Translation
If you are interested in translating any of these tools we recommend that the original scale be translated by two independent translators. The two translations should then be compared, and differences resolved. A process of cultural adaptation may then be needed, e.g. using a focus group of professionals or users. Finally, the scale should be translated back into English, again using two independent translators, and the results compared with the original.
