Attention deficit hyperactivity disorder (ADHD) is the most common childhood neurodevelopmental disorder, with an estimated prevalence in adulthood of 2.5–3.4%. The Attention Deficit/Hyperactivity Disorder Rating Scale (ADHD-RS) is an 18-item self-administered scale that assesses attention deficit and hyperactivity/impulsivity symptoms of ADHD in adults. This study aims to validate the ADHD-RS in Spanish according to the diagnostic criteria established by the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5).
