Physical inactivity and sedentary behaviour are common amongst breast cancer survivors. These behaviours are associated with an increased risk of comorbidities such as heart disease, diabetes and other cancers. Commercially available, wearable activity trackers (WATs) have potential utility as behavioural interventions to increase physical activity and reduce sedentary behaviour within this population.
The purpose of the study is to explore the acceptability and usability of consumer WAT amongst postmenopausal breast cancer survivors.
Fourteen participants tested two to three randomly assigned trackers from six available models (Fitbit One, Jawbone Up 24, Garmin Vivofit 2, Garmin Vivosmart, Garmin Vivoactive and Polar A300). Participants wore each device for 2 weeks, followed by a 1-week washout period before wearing the next device. Four focus groups employing a semi-structured interview guide explored user perceptions and experiences. We used a thematic analysis approach to analyse focus group transcripts.
Five themes emerged from our data: (1) trackers' increased self-awareness and motivation, (2) breast cancer survivors' confidence and comfort with wearable technology, (3) preferred and disliked features of WAT, (4) concerns related to the disease and (5) peer support and doctor monitoring were possible strategies for WAT application.
WATs are perceived as useful and acceptable interventions by postmenopausal breast cancer survivors. Effective WAT interventions may benefit from taking advantage of the simple features of the trackers paired with other behavioural change techniques, such as specialist counselling, doctor monitoring and peer support, along with simple manual instructions.
身体活动不足和久坐行为在乳腺癌幸存者中很常见。这些行为与心脏病、糖尿病和其他癌症等合并症风险增加有关。市售的可穿戴活动追踪器（WAT）作为行为干预手段，在增加该人群身体活动和减少久坐行为方面具有潜在效用。
本研究旨在探讨绝经后乳腺癌幸存者对消费型WAT的可接受性和可用性。
14名参与者对从6种可用型号（Fitbit One、Jawbone Up 24、Garmin Vivofit 2、Garmin Vivosmart、Garmin Vivoactive和Polar A300）中随机分配的两到三个追踪器进行测试。参与者佩戴每个设备2周，然后在佩戴下一个设备之前有1周的洗脱期。四个焦点小组采用半结构化访谈指南，探讨用户的看法和体验。我们使用主题分析方法来分析焦点小组的文字记录。
我们的数据中出现了五个主题：（1）追踪器提高了自我意识和动力；（2）乳腺癌幸存者对可穿戴技术的信心和舒适度；（3）WAT的喜欢和不喜欢的功能；（4）与疾病相关的担忧；（5）同伴支持和医生监测是WAT应用的可能策略。
绝经后乳腺癌幸存者认为WAT是有用且可接受的干预措施。有效的WAT干预可能受益于利用追踪器的简单功能，结合其他行为改变技术，如专家咨询、医生监测和同伴支持，以及简单的手动说明。
