Which of the following is a diagnostic test for attention-deficit hyperactivity disorder (ADHD)?

A. Cesar's Assessment Scale. There is no widely recognized Cesar's Assessment Scale for diagnosing ADHD. B. Hamilton Assessment Scale. The Hamilton scales (HAM-A and HAM-D) are used to assess anxiety and depression, not ADHD. They measure emotional symptoms, somatic complaints, and cognitive impairments associated with mood disorders. C. Vanderbilt Assessment Scale. The Vanderbilt Assessment Scale is a validated tool used for ADHD diagnosis in children. It assesses inattention, hyperactivity, impulsivity, and associated behavioral problems based on parent and teacher reports. It also screens for common comorbidities such as oppositional defiant disorder (ODD) and anxiety disorders. D. Columbia Assessment Scale. The Columbia Suicide Severity Rating Scale (C-SSRS) is used to assess suicidal ideation and behavior, not ADHD. It is primarily applied in psychiatric evaluations and crisis intervention settings.
