Can i find a newly diagnosed cancer patients to participate in my research
Hello @haifa_bin_haamed, and welcome to the forum!
You can use one of the prescreeners that Prolific provides under the section “Select participants” and then clicking “Prescreen participants”. For your case I think that the one labelled ‘Chronic condition/illness’ is the most suitable. Indeed participants were asked to reply to the question Do you have – or have you had – any condition, injury, or chronic illness? when they registered to the platform and, likely, they were asked to update this info at some point later on.
Does this replies to your doubt or you need more information? Please don’t hesitate to ask in case!
thank you for your reply. ist possible to ask the cancer participants about their stage of illness so if they are new cancer patients then they can participate but if they are treated and no cancer any more they will not be allowed to proceed with the survey, is that possible?
Yes, you can do it, you just need to go for a 2-study approach. So, you first run a “prescreening” study which identifies the participants you’d like to continue to the “real” survey. Then, you use a custom allow list to invite those participants to the second study. Talking about your specific case, you can put on the filter that I mentioned you before for your study 1, that will likely just consist in a consent form and in a question such as at what stage of the cancer diagnosis/treatment are you (this is just an example, of course make sure to formulate it in the best suitable way for your needs ). Then, you would select only those replying they are new patients for the 2nd study.
Note that you need to state it clearly from your 1st study that the whole study consists in fact of two parts, and only the eligible ones will be called to participate to study 2.
Let me know if there is any other doubt. There are a few people on the forum that have been using this approach for their research, and maybe can add up to what I said with more suggestions/insights! For example there is a cool thread that @Jessica created on the topic:
Hope it helps
