Test-retest reliability of multidimensional dyspnea profile recall ratings in the emergency department: a prospective, longitudinal study Full Text
BMC Emergency Medicine, 05/31/2012
Parshall MB et al. – During an emergency department (ED) visit, recall Multidimensional Dyspnea Profile ratings of dyspnea at the time participants decided to seek care in the ED are reliable and sufficiently stable, both for individual items and the two domains, that a time lag between arrival and questionnaire administration does not critically affect recall of perceptual and emotional characteristics immediately prior to the visit. However, test–retest reliability of recall over a 4– to 6–week interval is poor for individual items and significantly attenuated for the two domains.
