| description | Introduction and objective: The Bronchiectasis Health Questionnaire (BHQ) is a simple, repeatable, and self-reporting health status questionnaire for bronchiectasis. This study aims to cross-culturally adapt the BHQ into Brazilian Portuguese and evaluate its measurement properties. Methods: The participants answered the Saint George...s Respiratory Questionnaire (SGRQ) and the modified Medical Research Council (mMRC) scale for dyspnea. The Brazilian-Portuguese version of the Bronchiectasis Health Questionnaire (BHQ-Brazil) was used at baseline (test) and after 14 days (retest). The psychometric analyses included internal consistency, test-retest reliability, and construct validity: factorial validity, convergent validity, and discriminative validity, agreement, and ceiling and floor effects. Results: The BHQ-Brazil demonstrated adequate internal consistency (Cronbach...s alpha...=...0.92) and substantial reliability (intraclass correlation coefficient...=...0.86; 95%CI: 0.79...0.90). The exploratory factorial analysis was considered suitable. All items presented a factorial load >0.40. The convergent validity of the BHQ-Brazil with mMRC was moderate (r...=......0.53, p...<...0.001), while concurrent validity with the SGRQ was strong (symptoms: r...=......0.72, activities: r...=......0.60, impact: r...=......0.60, total score: r...=......0.75, all p...<...0.001). The standard error of measurement was 4.81 points. The discriminative validity demonstrated that individuals with more pulmonary exacerbations, colonization by Pseudomonas aeruginosa, worst dyspnea, and a higher number of affected lung lobes presented the lowest quality of life. No floor or ceiling effects were observed. Conclusion: The BHQ-Brazil presents adequate measurement properties to evaluate the impact of bronchiectasis on health-related quality of life, and can be used in clinical and research settings. |
