Microsoft Production Reaction Cards (doc)
The set includes 118 words which presumably you would reorganise, format and print off as individual "cards". I've never used them but I do see how the tool could be useful. My only concern is that there are too many words and it could make it unwieldy to deploy in user testing.
What are your experiences with using the MS PRCs? How did you present them to people and did you find that the list could probably be culled significantly? Can you break it down into groups and focus it at specific questions to elicit responses from that group of words? For example you could group the words relating to credibility and deploy them for questions relating to credibility: Trustworthy, Consistent, Dated, Inconsistent etc.
