Mindfulness Takes Practice

The purpose of the study is to optimize the delivery of mHealth tools to support the formation of persistent mindfulness meditation routines. Aim 1: Identify the efficacy of the anchoring strategy on the persistence of daily meditation practice. H1: Persistence (measured through repeated observations of panel regression models of the daily likelihood of mindfulness mediation over the 16-week follow-up period) will be greater among AG as compared to CG. Aim 2: Determine participant phenotypes that are (a) associated with successfully anchoring daily meditation or (b) likely to need additional supports. Potential moderators of the anchoring strategy's success include participants' daily schedule, type of work, household composition, motivation, time and risk preferences, and prior exposure to mindfulness, which will be analyzed in the panel regression model framework above. Aim 3: Determine the optimal type, timing, and sequence of push notifications for encouraging daily mindfulness meditation within and across study groups. The efficacy of each push notification type (tracking sessions completed, reminders, mood symptom tracking, and group-specific goal reminders), timing, and dynamics on the anchoring of daily meditation will inform a subsequent, just-in-time adaptive intervention (JITAI). Impact: This study will inform an optimal JITAI R01 proposal that will personalize the type and temporal dynamics of app-based daily supports for successfully routinizing daily meditation, and determine its effects on mental health, specifically PTSD. Lifetime prevalence of PTSD is 7% in adults and meditation is known to reduce PTSD. If effective
