Research Description

Dr. Sibley’s research involves finding ways to export effective ADHD treatments into real world settings such as schools and community clinics. Her team is currently evaluating STRIPES, which teaches academically successful high school students to deliver school-based interventions to peers with ADHD. She also is currently partnering with community mental health agencies to modify STAND for community settings and local schools to create a summer orientation to high school for students at risk for a shaky transition to ninth grade.
