本研究的目的是评估急诊科（ED）加重慢性阻塞性肺疾病（COPD）患者呼吸困难感觉质量描述符评分的信度、内容效度和因素结构。在急诊科就诊期间，104名COPD患者对16种呼吸困难感觉质量描述符的强度进行了评分（数值评分为0-10），与他们决定来急诊科就诊时和就诊前一周的感受有关。15个描述符的内容效度得到支持。决策评分的因子分析得到7个描述符和3个因子（α= 0.88； 74%共同方差）：窒息/窒息/渴望空气（α= 0.87）；努力/工作(α= .87点);和Tight/Constricted （α=.74）。结果表明，感觉质量描述符的强度可以可靠地测量COPD患者在COPD加重期间。描述符的初始描述符列表可以在保留令人满意的心理测量性质的同时减少一半以上。©2002 Wiley期刊公司《中华卫生杂志》，2002
The purpose of this study was to evaluate the reliability, content validity, and factor structure of dyspnea sensory quality descriptor ratings in emergency department (ED) patients with exacerbated chronic obstructive pulmonary disease (COPD). During an ED visit 104 patients with COPD rated the intensity of 16 dyspnea sensory quality descriptors (numerical ratings of 0–10) in relation to how they felt when they decided to come to the ED (Decision) and 1 week before the visit. Content validity of 15 descriptors was supported. Factor analysis of Decision ratings resulted in seven descriptors and three factors (α=.88; 74% common variance): Smothering/Suffocating/Hunger for air (α=.87); Effort/Work (α=.87); and Tight/Constricted (α=.74). Results indicate that the intensity of sensory quality descriptors can be measured reliably in COPD patients during an exacerbation of COPD. The initial descriptor list of descriptors could be cut by more than half while retaining satisfactory psychometric properties. © 2002 Wiley Periodicals, Inc. Res Nurs Health 25:331–344, 2002
