Abstract 

The St George's Respiratory Questionnaire (SGRQ) is a self-administered questionnaire designed to measure quality of life (QOL) covering three areas (symptoms, activity and impacts) in patients with chronic obstructive pulmonary disease (COPD). The aim of the present study was to develop a Chinese version of the SGRQ (SGRQ-HK) and assess its psychometric properties. A forward and back-translation method was used, which included professional and lay people. Psychometric and clinical evaluations included 54 patients with COPD (31 males: mean age, 71.22 ± 5.95 years; 23 females: mean age, 68.8 ± 8.64 years). An additional QOL questionnaire and clinical and physiological data were also collected. The correlation coefficient between “symptoms” and dyspnoea was 0.67, that between “activity” and the 6-minute walk test was −0.78, between “impacts” and “mental health” of the SF-36 Health Survey Mental Health Inventory was −0.62; and between “total” and “general health” of the SF-36 was −0.87. Cronbach's a ranged from 0.74 to 0.95 for the whole questionnaire and its three subscales. Test-retest reliability showed intraclass correlation coefficients of all the dimensions exceeding 0.70. The three-factor structure of the SGRQ-HK was established. In conclusion, the SGRQ-HK is reliable and valid and compares well with the original English version.
