What this screening form captures

This calculator offers a 6‑item screener or an 18‑item checklist for adults. Items cover two domains: Inattention (9 items) and Hyperactivity/Impulsivity (9 items). Responses use a frequency scale: Never=0, Rarely=1, Sometimes=2, Often=3, Very Often=4. Rate symptoms over the past 6 months. Totals span 0–24 and 0–72.

How the Part A shaded count works

The quick screener uses the first 6 items as Part A. Each item has an endorsement threshold that flags higher‑frequency responses. The shaded count is the number of Part A items meeting that threshold (0–6). Thresholds vary by item. A common screen is 4+ shaded responses, suggesting follow‑up evaluation in many clinical settings.

Understanding Likert totals and bands

The calculator also adds a Likert total for Part A (0–24). Higher totals reflect more frequent symptoms across the 6 items. A cutpoint used in scoring updates is 14+. The tool groups totals into four bands: 0–9, 10–13, 14–17, and 18–24, summarizing intensity quickly. Bands help track change across repeat checks.

Using the full checklist for symptom detail

With the 18‑item checklist, you get a total Likert score from 0–72 plus domain totals from 0–36 for each domain. The calculator counts endorsed symptoms by domain (0–9 each) using item‑specific thresholds. This separates attention items (1–9) from activity/impulsivity items (10–18). Part B can guide follow‑up questions.

Placing results in population context

Population estimates vary by method, but a global synthesis reported persistent adult ADHD around 2.58% and symptomatic adult ADHD around 6.76%. Screening results are not prevalence, yet these figures show why many adults report attention and regulation difficulties. Consider other contributors too: sleep, stress, anxiety, depression, or substance use. A clinician can differentiate overlapping causes and impacts.

Turning a screen into next steps

Use the chart and summary to support a focused clinician visit. Bring your exported CSV or PDF, note examples of functional impact at work, school, or home, and describe when symptoms began. Repeat the screener to monitor change after treatment or coaching. Decisions should rely on comprehensive assessment, not a single score.

FAQs

Is this calculator a diagnosis tool?

No. It is a screening aid that summarizes symptom frequency. Only a qualified clinician can diagnose ADHD using a full assessment, history, and differential evaluation.

What does a positive Part A screen mean?

A Part A shaded count of 4 or more suggests symptoms are consistent with adult ADHD and follow‑up assessment may be helpful. It does not confirm ADHD by itself.

Why do some items endorse at Sometimes+?

Certain questions are more sensitive at lower frequencies, so the endorsement threshold varies by item. This mirrors common scoring guidance for the screener’s shaded boxes.

Can I use it to track progress over time?

Yes. Repeating the same form under similar conditions can help you monitor changes in frequency. Use trends as discussion material, not as proof of improvement or worsening.

What if I also have stress, anxiety, or poor sleep?

These can mimic or worsen attention problems. If scores are elevated, consider addressing sleep, mood, and substance use and discuss overlap with a clinician for accurate interpretation.

How should I share the results?

Use the CSV or PDF export for appointments. Add examples of real‑life impact and when symptoms started. Keep personal data private and share only with trusted professionals.
