Validation Of The Asthma Self-Management Questionnaire For The Brazilian Population.

Introduction: The lack of instruments to assess asthma self-management in Brazil highlights the need to develop specific tools to help patients manage their own health condition.

Objective: The study aimed to translate, cross-culturally adapt, and evaluate the psychometric properties of the Asthma Self-Management Questionnaire (ASMQ) for the Brazilian adult population diagnosed with asthma.

Materials and methods: This is a methodological, exploratory, and descriptive study approved by the Research Ethics Committee (CEP) of the Federal University of Rio Grande do Norte (UFRN) under opinion number 6.062.022. The study followed international guidelines to design and execute six stages: translation, synthesis of translations, back-translation, synthesis of back-translations, Multidisciplinary Committee of Experts, and pre-testing. For the translation phase, five judges participated using the Delphi Technique through the Multidisciplinary Committee of Experts. For the cross-cultural adaptation, a pre-test phase was conducted using a questionnaire applied to individuals who met the eligibility criteria. Data analysis was performed using SPSS statistical software, version 22.0, with a significance level of 5%.

Results: The translation and cross-cultural adaptation of the ASMQ-Brazil to Brazilian Portuguese were completed. The results of this study demonstrated a Content Validity Index (CVI) greater than 0.80 for all items in the instrument. The ASMQ-Brazil is presented as a valid and reliable health measurement instrument for assessing asthma self-management in the Brazilian adult population.
