Working groups and survey development
A working group composed of primary care clinicians (n = 4) and of leading asthma specialists (n = 7) was convened to advise on the development of a tool for assessing control. The working group participants represented a range of geographic regions in the United States. The working group helped to specify the components of asthma control that should be assessed by the survey and participated in defining a criterion measure of asthma control that would be used in evaluating the survey's
Sample
Four hundred seventy-one patients completed the survey. Of the 471 respondents, 407 (86.4%) completed all 22 survey items. The average age of respondents was 45.2 years (SD, 18.5) with a range of 12 to 94 years. Approximately 14% of the sample was age 65 years or older, and 12% were younger than 20 years of age. The majority of the sample had asthma that was well controlled (52.2%) or completely controlled (18.1%) according to the specialist's rating of asthma control. The mean percent
Discussion
The 5 items empirically selected for the ACT survey parallel the dimensions of asthma control that underlie current asthma management guidelines—asthma symptoms, use of rescue medications, and the impact of asthma on everyday functioning—and support the premise that asthma control is a multidimensional construct. In this study, scores computed from ACT were shown to be reliable and valid, and the test as a whole shows promising ability to screen for patients with poorly controlled asthma.
