Physical activity (PA) promotes survival and mitigates symptoms in older breast cancer survivors (BCS), especially to reduce joint pain associated with adjuvant hormonal treatment. The purpose is to describe the adaptation process for an evidence-based exercise and education curriculum (i.e., Fit & Strong!) to support older BCS participating in the Using Exercise to Relieve Joint Pain and Improve Aromatase Inhibitor Adherence in Older Breast Cancer Survivors trial. We reviewed all educational materials with scientific/clinical experts to identify necessary content changes. Next, we conducted semistructured phone interviews with BCS to review all educational materials and conducted a real-time pretest for the trial. Overall, BCS found the adapted materials and experience acceptable (mean score of 9.2/10 for satisfaction). Content changes included simplifying exercise instructions, prioritizing content related to the trial goals, and updating photographs. Because of COVID, the pretest was conducted via Zoom. Our multistep adaptation process provided an acceptable intervention to meet the needs of older BCS. Lessons learned will be applied to the forthcoming pilot trial.

体力活动 (PA) 可促进老年乳腺癌幸存者 (BCS) 的生存并减轻症状，尤其是减轻与辅助激素治疗相关的关节疼痛。目的是描述基于证据的锻炼和教育课程的适应过程（即，  Fit & Strong！）支持老年 BCS 参与“利用运动缓解老年乳腺癌幸存者的关节疼痛并提高芳香酶抑制剂依从性”试验。我们与科学/临床专家审查了所有教育材料，以确定必要的内容更改。接下来，我们与 BCS 进行了半结构化电话采访，以审查所有教育材料，并对试验进行实时预测试。总体而言，BCS 认为改编的材料和体验是可以接受的（满意度平均分为 9.2/10）。内容更改包括简化练习说明、优先考虑与试验目标相关的内容以及更新照片。由于新冠疫情，预测试是通过 Zoom 进行的。我们的多步适应过程提供了可接受的干预措施，以满足老年 BCS 的需求。
