Mood Study

Study FAQs

The intent of this study is to use smartphones to measure mood in real-time so that clinicians can proactively improve treatment of depression.

The study lasts 12 weeks.

Project Baseline is a broad effort to better understand health and prevent disease. The first initiative is a 10,000-person, four-year study focused on health and disease more generally. This study is a new, complementary initiative focused on measuring mood changes in real-time using smartphones. Additional initiatives will launch in the future.

You need to own and use an Android smartphone and have a Google Account or being willing to create one to participate in the study.

During this study, you are expected to keep the app running on your phone and to complete the following:

  • Rate your physical activity level and sleep every day (<1 min)
  • Rate your mood and effort required to complete daily chores / duties every other day (<2 min)
  • Complete a weekly survey about your mood and its impact on your daily life (<5 min)
  • Record a weekly voice log based on a prompt (<2 min)
  • Complete monthly surveys about your social function and life satisfaction (<15 min)

Participants are expected to spend, on average, five minutes or less every day on study tasks.

No. We will not share any information with your insurance or medical providers without your consent. You and your doctor will continue to make decisions about your care. Unfortunately, you will not be able to view or share the data collected in this study.

Data collected includes both your survey responses and phone sensor data.

We will only use this information for study purposes. Passive phone sensor data may include:

  • Environmental data, such as light and air pressure
  • Activity data, such as step count and movement
  • Location data
  • Phone usage data, such as screen, network, and battery use

Research studies suggest that these data can be predictive of mood. (Select references: Wang et al, 2014; Saeb et al, 2015; Place et al, 2017)

We take your privacy and confidentiality seriously. The data you provide will be stored in a secure, encrypted database with restricted access only to authorized study personnel. Members of the study team who need to contact you will have access to directly identifying information (your name, street address, phone number, and email). Otherwise, we'll remove this information and replace it with a code number. This study has been approved by the Western Institutional Review Board, which protects the rights and safety of research participants. Please see our Privacy Policy for full details.

This study is observational, so the mobile app is not intended to be an intervention. Instead, it will monitor and track phone data that might be helpful in predicting mood. These findings could potentially help others suffering from depression in the future.

No, you won't be able to see the data that you contribute toward this study.
