@everyone - I know we are mindful of various links being posted with no real personal introduction by the poster @gibocchia - however, I have checked this and it appears a bona-fide research project.  Goldsmiths is a constituent college of The University of London, and was established in the early 1900's

The questionnaire to be found on the link is, as claimed - research on music practice - how you practice, etc etc...   It is completely anonymous, and at the end of the questions you are asked if you want feedback on the research - and it's only then, if you DO want feedback, that your email address is requested.
