I would like to ask, what if the original English instrument will be given to respondents of a country that also used English language, what cross cultural validation steps should I undertake?
to see the construct validity of the instrument, it should be validated by a panel of experts to be reviewed and revised. validation is not necessarily related to the language. it wants to be sure whether it measures the construct purported to be measured. best regards
If you use an instrument that has already been peer-reviewed, you do not need to start at the beginning to validate it, because it was already validated in the original publication. If you make changes, then you should take steps, such as Farangis suggested, to validate the changes.
Thank you so much for all your responses. In addition to your responses, I learned that I need to perform an exploratory factor analysis and correlate it with the result of EFA in the original instrument.
