FeelSync: Tailoring Ecological Momentary Assessments and Interventions for Emotion Awareness, Regulation, and Mental Health Outcomes

This study investigates how different ways of reflecting on emotions in daily life influence emotional awareness, emotion regulation, and mental health. Using the FeelSync mobile app over the course of seven days, participants are prompted multiple times a day to report on their current emotional state in various formats (e.g., rating scales, multiple choice, or free text). In some groups, participants also receive brief daily exercises designed to help them practice cognitive reappraisal-a strategy that involves reframing stressful situations to reduce their emotional impact. The study aims to assess not only the overall effectiveness of these reappraisal exercises but also whether the type of emotional self-report used before the intervention affects its impact. All participants complete questionnaires before and after the app phase to track changes in mood, stress, emotional awareness, and regulation.
