For the record, I don't think this is very accurate. In this blurb, health psyc is being favourably compared to something they have called "traditional psychology", which is supposed to be based on a psychodynamic model. That sounds more like "nineteenth century psychiatry" to me. Also, I've seen the content of a few Health Psyc programmes, and they definitely cover BPS type stuff - reducing "pain catastrophising" and stuff like that. So this blurb doesn't accurately reflect what Health psychs are actually being taught.
A quick look at their flagship journal "Health Psychology" and you'll see what I mean (includes papers by Wearden, etc).
