Mind-body medicine (MBM) is an evidence-based intervention associated with trauma and stressful events. The MBM intervention alleviates symptoms of work-related stress and builds resilience by utilizing self-care techniques facilitated in small group settings. Healthcare leaders who experienced traumatic stress through the COVID-19 pandemic may benefit from interventions aimed at their needs. We evaluated the effects of a peer support MBM intervention on perceived stress, resilience, well-being, and empathy for nurse leaders and compassionate care leaders. A pre-post intervention was conducted via 7 virtual and 2 on-site groups, recruiting from a large multihospital health system in the United States. Participants engaged in an 8-week program facilitated by a certified faculty group leader from The Center for Mind-Body Medicine and engaged in resilience skills building activities along with facilitated sharing. Validated instruments were used to measure outcomes at pre, post, 1 month, and 6 month follow-up intervals. Surveys included open-ended questions for qualitative feedback related to facilitators, barriers, and group experiences. Seventy-three leaders completed the MBM program, and 22 completed the four research surveys; all qualitative responses were included for feedback. Perceived stress decreased after the intervention (p < .008) and was maintained for 6 months post intervention (p < .005). Resilience increased after the intervention (p < .034) and for 1 month (p < .049) but decreased after 6 months. Qualitative responses showed that time and workload factors were the most significant barrier to participation, while the benefits included protected time with peers, learning well-being skills, and having a safe place to process emotions. Healthcare leaders face unique challenges, including workplace trauma and crises. Interventions that support their stress response, resilience, and overall well-being should take into consideration the nature of their work, the balance of time demands, and the need for peer support to overcome barriers to sustainable interventions.
