How To Score ASRS v1.1 | Clean Steps, No Guesswork

The ASRS v1.1 looks like a simple grid, yet scoring can get messy fast. The shaded area doesn’t start in the same column on every row, so a rushed count can flip the result.

This walk-through shows the mechanics that the official forms describe: what counts, what doesn’t, and how to record the result so it stays usable in a chart, a referral packet, or your own notes.

What The ASRS v1.1 Measures And What It Doesn’t

ASRS v1.1 is a self-report checklist about how often ADHD-related symptoms show up over the past six months. It’s a screen, not a diagnosis. A score can’t confirm onset, impairment, or rule‑outs on its own.

If your result raises questions, the next step is a full evaluation with a licensed clinician. Diagnosis involves more than a questionnaire score, including history, impairment, and rule‑outs.

Before You Score Anything, Pick The Right Form

You’ll see ASRS v1.1 shared in two common layouts. Scoring starts the same way, yet the goal differs.

6‑Question Screener

This is Part A only. You count shaded-box hits across the six items. Some users also apply a 0–24 point method from Harvard that turns each response into a point value.

Use a copy where the shaded boxes are visible. If your copy is faded or a web form removed the shading, score from an official PDF or use the cutoff table later in this article.

18‑Question Symptom Checklist

This includes Part A (items 1–6) plus Part B (items 7–18). Part A drives the screen-positive flag. Part B adds detail on the symptom mix so a clinician can ask tighter follow-up questions.

Two Setup Checks That Prevent Bad Scores

• Timeframe: Answer using the past six months, as written on the form.
• No blanks: Get one marked answer for every item before scoring.

If you’re scoring a paper copy that was photocopied too lightly, the shaded areas can fade. In that case, use the cutoff table in this article or score from an official PDF where the shaded region is clear.

How To Score ASRS v1.1 Step By Step Using Shaded Boxes

The classic method is binary per item: shaded-box hit (1) or not (0). The cutoff is shown by where the shaded area begins on that row.

Step 1: Confirm The Response Scale

The options run from “Never” through higher-frequency choices. Each item gets one marked box. If someone circles between two options, ask them to pick the closer one before you score.

Step 2: Treat The Shaded Area As The Cutoff

If the marked box sits inside the shaded area, that item counts. If it’s outside, it doesn’t. You don’t add numbers across columns in the shaded-box method. You only count hits.

Step 3: Count Part A Hits And Flag The Screen

Add the shaded-box hits across Part A (items 1–6). The instruction printed on the screener says that 4+ Part A hits means a positive screen.

If you’re documenting for clinical use, write the count as “4/6” instead of a loose label. That keeps the result clear even if the person retakes the form later.

Step 4: Read Part B As Pattern

On the 18‑item form, Part B is extra detail. The original checklist notes don’t assign a single diagnostic total to Part B.

A quick way to scan Part B is to group items by symptom type. The inattention-related items are 1–4 and 7–11. The hyperactive/impulsive items are 5–6 and 12–18. You’re not “scoring a subtype” with this screen, yet the pattern can help a clinician choose what to ask next.

Step 5: Record The Result In One Line

Write version, method, Part A count, and date. Sample notes:

• Shaded-box method: “ASRS v1.1 shaded-box: Part A 4/6, screen positive, YYYY‑MM‑DD.”
• Point method (6Q only): “ASRS v1.1 points: total 16/24, screen positive, YYYY‑MM‑DD.”

Item	Shaded Cutoff	Symptom Theme
1	Sometimes+	Finishing details
2	Sometimes+	Organization
3	Sometimes+	Appointments
4	Often+	Starting tasks
5	Often+	Fidgeting
6	Often+	Feeling driven
7	Often+	Careless mistakes
8	Often+	Sustaining attention
9	Sometimes+	Listening focus
10	Often+	Misplacing items
11	Often+	Distractibility
12	Sometimes+	Leaving seat
13	Often+	Restlessness
14	Often+	Unwinding
15	Often+	Talking a lot
16	Sometimes+	Finishing sentences
17	Often+	Waiting turn
18	Sometimes+	Interrupting

How to read the table: “Sometimes+” means Sometimes, Often, or the last column on the scale. “Often+” means Often or the last column. This matches the shaded-box pattern used on standard ASRS v1.1 forms.

Scoring The 6‑Question Screener With Points

Alongside the shaded-box count (0–6), Harvard posted a point-total option for the 6‑question screener. It assigns 0–4 points per response, sums the six items for a 0–24 total, and flags a positive screen at 14+.

Point mapping (left to right): Never = 0, Rarely = 1, Sometimes = 2, Often = 3, last column = 4. Add the six item scores to get the total.

The same memo groups totals into bands: 0–9 (low negative), 10–13 (high negative), 14–17 (low positive), 18–24 (high positive). Those bands help when you want a little more gradation than a simple 0–6 hit count.

If you want to use that method, keep the source memo with your paperwork: ASRS v1.1 Scoring Update (PDF).

Pick one scoring method per person and stick with it. Mixing methods turns tracking into noise.

How To Read Your Result Without Overreaching

A positive screen means the questionnaire pattern lines up with ADHD symptoms often enough to justify a deeper evaluation. A negative screen means this tool didn’t flag that pattern strongly.

That’s all the screen can say. Clinicians still check impairment, age of onset, symptom pattern across settings, and whether another condition better fits the picture. The American Psychiatric Association’s overview of ADHD in adults gives a plain-language explanation of how ADHD can show up in adult life and why history still matters. The CDC’s ADHD diagnosis overview lists the extra steps that sit outside a screening score.

• Frequency isn’t impairment. A high-frequency answer doesn’t tell you how much it disrupts work, home, or relationships.
• Overlap happens. Sleep loss, anxiety, depression, substance use, thyroid problems, and some medications can mimic parts of the checklist. A clinician sorts that out.
• Context matters. A rough week can spike answers. A calmer stretch can lower them. That’s why the form uses a six‑month window.

Common Scoring Mistakes That Flip The Outcome

Marking Every “Sometimes” As A Hit

Only certain items treat “Sometimes” as shaded. Use the form’s shaded area, or use the cutoff table above.

Inventing A Part B Total

On the 18‑item checklist, Part A drives the screen-positive flag. Part B adds detail. The original checklist notes don’t give Part B a single diagnostic total.

Scoring With Missing Answers

A blank is not a zero. Get a marked response, then score.

Letting The Time Window Drift

If answers were based on “this week” or “my worst month,” redo the form using the past-six-month window.

Using A Version That Lost The Shading

Some web forms strip shading, and some photocopies fade it. If the shading isn’t visible, score from the official PDF or follow the cutoff table so the hit count stays faithful to the original layout.

Step	Write Down	Keep It Useful
Version	ASRS v1.1 (6Q) or (18Q)	Avoid mixing layouts
Method	Shaded-box or 0–24 points	Avoid mixing scoring systems
Part A Count	Part A = 4/6	Shows the threshold directly
Point Total	Total = 16/24	Only if you used points
Date	YYYY‑MM‑DD	Ties the score to a period of life
Context Notes	2–3 lines (sleep, meds, stress)	Helps interpretation
Next Step	Shared with clinician / booked eval	Keeps the score tied to action

How To Bring The Score Into A Real Evaluation

A single number is easy to share, yet clinicians get more value from the marked form and a few real-life examples tied to the highest-frequency items. If you’re preparing for an appointment, treat the score as an entry point and bring the details that sit behind it.

Bring The Marked Form

Part A = 4/6 is useful, yet the checked boxes show the symptom mix. Bring the page or a clear scan so the clinician can see which items drove the count.

Add Short Examples

Two brief examples per high-frequency item is plenty. Stick to what happened, where it happened, and the outcome. That keeps the visit grounded in real function, not only checkboxes.

Note Onset And Settings

Clinicians often ask when these patterns started and whether they show up across settings like work and home. If you can sketch that in a few lines, it speeds up the history portion of the evaluation.

Using ASRS v1.1 For Tracking

If you repeat the ASRS to track change during treatment, keep the setup consistent so you can compare one score to the next.

• Use the same version each time (6Q or 18Q).
• Use the same scoring method each time.
• Keep brief notes on big changes (sleep, meds, workload).

Two-Minute Scoring Checklist

• All items answered with one marked box.
• Past-six-month timeframe used.
• Count Part A shaded-box hits (1–6).
• Screen positive at 4+ Part A hits.
• If using points, total the six items and screen positive at 14+.
• Record version, method, count or total, and date.
