So, I get this page's link: User Interface Usability Evaluation with Web-Based Questionnaires from my friend. I want to make one of them as Questionnaire for the design I made for Academic Research. But I'm confused, is that only an example, a guideline, or can I use the Questionnaire as it is? Is there any license for those questionnaire? I've tried to read the page, but don't really know if there's something like that.
Actually, the text on the page is pretty clear:
The script is freely available, AS-IS
So, yes, you can use it as it is.
Combine this with the (slightly) earlier text
allows the online reader to design and create their own questionnaire
and I think there is only one way to interpret this as "Feel free to use this!"
