这项观察性研究旨在将针对普通人群的计算机定制步骤建议转变为针对乳腺癌幸存者的可行建议，并测试其可用性。首先，对最初的设计进行了几次调整(增加了与癌症相关的体力活动(PA)障碍和信念，以及自我管理策略，以提高幸存者的个人控制力)。其次，调整后的建议被分两个阶段进行评估：(1)在健康女性(n=3)和幸存者(n=6)中进行可用性测试；(2)在乳腺癌幸存者(n=8)中进行为期3周的过程评估。初步的可用性测试显示，登录过程中没有出现问题；然而，三名幸存者误解了一些问题。在完善了问卷和建议后，幸存者评价这些建议有趣、易于阅读、易于理解和可信。不活跃的幸存者发现这个建议很新颖，但太长了。进程评价表明，大多数妇女(n=5/8)报告步骤增加。使用计步器监测步数被认为是更活跃的重要激励因素。总之，这项研究初步支持了为乳腺癌幸存者提供的基于计步器的计算机定制PA建议的可用性和可接受性。在测试了这种干预的有效性和有效性后，该工具可以扩大PA在乳腺癌幸存者中的推广范围。
This observational study aimed to adapt a computer-tailored step advice for the general population into a feasible advice for breast cancer survivors and to test its usability. First, several adaptations were made to the original design (adding cancer-related physical activity (PA) barriers and beliefs, and self-management strategies to improve survivors' personal control). Second, the adapted advice was evaluated in two phases: (1) a usability testing in healthy women (n = 3) and survivors (n = 6); and (2) a process evaluation during 3 weeks in breast cancer survivors (n = 8). Preliminary usability testing revealed no problems during logging-in; however, three survivors misinterpreted some questions. After refining the questionnaire and advice, survivors evaluated the advice as interesting, attractive to read, comprehensible and credible. Inactive survivors found the advice novel, but too long. The process evaluation indicated that the majority of the women (n = 5/8) reported increased steps. Monitoring step counts by using a pedometer was perceived as an important motivator to be more active. To conclude, this study provides initial support for the usability and acceptability of a computer-tailored pedometer-based PA advice for breast cancer survivors. After testing efficacy and effectiveness of this intervention, this tool can broaden the reach of PA promotion in breast cancer survivors.
