研究概览
简要总结
The aim of the Everyday Moments of Mindfulness (EMMI) study is to test whether brief mindfulness-based practices will improve daily psychological stress responses in women (age 30-60) who report a history of early life adversity. Following a baseline visit (remotely or in person), participants complete daily surveys and audio-guided mindfulness-based practices in everyday life via the study app. Specifically, participants receive app-notifications three times/day (morning, afternoon, evening) to complete daily surveys of current stressors and psychological states. At each notification, each participant is then randomly assigned to either receive a mindfulness-based intervention or not (max of 3 interventions/day). Thus, participants are randomized many times over the course of this 30-day study. At the end of the study, participants complete a follow-up visit (remotely or in person).
详细描述
The aim of the present study is to test whether brief app-based mindfulness and compassion practices will improve daily psychological stress responses in a sample of adult women (age 30-60) who report a history of early life adversity. The study will incorporate surveys and mindfulness-based intervention practices into everyday life using mobile technology (study app). Participants receive app-notifications three times/day (morning, afternoon, evening) to complete Ecological Momentary Assessments (EMAs) of current psychological stress states (pre-EMA; e.g., stress appraisals, affect, perseverative cognitions, self-criticism, social connection). At each notification, each participant is then randomized to either receive a mindfulness-based intervention (described in detail below) or no intervention. Thus, each participant is randomized many times over this 30-day study (Micro-Randomized Trial, MRT). Psychological stress states are again measured approximately 15 min post-randomization (post-EMA; e.g., stress appraisals, affect, perseverative cognitions, self-criticism, social connection) to assess a treatment effect by comparing psychological stress responses after a mindfulness-based intervention vs. no intervention. The MRT will continue for 30 days. All study participants will be asked to fill out questionnaires at baseline and post-intervention (after 30 days). Weekly measures of depressive symptoms are also obtained. A trained research assistant will monitor participant adherence and address potential difficulties.
Mindfulness-based intervention: The intervention consists of mindfulness and compassion-based practices. For example, practices focus on the breath/body (e.g., 3 minute breathing space; compassionate body scan; five senses mediation), on increasing participants' inner resources (e.g., imaging a safe person or safe place), on reducing negative affect (e.g., self-compassionate and acceptance-based practices), or on increasing positive emotions (e.g., gratitude practice; metta practices). All interventions are brief (≤5 minutes) and audio-guided.

盲法说明
Since the study uses a MRT design (each participant is randomized multiple times), the investigator and outcomes assessor do not know at what time points participants are assigned to an intervention or not over the course of this 30-day study.

结局指标
主要结局
Change in Negative Affect, as Measured by Ecological Momentary Assessment (EMA)
时间窗: From pre-EMA (immediately prior to intervention randomization) to post-EMA, approximately 15 minutes post-randomization, over a period of 30 days.
Negative affect was measured by computing a total mean score of "I feel sad, downhearted, unhappy" and "I feel angry, irritated, frustrated." The total mean score ranges from 1 to 7, with higher scores indicating greater negative affect. Negative affect was measured at notification time points 3 times/day over a 30-day period. At each notification time point, participants completed EMAs of negative affect immediately prior to intervention randomization (pre-EMA) and approximately 15 minutes post randomization (post-EMA). Change in negative affect was calculated as post-EMA minus pre-EMA.
Change in Stressor Demands, as Measured by Ecological Momentary Assessment (EMA)
时间窗: From pre-EMA (immediately prior to intervention randomization) to post-EMA, approximately 15 minutes post-randomization, over a period of 30 days.
Stressor demands were measured by computing a total mean score of "I feel stressed, anxious, overwhelmed" and "I feel strained, upset, overburdened." The total mean score ranges from 1 to 7, with higher scores indicating greater stressor demands. Stressor demands were assessed at notification time points 3 times/day over a 30-day period. At each notification time point, participants completed EMAs of stressor demands immediately prior to intervention randomization (pre-EMA) and approximately 15 minutes post randomization (post-EMA). Change in stressor demands was calculated as post-EMA minus pre-EMA.
