In brief

The project will enroll up to 10,000 adult volunteers in individualized experiments (N-of-1 trials) designed to assess the individual-level effects of any of five interventions on three outcomes. The five interventions are: gratitude journaling, mindfulness meditation, random acts of kindness, physical activity, and laughter therapy. The three outcomes are stress, cognitive focus, and happiness.
