EMI for Reducing Psychological Distress in Young Adults With Multiple ACEs: A Feasibility Study
tiistai 15. syyskuuta 2026 päivittänyt: Yinyin Zang, PhD, Peking University
Ecological Momentary Intervention for Reducing Psychological Distress in Young Adults With Multiple Adverse Childhood Experiences: 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.

Kokeellinen: EMI intervention
EMI intervention targets three potentially modifiable transdiagnostic psychological processes: emotional clarity, self-esteem, and catastrophizing.
The intervention includes brief ecological momentary assessments and tailored exercises addressing negative and positive emotional experiences.
|
The ecological momentary intervention (EMI) is a 2-week smartphone-based intervention delivered in participants' daily lives. At the beginning of the intervention, participants will watch an approximately 10-minute psychoeducational video introducing the psychological principles underlying the intervention and the purposes of the exercises. They will then receive instructions on how to use the EMI program. During the intervention period, participants will receive brief ecological momentary assessments (EMAs) assessing their current emotional state. Based on their reported emotional valence, the program will provide tailored intervention content. When participants report negative or neutral emotional states (emotional valence ≤ 0), they will receive a negative-emotion module. This module includes brief breathing and grounding exercises, identification and labeling of current emotions, identification of potentially catastrophic or negative self-referential thoughts, cognitive reapprais |

Intervention acceptability
Aikaikkuna: Immediately post-treatment
|
Intervention acceptability will be assessed using an adapted version of the Chinese Acceptability of Intervention Measure (cAIM).
In addition to the original cAIM items, the adapted measure includes items assessing participants' willingness to recommend the intervention to friends and their willingness to continue using the intervention, informed by Wang et al. (2024).
All items are rated on a 5-point scale from 1 (completely disagree) to 5 (completely agree), with higher scores indicating greater perceived acceptability of the intervention.
