Absolutely. Why do you think so many people are sick. I was sick almost everyday from the time I was around 6 years old up to around 13. It got me out of school. I know people are are 'professional' sick people as sick as that sounds.
Yeah, there are a couple of classified "disorders" around that... hypochondria, etc...
There's a fair amount of information about placebic effects (which go both ways) in a book called Predictably Irrational by MIT professor of behavioral economics Dan Ariely. I've actually done a bunch more research on that subject -- there are a whole range of physiological effects from anxiety that can produce legitimate injury in the body, not to mention ret*d healthy brain development even in adults. The reverse is also true of positive emotional states (which you can also train yourself to experience more often). Check out some work by a woman named Frederickson - "the undoing effects of positive emotions" -- she's developed a body of work they're calling a "broaden and build" model. In the undoing effects study she first has to describe a number of the physiological effects of negative emotions that they were testing for reversibility.
