Summary

This study aims to evaluate the acceptability and effectiveness of a positive psychology-based ecological momentary intervention (EMI) for enhancing well-being in college students. A three-arm randomized controlled trial (RCT) will assess the impact of a dynamic EMI that delivers personalized exercises when participants' real-time affect or well-being scores fall below a predefined threshold, compared to control conditions. Primary outcomes include changes in well-being and mental health, evaluated through a mixed-methods approach combining quantitative measures and qualitative interviews.

Interventions

BEHAVIORAL

Ecological Momentary Intervention

This is a smartphone-based ecological momentary intervention (EMI) that delivers psychological exercises (e.g., gratitude, mindfulness) in an adaptive, "as-needed" manner. Twice daily, the app algorithm assesses a participant's self-reported momentary affect and well-being. If the scores fall below a preset, moderate threshold, a corresponding intervention exercise is automatically triggered. The goal is to provide personalized support at moments of greatest need.

BEHAVIORAL

Active Control

This is a smartphone-based ecological momentary intervention (EMI) that delivers the same suite of psychological exercises on a fixed schedule, regardless of the user's current state. Participants are prompted to complete all six available exercises twice daily. This intervention controls for the general effects of exposure to the exercise content and engagement with the app, allowing for a comparison with the adaptive, algorithm-guided EMI.
