Daily Smartphone Surveys


Every six months we will ask you to use a smartphone app for 14 days to share details about your sleep, stress, pain, and any substances you use (including caffeine) that might impact your sleep. 


The app we are using is called mEMA (mobile Ecological Momentary Assessment). These instructions explain how to set up and use mEMA.


If you have any questions, please feel free to call us (859-562-0112) or email us (
