Hi
As part of research commissioned by the BBC/Channel 4 (into disabled
people's representation and access to mass media) a survey of disabled
people in private households is being conducted in the UK. The
consultants on the project are very interested to hear about
sample/survey designs used in other disability surveys in order to
inform their work.
Any comments on the following proposal would be warmly welcomed.
Specific details of sampling designs used in other studies would be
particularly welcome.

Subject: Quant research with DDA disabled sample
<SNIP>
"We are looking at a sample size of around 500. The current methodology
is using face-to-face door-to-door interviews. Interviewers will be
given a set of addresses drawn randomly and ask to speak to one person
per household. We'll use the standard DDA question to filter
participants so our sample is just people who count as 'disabled' under
the DDA.
What we could really do with your advice on is:
1) Overall - does this feel sensible to you
2) How to select sampling points. The plan is to select a number
of sample points than use a random walk from those spots. Do you have
any advice on the number of sample points to select? Or how to select
them?
3) The impact of filtering at the door - are we likely to fail to
get more severely disabled people?
4) Setting quotas - I think we will probably want to set quotas in
terms of age, class, and perhaps severity. This will allow us to weight
the data to the national profile. Does that make sense? And do you have
any advice on setting those quotas?"

Best wishes
