Asthma Control Questionnaire (ACQ): Symptom Assessment
The Asthma Control Questionnaire helps doctors and patients measure how well asthma is controlled. It assesses symptoms and medication use to provide a score that guides treatment decisions.
Asthma Control Questionnaire
The Asthma Control Questionnaire (ACQ) assesses how well a patient's asthma is managed. By tracking symptoms and lung function, it helps clinicians adjust treatments to minimise risk. This survey provides a clear score, ensuring respiratory health is monitored accurately in clinical practice.

What is Asthma Control Questionnaire
The Asthma Control Questionnaire (ACQ) is a trusted tool for checking asthma management. It helps doctors and patients track symptom stability. This validated survey looks at the main criteria for stable asthma. It mixes subjective patient reports with objective lung function data for a full view. Patients answer questions about waking up at night, morning symptoms, activity limits, shortness of breath, and wheezing. They also record rescue bronchodilator use. All items use a seven point scale where zero means well controlled and six means poor control. Clinicians use the full ACQ with seven items or shorter versions like the ACQ-5 that skip the lung function test. It is useful for clinical trials and routine visits because it spots health changes quickly. The score helps teams decide if they need to change treatment plans to keep lungs healthy.
The Asthma Control Questionnaire can be scored using a straightforward averaging approach. Patients answer questions on a 7 point scale ranging from 0 (no impairment) to 6 (maximum impairment). To get the final score, you just add up the response values and divide by the total number of questions answered. This gives a mean score between 0 and 6. Generally, a score below 0.75 suggests asthma is well controlled, while anything over 1.5 indicates it's not well controlled. Scores sitting in between fall into a grey area requiring clinical judgement.
