PURPOSE This study assessed the effectiveness of the Better Life After Cancer: Energy, Strength, and Support (BLESS) program, a 12-week social capital-based exercise adherence program for breast cancer survivors (BCS), regarding cancer-related fatigue (CRF), quality of life (QOL), physical activity, and psychosocial characteristics. METHODS Forty-eight BCS with moderate or high (≥ 4) CRF participated in this randomized control trial (intervention group n = 23, control group n = 25). The intervention group participated in small group sessions to activate social capital while targeting CRF in supervised physical exercises supplemented by home-based physical exercises. The control group was only given written information on exercise. A questionnaire was used to assess CRF, QOL, physical activity, depression, anxiety, sleep quality, and social capital. RESULTS The majority of participants had undergone surgery less than 2 years ago. After participating in BLESS, the CRF behavioral/severity domain significantly decreased (t = 2.642, p = 0.011) and physical activity significantly increased (t = - 2.049, p = 0.046) in the intervention group, in comparison with the control group; there were no significant post-intervention differences in the control group. Both groups showed improvements in sleep quality, depression, anxiety, and QOL. CONCLUSION The BLESS program decreased behavioral/severity in the CRF and increased physical activity after 12 weeks among BCS. Future research needs to evaluate whether the promising results on physical activity and behavioral fatigue observed in the short term will persist over time. Also, longer-term effects should be examined.

对患有中度疲劳的乳腺癌幸存者进行基于社会资本的运动坚持干预的事前分析：一项随机对照试验。


目的 本研究评估了癌症后的更好生活：能量、力量和支持 (BLESS) 计划的有效性，该计划是一项针对乳腺癌幸存者 (BCS) 的为期 12 周的基于社会资本的运动坚持计划，针对癌症相关疲劳 (CRF) ）、生活质量（QOL）、体力活动和社会心理特征。方法 48 名具有中度或高（≥ 4）CRF 的 BCS 参加了这项随机对照试验（干预组 n = 23，对照组 n = 25）。干预组参加小组会议以激活社会资本，同时以 CRF 为目标，在监督下进行体育锻炼，并辅以家庭体育锻炼。对照组仅获得有关运动的书面信息。使用问卷评估 CRF、QOL、体力活动、抑郁、焦虑、睡眠质量和社会资本。结果 大多数参与者在不到两年前接受过手术。参与 BLESS 后，与对照组相比，干预组的 CRF 行为/严重程度显着下降（t = 2.642，p = 0.011），体力活动显着增加（t = - 2.049，p = 0.046）；对照组在干预后没有显着差异。两组患者的睡眠质量、抑郁、焦虑和生活质量均有所改善。结论 BLESS 计划在 12 周后减少了 BCS 中 CRF 的行为/严重程度并增加了体力活动。未来的研究需要评估短期观察到的体力活动和行为疲劳的有希望的结果是否会随着时间的推移持续存在。此外，还应检查长期影响。
