Positive Psychology - Based EMl for Enhancing Well-Being

Positive Psychology-Based Ecological Momentary Intervention for Well-Being in College Students: A Randomized Controlled Trial

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.

This study aims to evaluate a Positive Psychology-based Ecological Momentary Intervention (EMI) designed to enhance well-being among college students. A three-arm randomized controlled trial (RCT) will be conducted to examine the intervention's effectiveness. The EMI integrates core positive psychology practices-such as gratitude, mindfulness, and acts of kindness-and is delivered through a mobile application in real time. The intervention features a dynamic, adaptive algorithm that provides personalized exercises when participants' real-time affect or well-being scores fall below a predefined threshold. Primary outcomes include changes in well-being and mental health . A mixed-methods design will be employed, combining quantitative assessments at baseline, post-intervention, and one-month follow-up with qualitative post-intervention interviews to gain an in-depth understanding of the intervention's impact and user experience.
