Reverifying Participant Info
At Prolific, we do a lot to ensure that you get the best possible data quality. But, if you really want to be sure that your participants are who they say they are, you can run some really simple checks:
Re-ask your pre-screeners within your experiment. So, for example, if you’re targeting teachers aged 25, ask participants to reconfirm their age and their occupation. This allows you to confirm that your participants’ prescreening answers are still current and valid, and may reveal people who have forgotten their original answers to prescreening questions.
Ask difficult to answer questions based on pre-screeners. So, let’s say you’re targeting people who use a particular medicine. You could ask what brand they use, their normal dosage and at what times of day they’re supposed to take it. Then compare their answers against the accurate information about that medicine.
These aren’t foolproof, but along with the extensive work Prolific already does, they can act as extra data quality control measures.
