Validation and psychometric properties of the Asthma Control Questionnaire among children.

ABSTRACT:

Background

The Asthma Control Questionnaire (ACQ) is a patient-centered tool for evaluating asthma control. It has been validated in adults, but not well-validated among children.

Objective

We evaluated the reliability, validity, and responsiveness to change of the ACQ for assessing asthma control in children ages 6 to 17 years. A threshold value for poor disease control and a minimally important difference were also determined.

Methods

Data from 305 asthmatic children enrolled in a clinical trial were examined. The ACQ was administered at 8 visits. We analyzed results for the combined age group and for the 6- to 11-year-old and 12- to 17-year-old age groups separately.

Results

Overall, the Cronbach α value (internal consistency) for the ACQ was 0.74 at baselin
