My doctorate is a cross-cultural study between Spain and Japan. That is why my colleagues and I are adapting to Japanese the ICQ-15, which is a questionnaire that evaluates communication. It is very short, only 15 items, so it will take less than 2 min to fill it.
It would need Japanese population to fill it. It only requires participants to be between the ages of 18 and 40.

If you could spread it among your contacts, I would appreciate it. Thank you very much in advance!
