对研究参与者进行调查存在许多挑战，包括成本、时间以及获得高质量和可重复工作的能力。云外包（一种向云提供商付费以执行可在内部提供的服务的安排）有可能提供更大、更便宜且更通用的调查池。本研究的目的是使用亚马逊的 Mechanical Turk (MTurk) 来评估基于云的劳动力，以评估患者对医疗保健的看法。亚马逊 MTurk 上发布的一项全国在线调查包含 33 个多项选择题和开放式问题。使用 t 检验比较连续属性。我们在不到 3 天的时间里获得了 1084 份回复，总成本为 298.10 美元，在 6 小时内收到了 300 份回复。其中，44.74% (485/1084) 为男性，54.80% (594/1084) 为女性，代表 50 个州中的 49 个州，年龄在 18 至 69 岁之间。亚马逊的 MTurk 是一种潜在有用的调查方法，可在对受访者保密的情况下获取有关公众意见和/或知识的信息，具有成本、速度和广泛且相对较好地代表一般人群的明显优势。
There are many challenges in conducting surveys of study participants, including cost, time, and ability to obtain quality and reproducible work. Cloudsourcing (an arrangement where a cloud provider is paid to carry out services that could be provided in-house) has the potential to provide vastly larger, less expensive, and more generalizable survey pools. The objective of this study is to evaluate, using Amazon's Mechanical Turk (MTurk), a cloud-based workforce to assess patients’ perspectives of health care. A national online survey posted to Amazon's MTurk consisted of 33 multiple choice and open-ended questions. Continuous attributes were compared using t tests. We obtained 1084 responses for a total cost of US $298.10 in less than 3 days with 300 responses in under 6 hours. Of those, 44.74% (485/1084) were male and 54.80% (594/1084) female, representing 49 out of 50 states and aged 18 to 69 years. Amazon’s MTurk is a potentially useful survey method for attaining information regarding public opinions and/or knowledge with the distinct advantage of cost, speed, and a wide and relatively good representation of the general population, in a confidential setting for respondents.
