I recently discovered something that may be problematic. The first button of a scale response questionnaire is always recorded as a "1". For example, suppose I have a 0-8 likert scale and I create a questionnaire in media lab. I set the labels of the questionnaire to range from 0-8. However, in actuality MediaLab records people's answers as ranging from 1-9. So even if the label on the screen appears as a "0" media lab records the first icon as a "1" regardless of its label. This is problematic for people who later on assume that the data ranges from 0-8 when in fact the data ranges from 1-9. This is also an issue when people try to reverse score questionnaire items in analyses.
