Does anyone know how ethics approval works if we work for a university outside the UK?
Do we need ethics approval from a UK committee or is approval from our local committee sufficient?
That will depend on your local ethics committee… Or rather, I think you only need approval from your local ethics committee (unless they should stipulate that others be involved).
Prolific also has its own ethical guidelines such as paying a sufficient amount.
And that privacy is maintained
And the Prolific study design guidelines are ethical all over.
