What this trial studies
This project aims to evaluate the effectiveness of OROS-methylphenidate compared to a placebo in treating ADHD symptoms among incarcerated individuals over a three-month period. The study will utilize a randomized controlled trial design, assessing not only the core symptoms of ADHD but also the impact on behavior, recidivism rates, and medication adherence both during and after incarceration. Participants will receive cognitive-behavioral psycho-education while detained and have access to cognitive-behavioral therapy post-release. The study seeks to provide comprehensive evidence on the benefits of ADHD treatment in a prison setting.
Why it matters
Potential benefit: If successful, this treatment could significantly reduce ADHD symptoms and associated negative outcomes, including recidivism, in incarcerated individuals.
How similar studies have gone: While ADHD treatment in prison settings is relatively novel, similar studies have shown promising results in improving outcomes for individuals with ADHD in various contexts.
