This research study is being done to better understand how people experience stress in everyday life and how that stress may relate to sleep and physical activity. We are also testing stress management approaches that are intended to reduce stress responses in everyday life.

This study asks participants to carry and use a study-provided smartphone to answer brief surveys during daily life for several weeks. On these surveys, participants will self-report their stress, mood, thoughts, physical activity, and sleep patterns, as well as a few other questions about where they are and what they are doing at each survey. Study participants will also wear two commercial devices on their person; one that tracks physical activity and the other sleep. Information about stress management will also be provided to participants on the study smartphone. At the end of the study, participants will be asked to return the smartphone and devices and will receive compensation for their time and effort.

The overall aim of this study is to determine the effectiveness of two stress management interventions, both delivered via the study smartphone, on the outcomes of stress responses, sleep, and physical activity.
