Students were randomized to an intervention group of 20 students receiving small-group yoga/mindfulness activities for 8 weeks between October 2016 and February 2017, and a control group of 32 students receiving care as usual. The Brief Multidimensional Students’ Life Satisfaction Scale-Peabody Treatment Progress Battery and the Pediatric Quality of Life Inventory (PedsQL) served as outcomes. Teachers were invited to participate in two professional development sessions about introducing yoga and mindfulness into the classroom, and completed a survey following each of the sessions.Results: In generalized estimating equation models adjusted for time, the yoga-based intervention was associated with a 14.17 unit increase in student emotional PedsQL (p-value 0.001) and a 7.43 unit increase in psychosocial PedsQL (p-value 0.01). Results were not attenuated by adjustment. Teachers and staff reported using yoga more frequently in the classroom following the second of two professional development sessions (p-value <0.05). Perceived barriers to introducing yoga to the classroom were similar at two data collection time points, while perceived benefits remained high.Conclusion: The intervention was associated with a significant improvement in emotional and psychosocial quality of life in the intervention group when compared to the control group, suggesting that yoga/mindfulness interventions may improve symptoms of anxiety among students. Yoga/mindfulness activities may facilitate stress management among elementary school students and may be added as a complement to social and emotional learning activities.
