Does anyone know of a good Spanish translation of the System Usability Scale (SUS) survey? Unfortunately I'm not a Spanish speaker myself however am testing with people who are. A solid resource of different language versions would be great if such a thing exists.
Also, more broadly; as I understand it the language for the SUS survey (english) is very well calibrated. What are the pros and cons of using a different language version? Is it scientifically valid to line up the German language answers against the English language answers?
