I've filled it in but it does make quite a lot of assumptions and you don't collect data for how many births people have had and whether it was 1st, 2nd, 3rd, 4th baby a hb was planned - which is useful to know when analysing your data.
I've had 2 homebirths so it was difficult to fill in because it assumes only one but I had a go! I couldn't answer Q3 because it was biased towards negative experience nor Q5 because I didn't have a specific midwife.
Just in case it's useful...
More people attempt homebirth than actually have one. Most are transferred in for "failure to progress". So you might plan one but not get one.
Not everybody has a caseload midwife (Q5) so there may not even be a discussion about home birth and if you did have one you may not have seen that midwife again! Quite shocking really. I'd never met any of the 3 MWs involved in dc2's birth and only 1 of the 2 from dc1's prior to labour.
"Too far" is rarely given as a reason by HCPs not to do homebirth. Have a look at the stats for Wales and Cornwall. Distance to hospital is longer but hb rate much, much higher than UK average.
If you want to know more about homebirth look up AIMS and NCT. Also do read this article. She influenced my decision hugely.
Good luck with your studies :)
