First time collecting data on Prolific!
I downloaded the Prolific demographic data for my study, and I am concerned that some of the demographic data is missing. There are some cells for ‘age’, ‘student status’ and ‘employment status’ that contain ‘DATA_EXPIRED’. I don’t care about student/employment status, but age is a pretty essential piece of demographic info!
We didn’t include basic demographic questions like age in the study, because Prolific states clearly that these are included by default. Is there are way to recover this missing data, either by contacting Prolific, or participants directly?
What does it mean for such data to be “expired” and how can I prevent this happening in the future? If I set prescreen filters for things like age and simply include the full range/all possible options, will this prevent me from recruiting people with DATA_EXPIRED for these variables? Or is it better to just ask for key demographic data within my own surveys/experiments to ensure this information is captured?
Thanks in advance for your help.
