SMILE: Clinical Trial to Evaluate Mindfulness as Intervention for Racial and Ethnic Populations During COVID-19

The goal of this clinical trial is to evaluate the SMILE app, a Digital Health Platform (DHP), that will deliver a mindfulness intervention, designed to mitigate COVID-19 related stress. Additionally, the SMILE app will remotely collect self-reported psychological and physiological metrics of mental health and autonomic regulation. Study participants are adults who self-identify as African American, Black and/or Latino, and who have clinically significant levels of anxiety.

The study aims are:

* Aim 1: Establish the effectiveness and durability of an 8-week Mindfulness DHP intervention. The investigators will focus on two constructs important to mental health and hypothesize that: A) Anxiety, self-report stress and quality-of-life measures will significantly improve when comparing: A.1) Pre-to-post intervention, and; A.2) Control vs. intervention groups over 8 weeks and at 1-month follow-up. B) Arousal, autonomic indices of HRV (reflecting parasympathetic activation) will significantly improve, when comparing: B.1) Pre-to-post intervention, and; B.2) Control vs. intervention groups over 8 weeks and at 1-month follow-up.
* Aim 2: Establish the sustainability of two Mindfulness DHP interventions utilizing retention, usage (frequency), and participant satisfaction.
* Aim 3: Examine associations between COVID-19 related stress, mental health outcomes, and HRV. Examine the extent to which COVID-19 related stress and mental health symptoms are linked to HRV at baseline and how that relationship changes over time.

Participants will be assigned to 1 of 3 arms of the study: MTIA intervention, MAPP intervention, or wait-list control. All participants will be mailed a device with the SMILE app installed, and the equipment for recording cardiac data in the home. All participants will complete the baseline psychometrics measures and physiological stress test using the instructions provided on the SMILE app. Those assigned to the MTIA or MAPP intervention groups will then participate in their assigned intervention over the subsequent 8 weeks. During these 8 weeks, psychometric and physiological data will be completed biweekly for all participants. 3 months following the initial baseline, all participants will complete a final psychometric/physiological evaluation.

All data collection will occur remotely and intervention sessions will be virtual (i.e., in participants' homes). Participants will be provided with a tablet loaded with the SMILE app and a heart rate monitor and will view, or participate in, a virtual introductory tutorial on the use of the equipment. All psychological and physiological data will be collected via the SMILE app. Participants will be assigned to 1 of 3 groups (MTIA, MAPP, WLC), and all participants will complete each scheduled assessment, regardless of group assignment.

1. Baseline assessment (week 0). Participants will complete demographic and psychological questionnaires followed by a HRV assessment protocol, which consists of asking participants to attach the heart rate monitor and follow the instructions/model on the app to complete a cognitive stress test and an orthostatic test.

   In addition to the demographic questionnaire, the psychological measures included in the baseline assessment are: GAD-7, COVID Stress Scale (COVID-SS), Connor-Davidson Resilience Scale (CD RISC), Mental Health Quality of Life (MHQoL), Coping Orientation to Problems Experienced Inventory (Brief COPE), Perceived Stress Scale (PSS), Posttraumatic Growth Inventory (PTGI), sleep disturbance (Adult Patient-Reported Outcomes Measurement Information System (PROMIS) Short Form), PTSD Checklist, Center for Epidemiologic Studies Depression Scale (CES-D), Cognitive and Affective Mindfulness Scale-Revised (CAMS-R), and physical health (Short Form Health Survey, SF-12).
2. Intervention (weeks 1-8). Participants assigned to the MTIA and MAPP groups will participate in the 8 week intervention. Both intervention programs are mindful meditative practices, designed to cultivate regulation of attention to present moment awareness, as well as develop mindfulness and awareness skills to improve coping and reduce stress, thereby lowering anxiety and increasing well-being.

   The MTIA will be instructor led, internet-delivered (via Zoom), interactive, group-based mindfulness training intervention that will incorporate the training for approximately 9 persons in a group format, with outside-of session assignments. The MindfulnessAPP (MAPP) is a self-administered, internet-delivered intervention developed by the SMILE study team.

   Biweekly during weeks 1-6, participants in all groups will be asked to complete assessments which include psychological questionnaires (GAD-7, COVID-SS, CD RISC, CAMS-R) and the same HRV assessment protocol as the baseline. Participants in both mindfulness groups will be asked to provide documentation of mindfulness practice.
3. 8 week and follow-up assessment at week 12: participants in all groups will be asked to complete assessments which include psychological questionnaires (GAD-7, COVID-SS, CD RISC, MHQoL, COPE, PSS, PTGI, PROMIS, PTSD Checklist, CES-D, CAMS-R, and SF-12) and the same HRV assessment protocol as the baseline.
