Second eFramngham Heart Study

Completed · Not applicable

Conditions studied: Cardiovascular Diseases

In brief

In the electronic Framingham Heart Study (eFHS), the investigators developed and deployed a mobile app to collect cardiovascular risk factors and event data and test them against cardiovascular data collected in the Framingham research clinic for the FHS. Participants enrolled in eFHS receive a series of digital surveys modules to complete on a regularly occurring schedule. The objective of the planned randomized trial is to test the effect of administering half of survey modules every 2 weeks versus all survey modules every 4 weeks on improving participants' response rates. There will be 4 survey periods. Period 1 encompasses all survey modules administered from baseline up to week 8 (19 surveys/tasks per participant); period 2 from week 8 up to week 16 (18 surveys/tasks per participant); period 3 from week 16 up to week 24; period 4 from week 24 (16 surveys/tasks per participant).
