testing a mindfulness/acceptance-based smartphone app for nurses impacted by the covid-19 pandemic

Conditions: Posttraumatic Stress Disorder

Summary: 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.
