Pre-intervention (Time 1) measures were completed with children and parents at the time of enrollment, during the spring semester of students’ fourth grade year. Students participated in several sessions of the Coping Power intervention during the final months of fourth grade, and students and parents completed mid-intervention assessments (Time 2) during the summer after fourth grade. The Coping Power intervention continued during fifth grade, and students and parents completed post-intervention assessments (Time 3) in the summer following fifth grade. One-year follow-up assessments (Time 4) were completed after sixth grade. Most assessments took place in participants’ homes, but evaluations were also conducted in other locations chosen by the family (e.g., public library, research office) if requested. Children and parents were interviewed separately by research staff members who were blind to the children’s condition assignment. Parents received $50 for each assessment, and children received $10.
