I want to use one questionnaire to measure health literacy in different countries. In order to reduce the measurement variance in international comparison, a metric invariance would be the aim.
I too, wished to study Cancer Health Literacy in Indian patients. However, the only instrument developed thus far has come out of a study in the USA. This questionnaire is completely out of context for the Indian population. This should be taken into consideration if a single instrument is to be used across multiple countries.
Here are some of the resources that will help evaluating the measurement invariance of your instrument:
In Asian context, you could be referred to HLS-EU-Q47 or HLS-SF12. These tools have been validated in several Asian countries in general populations, patients in general, cancer patients, and stroke patients. A group of researchers in Manipal are conducting health literacy survey using these tools.
