NCT05516108

Brief 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.

  • Feasibility of Adherence: Intervention Lessons

    Numbers represent percentages of intervention lessons completed in mindfulness and coping groups \[calculated as (average number of lessons completed / 14 total lessons among all participants in each group) \* 100\]. The original adherence benchmark was an average completion of \>85% of intervention lessons; reported percentages that are greater than that benchmark represent feasibility of intervention adherence.

    assessed across the entire 2-week intervention period

  • Feasibility of Safe Implementation: Incidence of Treatment-emergent Increases in Mental Health Symptoms

    Safety benchmark: \<10% of participants showing substantial (\>2SD) increases in anxiety, trauma, or depressive symptoms (using PROMIS Anxiety and Depression scales and Posttraumatic Stress Disorder Checklist-Civilian scale described in other outcomes below) combined to create treatment-emergent symptom rate

    assessed across the entire 8-week study period

  • Acceptability: Treatment Expectancies

    Acceptability of interventions, with benchmark of \>80% of participants giving positive ratings of treatment expectancies (\>3 on 6-item Credibility/Expectancy Questionnaire)

    assessed in-person at post-intervention laboratory assessment (an average of 4 weeks) and one-month follow-up laboratory assessment (an average of 8 weeks)

  • Change in Daily Life Subjective Stress: State Perceived Stress

    State perceived stress assessed in daily life four times per day for one week at three time points via Ecological Momentary Assessment (EMA), totaling up to 28 assessments at each time point. All 28 assessments at each of the three time points (pre-intervention ambulatory assessment, post-intervention ambulatory assessment, and one-month follow-up ambulatory assessment) were averaged in MLM analyses. Stress was assessed on a 1-7 Likert scale, with higher scores indicating higher perceived stress.

    change in stress assessed in daily life for 1 week at three timepoints: pre-intervention ambulatory assessment, post-intervention ambulatory assessment (an average of 3 weeks), and one-month follow-up ambulatory assessment (an average of 7 weeks)

  • Change in Daily Life Subjective Stress: Daily Perceived Stress

    Daily perceived stress assessed in daily life each evening for one week at three time points via end-of day diary, totaling up to 7 assessments at each time point. All 7 assessments at each of the three time points (pre-intervention ambulatory assessment, post-intervention ambulatory assessment, and one-month follow-up ambulatory assessment) were averaged in MLM analyses. Stress was assessed on a 1-7 Likert scale, with higher scores indicating higher perceived stress.

    change in stress assessed in daily life for 1 week at three timepoints: pre-intervention ambulatory assessment, post-intervention ambulatory assessment (an average of 3 weeks), and one-month follow-up ambulatory assessment (an average of 7 weeks)

    Stress events assessed on a binary scale (yes/no) in daily life four times per day for one week at three time points via Ecological Momentary Assessment (EMA), totaling up to 28 assessments at each time point. All 28 assessments at each of the three time points (pre-intervention ambulatory assessment, post-intervention ambulatory assessment, and one-month follow-up ambulatory assessment) were averaged in logistic MLM analyses. Outcomes are reported as mean percentage of surveys at each time point that stress events were endorsed, with higher percentages indicating more stress events.

  • Change in Daily Life Objective Stress: Daily Stress Events

    Daily stress events assessed in daily life each evening for one week at three time points via end-of day diary, totaling up to 7 assessments at each time point. All 7 assessments at each of the three time points (pre-intervention ambulatory assessment, post-intervention ambulatory assessment, and one-month follow-up ambulatory assessment) were averaged in logistic MLM analyses. Outcomes are reported as mean percentage of days at each time point that stress events were endorsed, with higher percentages indicating more stress events.

    change in stress assessed in daily life for 1 week at three timepoints: pre-intervention ambulatory assessment, post-intervention ambulatory assessment (an average of 3 weeks), and one-month follow-up ambulatory assessment (an average of 7 weeks)

  • Change in Daily Life Physiological Stress Reactivity

    Heart Rate (HR) measured continuously in daily life, with HR averaged in 30-minute windows around daily life stress reported via EMA up to four times per day for one week at three time points, totaling up to 28 windows at each time point. All (up to) 28 assessments at each of the three time points (pre-intervention ambulatory assessment, post-intervention ambulatory assessment, and one-month follow-up ambulatory assessment) were averaged in MLM analyses.

Mindfulness

Behavioral: Mindfulness

Coping

ACTIVE COMPARATOR

Coping intervention involving 14 foundational audio-guided lessons plus daily brief practice prompts. Lessons train techniques for 3 coping skills: reflection, reappraisal, and problem solving. Practice prompts delivered 3x daily build on the skills trained in each lesson.

Behavioral: Coping

Interventions

MindfulnessBEHAVIORAL

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.

Mindfulness
CopingBEHAVIORAL

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.
