Example Data Table

Profile Inattention Hyperactivity Impairment Total Percent Severity
Case A 10 8 4 22 24.44% Minimal
Case B 17 12 8 37 41.11% Mild
Case C 21 18 11 50 55.56% Moderate
Case D 24 22 14 60 66.67% Moderate
Case E 27 25 16 68 75.56% High

Formula Used

Inattention Score = Sum of 9 inattention ratings

Hyperactivity Score = Sum of 9 hyperactivity and impulsivity ratings

Impairment Score = Sum of 6 functional impact ratings

Total Score = Inattention + Hyperactivity + Impairment

Maximum Possible Score = 27 + 27 + 18 = 90

Severity Percentage = (Total Score ÷ 90) × 100

Internal score bands used here: 0–24.99% Minimal, 25–49.99% Mild, 50–74.99% Moderate, 75–100% High.

Frequently Asked Questions

1. Does this tool diagnose ADHD?

No. It is a structured symptom review tool. It helps summarize severity patterns and functional impact. Diagnosis requires a qualified clinician, history, and assessment across settings.

2. What does the percentage score represent?

The percentage shows how much of the maximum internal score was reached. It offers a simple severity snapshot for this page’s scoring model. It is not a medical diagnosis threshold.

3. Why are impairment questions included?

Symptoms matter, but real-world impact matters too. Adding impairment areas helps show whether attention and activity concerns affect work, school, home, or relationships.

4. Can adults use this tool?

Yes. The page includes child, adolescent, and adult age-group options. The output still remains a screening summary and should be interpreted with professional guidance.

5. What score range is considered high?

In this page’s internal model, 75% and above is labeled high. This band is for organizing results visually. It should never replace clinical judgment.

6. What export formats are available?

You can download the completed result as CSV and PDF. The exports include the summary values, profile details, and line-item responses.

7. Can teachers or parents complete it?

Yes. The respondent field allows self, parent, teacher, clinician, or other selection. This supports quick documentation of who completed the rating.

8. Why use a chart with the result?

The chart helps compare domains quickly. It highlights whether concerns are more prominent inattention, hyperactivity, or impairment, which makes reviews easier.
