本探索性研究旨在检验脑卒中患者吞咽障碍的相关因素和特征的信度和效度。研究样本包括：(1)12名护理专家，(2)52名神经内科病房护士，(3)107例脑卒中患者，分为BDST （Burks吞咽困难筛查试验）阳性组（n = 51）和BDST阴性组（n = 56）。收集数据并根据专家效度、诊断内容效度、结构效度和区分效度对数据进行验证。结果显示，17个相关因素和12个定义特征的DCV得分均大于0.5。Cronbach alpha系数为0.89，证明了12个定义特征的内部一致性。经因子分析，从12个定义特征中提取2个因子；这两项分别是“言语障碍患者吞咽风险高”和“吞咽无效”。通过logistic回归确定了5个主要的定义特征，即食物的口袋，急性误吸的迹象，喉咙后部灼烧或发痒，吐食物或食物从口中漏出，虚弱或沙哑的咳嗽。本研究结果提示，17个相关因素和12个界定特征对脑卒中患者吞咽障碍的诊断是可靠和有效的。
This exploratory study was conducted to examine the reliability and validity of related factors and defining characteristics of impaired swallowing for stroke patients. Sample of the study included (1) 12 nursing experts, (2) 52 nurses who work in neurological wards, and (3) 107 stroke patients who were divided into a BDST (Burks Dysphagia Screening Test)-positive group (n = 51) and a BDST-negative group (n = 56). Data were collected and validated based on expert validity, diagnostic content validity (DCV), construct validity, and discriminate validity. Results showed that the DCV scores of 17 related factors and 12 defining characteristics were all greater than 0.5. The internal consistency of the 12 defining characteristics was demonstrated by a Cronbach alpha coefficient of 0.89. Two factors were extracted from the 12 defining characteristics after factor analysis; these were "high risk of aspiration with speech disorder" and "ineffectiveness of swallowing". Five major defining characteristics, i.e. pocketing of food, signs of acute aspiration, burning or tickling at the back of the throat, spitting food or food leaking from the mouth, and weak or hoarse cough, were determined by logistic regression. The findings of this study suggest that the 17 related factors and 12 defining characteristics are reliable and valid in diagnosing the problem of impaired swallowing for stroke patients.
