Mindfulness-Based Versus Story Reading Intervention in Public Elementary Schools: Effects on Executive Functions and Emotional Health

INTRODUCTION: In this study we compared the effects of a mindfulness-based intervention (MBI) with a story reading intervention (SI) on the executive functions and psychological profile of children in two different public schools in São Paulo, Brazil. METHODS: In this controlled clinical trial, 207 children aged 8 to 9 years old responded to the Five-Digit Test (FDT), stress levels, depression, anxiety, positive and negative affect, at baseline (T0) and 8 weeks later (T1). From T0 to T1, school 1 participated in MBI classes and school 2 in IS classes. RESULTS: In school 1 (MBI), children improved their scores on all tests except reading (errors) and counting (errors) compared with school 2. No differences were observed between groups in terms of emotional health. CONCLUSION: It is feasible to implement MBI or SI in Brazilian public schools. Students in the MBI group presented broader effects in executive functions, while students in the SI group showed a trend toward reduced negative affect and depression symptoms.
