To adapt and partly validate a Danish online version of the patient-reported outcome measure (PROM) Oxford Physical Activity Questionnaire ("OPAQ") and evaluate mobile phones and tablets as data capturing tool to identify potential problems and deficiencies in the PROM prior to implementation in the full study.
The OPAQ was translated into Danish by a formalised forward-backward translation procedure. Face validity was examined by interviewing 12 school students aged 10-15, recruited from two Danish public schools. After modifications, the online version of the Danish OPAQ was pilot tested in a convenience sample of seven school students for 1 week. Simultaneous objective accelerometer data were captured during the registration period.
No major challenges were identified when translating OPAQ. Based on the interviews, the Danish version of OPAQ was perceived to be easy to understand in general, and the questions were relevant for tracking activities during the week. Five of the 12 participants had difficulties with understanding the introductory question: "what is your cultural background" in the original OPAQ. The interviews revealed that the participants recalling 7 days forgot to record some of the physical activity they had done during the week, indicating issues with the weekly recall method. After transforming to the online version, this was reported to be easy and quick to fill in (taking 1-3 min per day), and participants reported the daily design was helpful to remember activities. There was good correspondence between the online version and objective actigraphs with a tendency to underreport. Six participants reported 10-60 min less moderate to vigorous physical activity compared to the actigraphs, while one participant reported 3 min more.
Participants found the online OPAQ quick and easy to complete during a 1-week period. Completing daily rather than weekly may help limit issues with recall. Overall, there was good agreement between the objective actigraphs and the OPAQ, though the OPAQ tended to slightly underreport moderate to vigorous physical activity. The Danish online version of OPAQ may be useful for capturing school students' physical activity when objective measures are not feasible.
改编并部分验证丹麦语在线版患者报告结局测量工具（PROM）牛津体力活动问卷（“OPAQ”），并评估手机和平板电脑作为数据采集工具，以便在全面研究实施之前识别该PROM中潜在的问题和缺陷。
通过正式的前后翻译程序将OPAQ翻译成丹麦语。通过采访从两所丹麦公立学校招募的12名10 - 15岁的在校学生来检验表面效度。修改后，丹麦语OPAQ在线版在7名在校学生的便利样本中进行了为期1周的预测试。在记录期间同时采集客观的加速度计数据。
翻译OPAQ时未发现重大挑战。根据访谈，丹麦语版OPAQ总体上被认为易于理解，问题与追踪一周内的活动相关。12名参与者中有5人难以理解原始OPAQ中的介绍性问题：“你的文化背景是什么”。访谈显示，回忆7天情况的参与者忘记记录他们在一周内进行的一些体育活动，这表明每周回忆法存在问题。转换为在线版后，据报告填写起来轻松快捷（每天需要1 - 3分钟），参与者表示每日设计有助于记忆活动。在线版与客观活动记录仪之间存在良好的对应关系，但有少报的倾向。与活动记录仪相比，6名参与者报告的中度至剧烈体力活动少了10 - 60分钟，而1名参与者报告多了3分钟。
参与者发现在为期1周的时间里在线OPAQ快速且易于完成。每日而非每周完成可能有助于减少回忆问题。总体而言，客观活动记录仪与OPAQ之间存在良好的一致性，尽管OPAQ往往会略微少报中度至剧烈体力活动。当客观测量不可行时，丹麦语在线版OPAQ可能有助于获取在校学生的体力活动情况。
