psychotherapeutic and care priorities.
