First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a program called 'Thoughts and Health' designed to prevent depression in adolescents. The program is delivered in 12 sessions in a school setting. Researchers will see if it helps students' mental health and their ability to finish junior high with passing grades. The study involves 40 eighth graders who are not currently depressed.
