Mindfulness-Based Interventions (MBIs) have gained traction in various healthcare settings, particularly for stress reduction among healthcare professionals. This meta-analysis aimed to evaluate the effectiveness of MBIs on reducing stress and depression in obstetrical nurses.
A comprehensive literature search was done across multiple databases, including Cochrane Library, PsycINFO/PsycNet, PubMed/MEDLINE, Web of Science, and Google Scholar. The risk of bias for each included study was assessed using the Cochrane Risk of Bias Tool. Subgroup analyses were done according to intervention time (less than 8 weeks, 8 weeks, more than 8 weeks) and population. Meta-analysis was done using random-effects models. Effect sizes were calculated using standardized mean differences (SMD). Heterogeneity was assessed using the I 2 statistic.
The sample size in 55 studies was 4612 nurses and midwives (2904 in the intervention group and 1708 in the control group). The meta-analysis showed a significant overall effect of MBIs on reducing stress levels (SMD = −0.71; 95% CI [−0.97, −0.44]; p < 0.001), and depression (SMD = −0.74; 95% CI [−1.35, −0.13]; p < 0.001) among midwives and nurses. Subgroup analysis showed that the effects of intervention duration on reducing stress (X 2 = 3.01, p = 0.220) was not significant, but its effect on depression (X 2 = 61.46, p = 0.000) was significant.
Healthcare organizations should integrate structured MBIs into staff wellness initiatives to promote mental well-being. Nursing education programs can include mindfulness components to strengthen coping skills. Future work should also examine combined mindfulness–CBT programs (e.g., MINDBODYSTRONG) and address organizational factors contributing to burnout for a more comprehensive approach.
