UAS EMA description

For this project, you are invited to participate in all or some of several activities. These consist of a once-a-month survey, as well as the potential for being enrolled in an intensive 7-day study where you would wear an activity tracking device similar to a wristwatch every day, and answer questions using an app on your cellphone each day. Each evening of that 7-day study, you would also fill out a survey online and record information about your day using the phone app. On the eighth day you will send us the device, and fill out a final online survey.
