Epworth and other sleepiness scales?
What are the common questionnaires used to quantify sleepiness? I have the impression the Epworth sleepiness scale (ESS) is the defacto standard with how common it seems to be, though I have also encountered the Pittsburgh sleep quality index (PSQI). Those are the only two I know about. What else is out there?
Are these things only used in research? Was anybody here given a questionnaire before getting a diagnosis?
