Hey there,
luckily, our fellows from the Max Planck Institute have now reacted to this request and acutally designed an english questionaire.
As this was also a bit of work by them, and to support them for what they do for us I would ask you not only to fill it in, but also share it with everyone you know who slept polyphasically once.
Thank you so much.
I think this is something where we can really bring the research on polyphasic sleep forward, therefore I want to give them all the support I can.
Cheers
Marcel
