I have just realised that some of these questions are addressed on the victim focus website www.victimfocus.org.uk/womens_experiences_violence_abuse_study
Is this sample representative of the female UK population?
This question is common but is irrelevant, as we did not seek to generalise to the entire population from this study. The findings are relevant to this cohort of 22,419 women – and some people may make inferences from this data, but we do not seek to do so.
However, we did explore the demographics of our sample in detail and found that it was more diverse than the UK population in terms of ethnicity and religion.
Women aged 18-78 took part, but the majority of women were under 60 years old, which means it is not representative of women over 60 – and this is regrettable as this group of women are often ignored or misrepresented in research.
Our sample was also slightly overrepresented in terms of education levels and wealth.
Is there a respondent bias? Wouldn’t women who were already subjected to violence be more likely to respond?
This comment has been common since our study was announced.
This criticism is valid for pretty much every study that does not use an RCT design or random sampling technique.
All studies which call for participants of any kind will be subject to some form of limitation based on interest.
However, this doesn’t seem to have been the case, especially as the sample is so diverse and many women took part away from our social media. It is more likely that the statistics are high in this sample, because they are valid responses to the accessible items.
