“​Somewhat confusingly, satisfaction scales also have a subgroup called satisfaction scales. I’ve broken this group into three further subgroups (unipolar rating scales, unipolar thermometers, and bipolar rating scales) as some research suggests that they have different reliability and discriminating characteristics.
