Official title
Multisite Study of School-based Treatment Approaches for Adolescents With ADHD
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
We evaluated the extent to which receiving the school-based multi-component treatment of the Challenging Horizons Program (CHP) would lead to significant improvements in levels of symptoms of attention deficit hyperactivity disorder (ADHD) and social and academic functioning for high school aged adolescents diagnosed with ADHD. We intended to recruit 200 high school aged adolescents with a diagnosis of ADHD who would be randomly assigned to either CHP or a Community Care condition within each of 12 participating high schools. Outcome measures included parent, teacher and adolescent reports as well as observational data. Measures were collected at initial evaluations which preceded the one academic year of treatment, during the treatment period, and at six-months after treatment ended. Based on previous research with this treatment in middle and high schools, we anticipated meaningful gains for those in the treatment condition at post-treatment and larger gains on some variables at the 6-month follow-up evaluation.
