What if people lie just to get the $25?"
Thanks for responding. I fully expect there to be liars. Every questionnaire, no matter what the subject matter, tend to have people respond untruthfully. It is expected by all researchers. There are analyses that can (and will) be performed on the data to weed out these responses.
One possible example (there are several tests), if most people respond to a question with "Strongly Agree" because they fit the behavior patterns of an addict, then if someone responds to "Disagree" or "Strongly Disagree", they are considered an outlier. If this happens multiple time (which it would likely do), that person is removed from the dataset. This is one reason I need so many people to respond. The more responses gathered, the more likely it is to find a trend and spot liars.
