Remote Mindfulness Training for Health Following Early Life Adversity: A Randomized Controlled Feasibility Trial

Early life adversity confers lifelong health risk, and mindfulness-based interventions (MBIs) show promise for mitigating risk. This trial evaluated feasibility and acceptability of remote mindfulness and coping interventions among emerging adults who recalled childhood trauma with the goal to inform an efficacy trial examining stress-related health outcomes. Eighty-one healthy adults (ages 18-29) who recalled physical, emotional, or sexual abuse during childhood were enrolled. Participants were randomly assigned to 2-week mindfulness or coping comparison interventions and completed lab-based and ambulatory assessments at preintervention, postintervention, and one-month follow-up. Primary outcomes included measures of feasibility and acceptability. Global psychosocial outcomes were secondary. Enrollment and retention targets were reached; of 891 people recruited, 81 were eligible and enrolled, and 88% completed the trial. The intervention programs met benchmarks for feasibility, acceptability, and safe implementation. Participants completed 95% of intervention lessons and 59% of daily life practice prompts, and 93% reported positive treatment expectancies. Three mindfulness participants (8%) showed substantial increases in mental health symptoms. No serious adverse events were reported, but 53% of participants had challenging emotional experiences during the training. The assessment protocol was feasible, with 87% of ambulatory assessments and 99% of blood samples collected. There were no group differences on feasibility/acceptability outcomes. Participants in both groups showed medium-sized improvements on global mental health and mindfulness measures. Two-week remote mindfulness and control interventions were feasible and acceptable among adults exposed to childhood trauma. Further work is warranted to evaluate whether MBIs can offset health risk.
