I would like to conduct research with refugees who speak Arabic. I have the BSI-18, PTGI, PANAS, RSES, and SWL along with their psychometric properties for Arabic speaking peoples. If someone has translated-backtranslated and centered the PCL-5 and CES then I can use them; if not, I need to do so. I cannot find publications. Are there any conference proceedings or contacts with whom I can talk? Thank you for your help.
