Abstract

OBJECTIVE: To develop and test an online assessment referred to as the ASTHMA-CAT (computerized adaptive testing), a patient-based asthma impact, control, and generic health-related quality of life (HRQOL) measure. STUDY DESIGN: Cross-sectional pilot study of the ASTHMA-CAT's administrative feasibility in a disease management population. METHODS: The ASTHMA-CAT included a dynamic or static Asthma Impact Survey (AIS), Asthma Control Test, and SF-8 Health Survey. A sample of clinician-diagnosed adult asthmatic patients (N = 114) completed the ASTHMA-CAT. Results were used to evaluate administrative feasibility of the instrument and psychometric performance of the dynamic AIS relative to the static AIS. A prototype aggregate (group-level) report was developed and reviewed by care providers. RESULTS: Online administration of the ASTHMA-CAT was feasible for patients in disease management. The dynamic AIS functioned well compared with the static AIS in preliminary studies evaluating response burden, precision, and validity. Providers found reports to be relevant, useful, and applicable for care management. CONCLUSION: The ASTHMA-CAT may facilitate asthma care management.
