Whenever I start a new research project, I have to dig through innumerable survey questions to find rating scales that other projects found sensitive enough to get statistically valid results. The only standard psychological measures are very expensive and usually pertain to mental illness.
I generally end up copying existing surveys, although this is generally considered fair use I don't care to dance around copyright. Is there a StackOverflow/PatternLibrary/Best Practices compendium of this sort of information?
Maybe StatExchange can be used for this...
