Abstract: Our objective was to conduct the first randomized
controlled trial of the efficacy of a group
mindfulness program aimed at reducing and preventing
depression in an adolescent school-based population.
For each of 12 pairs of parallel classes with students
(age range 13–20) from five schools (N=408), one
class was randomly assigned to the mindfulness condition
and one class to the control condition. Students in
the mindfulness group completed depression assessments
(the Depression Anxiety Stress Scales) prior to
and immediately following the intervention and
6 months after the intervention. Control students completed
the questionnaire at the same times as those in
the mindfulness group. Hierarchical linear modeling
showed that the mindfulness intervention showed significantly
greater reductions (and greater clinically significant
change) in depression compared with the
control group at the 6-month follow-up. Cohen's d
was medium sized (>.30) for both the pre-to-post and
pre-to-follow-up effect for depressive symptoms in the
mindfulness condition. The findings suggest that school-based mindfulness programs can help to reduce
and prevent depression in adolescents.
