Interventions promoting physical activity among cancer survivors improve their functioning, reduce fatigue and offer other benefits for cancer recovery and risk reduction for future cancer. There is a need for interventions that can be implemented on a wide scale. Our 12-week theory-based exercise intervention that was delivered by peer coaches by telephone was efficacious in significantly increasing moderate-to-vigorous physical activity (MVPA) among breast cancer survivors, in randomized controlled trial. The peer coaches from the American Cancer Society’s Reach to Recovery program were trained and supervised to deliver the intervention called Moving Forward Together (MFT) (Pinto, Stein & Dunsiger, 2015). Our goal is to prepare for wider implementation of MFT by adapting an existing web platform (Mentor1to1™) for the intervention and collect key indices to prepare for large scale implementation. The parent grant has two phases: in Phase 1 (completed), we worked with the InquistHealth team to modify Mentor1to1™for the MFT intervention creating webMFT, and in Phase 2, we will conduct a randomized controlled trial in which 10-12 peer coaches will deliver webMFT to 56 breast cancer survivors who will be randomized to receive either webMFT or MVPA Tracking. All study participants will receive a Fitbit activity tracker which they will be asked to wear each week for 12 weeks. webMFT participants, in addition, will receive weekly counseling calls delivered via the web platform. We will examine survivor outcomes (objectively measured MVPA and self-reported fatigue, quality of life, physical functioning and mood) at baseline and 12 weeks and compare groups at 12 weeks. In this supplement, we will: 1) code the webMFT intervention for Behavior Change Techniques (BCTs) that we intend to deliver from coach training materials, using a publicly available taxonomy (Michie et al., 2013). We will advance further and code BCTs that are implemented during intervention delivery by coding BCTs from audio-recordings of counseling calls. We will determine the ratio of implemented BCTs to intended BCTs to predict intervention adherence (number of counseling calls delivered) and survivors’ MVPA minutes/week for 12 weeks, as recorded by Fitbit activity trackers. 2) add measures to assess survivors’ intrapersonal (3 domains of self-efficacy, use of behavior self-regulation strategies, and affective response to physical activity) and intrapersonal variables (social support for exercise) at baseline, 4, 8 and 12 weeks. These theory-based variables, representing levels of the Social-Ecological Model, collected during the intervention phase will be used to predict intervention adherence and survivors’ MVPA minutes/week. Data on BCTs and changes in theoretical constructs at the intra-and interpersonal levels will be analyzed to elucidate the process of behavior change initiation (per NOT-OD-22-140). The results will advance knowledge of designing interventions with BCTs that are effective in motivating cancer survivors to become active and thereby improve their functioning and recovery.

促进癌症生存中体育活动的干预措施可以改善其功能，减少疲劳和 为癌症恢复和降低未来癌症的风险提供其他好处。需要干预 可以大规模实施。我们提供的为12周的基于理论的运动干预 通过电话的同伴教练在显着提高现代到凶猛的体育锻炼方面有效 （MVPA）在乳腺癌存活中，在随机对照试验中。美国人的同伴教练 癌症协会的到达恢复计划接受了培训和监督，以提供所谓的干预措施 一起前进（MFT）（Pinto，Stein＆Dunsiger，2015年）。我们的目标是为怀尔德做准备 通过调整现有的Web平台（Mentor1to1™）进行干预并收集MFT 为大规模实施做准备的关键指标。父母赠款有两个阶段：在第1阶段 （完成），我们与Incisthealth团队合作，修改MET1TO1™以创建MFT干预 WebMFT，在第2阶段，我们将进行一项随机对照试验 将Webmft提供至56种乳腺癌存活，他们将被随机分配以接收WebMFT或MVPA 追踪。所有研究参与者都会收到一个Fitbit活动跟踪器 12周。此外，WebMFT参与者将接收每周通过网络发送的咨询电话 平台。我们将检查生存结果（客观测量的MVPA和自我报告的疲劳，质量 生命，身体功能和情绪）在基线和12周时，并在12周时比较组。 在此补充中，我们将：1）编码行为变化技术（BCT）的WebMFT干预措施 我们打算使用公开分类法从教练培训材料中传递（Michie等，2013）。 我们将通过编码BCT来进一步进一步进一步发展，并在干预交付过程中实施的代码BCT 从咨询电话的音频录制中。我们将确定实施的BCT与预期的BCT的比率 预测干预依从性（已发送咨询电话的数量）和幸存者的MVPA分钟/周 如Fitbit活动跟踪器所记录的，持续12周。 2）添加措施评估生存的人际（3 自我效能的领域，使用行为自我调节策略以及对体育活动的情感反应） 以及基线4、8和12周的人际变量（对运动的社会支持）。这些基于理论的 代表在干预阶段收集的社会生态模型级别的变量将是 用于预测干预依从性和生存的MVPA分钟/周。有关BCT和更改的数据 将分析在人际关系层面的理论结构，以阐明行为的过程 更改计划（PER NOT-OD-22-140）。结果将提高有关设计干预措施的知识 有效激发癌症生存的BCT，从而改善其功能 和恢复。
