Asthma Control Test (ACT)

Asthma-specific

Measure domains:   Symptom Control and Use of Rescue Inhalers

Summary of development:  The Asthma Control Test (ACT) was developed for people ages 12 and older.  An initial set of 22 questions was developed by clinicians.  A sample of patients completed the questions and their asthma control was rated by a specialist.  Stepwise logistic regression methods were used to identify the survey items with the greatest validity in discriminating between patients who differed in the specialist’s rating of asthma control.  The final questionnaire has 5 items (Nathan 2004).  The original articles included participants as young as 12 and they were included in the analyses.  There has been widespread use of this questionnaire since its development.  However, we were unable to find any psychometric testing of the ACT exclusively in an adolescent sample.
