Several studies have shown that growth hormone deficiency in adults leads to poor well-being and other clinical consequences, and that these improve when the hormone is replaced. However, the studies employed generic measures of health status that miss important aspects of the patients' experience and that have inadequate reliability and responsiveness.(More)
We describe the adaptation into Spanish of the St George's Respiratory Questionnaire (SGRQ), a self-administered questionnaire developed by Jones et al. (1991) covering three domains of health in airways disease patients: symptoms, activity and impacts. For the adaptation, the forward and back-translation method by bilinguals was used, together with(More)

BACKGROUND The American Thoracic Society recently recommended that chronic obstructive pulmonary disease be staged on the basis of the percentage of predicted FEV1. OBJECTIVE To examine 1) the relation between the american Thoracic Society system for staging chronic obstructive pulmonary disease and health-related quality of life and 2) the effect of(More)
BACKGROUND Perceived health status measurements reference values an important information source for health services research. Population-based norms have been proposed to increase their interpretability. In this paper, we have obtained the norms of the Spanish version of the SF-36 Health Survey and have compared them with US norms the questionnaire. (More)
BACKGROUND In spite of a well-established development of instruments, difficulty in interpreting health related quality of life scores may limit its use in clinical practice. OBJECTIVE To develop generalizable interpretation aids for a measure of perceived functional visual status, the VF-14 index. DESIGN Item Response Theory (Rasch analysis) was used(More)
AIMS Health-related quality of life assessment may be useful for understanding the variability in functioning of patients with a similar level of clinical impairment. We assessed the reliability, validity and responsiveness to clinical change of a reduced version of the Duke Activity Status Index (DASI) in chronic coronary patients. METHODS AND RESULTS(More)
