ACQ patient questionnaire

Accessed Oct 2019

The ACQ patient questionnaire is available at www.qoltech.co.uk/acq.html

Standout Feature:

  • Can be completed in 2-3 minutes  

Key Elements:

  • Simple, 7 items, multi-dimensional construct assessing symptoms (5 items--self-administered) and rescue inbronchodilator use (1 item-self-administered), and FEV1% (1 item) completed by clinic staff
  • 7 point scale (0=no impairment, 6= maximum impairment for symptoms and rescue use; and 7 = categories for FEV1%)
  • Strong discriminative and evaluative properties  
  • Control level, as well as changes in asthma control (either spontaneously or via treatment), is calculated from mean score
  • Symptoms data is collected with 1 week recall • Scores range between 0 (totally controlled) and 6 (severely uncontrolled) • Validated for paper and phone administration, and available in over 60 different languages, with cultural adaptations                                                                                                     
  • Formats include paper, interactive web, and various electronic devices
  • Required permission from author, Professor Elizabeth Juniper: juniper [at] qoltech [dot] co [dot] uk  

Potential Limitations:  

  • Results cannot be analyzed by “eyeballing”
  • Not designed to differentiate between daytime and nighttime asthma control  
  • A fully validated, interviewer-administered version of the adult ACQ has been developed for children 610 years, but not for children less than 6 years of age; this version must be administered by a trained interviewer
  • All 3 dimensions (self-administered questionnaire, rescue bronchodilator use and FEV1%) must be measured; otherwise, there is a risk of estimating asthma control inaccurately in individual patients
