Smartphone-based Mindfulness Training for Health Following Early Life Adversity
In Brief
A Phase 1 clinical trial evaluating Mindfulness and Coping for Stress and 2 related conditions. Completed, enrolled 81 participants across 1 site.
Detailed Summary
This study will test the feasibility of delivering smartphone-based mindfulness and coping interventions to a sample of emerging/young adults with a history of early life adversity (ELA). 80 participants with a history of ELA will be randomly assigned to complete a two-week mindfulness training intervention or matched coping control intervention, both involving 14 foundational audio-guided lessons and practice prompts randomly delivered 3x daily. At baseline, post-intervention, and one-month follow-up lab assessments, participants will complete questionnaires and provide blood samples for assessment of markers of inflammation. Data assessing subjective and physiological stress in daily life will be collected during the intervention and for one week before, immediately after, and one month after the intervention. Passive sensor data will be continuously collected from participants' smartphones and wearable devices to develop exploratory models that estimate and predict daily life stress. Data will be used to evaluate feasibility and acceptability of interventions and assessments in an ELA sample, test effects of mindfulness training on daily life stress and markers of inflammation in an ELA sample, and develop exploratory machine learning models of stress from passive sensor data.

Timeline
Interventions
The mindfulness intervention includes 14 daily 20-minute audio lessons plus brief daily practice prompts. Lessons train specific meditation techniques through didactic explanation and guided practice. Based on the Unified Mindfulness system, lessons train 3 mindfulness skills: concentration, sensory clarity, and equanimity. Concentration, a state of stable attention on the intended target, enables participants to monitor present-moment physical and emotional body experiences. Sensory clarity, the monitoring of momentary experiences, involves detecting subtle sensations and discriminating between different experiences. Equanimity, an attitude of acceptance toward momentary experiences, is trained through 3 strategies: (a) body relaxation, (b) mental welcoming, and (c) a gentle tone of voice. Practice prompts build on the skills trained in each lesson, encouraging participants to practice brief moments of mindful awareness, mindfulness while doing daily tasks, or formal meditation.
The coping intervention includes 14 daily 20-minute audio lessons plus brief daily practice prompts. Lessons train specific coping techniques through didactic explanation and guided practice. Lessons train coping skills (reflection, reappraisal, and problem solving) without encouraging focus on or acceptance of present experience (i.e., mindfulness skills). Participants are instructed to: (1) reflect and let their minds drift, (2) reframe or reappraise past and anticipated events, and (3) analyze and solve personal problems. Practice prompts build on the skills trained in each lesson, encouraging participants to take brief reflection breaks or to practice reappraisal or problem-solving skills.
