Abstract

Given the identified need to measure outcomes in terms of activity limitation and participation restriction, the authors evaluated the test-retest reliability of the Patient-Specific Functional Scale and the London Handicap Scale for people with chronic obstructive pulmonary disease (COPD). Twelve people with moderately severe COPD were measured on two occasions separated by a 2-week interval. Severity of COPD was determined using British Thoracic Society guidelines on lung function measures. Reliability coefficients for the Patient-Specific Functional Scale and London Handicap Scale were 0.55 and 0.71 respectively. To be 95% confident that real change had occurred, groups would need activity scores to increase by 1 out of 10 and handicap scores to increase by 6 out of 100. For individuals, changes in activity scores of 2 out of 10 and handicap scores of 17 out of 100 would be required. These results indicate that both scales could be suitable for testing hypotheses in groups of people with COPD. However, only the Patient-Specific Functional Scale is likely to be able to detect and monitor changes in individuals.
