@Finoa: this introduces an entirely new aspect .. my assumption was that the original question was about learning stress (for which an instrument - by Cohen - exists).
@Saba Munawar: the pdf I attached includes a questionnaire which you can use. Unless, of course, you do mean linguistic stress, as Fiona Balloch suggests.
That's what I thought. You can use the 10-item questionnaire in the pdf that I attached above. Take care that you reverse the responses as described under "Scoring". You can then compare your results with those of the norm table.
