Study Details
Setting
The study took place in 2 preschools—1 each in the cities of Houston, Texas and Washington, DC—over a 6-week period. Intervention conditions were administered in small groups.
Study sample
The 218 children who were randomly assigned ranged in age from 47-63 months with a mean age of 57 months (between the ages of 3 and 5 years old) and were 54 percent female. The authors do not provide any other demographic information for the randomized or analytic samples. Houston served children who were primarily Hispanic White, 55 percent White, 9 percent African American, 32 percent more than one race, 3 percent Native American, 97.4 percent Hispanic, and 68 percent Primary language English. Schools in Washington, DC served children who were 100 percent African American.
Intervention Group
The Mindfulness + Reflection intervention was provided to children during 30 small-group (8-12 children) sessions. The sessions were 24 minutes daily for 6 weeks. Children participated in a variety of brief mindfulness and relaxation practices adapted for children. Children also played three games designed to challenge executive functioning: head/toes/knees/shoulders, Bear/Dragon/Simon Says, and Mother May I? The mindfulness exercises, typically involving small props, were repeated across sessions. The games each had different amounts of executive function challenge, which allowed instructors to moderately challenge children’s skills. Instructors were also given other teaching techniques for adjusting the challenge level. During the games, instructors encouraged children to notice and discuss their thoughts, emotions, and behavioral tendencies.
Comparison Group
Children in the comparison condition received the usual instruction in their regular classrooms. In Houston, this involved regular classroom activities at the Houston school; in Washington, this involved the Second Step social-emotional learning intervention.
Support for implementation
The teachers recruited to deliver the 2 study interventions received a full day of training at the University of Minnesota. Two teachers were trained to administer activities in the 14-lesson mindfulness curriculum and three executive function (EF) - challenging games presented with reflection protocols.
An indicator of the effect of the intervention, the improvement index can be interpreted as the expected change in percentile rank for an average comparison group student if that student had received the intervention.
For more, please see the WWC Glossary entry for improvement index.
