Actually , I have already sent email to you but I'm not sure that you get an email from me or not, so I send it again. After I read your publication name “The Cognitive Appraisal of Health Scale: Development and Psychometric Evaluation”, I am very interested in your instrument named “The Cognitive Appraisal of Health Scale”. I plan to use your instrument to measure “cognitive appraisal” which is one of the independent variables in my study. Therefore, I would like to ask for your permission to use the CAHS, which translated into Thai language by Lawan Toontong (2011) in my thesis.
