• The American version of the SGRQ (SGRQ-A, adapted from the original British English version) consists of 76 items in three domains:
  1) Symptoms
  2) Activity
  3) Impact of disease on daily life
• Part 1 (first 8 questions) asks for symptom recall of the previous 4 weeks; this is a change from the previous version of the SGRQ.
• There are versions with 3-month and 1-year symptom recall domains.
• A total score is calculated from 0 (no health impairment) to 100 (maximum health impairment).
• In addition to the total score, there is also a score for each domain: symptoms, activity, and impact which are scored 0 – 100 as well.
• Dyspnea is not measured specifically, but it is included in the symptom scale, along with information about cough, sputum production, and wheezing.
• Test items are weighted and scored using an Excel calculator.

COPD: (Jones, 2005; literature review)

• MDC = 4

Pulmonary Rehabilitation:(Schunemann et al, 2003;n= 84 patients who completed the CRQ, SGRQ, and FT before beginning pulmonary rehabilitation and 3 months later; mean age = 65.8 (7.6) years)

• MCID = 4

COPD:(Ferrer et al, 2002;n= 862 probable cases of COPD, 460 of which were eligible to complete the SGRQ; sex = 533 males and 329 females; age range 40-69 years)

• Education

  • Attended High School or University: 42.5%

  • Attended Primary/No School: 56.7%

• Smoking Status

  • Never Smoke: 52.7%

  • Former Smoker: 24.1%

  • Smoker >20 pack-yrs: 13.2%

  • Smoker <20 pack-years: 10.0%

• Respiratory Disease

  • COPD: 10.2%

  • Asthma: 3.6%

COPD/Pulmonary Disease:(Barr et al,2000;n= 102 patients with COPD (92 patients with COPD who completed the retest and 75 patients who completed the entire pulmonary rehabilitation program); mean age = 68 (9.34) years)

COPD:(Ketelarrs et al, 1996;n= 126 patients with COPD who were recruited on admission to a pulmonary rehabilitation center; mean age = 65 (9) years)

• Poorinterrater reliability for symptoms (Chronbach alpha = 0.60)

• Excellentinterrater reliability for activities (Chronbach alpha = 0.82)

• Adequateinterrater reliability for impact (Chronbach alpha = 0.71)

COPD / Pulmonary Disease:(Barr et al, 2000)

Internal Consistency of the American translation of the St. George’s Respiratory Questionnaire (SGRQ-A):

COPD / Pulmonary Disease:(Rutten-Van Molken, 1999;n= 144 patients with moderate or severe COPD) and (Hajiro, 1998; patients with chronic obstructive pulmonary disease)

• Poor to adequateconstruct validity for all components(r= 0.30-0.72)
• Discriminate validity was demonstrated when all components of the SGRQ-A with the modified 1-month symptom-reporting period were shown to discriminate better between disease-severity groups

COPD / Pulmonary Disease:(Barr et al, 2000)

• Adequatefloor and ceiling effects (<3%)

COPD/Pulmonary Disease:(Harper et al, 1997;n =156 patients with COPD attending routine outpatient clinic; 76 males; mean age = 67 (10.4) years; 80 females; mean age = 62 (10.3) years)

• Good responsiveness (intervention: pulmonary rehab)

• Responsiveness of the SGRQ-A to changein health status was demonstrated whenscores on the symptoms 1-month and total1-month components detected significantimprovements in patients’ health status(p= 0.02 andp= 0.04)
