Pilot study of an online brief mindfulness-based intervention to improve the well-being of managers and reduce their stress at work.

. The COVID-19 pandemic, remote work and new technologies have heightened workplace pressures. Effective response and essential organizational changes require business leaders to be more adaptable, with managers' presence playing a pivotal role in successful implementation. The study assesses a brief mindfulness-based emotional regulation for managers (MBERM) intervention, to reduce workplace stress and enhance managerial well-being. . An 8-week non-randomized controlled trial was conducted with a waiting list control group and an intervention group. Pre-post differences were measured by Student's test or Wilcoxon test, and effect size calculated using the Hedge's formula. The sample included 23 managers (17 men and six women) with average age 50 years. The study assessed anxiety and depressive symptoms, psychological flexibility, perceived self-efficacy, general work-related well-being, perceived stress and mindfulness. . Statistically significant changes were observed in the intervention group in depression, anxiety, work-related acceptance and action, general self-efficacy, exhaustion, alienation, stress and non-reactivity. The control group showed no statistically significant changes in any of the variables. . The MBERM intervention could improve the emotional and work-related well-being of managers and reduce stress levels and burnout. Further study of this intervention is needed to promote adherence and ensure a long-term improvement.
