Dropout in a Longitudinal Survey of Amazon Mechanical Turk Workers With Low Back Pain: Observational Study

Dropout in a Longitudinal Survey of Amazon Mechanical Turk Workers With Low Back Pain: Observational Study

Additional detail on data collection of wave 1 data is described by Qureshi et al [13]. All participants provided electronic consent at the beginning of the survey. Those who completed general health and back pain surveys at wave 1 were offered US $3.50 for their participation. Participants were offered an additional US $5 per subsequent completed survey (wave 2 and wave 3). All baseline participants (even those who did not participate in wave 2) were asked to participate in wave 3.

Effects of Excluding Those Who Report Having “Syndomitis” or “Chekalism” on Data Quality: Longitudinal Health Survey of a Sample From Amazon’s Mechanical Turk

This study extends the work of Qureshi et al [5], by examining improvements in data quality and effects on mean estimates of health status by excluding respondents who endorse either or both of 2 fake health conditions (“Syndomitis” and “Chekalism”). We developed web-based surveys and used the web-based platform Cloud Research (formerly Turk Prime) to field the survey in 2021 with MTurk participants [11].
