    Validity and Reliability of the Assessment Tool for Asthma (ATA) Questionnaire: the ATA Study
    (AVES, 2020) Baygül, Arzu; Gemicioğlu, Bilun; Mungan, Dilşad; ., ve diğer.
    OBJECTIVES: A multicenter trial was designed to validate the "Assessment Tools for Asthma (ATA)" questionnaire, a newly developed questionnaire, 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 100 randomized cases. ATA is an eight-item physician-administered questionnaire. It comprises the following two sections-ATA1, assesses symptomatic control criteria, and the remaining section, queries the flare-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 to the 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 flare-ups between visits, 96.4% patients had uncontrolled comorbidity, 17% patients had irregular asthma treatment, and only 8.4% patients used the incorrect inhaler technique. The ATA questionnaire showed internal consistency (Cronbach's alpha coefficient=0.683). ACT, ATA1, and two specialists' evaluations using VAS correlated strongly with the ATA total scores (Spearman correlation coefficient (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%, specificity=82.40%).

    Objective: A multicenter trial was designed to validate the “Assessment Tools for Asthma” (ATA) questionnaire, a newly developed questionnaire, which evaluates both asthma control and risk factors associated with control in the one instrument. 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. Visual analog scale (VAS) was used to evaluate the control status of 100 randomized cases. ATA is a physician-administered questionnaire including eight items. The ATA comprises two sections: the ATA1 querying symptomatic control criteria and the remaining section querying flare-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 to the ATA questionnaire, among all patients, 34.3% had controlled, 18.8% had partly controlled, and 46.9% had uncontrolled asthma. Further, 16.6% patients had flareups between visits, 96.4% patients had uncontrolled comorbidity, 17% patients had irregular asthma treatment, and only 8.4% patients used the incorrect inhaler technique. The ATA questionnaire showed internal consistency (Cronbach’s alpha coefficient = 0.683). ACT, ATA1, and two specialists’ evaluations using VAS were highly correlated to ATA total scores; the Spearman correlation coefficient (r) values were 0.776, 0.783, and 0.909, and p values were p<.001, p<.001, and p<.001, respectively. According to ROC (Receiver Operating Characteristic) analysis, the cut-off value of ATA was 50 (sensitivity=84.4%, specificity=82.40%). Conclusions: The validated ATA questionnaire may be a practical tool for physicians in asthma management.
