Physical inactivity has been a great public health concern among breast cancer survivors (BCS), especially during the COVID-19 pandemic, as it is closely related to a higher risk of cancer recurrence and mortality. The positive impacts of psychosocial beliefs in promoting physical activity (PA) have been well acknowledged. Therefore, this study aimed to explore the effects of psychosocial beliefs on PA in BCS to prevent physical inactivity. Furthermore, we examined the relationships between daily activities, trip behaviors, and associated subjective well-being.
This study used a cross-sectional, descriptive study design. Female BCS who were able to exercise regularly completed the battery of assessments in March 2021. Specifically, the international PA questionnaires and the adapted PA-related psychosocial beliefs questionnaires were used to assess BCS's PA and psychosocial beliefs, respectively. In addition, the smartphone-based Day Reconstruction Method was utilized to measure subjective well-being. Data were analyzed using descriptive statistics, Chi-squared test, analyses of variance, and correlation analysis.
In the context of investigations during the COVID-19 pandemic, our study showed that 77.8% of BCS reported meeting PA guidelines. As the components of psychosocial beliefs, the change strategies, social support, and confidence were significantly associated with higher PA levels. Additionally, the protective effect of leisure/recreation activities among BCS on their emotional well-being was observed.
Overall, this study demonstrated the importance of understanding the relationship between BCS's psychosocial beliefs and PA during the pandemic. Notably, this study is unique because it used an application-based method to assess BCS' subjective well-being objectively.
身体活动不足是乳腺癌幸存者（BCS）的一个重大公共卫生问题，尤其是在 COVID-19 大流行期间，因为它与癌症复发和死亡风险增加密切相关。社会心理信念对促进身体活动（PA）的积极影响已得到充分认可。因此，本研究旨在探讨社会心理信念对 BCS 身体活动的影响，以预防身体活动不足。此外，我们还研究了日常活动、出行行为与相关主观幸福感之间的关系。
本研究采用横断面、描述性研究设计。能够定期锻炼的女性 BCS 在 2021 年 3 月完成了一整套评估。具体而言，使用国际 PA 问卷和改编的与 PA 相关的社会心理信念问卷分别评估 BCS 的 PA 和社会心理信念。此外，还使用基于智能手机的日常生活重建法来衡量主观幸福感。使用描述性统计、卡方检验、方差分析和相关分析来分析数据。
在 COVID-19 大流行期间的调查背景下，我们的研究表明，77.8%的 BCS 报告符合 PA 指南。作为社会心理信念的组成部分，改变策略、社会支持和信心与较高的 PA 水平显著相关。此外，还观察到 BCS 休闲/娱乐活动对其情绪健康的保护作用。
总的来说，本研究表明在大流行期间了解 BCS 社会心理信念与 PA 之间关系的重要性。值得注意的是，本研究是独特的，因为它使用基于应用的方法客观地评估了 BCS 的主观幸福感。
