Asthma Control Test

The Asthma Control Test™ (ACT™) is a five question health survey used to measure asthma control in individuals 12 years of age and older. The survey measures the elements of asthma control as defined by the National Heart, Lung and Blood Institute (NHLBI). ACT™ is an efficient, reliable and valid method of measuring asthma control, with or without, lung functioning measures such as spirometry.

The development of the ACT™ follows a paradigm shift in the treatment of asthma, from a focus on asthma severity to asthma control. Specifically, ACT™ helps identify and detect asthma patients who are not well controlled. It was designed with input from asthma experts who helped establish cut-point scores to improve the clinical utility of the survey. Minimal important differences (MID) were also established for ACT™ to assist in the interpretation of the significance of score changes over time.

ACT™ is available with a standard four-week recall period in multiple language translations.
