Examine the Effects of Mindfulness in Woman With a History of Child Adversity

The pilot Randomized Controlled Trial (RCT) randomly assigns midlife women (age 30-50) with a history of early life adversity to either a Mindful Activity group or a Mindful Awareness group to primarily test acceptability, feasibility, and adherence. Randomization will occur by chance at the end of the baseline visit.

Participants randomized to the Mindful Activity group will receive 8 weeks of ecological momentary assessment and intervention sessions via the study app. Mindfulness-based interventions consist 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 audio-guided and approximately 5-10 minutes. Participants complete two mindfulness interventions/day (one in the morning; one in the evening). After completing a mindfulness-based intervention, participants will complete ecological momentary assessments of their current psychological stress states (e.g., stress appraisals, affect, perseverative cognitions, self-criticism, social connection) via the study app.

Participants randomized to the Mindful Awareness group are instructed to be mindful (pay attention) to their current thoughts and feelings and complete ecological momentary assessments of their current psychological stress states (e.g., stress appraisals, affect, perseverative cognitions, self-criticism, social connection) twice/day (morning and evening) for 8 weeks via the study app.

A trained research assistant will monitor participant adherence and address potential difficulties. All participants will complete assessments at baseline (pre-intervention) and post-intervention (after the 8-week intervention). Weekly measures of depressive symptoms are also obtained. The investigators plan to consent about 100 participants with the goal of having 70 eligible participants enrolled in the study (about 35 in each group).
