Mindfulness App Training for Cardiovascular Health

Study Summary

This study will investigate the feasibility and effects of a smartphone-based mindfulness training program vs. usual care in a sample of stressed midlife and older adults at risk for cardiovascular disease. 105 participants will be randomly assigned to complete a four-week mindfulness training intervention, which involves 28 audio-guided lessons and practice prompts delivered 3x daily, or to continue with their regular routines. Data will be collected at baseline, post-intervention, and three-month follow-up. The study will involve seven laboratory visits, which will include assessments and training on daily life monitoring and intervention procedures. Data assessing subjective and physiological stress reactivity in daily life will be collected for 3 days at pre-intervention, post-intervention, and 3-month follow-up. Passive sensor data will be continuously collected from participants' smartphones and wearable devices to develop models that predict daily life stress. Data will be used to evaluate feasibility of the intervention and assessments in a sample at risk for cardiovascular disease and to test effects of mindfulness training on subjective and physiological stress reactivity.

Primary Outcome

Task strain assessed as the proportion of hourly observations during each ambulatory monitoring period that are assigned ratings above the sample median on a 3-item Task Demand scale and below the sample median on a 2-item Decision Latitude scale, with higher scores indicating higher task strain
