Amazon Mechanical Turk（MTurk）作为一种方便的收集人类受试者的方法，越来越受到研究人员的关注，因为它在保护数据样本方面效率高、成本低、易于使用。目前的研究提供了三个独立的MTurk样本的荟萃分析审查。参与者是从亚马逊MTurk系统招募的1707名美国公民（774名男性和933名女性，年龄在18-77岁之间）。结果表明，在三个MTurk样本中，工人的人口统计特征在性别和种族上与美国普通人口非常接近，但由于无神论者和不可知论者的数量非常多（38.3%），因此在宗教信仰上存在差异。在三个样本中，15个研究量表中的14个观察到显著的平均水平差异;然而，效应量很小（eta（2）范围为0.01至0.04）。结果表明，在人格和灵性领域工作的个人需要意识到，使用MTurk样本可能会在他们的数据中引入样本偏差。
Amazon Mechanical Turk (MTurk) has increasingly attracted the attention of researchers as a convenient method to gather human subjects due to its efficiency, low cost, and ease of use in securing data samples. The current study provides a meta-analytic review across three separate MTurk samples. Participants were 1707 US citizens (774 males and 933 females, aged 18-77 years) recruited from Amazon's MTurk system. Results indicated that across three MTurk samples, demographic characteristics of workers closely approximated the general US population on gender and race but differed on religious affiliation given the very high number of Atheists and Agnostics (38.3%). Across the three samples, significant mean level differences were observed for 14 of the 15 study scales; however, effect sizes were small (eta(2) ranged from .01 to .04). Results suggested that individuals working in the fields of personality and spirituality need to be aware that using an MTurk sample may introduce sample bias in their data.
