She also compared people questioning the methodology to people not believing what women say about VAWG which I thought was a bit off.
I totally agree with her. That's what it comes across as - "this can't possibly be true, it must be bad science". We have had comments to that effect on this thread.
I think you misunderstand. The work she has done is great for looking at for eg relationships between ethnicity or religion and abuse. It is great for looking at types of abuse and their relative prevalence. It's is great for seeing how young girls as well as adult women are subjected to abuse. No-one on this thread has questioned that.
What it cannot do is say 99.3% of UK women have experienced sexual abuse, or any other extrapolation of the general population. It can say that 99.3% of people recruited to a survey using the words "collect experiences of UK adult women subjected to any form of violence and abuse since birth" have indeed experienced abuse.
Anything collected within the survey is perfectly valid, and will give some very useful information. It just can't be extended to the female population as a whole (just the female population who has experienced abuse) which is a shame as it would be nice to know how much overlap there is.
If only the survey had recruited using a more neutral phrase eg "collect experiences of UK adult women who both have and have not experience abuse or violence".
