When using Prime Panels, TurkPrime is not able to specify the exact payment each participant receives. This is because different platforms have different ways of incentivizing participation and compensating participants for their time. For example, SurveyMonkey donates to a charity of the participants' choice. Other online panels give people gift cards, reward points, or small amounts of money.
The vast majority of the time, market research platforms leave compensation options up to the participants themselves (i.e., letting people choose between reward points, gift cards, or cash). Given that participant payments are decentralized and often vary, TurkPrime is unable to quantify exactly how much each participant is compensated.
Yes, it does. The price you receive for a Prime Panels study is the price that ensures panel providers will send enough participants to your study to reach your desired sample size. This price includes all panel fees and participant compensation, although panel providers handle participant compensation on their platforms.
Researchers or the institutional review boards (IRB) they work with sometimes express concern about not being able to specify exactly how much each participant receives for completing a study. While this is a valid concern, the decentralized nature of payments on the Prime Panels platform does allow us to identify exactly how much participant is compensated with. As is the norm for online platforms and online studies, payment is typically modest enough to alleviate concerns about coercion. In addition, allowing online participants to decide whether a study and its compensation is worth their time respects people's autonomy.
NOTE: When using Prime Panels, the language researchers typically write into their consent form and that has been approved by multiple IRB's is:
"Upon completion of the study, you will receive compensation in the amount you have agreed to with the platform through which you entered this survey."
As a general rule, the only platforms where researchers know how much participants are being paid is Amazon Mechanical Turk and other micro-tasks platforms such as FigureEight (formerly CrowdFlower). There are many differences between micro-task platforms and market research platforms in terms of culture, participant motivation, and participant expectations for studies. The key commonality is that people participate in studies based on their own free will and feel the rewards offered are worth their time.
