There is something on this. It was pointed out to me when doing a study with
pain as an outcome measure. We used a 100mm visual analogue scale (like just
about everyone else), but used it horizontally. This is said to favour a
mark dependant on the handedness of the individual. If low scores are on the
left (the usual way) left handers favour a lower score than right handers. I
don't have the original papers to back this up but it does make sense.We now
use, and would recommend vertical VAS (though it tends to make your data
collection forms bigger!).
