Mycolleague and I are trying to study acculturation by Indian consumers to a global consumer culture. The scale is already identified. Our question is how and whether it is possible to cross validate the scale and its applicability in an indian consumer context? The scale is already validated in 08 countries.
You could start by looking at the original development of the scale and the evidence that those authors gave for the validity of the scale, and then replicate that. Since the scale has already be used in other countries, you could also look at the processes that those additional authors used for cross-validation.
In other words, if others have already sent a standard, you won't need to reinvent it.
As already mentioned, the previous validation process need to be studied along with the original scale development process. Obviously, a pilot study would be necessary. Usually, under such circumstances, some sort of language adaptation may be necessary to ensure clarity of content and context. Validated scales oftentimes may not require substantial changes.
For cross-validation, you can collect data using this scale. Then you can do confirmatory factor analysis using software like AMOS or LISREL. Based on the factor loadings of the items, model fit indices, RSMEA etc., you can decide on the applicability of the scale in your context.
