Replication Data for: Are Mechanical Turk worker samples representative of health status and health behaviors in the U.S.?

A cross-sectional survey comprised of questions from the nationally-representative 2014 Behavioral Risk Factor Surveillance System (BRFSS) and 2014 National Health and Nutrition Examination Survey (NHANES) was administered to 591 MTurk workers and 393 masters in 2016. Health status (asthma, depression, BMI, and general health), health behaviors (influenza vaccination, health insurance, smoking, and physical activity), and demographic characteristics of the two MTurk populations (workers and masters) were compared to each other and, using Poisson regression, to a nationally-representative BRFSS and NHANES samples.

本研究采用横断面调查设计，整合了具备全国代表性的2014年行为风险因素监测系统（Behavioral Risk Factor Surveillance System, BRFSS）与2014年全国健康与营养检查调查（National Health and Nutrition Examination Survey, NHANES）的问卷条目，于2016年面向591名MTurk平台众包工人及393名MTurk大师级工人开展调研。研究对两组MTurk人群的健康状况（涵盖哮喘、抑郁、身体质量指数BMI及总体健康水平）、健康行为（涵盖流感疫苗接种、医疗保险覆盖、吸烟行为与体育活动情况）及人口统计学特征进行了组间两两比较，并通过泊松回归（Poisson regression）将两组样本与全国代表性的BRFSS及NHANES样本开展对比分析。
