I wrongly approved two submissions of participants who timed out from my survey. The participants were paid for this and there is no way for me to undo my mistake. Would Prolific be able to retrieve the wrongly approved payment?

Hey Adam, welcome to the community!

Since we’d need to discuss participant IDs to resolve this, it would be better if you send a support ticket to our team.

Message me with your support ticket number and I’ll make sure it’s prioritised :slight_smile:

I have some money left over from a previous study and set up another study to use this, but I have problems publishing the study. An error shows up, that says I have to top up my account in order to publish, but I have the required total sum in my account.


Hi Fozia, welcome to the community! It’s great to have you here :tada:

That’s probably due to a discrepancy between your total and available balance.

Your total balance is the total amount of money in your account from the top-ups you’ve made, minus any funds spent on participant payments. Your available balance is how much you will after any active studies have been completed.

So, it’s likely that your total balance is showing that you have enough, but your available balance is not enough because some of your money is reserved for an active study on your account. You can read more about this here.

And you can check your different balances here.

Does that help? Let me know if I can help further!

It helped, thank you!

HI there,

My colleague and I are thinking about doing a survey study with parent-child dyads. I have found your answer about studies on couples very helpful (Running studies on couples – Prolific). But I wonder if this two-study setup can be applied to a parent-child dyad, where the child might not necessarily have the Prolific ID. Mant thanks in advance!


I am interested in collecting data from 3 different groups of people. I would have all of the three groups do the same task. Is the best method for collecting this data to design 3 studies in prolific, one targeting each group, and send them all the same experiment (for example, I could create one study on prolific, duplicate it in drafts twice, and adjusting the filters accordingly)? Or is it best to just run one study in which the filters target all three groups at once?


Hey Anthony, welcome to the community!

Unfortunately, we won’t be able to support your study as all participants on Prolific must be at least 18 years of age. Recruiting children, even with their parents present, is against our current company policy. For now, we would recommend seeking alternative sources of participant recruitment for this research, and you may wish to explore how others in your field are going about this via the forum or ResearchGate. Sorry that I don’t have better news.

And when you have time, introduce yourself to the community :slight_smile:

Hey there! Welcome to the community! It’s great to have you aboard.

Yes, the first method you’ve described is the best way to go about it. The second method won’t get your desired result.

Is there any crossover between the groups? If so, don’t run the studies concurrently as we’re unable to stop participants from completing more than one of your studies. To ensure nobody does this, use our custom blocklist feature.

Let me know if I can help further!

Hello, I am an academic researcher and would like to know how much Prolific costs per survey respondent?
Thank you so much!
