Outcome  Variables  •  a  caffeine  definition  module    •  a  sleep  definition  module,  with  APIs  for  getting  sleep  data  from  

various  monitors  •  new  variables  that  take  advantage  of  mobile  (e.g.,  reality  mining)  

Scripting  study  protocols  •  e.g.,  modules  for  setting  up  an  n-­‐of-­‐1  study

scaling            (n=1)  n  

Make  the  findings  comparable  for  aggregation  •  libraries  of  standard  measures  (e.g.,  PHQ-­‐9,  PROMIS)  •  indexing  of  variables  and  results  and  to  standard  vocabularies

scaling            (n=1)  n  Need  to  describe  context  to  combine  apples  with  apples    •  who  is  “n”:  demographics,  important  clinical  features  •  study  approach:  ad  hoc,  n-­‐of-­‐1,  etc.    •  activity  context:  walking?  running?  •  social  context:  …  •  technical  context:  device,  operating  system,  app,  version,  sampling  

rate…  •  etc.
