摘要

Background

The Bronchiectasis Health Questionnaire (BHQ), a 10-question instrument designed to assess quality of life and disease-specific issues, was developed in 11 languages, including English. The present study aims to translate the original version of the BHQ into Turkish using a standardised methodology and to evaluate the validity and reliability of the Turkish version of the BHQ.

Methods

This cross-sectional study was conducted at Giresun Training and Research Hospital between August 2024 and January 2025, with ethical approval (decision number 03.07.2024/03) and informed consent from all participants. A total of 132 clinically stable participants with bronchiectasis were enrolled. The study was performed in two stages: (1) cross-cultural adaptation of the original Bronchiectasis Health Questionnaire (BHQ) into Turkish (T-BHQ) according to established guidelines, and (2) psychometric validation of the T-BHQ. Alongside the T-BHQ, data on socio-demographics, clinical characteristics, mMRC dyspnea score, pulmonary function tests, Bronchiectasis Severity Index (BSI), SF-12 quality of life questionnaire, and exacerbation history were collected. Reliability was assessed using Cronbach’s alpha and test–retest analysis, while construct validity was evaluated through exploratory and confirmatory factor analyses, convergent validity with clinical measures, and Bland–Altman analysis.

Results

The validity and reliability of the T-BHQ were evaluated in present study involving a total of 134 participants with bronchiectasis, and a Cronbach’s alpha of 0.729 was obtained. In the exploratory factorial analysis, factorial loadings of > 0.40 were determined for all items and were evaluated as appropriate. Utilising the Bland-Altman analysis to assess the test’s repeatability, (mean difference: 0,059, β = 0.03, p:0.840). The convergent validity of the T-BHQ with mMRC was strong (r = − 0.648, p:< 0.001), with BSI were moderate (r: -0,437, p:<0,001), while concurrent validity with SF-12 subtypes mainly were at a moderate level (Physical role functioning: r = − 0.661 p:<0.001, other subtypes at a moderate level).

Conclusions

The T-BHQ has been demonstrated to possess both reliability and validity in evaluating the disease-related quality of life and health status of participants with bronchiectasis in Turkey.
