American translation, modification, and validation of the St. George's Respiratory Questionnaire.
The St. George's Respiratory Questionnaire (SGRQ) is a 50-item health status survey specific for chronic obstructive pulmonary disease (COPD) and other respiratory diseases that is available in British English but not American English. The SGRQ's symptom-reporting component requires a 1-year reporting period, which may be too long for reliable and accurate patient recall. ⋯ The SGRQ-A with a modified 1-month symptom-reporting period demonstrated reliability and validity in this sample of patients with COPD. Key words: chronic obstructive pulmonary disease, St. George's Respiratory Questionnaire, American translation, reliability, validity, symptom recall.
