The purpose of this study was to validate a 3-factor measurement model of dyspnea sensory quality (WORK-EFFORT, TIGHTNESS, SMOTHERING-AIR HUNGER) originally derived in patients with exacerbated chronic obstructive pulmonary disease.
In this validation study, adult patients with heart failure were enrolled after hospital admission (median hospital day 1) and asked to rate the intensity of dyspnea sensory quality descriptors on the day of enrollment (study day 1; N = 119) and in a recall version for the day of admission (study day 0; n = 97).
Confirmatory factor analysis demonstrated good model fit for both days. Cronbach's α for each factor was greater than .87 for both study days.
This is the first study to validate a previously specified measurement model of dyspnea sensory quality in an independent sample. Results indicate that measurement of dyspnea sensory quality in exacerbated cardiopulmonary disease does not necessarily require disease-specific questionnaires.
本研究旨在验证呼吸困难感知质量的三因素测量模型(工作努力、紧绷感、窒息感),该模型最初是在慢性阻塞性肺疾病加重的患者中得出的。
在这项验证性研究中,在住院后(住院第 1 天)招募了成年心力衰竭患者,并要求他们在入组当天(研究第 1 天;N=119)和回忆入院当天(研究第 0 天;n=97)对呼吸困难感知质量描述符的强度进行评分。
验证性因子分析表明,两天的模型拟合度均较好。对于两天的数据,每个因子的克朗巴赫 α 均大于 0.87。
这是首次在独立样本中验证呼吸困难感知质量的预先指定测量模型。结果表明,在加重的心肺疾病中测量呼吸困难感知质量不一定需要特定疾病的问卷。
