The purpose of the study is to test the feasibility and acceptability of a mindfulness- and acceptance-based smartphone app (MABSA) intervention for frontline nurses emotionally and psychologically impacted by the COVID-19 pandemic. The study will use a randomized controlled trial design of two groups: an intervention group of about 30 participants with posttraumatic stress symptoms and a wait-list control group of about 30 participants. The duration of the MABSA intervention is 6 weeks. The following are the outcomes to be measured: resilience, PTSD, mindfulness, experiential avoidance, and rumination.
The objective of the proposed study is to evaluate the feasibility of the Mindfulness/Acceptance-Based Smartphone App (MABSA) intervention in a randomized controlled trial (RCT) environment and to obtain generalized information (i.e., initial efficacy, recruitment, retention, adherence, satisfaction, and usability of the refined intervention). The expected results will provide the foundation for a prospective, fully powered, larger-scale RCT study. The investigator previously developed the MABSA and pilot-tested it in a single-arm study among veterans, and the study will be testing the app among nurses who have been emotionally and psychologically impacted by the COVID-19 pandemic. Our central hypothesis is that the refined MABSA intervention would improve intervention satisfaction, app usability, and adherence and positively affect resilience, PTSD, mindfulness, experiential avoidance, and rumination. The specific aims of the proposed study are outlined below.
AIM 1: To refine the previously developed MABSA intervention. The 6-week smartphone-delivered program will involve (1) daily audio-guided meditations on various mindfulness and acceptance exercises constructed based on the principles of acceptance and commitment therapy; (2) weekly support and feedback through phone calls and/or texting the intervention facilitators; and (3) ecological momentary assessment (daily monitoring of PTSD and resilience) to monitor the progression of treatment response (i.e., the trajectory of resilience and PTSD recovery). The investigator will obtain qualitative feedback on program content and format through a pilot test of the prototype with a group of eligible nurses (N = 4). Upon revising the intervention based on participants' feedback, the investigator will develop the intervention protocol manual for the RCT.
AIM 2: To test the feasibility and acceptability of the refined MABSA intervention in a small-scale RCT for a prospective, fully powered, larger-scale RCT study. The small-scale RCT study will involve the following two groups of frontline nurses: (1) the MABSA intervention group (N = 30) and the wait-list control group (N = 30). Upon collecting the data on recruitment, retention, adherence, intervention satisfaction, and app usability, the study will determine the preliminary efficacy based on the following five outcomes: resilience, PTSD, mindfulness, experiential avoidance, and rumination. Qualitative feedback on the facilitators of and challenges to recruitment, retention, and adherence will be collected via exit interviews.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Mindfulness/Acceptance-Based Smartphone App (MABSA) Intervention Group | Experimental | The intervention is 6 weeks in duration. Participants will be asked to listen daily to at least one audio-guided mindfulness meditation embedded in the app. They will also be asked to watch a weekly video lesson on mindfulness and acceptance and will be asked to write a reflection about the video. They will also receive weekly emotional and technical support during the duration of the intervention. |
|
| Wait-List Control Group | No Intervention | The control group is a wait-list control group. Participants in the control group will be offered to use the app after 10 weeks of being in the study. The control group participants once they opted to use the app after 10 weeks will only have access to the app for 6 weeks. |
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|

| Mindfulness (Mindfulness Attention and Awareness Scale or also called MAAS) | Changes in mindfulness based on the Mindfulness Attention and Awareness Scale (MAAS). There are 15 items in the MAAS. The minimum value of MAAS is 15, and the maximum value is 90. Higher scores mean a better outcome (higher level of mindfulness). | The investigator will measure mindfulness (Mindfulness Attention and Awareness Scale, MAAS) at baseline, mid-intervention (Week 3), post-intervention (Week 6), and at one-month follow-up |
| Experiential Avoidance (Acceptance and Action Questionnaire or also called AAQ) | Changes in experiential avoidance based on the Acceptance and Action Questionnaire (AAQ). There are 7 items in the AAQ. The minimum value of the AAQ is 7, and the maximum value is 49. Higher scores mean a worse outcome (higher level of experiential avoidance or the unwillingness to be present with difficult emotions and thoughts). |
| Measure | Description | Time Frame |
|---|---|---|
| Posttraumatic Stress Disorder Recovery (Abbreviated Version of the Posttraumatic Stress Disorder Checklist or also called PCL-8) | Daily measures of posttraumatic stress disorder (PTSD) using the abbreviated PTSD Checklist for DSM-5 (PCL-8). The PCL-8 is a shortened version of the PCL-20. There are 8 items in the PCL-8. The minimum value is 0, and the maximum value is 32. Higher scores mean a worse outcome (greater severity of Posttraumatic Stress Disorder symptoms). |
| Measure | Description | Time Frame |
|---|---|---|
| Intervention Satisfaction (Intervention Satisfaction Survey or also called ISS). | The Intervention Satisfaction Survey (ISS) will be used to determine the degree of acceptability of the intervention (e.g., overall satisfaction, perceived helpfulness, comprehension, intentions to use, and perceived fit). There are 8 items in the ISS. The minimum value for the ISS is 8, and the maximum value is 48. Higher scores mean a better outcomes (indicating higher level of satisfaction with the app). |
