BACKGROUND: The Bronchiectasis Health Questionnaire (BHQ) was developed to assess the health-related quality of life (HRQOL) in patients with noncystic fibrosis (CF) bronchiectasis. This study aimed to translate, culturally adapt, and validate the BHQ for use among Chinese patients.
METHODS: The traditional Chinese version of the BHQ (TC-BHQ) was created through a process of translation, cognitive debriefing interviews, and expert panel reviews. The psychometric evaluation of the TC-BHQ encompassed assessments of factor structure, convergent validity, known-group comparison, internal consistency, and test-retest reliability.
RESULTS: We recruited 150 non-CF bronchiectasis patients. Confirmatory factor analysis (CFA) supported the one-factor structure of the BHQ. In terms of concurrent validity, the TC-BHQ total score showed a significant correlation with the St. George's Respiratory Questionnaire (SGRQ) total score (r = -0.77, p < 0.01). In addition, the TC-BHQ total score significantly correlated with all SGRQ subscale scores, including the symptom score (r = -0.62, p < 0.01), activity score (r = -0.60, p < 0.01), and impact score (r = -0.75, p < 0.01). There was a statistically significant change in the total score between baseline and follow-up (p = 0.007). Both internal consistency and test-retest reliability of the TC-BHQ were acceptable.
CONCLUSION: TC-BHQ is a promising tool for assessing HRQOL in patients with non-CF bronchiectasis. It has the potential to be a useful instrument in both clinical and research settings.
