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.
