An ADHD self-test is a preliminary assessment that measures symptom frequency on a scale, typically indicating low (0-17), moderate (18-24), or high (25+) likelihood of ADHD traits, serving as a guide for seeking professional advice.

This tool incorporates DSM-5 criteria to provide reliable insights, breaking down results by category with explanations of common signs like forgetfulness or restlessness. It highlights that results are not diagnostic but educational, encouraging consultation with healthcare providers for accurate evaluation.

Inattention0–10Higher score = more inattentive traits
Hyperactivity0–10Higher score = more hyperactive traits
Impulsivity0–10Higher score = more impulsive tendencies
Organization Skills0–10Higher score = more difficulty in organization

Risk Level Categorization:

Total Score = Sum of all domain scores
