“…The grade system suggested by Lacasse and colleagues was chosen for interpreting the correlation coefficients: coefficients of correlation between 0 and 0.20 were considered unimportant, between 0.21 and 0.35 weak, between 0.36 and 0.50 moderate, and >0.50 strong. 7 For the second objective, we calculated the SRM by dividing the mean change of the tests by the SD of the change score for the 13 participants who completed the armtraining programme. 8 Values of 0.20, 0.50, and b0.80 correspond to small, moderate, and large responsiveness respectively.…”

Purpose: To determine (1) the relationship among three common upper-limb tests for patients with chronic obstructive pulmonary disease (COPD): unsupported upper limb exercise test (UULEX), 6-minute pegboard and ring test (6PBRT), and a muscle-strength test using a hand-held dynamometer; and (2) the responsiveness of these three tests to changes after pulmonary rehabilitation that included a resistance arm-training programme. Methods: The study was a secondary analysis of a randomized controlled trial (RCT). The UULEX and the 6PBRT were used to measure peak arm exercise capacity and arm function, respectively. A handheld dynamometer was used to measure elbow and shoulder flexion force. We analyzed baseline data for all participants in the RCT, as well as baseline and post-PR data for those who completed 6-week follow-up testing. Results: 36 patients with COPD (mean forced expiratory volume in 1 second [FEV 1 ] ¼ 35% [SD 15%] predicted; age 66 [9] y) participated, of whom 13 completed an arm-training programme. The correlations among the test results ranged from 0.41 to 0.81 (p < 0.0001). Standardized response means were 1.0 for muscle force of elbow flexion, 1.2 for shoulder flexion, and 1.8 for the 6PBRT and UULEX. Conclusions: Although the three tests (UULEX, 6PBRT, and muscle-strength test using a hand-held dynamometer) are intended to measure different constructs, they were moderately to highly correlated with one another. The 6PBRT, UULEX, and muscle-strength test were demonstrated to be responsive to the resistance arm-training programme.Key Words: chronic obstructive pulmonary disease; exercise test; upper limb. RÉ SUMÉObjectif : Cette é tude visait à dé terminer (1) la relation entre trois tests courants des membres supé rieurs et la maladie pulmonaire obstructive chronique (MPOC) : test UULEX (test d'é lé vation d'un membre supé rieur), test de l'anneau (6PBRT) et é valuation de la force musculaire à l'aide d'un dynamomè tre manuel; et (2) le degré de ré activité au changement de ces trois tests aprè s une ré adaptation pulmonaire comprenant un programme d'entraînement en ré sistance des bras. Mé thode : Cette é tude é tait une analyse secondaire d'un essai clinique randomisé (ECR). Le test UULEX et le 6PBRT ont é té utilisé s pour mesurer la capacité maximale d'exercice et la fonction maximale du bras, respectivement. Un dynamomè tre manuel a é té utilisé pour mesurer la force de flexion du coude et de l'é paule. Nous avons analysé les donné es de base de tous les patients qui ont participé à l'ECR de mê me que les donné es de base et les donné es aprè s ré adaptation pulmonaire des patients qui ont participé à 6 semaines de tests de suivi. A wide variety of upper limb (UL) tests have been used in people with chronic obstructive pulmonary disease (COPD). 1 These tests assess different constructs and thus offer multiple choices to clinicians. Some commonly used UL tests are the unsupported upper limb exercise test (UULEX), 2 the 6-minute pegboard and ring 40From the:

“…None of the construct validation procedures alone offers definitive proof of validity and all suffer from logical and practical limitations [13]. However, it may be assessed by examining the ability of the scoring system to distinguish between groups of patients with expected differences in disease severity [8,9]. For example, patients colonized with Staphylococcus aureus alone were expected to have milder disease severity than those colonized with Pseudomonas aeruginosa [1, 14±16]; and those colonized with Burkholderia cepacia or multiple resistant pseudomonads (defined as the presence of pseudomonas organisms resistant to all antibiotics included in all the different classes on at least two samples of sputum close to the scoring visit) were expected to have worst disease severity compared to the other two groups [17].…”

This study reports on the evaluation of a modified Huang scoring system in adult cystic fibrosis patients for construct and longitudinal validity.Two studies were performed. In the first study, the scoring system was applied to 59 adult cystic fibrosis patients prospectively followed at the Montreal Chest Institute. The total score and all the subscores distinguished between patients with the expected mild degree of disease severity seen in patients colonized with only Staphylococcus aureus, compared to the more advanced disease severity seen in patients colonized with Pseudomonas aeruginosa or multiple resistant pseudomonads. The relationship between disease severity assessed by forced expiratory volume in one second per cent predicted and the nonpulmonary function subscores was significant and linear (for the radiological subscore, r 2 =0.694, p<0.0001) and curvilinear (for the clinical and complications subscores, r 2 =0.622, p=0.0192 and r 2 =0.508, p=0.0009 respectively). In the second study, 20 patients retrospectively recorded were added to the prospective group. There was a good association between changes in nonpulmonary function subscores and changes in spirometry over a mean follow-up period of 779204 days, at all levels of disease severity. The contribution of changes in clinical and complications subscores to the changes in total score became progressively more significant with more advanced disease severity.In conclusion, significant evidence for the construct validity of the scoring system as a discriminative instrument and for the longitudinal validity as an evaluative instrument was demonstrated. It may prove of value in assessing outcome of therapeutic interventions in clinical trials in patients with cystic fibrosis. Eur Respir J 1999; 13: 552±559.
