Effects of mindfulness-based interventions on psychological outcomes in college and university students during COVID-19 pandemics: A systematic review and meta-analysis.

OBJECTIVE: We synthesized the effects of mindfulness-based interventions (MBIs) on psychological outcomes in college and university students during the COVID-19 pandemic. METHOD: Ten electronic databases were searched from inception to December 2021. We reviewed studies with college and university students receiving MBIs with psychological outcomes. We only reviewed studies written in English. A random-effects model was used to compute the effect size. RESULTS: Overall, MBIs showed a significantly moderate improvement in anxiety (g = 0.612, 95% CI: 0.288-0.936, I2 = 77%); depression (g = 0.372, 95% CI: 0.032-0.713, I2 = 72%); and mindfulness (g = 0.392, 95% CI:0.102-0.695, I2 = 64%) compared with control groups, while these interventions had a small effect in reducing stress, but not a significant one (g = 0.295, 95% CI: -0.088 to 0.676, I2 = 77%) compared with control groups. CONCLUSION: MBIs significantly improved psychological outcomes among college and university students during the COVID-19 pandemic. Clinicians and health providers should consider using MBIs as alternative complementary treatment for improving and preventing anxiety and depression in college and university students during COVID-19. CLINICAL RELEVANCE: The use of MBIs for college and university students is an effective method to decrease anxiety, depressive symptoms, and increase mindfulness. MBIs would become a very useful means of alternative complementary treatment in mental health and clinical psychiatry.
