Here's a video from the Health foundation about it.

There are two "Tackling stigma" campaigns you might be interested in. One is "Time to Change" from England. They have a range of great materials. (I've had some minor involvement with a Time to Change project): http://www.time-to-change.org.uk/
The other is the Australian "Soften the Fuck Up": http://softenthefckup.spurprojects.org/
Good luck! I'd be really interested to hear about the results.
