It looks like it's just a starting point to be used for future studies so they all have similar classifications and coding for surveys/questionnaires. I'm also not sure how low of a bar it is when they did a study, coded the results, creating a coding system for surveys that can be used by others, and did more research to make sure they were asking the right questions. I'm willing to bet that this is the first paper in a series of them and they'll use it to grab more grant $$ to do more in-depth research.
