Meta-analyses on mindfulness in the Spanish educational contextreported significant improvements along the same lines. The aim of this study was to determine whether a mindfulness-basedintervention for primary school students improved their sensitivity to anxiety.Method A total of 352 students (170 boys, 182 girls) aged 6 to 12 years participated in Spain. A quasi-experimental pre-test-post-test design was used, with experimental group (266 students) and control group (86 students). Anxiety sensitivitywas measured with the Anxiety Sensitivity Index for Children. The intervention followed a sequential learning order basedon the Mindfulness-Based Stress Reduction (MBSR) programme.Results A significant decrease in anxiety sensitivity was observed in the post-intervention measure. Additionally, compari-sons of pre-test and posttest scores in the control group revealed significant differences. In terms of effect size, the differencebetween pre- and post-intervention scores was close to medium (Cohen's d = 0.43).Conclusions The efficacy of the programme was confirmed, and it was shown that the mindfulness intervention was ben-eficial; in the experimental group, anxiety sensitivity decreased significantly compared to that in the control group afterparticipation in the programme.
