University of Cambridge researchers conducted a study on the effectiveness of mindfulness-based programs (MBPs) in reducing psychological distress. They analyzed data from 2,371 adults who participated in MBP trials and found that attending in-person mindfulness courses led by teachers in a group setting resulted in a small to moderate reduction in psychological distress. Approximately 13% more participants experienced a benefit compared to those who did not attend MBPs. The study confirmed that in-person mindfulness courses offered in the community can be beneficial for the average person in terms of improving mental health. The researchers suggested that workplaces and educational institutions should consider implementing similar teacher-led programs to prevent mental health problems in their communities. They also highlighted the lack of evidence supporting the effectiveness of mindfulness apps compared to in-person courses. Further research will investigate the effectiveness of smartphone apps and individual mindfulness practice.
