Objective To cross‐culturally adapt the Pediatric Asthma Therapy Assessment Questionnaire (ATAQ) into Brazilian Portuguese and analyze its measurement properties. Methods This exploratory methodological study included eight experts and 30 caregivers in the translation and cross‐cultural adaptation steps. Thereafter, 118 caregivers of pediatric patients with asthma aged between 5 and 17 years were involved in the analysis of measurement properties. We analyzed the content, structural (exploratory and confirmatory factorial), construct (convergent and discriminant), and known‐groups validities; floor and ceiling effects; and determined the cut‐off point (receiver operator characteristic curve) to identify pediatric patients with uncontrolled asthma. Intraclass correlation coefficient (ICC) analyzed test−retest reliability with 54 caregivers, whereas Cronbach's α and composite reliability verified the internal consistency of the items. Results The committee of experts and caregivers found the instructions and response options relevant, understandable, and clear (K > 0.75). During the cross‐cultural adaptation, three items (2, 4, and 12) were slightly modified by including terms to facilitate understanding. A two‐factor structure (asthma control and patient‐provider communication) was identified. Internal consistency (α > .67; composite reliability > 0.73) and test−retest reliability (ICC > 0.80) were acceptable. For construct and know‐groups validities, 85.71% of the hypothesis were confirmed. A cut‐off point of >3 for the control domain was considered adequate to identify pediatric patients with uncontrolled asthma (sensitivity: 86.21%; specificity: 80.90%). Conclusion The Pediatric ATAQ was adequately adapted for Brazilian pediatric patients with asthma and produced valid and reliable measures for assessing asthma control. Therefore, it may be considered an adequate instrument for monitoring asthma control in the Brazilian pediatric population.
