乳腺癌及其治疗导致严重的身体变化，可能对女性的形象产生负面影响。乳腺癌女性的身体接纳对于提高她们的形象和整体生活质量至关重要。尽管具有重要意义，目前尚无专门用于评估癌症患者身体接纳的工具。本研究旨在开发一种适用于乳腺癌女性的身体接纳量表（BAS-BC）。根据身体接纳的概念框架，初步项目由三名临床专家和五名经验专家审查。通过六名临床专家的内容效度评估和20名乳腺癌女性的试验，编制了初步问卷。通过对411名乳腺癌手术患者的在线调查，评估了量表的效度和信度。该量表由六个因素（面临困境、理解、适应、恢复日常生活、成功过渡和展望未来）共17个项目组成。量表的效度，包括结构效度、交叉效度、已知群体效度和准则效度，均令人满意，其克伦巴赫α系数为0.91。BAS-BC展现出良好的效度和信度。BAS-BC将通过为未来研究提供基础信息，从而有助于提高女性乳腺癌幸存者的生活质量。BAS-BC可能使护士能够提供量身定制的干预措施，以促进身体接纳。版权所有 © 2023 Elsevier Inc.。保留所有权利。

Breast cancer and its treatment result in drastic physical changes that can negatively affect a woman's body image. Body acceptance in women with breast cancer is crucial in enhancing their body image and overall quality of life. Despite its significance, there are currently no specific tools to measure body acceptance among cancer patients. This study aimed to develop a Body Acceptance Scale for Women with Breast Cancer (BAS-BC).The scale's initial items were generated based on a conceptual framework of body acceptance and were reviewed by three clinical and five experiential experts. A preliminary instrument was developed through a content validity assessment by six clinical experts and a pilot test with 20 women with breast cancer. Validity and reliability were evaluated via an online survey of 411 women who had undergone breast cancer surgery.The scale consists of 17 items across six factors (encountering, understanding, adaptation, return to daily life, successful transition, and leap into the future). The scale's validity-including construct validity, cross-validity, known-groups validity, and criterion validity-was satisfactory, exhibiting a Cronbach α of .91. The BAS-BC demonstrated good validity and reliability.The BAS-BC will contribute to improving the quality of life of female breast cancer survivors by providing fundamental information for future research. The BAS-BC may enable nurses to provide tailored interventions to promote body acceptance.Copyright © 2023 Elsevier Inc. All rights reserved.
