If you've taken the Adult ADHD Self-Report Scale (ASRS) and stared at those gray shaded boxes wondering what they mean, you're not alone. The ASRS uses a unique visual scoring system that trips up patients and clinicians alike.
This guide breaks down exactly how the shaded boxes work, why different questions have different thresholds, and how to interpret your results correctly.
What Are the Shaded Boxes on the ASRS?
The ASRS questionnaire uses darkly shaded boxes to indicate clinically significant responses. When your answer falls within a shaded area, it counts as a "positive" response for that symptom.
Here's the key insight: not all questions have shading in the same places.
Some questions consider "Sometimes" a clinically significant frequency, while others only count "Often" or "Very Often." This asymmetry reflects how different ADHD symptoms manifest—some are concerning even at lower frequencies, while others need to occur more often to be meaningful.
The scoring works like this:
- Answer in an unshaded box = 0 points
- Answer in a shaded box = 1 point
Simple enough in theory. The confusion comes from figuring out which boxes are shaded for which questions.
ASRS Part A Scoring: The 6-Question Screener
Part A contains the six questions most predictive of adult ADHD. These questions were identified through research as the best initial screening items, which is why many clinicians use Part A alone as a quick screener.
Questions 1-3: Lower Threshold (Sometimes or Higher)
For the first three questions, the shaded boxes begin at "Sometimes":
| Response | Score |
|---|---|
| Never | 0 |
| Rarely | 0 |
| Sometimes | 1 |
| Often | 1 |
| Very Often | 1 |
These questions assess:
- Trouble wrapping up final details of projects
- Difficulty getting organized for tasks
- Problems remembering appointments or obligations
These inattentive symptoms are considered significant even when they occur "sometimes" because they directly impact daily functioning.
Questions 4-6: Higher Threshold (Often or Higher)
For questions 4-6, the shaded boxes begin at "Often":
| Response | Score |
|---|---|
| Never | 0 |
| Rarely | 0 |
| Sometimes | 0 |
| Often | 1 |
| Very Often | 1 |
These questions assess:
4. Avoiding or delaying tasks requiring sustained thought
5. Fidgeting or squirming when seated
6. Feeling overly active or "driven by a motor"
The higher threshold for these items reflects that occasional procrastination or restlessness is common in the general population. Only when these behaviors occur "often" or more do they suggest ADHD.
Part A Scoring Summary
Add up all your shaded-box responses (0-6 possible points).
- Score of 4 or higher = Positive screen for adult ADHD
- Score of 0-3 = Negative screen
A positive screen means your symptoms are consistent with adult ADHD and warrant further professional evaluation. It does not mean you have ADHD—only a comprehensive clinical assessment can determine that.
Why Different Questions Have Different Thresholds
You might wonder why the ASRS doesn't just use the same threshold for every question. The answer lies in how ADHD symptoms present in the general population versus people with ADHD.
Inattention symptoms (Questions 1-3) like forgetting appointments or struggling to organize tasks are relatively specific to ADHD. Most adults without ADHD rarely experience these issues, so even occasional occurrence is meaningful.
Hyperactivity symptoms (Questions 5-6) like fidgeting or feeling restless are more common in the general population due to stress, caffeine, anxiety, or simply having an active personality. The higher threshold filters out normal variation.
Task avoidance (Question 4) is extremely common—almost everyone procrastinates sometimes. Only when avoidance becomes a frequent pattern does it suggest ADHD-related executive dysfunction.
This differential threshold approach improves the ASRS's ability to distinguish ADHD from normal variation, reducing both false positives and false negatives.
ASRS Part B Scoring: The Remaining 12 Questions
Part B (questions 7-18) doesn't have a numerical cutoff score like Part A. Instead, these questions provide additional clinical context about symptom patterns.
How to Use Part B
Clinicians review Part B responses to:
- Identify specific symptom clusters (primarily inattentive vs. hyperactive-impulsive)
- Understand symptom severity across domains
- Guide follow-up questions during clinical interviews
- Track symptom changes over time during treatment
Part B Shaded Box Pattern
Part B uses the same two-threshold system as Part A. Some questions have shading starting at "Sometimes," others at "Often." The exact pattern varies by question, following the same logic: symptoms that are more specific to ADHD have lower thresholds.
When interpreting Part B, pay attention to:
- Total number of shaded responses (more = more symptoms)
- Which symptom domains are affected (attention, hyperactivity, impulsivity)
- Severity patterns (mostly "Often" vs. mostly "Very Often")
Alternative Scoring Methods
While the shaded-box method is the original and most common scoring approach, some clinicians use an alternative numerical scoring system:
| Response | Points |
|---|---|
| Never | 0 |
| Rarely | 1 |
| Sometimes | 2 |
| Often | 3 |
| Very Often | 4 |
Using this method for the 6-question screener (Part A):
- Score range: 0-24 points
- Positive screen: 14 or higher
For the full 18-question assessment:
- Score range: 0-72 points
- Positive screen: Typically 17+ on the full scale
This numerical approach provides more granular information about symptom severity but requires different cutoff scores than the shaded-box method. Make sure you know which scoring system was used when interpreting results.
How to Interpret Your ASRS Results
Positive Screen (4+ on Part A)
A positive screen indicates that your symptom pattern is consistent with adult ADHD. Research shows approximately 67% of people who screen positive on the ASRS receive an ADHD diagnosis after comprehensive evaluation.
Next steps after a positive screen:
- Schedule an evaluation with a psychiatrist, psychologist, or ADHD specialist
- Gather information about childhood symptoms (ADHD requires symptom onset before age 12)
- Consider whether other conditions might explain your symptoms
- Complete the full ASRS if you only took Part A
Negative Screen (0-3 on Part A)
A negative screen suggests ADHD is less likely but doesn't rule it out completely. The ASRS has excellent sensitivity (about 91%) but some people with ADHD—particularly those with primarily inattentive presentations or strong coping mechanisms—may score below the threshold.
If you have a negative screen but still suspect ADHD, consider:
- Discussing your concerns with a clinician anyway
- Exploring whether anxiety, depression, or other conditions better explain your symptoms
- Retaking the assessment during a period of high stress when symptoms may be more apparent
Important Limitations
The ASRS is a screening tool, not a diagnostic instrument. High scores don't confirm ADHD, and low scores don't rule it out. Several factors can affect accuracy:
- Comorbid conditions: Anxiety and depression can cause ADHD-like symptoms
- Masking: Some people unconsciously minimize or underreport symptoms
- Life circumstances: Acute stress can temporarily increase symptoms
- Self-awareness: Some symptoms may be so habitual you don't recognize them
A comprehensive ADHD evaluation includes clinical interviews, developmental history, collateral information from family members, and often neuropsychological testing.
Frequently Asked Questions
What does it mean if I score exactly 4 on Part A?
A score of 4 is the threshold for a positive screen. This means your symptoms are consistent with ADHD and warrant further evaluation. You're not "borderline"—the cutoff was chosen to maximize detection of true ADHD cases while minimizing false positives.
Can I use the ASRS to diagnose myself with ADHD?
No. The ASRS is a screening tool that identifies people who should seek professional evaluation. Only a qualified clinician can diagnose ADHD after a comprehensive assessment that includes clinical interview, history review, and ruling out other conditions.
Why did my therapist score my ASRS differently than I expected?
Different scoring methods exist. The shaded-box method (binary 0/1 scoring) and the numerical method (0-4 points per question) use different cutoffs. Additionally, some versions of the ASRS have slightly different shading patterns. Confirm which version and scoring method was used.
Should I take the 6-question screener or the full 18-question version?
For initial screening, the 6-question Part A is sufficient and well-validated. If you screen positive, completing the full 18 questions provides more detailed information about your symptom profile. Many clinicians prefer the full version for treatment planning purposes.
How often should I retake the ASRS?
For treatment monitoring, retaking the ASRS every 3-6 months can help track symptom changes. During stable periods, annual reassessment is typically sufficient. More frequent assessment may be useful when starting or adjusting medication.
