Asthma Control Questionnaire

Asthma-specific

Measure domains: Symptom Control and Rescue Inhaler Use, plus a third component of forced expiratory volume in 1 second recorded by clinician

Summary of development:  This measure for adults and children is designed to be a brief assessment of the control one has over their asthma symptoms. Asthma experts from around the world were asked about the most relevant symptoms to determine the seven questions for this measure. From the list of symptoms, Juniper and colleagues (1999) identified the top 5: being woken at night by symptoms, waking in the mornings with symptoms, limitation of daily activities, shortness of breath and wheeze. Respondents are asked to rate the level of severity of their asthma when answering six questions; the 7th question is a test of forced expiratory volume, the amount of air you exhale in 1 second, recorded by a clinician. The ACQ has been validated for use in children aged 6–16 years, and children ages 6-10 have a trained interviewer administer the questionnaire (Juniper 2010).  Here, we only include validation information from the children’s version.
