COPD (With - Without Rehabilitation) Clinical Trial
Official title:
Development of a New Tool for Dyspnea Measurement (DYSLIM for Dyspnea Limitation) in Chronic Respiratory Diseases
The purpose of this study is the psychometric validation of a self-administered dyspnea questionnaire, usable in clinical practice in order to assess dyspnea and its impact on patients with chronic respiratory diseases.
Dyspnea is a cardinal Respiratory symptom.
According to the ATS dyspnea is the term used to characterize a subjective experience of
breathing discomfort, covering qualitatively distinct sensations of varying intensity.
The subjective nature of dyspnea and the high complexity of its determinants explain the
often moderate correlations obtained with physiological data. Dyspnea must therefore be
measured specifically.
The aim of this study is the cross-sectional and longitudinal psychometric validation of a
self-administered dyspnea questionnaire (assessing the impact of dyspnea on activities
restriction), usable in clinical practice in order to assess dyspnea and its alterations in
adult patients with chronic respiratory diseases.
(COPD, diffuse interstitial lung diseases, Pulmonary arterial hypertension, Cystic fibrosis)
Like any psychometric instrument, an efficient evaluation of dyspnea scale should ideally
satisfy all the following required features: evaluative, discriminant, good reproducibility,
and high sensitivity to change.
The desired features apart from content validity are reproducibility and especially a high
sensitivity to change, particularly following pulmonary rehabilitation.
Thus, this questionnaire should precisely enable to assess the benefit of rehabilitation and
it's sustainment in maintenance phase.
