OBJECTIVES: A multicenter trial was designed to validate the “Assessment Tools for Asthma (ATA)” questionnaire, a newly developedquestionnaire, which evaluates both asthma control and risk factors associated with asthma control with a single instrument.MATERIALS AND METHODS: This cross-sectional study involved 810 cases from 14 clinics in 9 Turkish cities. The ATA questionnaire and Asthma Control Test (ACT) were administered. The Visual Analog Scale (VAS) was used to evaluate the control status of 100randomized cases. ATA is an eight-item physician-administered questionnaire. It comprises the following two sections-ATA1, assessessymptomatic control criteria, and the remaining section, queries the flre-up of asthma, control of comorbidities, treatment adherence,and inhaler technique.RESULTS: The mean scores for ATA1, ATA total, VAS, and ACT were 24.7±14.8, 53.8±19, 7.1±3, and 18.8±5.5, respectively. According tothe ATA questionnaire, among all patients, 34.3% had controlled, 18.8% had partly controlled, and 46.9% had uncontrolled asthma. Furthermore, 16.6% patients had flre-ups between visits, 96.4% patients had uncontrolled comorbidity, 17% patients had irregular asthmatreatment, and only 8.4% patients used the incorrect inhaler technique. The ATA questionnaire showed internal consistency (Cronbach’salpha coeffiient=0.683). ACT, ATA1, and two specialists’ evaluations using VAS correlated strongly with the ATA total scores (Spearmancorrelation coeffiient (r) values: 0.776, 0.783, and 0.909, respectively; p-values: p<0.001, p<0.001, and p<0.001, respectively). According to Receiver Operating Characteristic analysis, the cut-off value of ATA was 50 (sensitivity=84.4%, specifiity=82.40%).CONCLUSION: The validated ATA questionnaire may be a practical tool for physicians in asthma management.
