This page gives you information to help you decide whether or not to be in this research study.
Being in the study is voluntary. Please read this carefully. After doing so, you can decide
whether or not you want to be in the study.
The University of Washington is recruiting 25,000 participants, age 19 and over, to participate in
a research study funded by the Department of Defense to determine if smart phones can help
track and predict outbreaks of infectious disease including but not limited to COVID-19, cold,
and flu, and head injuries. We are recruiting participants to use a mobile phone application for 12
weeks to collect data from surveys and information from your phone, such as location
information (see information we collect listed below). You will receive up to $90.00 in Amazon
gift codes for completing the surveys and allowing access to some passive sensor data.
We will ask you to download the free study application to your phone. In the application, we will
ask you questions about your health, mood, physical activity, and smart phone usage every day
over the course of 12 weeks.
After downloading the application, you will be asked to complete a baseline survey about your
health history, mood, physical activity, and phone usage. The baseline survey should take
between 5 and 10 minutes to complete. You may also be asked to stand or walk during this
assessment. You may also be asked to provide a voice sample by reading a sentence, take a
picture of yourself, and take a video of yourself.
In order for us to keep the study running safely, we require that all participants respond to
a limited number of questions during the baseline survey (e.g. zip code, state, height, weight) and
that all participants allow the app to collect passive data from the accelerometer and gyroscope.
Along with other verification techniques that you may be asked to complete (e.g. identifying images,
entering a random sequence of letters and numbers), these measures help us to ensure that the study
continues to run safely. Other than these limited questions at the baseline survey and these two
passive sensors, you may refuse to answer any question and/or may withdraw permissions for other
passive data collection at any time.
During the 12 weeks, you will be asked to answer daily questions about your mood, physical
activity, and phone usage. These daily questions take between 2 and 7 minutes to complete.
Examples of these questions include:
- How difficult was it to fall and stay asleep last night?
- What best describes your activity level yesterday?
- Do you have a sore throat?
During the 12 weeks, you will also be asked to provide voice samples, photos, and videos of
yourself. These images and videos will be of your eyes which helps us collect information about
head injuries. You can say yes or no each time you are asked. Even if you say no, you can stay in
You are also asked to allow the application to collect passive data from your phone and
potentially other wearable devices you may already use (e.g., fitbits) during the 12 weeks
through your phone’s or wearable devices’s sensors. Passive data includes but is not limited to device
movement, location, and status, including whether the device is in active use, connected to a data
network, and environmental information including ambient light, temperature, and humidity.
Location information includes the device’s actual location (for example, latitude and longitude)
as well as the device’s location relative to set points (for example, distance from a specific cell
phone tower). Location information also includes proximity information, including how close
you are to someone else that has downloaded the app. With your permission, the app may alert
you if you have been in close contact with another app user that has reported being diagnosed
with an infectious disease including but not limited to COVID-19, cold, and flu, or if you have
been to a location with a known outbreak of an infectious disease including but not limited to
COVID-19, cold, and flu. If you give permission, location information and other passive data are
collected continuously, not just when the app is open. You can say no to providing location
information and/or passive data and stay in the study, with the exception of accelerometer and
gyroscope. All of the information you provide is kept confidential, and we are not able to
identify you based on the information provided.
At the end of the 12 week study, we will ask you to complete a survey to provide us with
information on your experience in the study.
As we mentioned above, we require that all participants respond to a limited number of questions
during the baseline survey (e.g. zip code, state, height, weight) and that all participants allow
the app to collect passive data from the accelerometer and gyroscope. Other than these limited
questions at the baseline survey and these two passive sensors, you may refuse to answer any question
and/or may withdraw permissions for other passive data collection at any time.
You will receive up to $90 for completing the baseline and follow up surveys. You will be paid
monthly, and the final amount you are paid will be based on the number of surveys you completed
during that month and whether passively collected smartphone sensor was uploaded from your app.
You will receive an Amazon gift code via the email that you provide during registration.
Risks, Stress, or Discomfort
Answering questions about your mood, physical activity, and phone usage may make you feel
uncomfortable or frustrated, which may impact your mood. You may refuse to answer any
question at any time, with the exception of a few baseline survey questions.
We will do our best to protect your confidentiality but there is some risk that people outside of
the research could find out that you participated, which may cause distress. The data collected
through the application is encrypted on the phone. This means that your data is protected. All
data collected is kept on secure servers separate from any identifiable information. The account
information provided when you download the application will not be stored with survey
responses or sensor measurements. Participation in research is voluntary and you may refuse or
discontinue with no penalty.
Alternatives to Taking Part in this Study
Participation in research is voluntary and you may refuse or discontinue with no penalty.
Benefits of the Study
There will be no direct benefit to you from participating in the study. However, the information
that you provide may help researchers to better understand if mobile phones can help to know
when someone will get sick and/or when someone is experiencing effects of a head injury.
Not Medical Care
This is a research study. There is no doctor or healthcare professional monitoring your responses.
Although we are interested in detecting flu outbreaks and the consequences of head injury, we
are not health care professionals. If you have any concerns about your health, please contact your
primary care doctor.

Confidentiality of Research Information
All of the information you provide will be kept confidential, and we are not able to identify you
based on the information provided. The data collected through the application is encrypted on the
phone. This means that your data is protected. All data collected is kept on secure servers
separate from any identifiable information. The link between your identifiers and the research
data will be destroyed after the records retention period required by state and/or federal law. The
account information provided when you download the application will not be stored with survey
responses or sensor measurements. Image, proximity, and actual location data are stored
separately from all other sensor data and would be inaccessible in their raw forms from the
people accessing the data. That means that the people who view the data would not be able to see
the images or videos that you have uploaded, or see where your device is or has been. This data
includes changes in eye movement, pupil activity, and size, which allows researchers to learn
more about head injuries. This data is converted automatically by a program that extracts data
from the images without a researcher looking at the picture or video.
Government or university staff sometimes review studies such as this one to make sure they are
being done safely and legally. If a review of this study takes place, your records may be
examined. The US Department of Defense, the sponsor of this study, will have access to research
records to ensure protection of research participants. The reviewers will protect your privacy.
The study records will not be used to put you at legal risk of harm.
Use of Information
The information and/or data that we obtain from you for this study might be used for future
research. We will remove anything that might identify you from the information and data. If we
do so, that information and data may then be used for future research studies or given to another
investigator without getting additional permissions from you. It is also possible that in the future
we may want to use or share study information that might identify you. If we do, an independent
review board will decide whether or not we need to get additional permissions from you.
There are no costs to you for participating in the study. However, transmitting data collected in
the study may count against your mobile data plan. You may change the application to only use
Wi-Fi connections to manage how this data collection will affect your plan.
You may refuse to participate and you are free to withdraw from this study at any time without
penalty or loss of benefits to which you are otherwise entitled.
In return for your time and effort, you will receive up to $90.00 in Amazon gift codes for
completing surveys and allowing some passive sensor data collection throughout the study.
