The calculator in question is the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, 5th Edition) diagnostic criteria for ADHD (Attention-Deficit/Hyperactivity Disorder) in children, specifically the hyperactive-impulsive subtype. This calculator is used by clinicians to diagnose ADHD in children and adolescents, typically between the ages of 6 and 17. 

The DSM-5 criteria for ADHD, hyperactive-impulsive subtype, requires the presence of six or more specific symptoms of hyperactivity-impulsivity for at least six months to an extent that is inconsistent with the developmental level and that negatively impacts directly on social and academic/occupational activities. 

The clinical utility of this calculator is to provide a standardized, evidence-based tool for diagnosing ADHD, hyperactive-impulsive subtype, in children and adolescents. This can guide appropriate treatment strategies, including behavioral therapy and medication management. 

Exclusion criteria for the use of this calculator include symptoms that are better explained by another mental disorder, symptoms that are not due to the direct physiological effects of a substance (e.g., a drug of abuse, medication) or another medical condition (e.g., hyperthyroidism), and symptoms that do not cause clinically significant distress or impairment in social, academic,
