| Popis: | To assess the validity and reliability of the chronic respiratory questionnaire (CRQ) in the measurement of HRQL in the Colombian population with COPD. A cross-sectional study was conducted with a sample of 200 patients diagnosed with COPD according to GOLD criteria. Convergence validity was evaluated by correlating the questionnaire results with other clinical variables such as exercise tolerance, forced expiratory volume at the first second (FEV1), and depression levels. HRQL measured through the CRQ correlated significantly with the 6-min walk test (r = 0.34), just as the dimensions fatigue (r = 0.37) and dyspnoea correlated with the FEV1 test (r = 0.21) and the dimensions emotional function and disease management with depression levels (r = −0.79). The Generalized Structured Component Analysis (GSCA) with the prespecified model is showed, and the total variance explained by the items in the model was 61.5 % (FIT = 0.615), unweighted least squares (GFI = 0.998), and standardised root mean square (SRMR = 0.084), indicating that the model fits adequately. The CRQ presents evidence of adequate validity and reliability in the Colombian population. Its use is recommended to measure HRQL in patients with COPD, although future validations will be needed to identify the property of sensitivity to change. |
