Hi roulishollandais,
The introduction page says that the survey is targeted at commercial pilots who fly and are based in Europe.
It aims to assess the current safety culture for pilots in Europe and to validate a safety culture tool in order to measure it reliably.
This is the first study that attempts to look at pilot safety culture across the whole of Europe. It is by far the largest survey on this topic to date and is quite an undertaking.
It is run by an independent body (The London School of Economics) so it has no ulterior agenda.
Internet forums will only achieve so much. If you're a European pilot take 10 minutes to submit your opinion for scientific judgement and exposure.
