The problem with these Likerts is that they are often an uncalibrated scale, so the subject is interpreting the question as well as the possible responses. They are also used in medical studies of pain, for example. You've seen them- the little faces in the doctor's office indicating differing amounts of discomfort and you pic the one that describes you). My buddy and I had a good laugh thinking up how to calibrate it :)

I'm not even sure how you test something like that for reliability.
