Clinical Investigations: COPDValidation of the Hong Kong Chinese Version of the St. George Respiratory Questionnaire in Patients with Bronchiectasis
Section snippets
Translation Procedure
The SGRQ was translated into Chinese and then backtranslated into English using the methodology employed by a Spanish translation and validation study.12 The process involved the translation of the first version by a bilingual person, followed by a review by a committee of professionals (ie, two respiratory physicians, one respiratory nurse, and one research assistant). Back-translation into English and a comparison with the original version were performed by another bilingual person, and the
Subject Demography and Clinical Characteristics
Altogether, 93 bronchiectasis patients (mean [± SD] age, 59.0 ± 14.2 years; women, 61; current smokers, 2; ex-smokers, 17; and never-smokers, 74) were recruited prospectively between May 1999 and June 2000. The clinical characteristics of these patients are outlined in Table 1. Most of these patients had idiopathic bronchiectasis (75 patients), and the remaining patients had developed bronchiectasis due to pulmonary tuberculosis (11 patients), IgG deficiency (1 patient), diffuse
Discussion
The original SGRQ was developed in 1990 by Jones et al7 to quantify the impact of disease on the health and well-being of patients with COPD. Since then, the SGRQ has been translated into many languages and has been validated for use in different ethnic groups. To date, several adaptation and validation studies have been published in non-English populations.10,12,13,14,15,16,24 These studies were performed on Swedish, Spanish, Japanese, and American-English speaking populations, and have

The Saint George’s Respiratory Questionnaire (SGRQ)11–14 and the Chronic Respiratory Disease questionnaire14 were developed for individuals with chronic obstructive pulmonary disease and validated for bronchiectasis since both diseases present common clinical symptoms.11,13–15 These instruments are useful; however, they are extensive and time-consuming.

The Chinese version of HADS has been validated and showed good reliability in several studies conducted in the Mandarin-speaking area.23-26 All data analyses and statistical procedures were performed using SAS statistical software, version 9.4 (SAS Institute Inc).
