The Asthma Control Test (ACT), introduced in 2003, is a validated brief questionnaire which consists of 5 questions for adults and 7 questions for children. ACT is designed to assess the level of asthma control and it correlates well with PFTs.
The ACT is reliable, valid, and responsive to changes in asthma control over time. A cutoff score of 19 or less identifies patients with poorly controlled asthma. An ACT score of 19 or less provides optimum balance of sensitivity (71%) and specificity (71%) for detecting uncontrolled asthma.
