%X Patients with chronic or acute cardiopulmonary conditions who came to the ED with dyspnea (Nˋ=ˋ154) completed the Multidimensional Dyspnea Profile (MDP) several times during the visit and in a follow-up visit 4 to 6ˋweeks later (nˋ=ˋ68). The MDP has 12 items with numerical ratings of intensity, unpleasantness, sensory qualities, and emotions associated with how breathing felt when participants decided to come to the ED (recall MDP) or at the time of administration (※now§ MDP). The recall MDP was administered twice in the ED and once during the follow-up visit. Principal components analysis (PCA) with varimax rotation was used to assess domain structure of the recall MDP. Internal consistency reliability was assessed with Cronbach＊s alpha. Test每retest reliability was assessed with intraclass correlation coefficients (ICCs) for absolute agreement for individual items and domains.PCA of the recall MDP was consistent with two domains (Immediate Perception, 7 items, Cronbach＊s alphaˋ=ˋ.89 to .94; Emotional Response, 5 items; Cronbach＊s alphaˋ=ˋ.81 to .85). Test每retest ICCs for the recall MDP during the ED visit ranged from .70 to .87 for individual items and were .93 and .94 for the Immediate Perception and Emotional Response domains. ICCs were much lower for the interval between the ED visit and follow-up, both for individual items (.28 to .66) and for the Immediate Perception and Emotional Response domains (.72 and .78, respectively).During an ED visit, recall MDP 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每retest reliability of recall over a 4- to 6-week interval is poor for individual items and significantly attenuated for the two domains.Recall of symptoms leading to
