Resumen
Organizations today are implementing psychological interventions to promote the job performance and wellbeing of their employees. Mindfulness-based interventions (MBIs) can contribute to providing workers with competencies and skills and develop their strengths. MBIs are therefore becoming more and more present in the workplace, sometimes using online intervention programs, which offer a promising direction in prevention and intervention for health. The objective of this study is to analyze the efficacy of MBIs on psychological variables in the workplace. For this purpose, a search for scientific articles published from 2009 to 2019 was made in the Psicodoc, PsycINFO, and Web of Science databases, where a total of 468 articles were found. After filtering with preestablished inclusion criteria, 24 studies were included in the systematic review and meta-analysis. The results of the meta-analysis suggest that intervention in mindfulness positively influences psychological variables related to employee health and wellbeing. However, it is recommended to continue performing new studies to confirm this finding.
