I'm affiliated with two universities: do I need ethics approval from both? Currently I'm affiliated with two universities: Nankai University in China (postdoc) and Monash University in Melbourne (adjunct).  I'm attempting to apply for ethics approval for a research project involving personal data that people post online.  I'm completely new to this.

Q: Do I need ethics approval from both universities?

It would be substantially easier for me to get approval from Monash, simply because the forms are in English and the people I'd need to discuss it with speak English.



What actually happened: I applied for ethics approval from Monash.  They were fairly patient with me, being new to the process, and it took a bit of back and forth.  Nankai University matched the conditions and dates by Monash, so I didn't have to bother with filling in paperwork in Chinese.  (And the paper was subsequently published here.)
Yes.

Or at the very least, check with both Universities' ethics boards.

I know of one instance of a post graduate student who in a similar situation got clearance from one university, but not the other, and was forced to discard their results.
