Abstract: Breast cancer patients consistently reported psychosocial adjustment difficulty in their sense of femininity after breast removal surgery. In view of this, the present study aimed to explore the effects of three femininity-related concepts on emotional reactions towards breast removal surgery - femininity schema, femininity loss appraisals, and femininity contingency of self-worth. 212 women without breast cancer history participated in this study. They completed a questionnaire which included a hypothetical scenario of breast removal. Results showed that women who considered the breast of a high relative importance in femininity schema, and depended their self-worth highly on sense of femininity, reported greater increase in negative emotions after hypothetical breast removal. This effect was mediated by femininity loss appraisals. Implications and future directions were discussed. DOI: 10.5353/th_b5070063 Subjects: Breast - Cancer - Patients - Psychology
