No previous study used large-scale data from many countries on a topic- can this be a strong rationale for a study? for instance, if I say that there is no previous cross-national study on a topic so it cannot be said that it is a worldwide phenomenon rather than a specific regional phenomenon. Also, a cross-national study will give the result a stronger generalization power which might of interest to international practitioners like WHO.
- Can these statements be a strong rationale and justification for a study? Please let me know, Thank you.
