Example Data Table

This sample shows how different response patterns produce different domain totals and overall score bands.

Profile	Q1	Q2	Q3	Q4	Q5	Q6	Q7	Q8	Q9	Q10	Q11	Q12	Q13	Q14	Q15	Q16	Q17	Q18	Total	Band
Case A	6	5	4	3	2	4	3	4	2	3	2	2	1	2	2	3	1	2	55	Moderate
Case B	2	1	2	1	1	2	1	2	1	1	0	1	0	1	1	1	0	1	18	Minimal
Case C	4	4	3	4	4	3	4	4	3	4	3	3	3	4	3	4	3	3	66	High

Formula Used

Total Score = Sum of all 18 item scores

Inattention Score = Sum of Q1 to Q9

Hyperactivity / Impulsivity Score = Sum of Q10 to Q18

Domain Percent = (Domain Score ÷ 36) × 100

Total Percent = (Total Score ÷ 72) × 100

High Frequency Count = Number of items scored 3 or 4

Interpretation Bands

0 to 18: Minimal
19 to 36: Mild
37 to 54: Moderate
55 to 72: High

These ranges help organize self-reported symptom frequency. They are not diagnostic thresholds and should not replace clinical assessment, history review, or professional judgment.

Important Notes

This calculator is intended for reflection and structured symptom tracking. It does not diagnose ADHD, confirm a disorder, or replace professional mental health care.

A full evaluation usually considers symptom history, daily impairment, developmental context, other possible causes, and information from qualified professionals.

FAQs

1. What does this calculator measure?

It measures self-reported frequency of attention, restlessness, and impulsive behavior patterns across eighteen symptom prompts. It summarizes domain totals and an overall score band.

2. Is this calculator a diagnosis tool?

No. It is a self-assessment score calculator only. Diagnosis requires a qualified clinician, clinical history, functional impact review, and broader mental health evaluation.

3. What does a higher score mean?

A higher score means you selected more frequent symptom responses. It suggests stronger ADHD-like patterns in this questionnaire, but not a confirmed condition.

4. Why are there two domain scores?

The calculator separates inattention from hyperactivity and impulsivity. This helps you see which symptom group contributes more to your overall result.

5. What is the high frequency count?

It counts items marked Often or Very Often. This gives a quick view of how many symptoms were reported at a higher frequency level.

6. Can I use this for repeated tracking?

Yes. Repeating the assessment over time can help you compare score patterns, identify triggers, and discuss changes with a professional.

7. Should I share these results with a clinician?

Yes, especially when symptoms interfere with routine functioning. The score summary and notes may support a more structured discussion during an appointment.

8. Can stress or sleep affect scores?

Yes. Stress, anxiety, low sleep, burnout, substance use, and other health issues can affect attention, restlessness, and impulsive behavior patterns.
