Study of Student Flourishing

The goal of this study is to learn how a science-based mobile app, called Flourish, affects student well-being. The main questions it aims to answer are: 1. Does receiving access to the Flourish app increase well-being (e.g., positive affect, loneliness, belonging) among students? 2. Does using the Flourish app in combination with a human buddy/friend lead to better outcomes than using the app alone? Researchers will compare three different groups to see if and how the Flourish app works to improve student well-being: 1. Waitlist Control Group: Students continue with existing school resources. 2. Flourish App Group: Students use the Flourish app (a digital toolkit and AI chatbot) twice per week. 3. Flourish App + Buddy Group: Students use the Flourish app twice per week with someone else as a \"Flourish Buddy\". Participants will: Be randomly assigned to one of the three groups listed above. Use the app or continue with regular resources for 6 weeks. Complete four short online surveys about their well-being (at the beginning, during the 6 weeks, and at the end).
