Hi, I have read through the guide (Recruiting a Custom Sample – Prolific) for recruiting a custom sample by using two surveys: one that is a set of screener questions and the second that is only available to those who fit the profile relevant to your study. I’m looking for any additional tips from researchers who have done this set-up before I start my own. For example:
- Do you have an informed consent form for both surveys or only the second one (the actual research study)?
- Do you have a rule of thumb for how many participants to open the screener questions to (e.g., x times the number you want to offer your main study to)?
- I assume that the description of the first study should state that it is a screener for a larger study and that not everyone who completes it will be eligible for the second study (but will still get paid for completing the screener). Anything else that should be included here? Or, do you have a sample screener that you’d be willing to share?
- Anything else that is important to keep in mind or that you wish you had known before doing your first study like this?
Thanks in advance!
