Questionnaires could facilitate the guidance of patient-tailored disease management by exploring which aspects of health status are problematic and which aspects are not. Health status consists of four main domains physiological functioning symptoms functional impairment and quality of life and at least sixteen sub-domains. A prerequisite for patient-tailored treatment is a detailed assessment of all these sub-domains. Most questionnaires developed to measure health status consist of one or a few subscales and measure merely some aspects of health status. The question then rises which aspects of health status are measured by these instruments and which aspects are not covered. As it is one of the most frequently used questionnaires in COPD we evaluated which aspects of health status are measured and which aspects are not measured by the St George s Respiratory Questionnaire SGRQ . Methods One hundred and forty-six outpatients with COPD participated. Correlations were calculated between the three sections of the SGRQ and ten sub-domains of the Nijmegen Integral Assessment Framework covering Symptoms Functional Impairment and Quality of Life. As the SGRQ was not expected to measure physiological functioning we did not include this main domain in the statistical analyses. Pearson s r was used as criterion for conceptual similarity. Results The SGRQ sections Symptoms and Total showed conceptual similarity with the sub-domain Subjective Symptoms main
