Asthma Control Questionnaire Helper

This tool helps you score and interpret your Asthma Control Questionnaire (ACQ) results offline. It's designed for adults and adolescents (12+) to track asthma control over time, understand typical interpretation bands, and prepare better questions for your healthcare team.

Educational only, not medical advice. This tool does not diagnose or provide treatment recommendations.

ACQ Calculator

Rate your asthma over the past week (0=No impairment, 6=Maximum impairment)

1. Nighttime waking due to asthma

2. Morning symptoms (cough, wheeze, chest tightness)

3. Activity limitation due to asthma

4. Shortness of breath due to asthma

5. Wheezing due to asthma

6. Rescue bronchodilator use (puffs per day)

7. FEV₁ % Predicted (optional)

Show

Enter your FEV₁ % predicted value if available (typically 40-130%). Leave blank for ACQ-6 scoring.

Understanding Your Asthma Control Score

The Asthma Control Questionnaire (ACQ) is a validated tool used clinically to measure how well your asthma is controlled over the previous week. Tracking this score over time can help you and your clinician identify patterns and adjust management plans.

How to Use This Tool

Answer all 6 questions about your symptoms and rescue inhaler use over the past week.
If you have a recent spirometry result with FEV₁ % predicted, you can optionally include it for the ACQ-7 score.
Review your score and the typical interpretation band.
Use the "What to Discuss" checklist below to prepare for your next medical appointment.

Example Scenarios

Scenario	Typical Scores	Interpretation
Well-controlled asthma	0.0 - 0.75	Minimal symptoms, no nighttime waking, rescue use ≤2 days/week.
Partly controlled asthma	0.76 - 1.50	Some limitations, symptoms or rescue use several days per week.
Uncontrolled asthma	>1.50	Frequent symptoms, nighttime waking, daily rescue use.

Important Notes

ACQ scores are not a diagnosis. They are one measure of control.
Scores can vary week-to-week based on triggers, seasons, or infections.
A single high score doesn't necessarily mean your treatment isn't working.
Always discuss trends and concerns with your healthcare provider.

What to Discuss with Your Clinician

Use this interactive checklist to prepare for your next appointment. Checking items will generate a summary.

Frequently Asked Questions

How accurate is this ACQ calculator?

This tool uses the standard ACQ scoring algorithm identical to clinical versions. However, it relies on your accurate recall of symptoms over the past week. In-clinic assessments may include additional clinical judgment.

Should I use ACQ-6 or ACQ-7?

ACQ-6 (without FEV₁) is sufficient for most self-assessment. ACQ-7 includes lung function and may be used if you have recent spirometry results. Both are valid; consistency (using the same version each time) is most important for tracking.

What if my score is high (>1.5)?

A consistently high score suggests suboptimal control. This doesn't mean your treatment has failed, but it's important to discuss with your clinician. Don't change medications without professional guidance.

How often should I complete the ACQ?

For tracking, weekly completion is typical. Complete it at the same time each week for consistency. Seasonal variations are common, so long-term trends (over months) are more informative than single scores.

Formulas & Assumptions

• ACQ-6 Score = (Sum of questions 1-6) ÷ 6
• ACQ-7 Score = (Sum of questions 1-6 + FEV₁ score) ÷ 7
• FEV₁ scoring: 0=≥100%, 1=95-99%, 2=90-94%, 3=85-89%, 4=80-84%, 5=75-79%, 6=≤74% predicted
• Interpretation bands based on clinical validation studies: <0.75=well-controlled, 0.75-1.50=partly controlled, >1.50=uncontrolled
• Rounding: Scores rounded to 2 decimal places for display; calculations use full precision
