Are volunteered and endorsed descriptors of recalled breathlessness consistent with descriptors of exercise-induced breathlessness? Are volunteered and endorsed descriptors of exercise-induced breathlessness consistent?
Within-participant, repeated measures, experimental study.
57 people with symptomatic chronic respiratory disease aged 71 years.
There were three conditions. The first was recalled breathlessness. Two conditions of exercise-induced breathlessness were created by getting the participants to undertake the 6-min Walk Test twice (breathlessness 1 and 2).
Descriptors of breathlessness were volunteered (where participants' used their own words) or endorsed (from a pre-existing list of 15 breathlessness statements).
Emotive descriptors made up 65% of recalled descriptors compared with 11% of exercise-induced descriptors, whereas physical descriptors made up 35% of recalled descriptors compared with 89% of exercise-induced descriptors. Of the 237 potential language pairs volunteered to describe recalled and exercise-induced breathlessness 1, only 27 (11%) were identical whereas of the 171 potential language pairs endorsed as describing recalled and exercise-induced breathlessness 1, 66 (39%) were identical. Of the 175 potential language pairs of descriptors volunteered to describe exercise-induced breathlessness 1 and 2, 72 (41%) were identical whereas of the 153 potential language pairs endorsed as describing exercise-induced breathlessness 1 and 2, 71 (46%) were identical.
The language used to describe exercise-induced breathlessness immediately after two walking challenges was similar. However, descriptions of recalled breathlessness did not consistently match descriptions of exercise-induced breathlessness, which may reflect the different contexts under which breathlessness was recalled and induced.
回忆起的呼吸急促的自发描述和认可描述与运动诱发的呼吸急促的描述是否一致？运动诱发的呼吸急促的自发描述和认可描述是否一致？
参与者内重复测量实验研究。
57名71岁有症状的慢性呼吸道疾病患者。
有三种情况。第一种是回忆起的呼吸急促。通过让参与者进行两次6分钟步行测试（呼吸急促1和呼吸急促2）创造出两种运动诱发呼吸急促的情况。
呼吸急促的描述是自发给出的（参与者用自己的话）或认可的（从预先存在的15条呼吸急促陈述列表中选择）。
与运动诱发描述中的11%相比，情感描述占回忆描述的65%，而身体描述在回忆描述中占35%，在运动诱发描述中占89%。在自发描述回忆起的和运动诱发的呼吸急促1的237对潜在语言对中，只有27对（11%）是相同的；而在被认可为描述回忆起的和运动诱发的呼吸急促1的171对潜在语言对中，66对（39%）是相同的。在自发描述运动诱发的呼吸急促1和2的175对潜在语言对中，72对（41%）是相同的；而在被认可为描述运动诱发的呼吸急促1和2的153对潜在语言对中，71对（46%）是相同的。
在两次步行挑战后立即用于描述运动诱发的呼吸急促的语言是相似的。然而，回忆起的呼吸急促的描述与运动诱发的呼吸急促的描述并不一致，这可能反映了回忆起的和诱发的呼吸急促所处的不同背景。
