EMI for Reducing Psychological Distress in Young Adults With Multiple ACEs: A Feasibility Study

This single-arm feasibility study aims to evaluate the feasibility and acceptability of an ecological momentary intervention (EMI) designed to reduce psychological distress among young adults with high levels of adverse childhood experiences (ACEs). The intervention targets three potentially modifiable transdiagnostic psychological processes: emotional clarity, self-esteem, and catastrophizing. Approximately 20 young adults aged 18-29 years who have experienced at least two types of ACEs and report elevated psychological distress will be enrolled. All participants will receive a 2-week smartphone-based EMI delivered in daily life. Feasibility, acceptability, and safety will be evaluated using recruitment, retention, intervention use, participant satisfaction, perceived burden, and adverse events. Changes in psychological distress and related psychological outcomes from baseline to post-intervention will also be explored as exploratory outcomes.
