Attention deficit hyperactivity disorder (ADHD) is a childhood-onset neurodevelopmental disorder characterized by developmentally inappropriate and impairing inattention, motor hyperactivity, and impulsivity, with difficulties often continuing into adulthood (Thapar et al., 2016). ADHD is pervasive and developmentally inappropriate difficulties with attention, impulsivity, and hyperactivity (American Psychiatric Association, 2000). Symptoms cause significant impairments at home and in school and are associated with a number of behavioral difficulties such as aggression and noncompliance (Barkley, 2006). Research also suggests that children with ADHD are more likely than typically developing classmates to be rejected socially and to have greater difficulties with their peers (Hinshaw, 2002).
