What is

Asthma Control Questionnaire

The Asthma Control Questionnaire (ACQ) is a widely used tool that assesses asthma control and guides treatment decisions. It measures symptoms, rescue medication use, and airway obstruction to provide a comprehensive picture of asthma severity. The ACQ typically includes 5-7 items that ask about symptoms over the past week, with response options ranging from 0 (no symptoms) to 6 (severe symptoms). Clinicians and researchers use the ACQ to monitor changes in asthma control over time, identify areas for improvement, and evaluate the effectiveness of treatments. By assessing asthma control, healthcare providers can make informed decisions about medication adjustments and other interventions to improve patient outcomes. The ACQ is an important tool in both clinical practice and research, helping to optimise asthma management and improve quality of life for individuals with asthma, and its use is supported by various respiratory organisations.

Scoring

The Asthma Control Questionnaire can be scored using one main approach with variations in recall period. 1. The score is calculated by averaging the responses to 7 questions, covering symptoms, rescue medication use, and airway limitation, with each item scored on a 7-point scale (0 = no impairment to 6 = maximum impairment). The total score ranges from 0 (totally controlled) to 6 (severely uncontrolled), with a score of ≤0.75 indicating well-controlled asthma and ≥1.5 indicating poorly controlled asthma. Different versions (ACQ-5, ACQ-6, ACQ-7) vary in whether they include FEV1 and the recall period (1 week or 4 weeks), but the scoring principle remains the same.
