Example Data Table

These example rows show how summary outputs may look for hypothetical cases. They are illustrative and should not be treated as norms.

Example Case Inattentive Positives Hyperactive Positives Performance Problems Total Symptom Score Summary Output
Case A 7 4 2 30 Predominantly inattentive screen positive
Case B 3 7 1 29 Predominantly hyperactive/impulsive screen positive
Case C 7 7 3 42 Combined screen positive

Formula Used

Total Symptom Score = sum of items 1 through 18, each scored from 0 to 3. The possible total range is 0 to 54.

Inattentive Positive Count = number of items 1 through 9 scored 2 or 3.

Hyperactive or Impulsive Positive Count = number of items 10 through 18 scored 2 or 3.

Average Performance Score = sum of items 48 through 55 divided by 8. Items scored 4 or 5 count as performance problems.

ADHD Screen Logic = at least 6 inattentive positives or at least 6 hyperactive positives, plus at least 1 performance problem.

Related Flags = ODD requires 4 of 8 positives, conduct requires 3 of 14 positives, and anxiety or depression requires 3 of 7 positives, each with impairment.

Custom Severity Band is a page-generated convenience label based on the total symptom score only. It helps quick review and does not replace clinical judgment.

How to Use This Calculator

  4. Review symptom counts together with the performance problem count and the presentation summary.
  5. Use the CSV or PDF buttons to save the calculated summary for later review.

FAQs

1) Does a high result confirm ADHD?

No. A high result means many symptoms and impairment concerns were endorsed by a parent. Diagnosis requires clinical review, history, and information from multiple settings.

2) Why are performance items included?

Symptoms alone do not show the full picture. Performance ratings help show whether daily functioning is affected in school, relationships, or organized activities.

3) What does “screen positive” mean?

It means the entered responses crossed the calculator’s screening threshold. It does not prove a diagnosis. It signals that follow-up review may be appropriate.

4) Can this be used for progress tracking?

Yes. Repeating the same structured rating process over time can help compare change. Interpretation still works best when combined with professional review.

5) Why are mood and conduct items present?

Attention problems can overlap with emotional or behavioral difficulties. These extra sections help organize observations that may need separate evaluation or support.

6) Is the severity band official?

No. The severity band in this page is a convenience label. The more important outputs are the symptom counts, impairment, and clinician-reviewed context.

7) Can teachers use this same page?

This build is arranged for parent input. Teacher ratings are also valuable, but they should usually be gathered separately and compared with home observations.

8) What should happen after getting the result?

Save the summary, collect concrete examples, and discuss them with a pediatrician, psychologist, counselor, or school support team for next-step guidance.
