基于移动的生态瞬时评估（EMA）是一种现场测量方法，其中电子设备提示一个人回答研究兴趣的问题。EMA有一个关键限制：中断负担。微交互-EMA（muEMA）可以在不牺牲测量的高时间密度的情况下减轻负担。在muEMA中，所有EMA提示都可以通过“一目了然”的微交互来回答。在之前的一项为期4周的试点研究中，比较了通过手机（phone-EMA）提供的标准EMA与通过智能手表（watch-muEMA）提供的muEMA，watch-muEMA显示出比phone-EMA更高的响应率和更低的感知负担，即使watch-muEMA中断率是phone-EMA的8倍。在基于智能手表的EMA上收集了一个新的4周数据集（即，watch-EMA，手表上有6个背靠背的多项选择题），以比较之前观察到的watch-muEMA的高响应率是使用微交互的结果，还是由于智能手表的新奇和可访问性。在依从性、完成率和第一次即时响应率方面，电话EMA和手表EMA之间没有统计学显著差异。然而，watch-muEMA应答率显著高于watch-EMA。该试点表明，（1）先前在watch-muEMA中观察到的高依从性和低负担可能是由于微交互问题技术，而不仅仅是使用手表与手机，（2）传统EMA（长时间调查）的依从性可能不会仅仅通过将调查交付从手机转移到智能手表来改善。
Mobile-based ecological-momentary-assessment (EMA) is an in-situ measurement methodology where an electronic device prompts a person to answer questions of research interest. EMA has a key limitation: interruption burden. Microinteraction-EMA(muEMA) may reduce burden without sacrificing high temporal density of measurement. In muEMA, all EMA prompts can be answered with 'at a glance' microinteractions. In a prior 4-week pilot study comparing standard EMA delivered on a phone (phone-EMA) vs. muEMA delivered on a smartwatch (watch-muEMA), watch-muEMA demonstrated higher response rates and lower perceived burden than phone-EMA, even when the watch-muEMA interruption rate was 8 times more than phone-EMA. A new 4-week dataset was gathered on smartwatch-based EMA (i.e., watch-EMA with 6 back-to-back, multiple-choice questions on a watch) to compare whether the high response rates of watch-muEMA previously observed were a result of using microinteractions, or due to the novelty and accessibility of the smartwatch. No statistically significant differences in compliance, completion, and first-prompt response rates were observed between phone-EMA and watch-EMA. However, watch-muEMA response rates were significantly higher than watch-EMA. This pilot suggests that (1) the high compliance and low burden previously observed in watch-muEMA is likely due to the microinteraction question technique, not simply the use of the watch versus the phone, and that (2) compliance with traditional EMA (with long surveys) may not improve simply by moving survey delivery from the phone to a smartwatch.
