This study is developing novel ways to assess symptoms of depression in patients being treated for depression using wristband devices and smartphones. This study lasts for up to 12 weeks and will involve weekly virtual (phone call or video call) visits. You will be asked to wear wristband devices on both wrists for 12 weeks, which will be used to measure physiological changes. We also ask that you fill out surveys and complete short vocal tasks on your phone. This study has the potential to revolutionize the way people with depression are monitored long-term. You will be paid up to $1069 for your participation, depending on which parts of the study you complete.
