In this pilot randomized controlled trial, conducted over one year, beginning in April 2021, 40 PEH were recruited from a larger sample of 100 PEH that were participating in a survey on COVID-19. Our outcomes were HRV and symptoms of anxiety, depression and PTSD.
Prior to the intervention, a Community Advisory Board (CAB) met to assess feasibility and acceptability of the HRV-BF program, which was presented in a theater-style approach. The CAB, composed of 6 PEH, and 3 healthcare providers, spoke quite favorably about the program, and provided exceptional feedback in terms of acceptability and feasibility in delivery logistics and cultural sensitivity. PEH shared the high levels of stress and anxiety they were experiencing; how helpful they perceived the program to be, the best timing for delivery, length of time for the intervention (under 60 minutes), and how to minimize attrition. Our study was approved by the Human Subjects Protection Committee at the University of California, Irvine and the University of California, Los Angeles.
