How can I find out whether I am permitted to re-use an online questionnaire in my own research? 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.
The script doesn't seem to have a license but says, "question.cgi is a free script for administering user interface usability questionnaires on the web." In other places on the page you linked to, the authors encourage reuse. If you are unsure or unclear, you can contact the authors.
