Multisite Study of High School-based Treatment for Adolescents With ADHD
NCT04480346 · View on ClinicalTrials.gov ↗
Study Summary
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.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT04480346
The ClinicalTrials.gov registry entry for NCT04480346 describes a study currently listed as completed. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 186 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Ohio University, which has 19 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Attention Deficit Hyperactivity Disorder appearing as the primary indexed condition, and to 1 intervention — of which Challenging Horizons Program is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT04480346 reports 2 study locations spanning 2 distinct geographic areas — top geographies include Ohio, Pennsylvania. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
