Dear Sir.
I am Miss Aungkana Petkan from Faculty of Medicine Siriraj Hospital, Mahidol University Thailand. Are interested in the Speilberger interview (State Trait Anxiety Inventory), which has two parts: a "trait anxiety" and "state anxiety" for the measurement results in the research ; total 128 volunteers .
In preliminary estimates, royalties were found to be paid $ 140.80. However, I wish to take a trait anxiety part only. So the inquiry concerned whether there will be opportunities to reduce these expenses?
Thank you. I’m waiting for your reply.
Best Regards.
