[Health-related quality of life measurement: a critical reading guide].
BACKGROUND
Quality of life is rarely assessed in the pulmonary function laboratory. Quality of life, or at least some of its domains, should be directly measured.


BACKGROUND
Quality-of-life questionnaires developed according to established protocols can be very useful in clinical practice. In clinical studies, the choice of a questionnaire depends on its function (evaluative or discriminative) which should be supported by its measurement properties (validity, reliability, responsiveness).


CONCLUSIONS
The methodology of critical appraisal of an article about quality of life proposed in this reading guide are in keeping with the principles of evidence-based medicine.
