Primary outcome measure(s)
Standardized QbMobile Scores of the four parameters: Attention, Impulsivity, Activity, and Movement Patterns. — 10-minute testing period QbMobile generates standardized scores (SD-scores) for attention, impulsivity, activity, and movement patterns using age and sex at birth adjusted norms. These scores provide objective data collected during the 10-minute test session and are automatically included in a standardized report generated immediately upon test completion. This supports evaluation of test validity for ADHD-related symptom measurement.
