Abstract

Background: There is a lack of questionnaires capable of evaluating the clinical control of Brazilian children and adolescents with asthma over a wide age range. The Pediatric Asthma Control and Communication Instrument (PACCI) has been validated, but only with English- and Spanish-speaking children in the United States. Objectives: To evaluate the psychometric properties of the Brazilian version of the PACCI questionnaire. Methods: A cross-sectional psychometric study conducted with children and adolescents aged 01 to 19 years with a clinical diagnosis of asthma, and their respective parents/guardians. The following assessments were conducted: socioeconomic status; clinical control using the Childhood Asthma Control Test (c-ACT), Asthma Control Test (ACT); caregiver quality of life using the Pediatric Asthma Caregivers Quality of Life Questionnaire (PACQLQ); and pulmonary function test (spirometry). Validity was evaluated as follows: exploratory and confirmatory factor analysis; Cronbach's alpha analysis (α); floor and ceiling effects; receiver operator characteristic curve analysis. Results: A total of 128 participants were included, most of them male (54.7%). The Brazilian version of PACCI had adequate internal consistency (α =.76) and moderate floor and ceiling effects. The internal structure presented acceptable adjustment indices, considering the extraction of four factors. The factors presented adequate α values. Asthma control factor 1 correlated with c-ACT/ACT and PACQLQ. Control domain scores greater than four points (sum of score) and above 1 point (problem index) were indicative of uncontrolled asthma. Conclusion: The Brazilian version of PACCI was able to provide valid and reliable measures in evaluating the clinical control of asthma in Brazilian children and adolescents.
