目的:我们使用英语适应语言筛查测试(LASTen)描述急性中风语言筛查的招募可行性,最初是用法语开发的。我们还阐明了LASTen在有和没有失语症的患者中的初步测量特性。
方法:前瞻性资格跟踪,招募,使用两种平行形式筛查失语症,LASTEN-A和LASTEN-B
方法:三级医院的神经血管单元和短暂性脑缺血发作和轻微中风单元。
方法:超急性至亚急性卒中患者(N=12)。
方法:不适用。
方法:符合条件的患者人数和招募可行性,根据失语症状态分组的12名患者的两种LASTen版本(每个15分)的个人性能指标,和两种并行形式的可靠性。
结果:有25名合格的卒中患者超过1个月。所有12名招募的患者都同意进行测试。患者的年龄从29岁到85岁,5是女人。三名患者出现脑出血,6人出现失语症(轻度至重度)。有和没有失语症的患者的LASTen评分中位数为10(四分位距,8)和15(四分位距,0),分别。五名患者在涉及1分差异的版本中得分不一致。一位失语症患者有5分的差异,展示对第二个版本的改进。平行形式可靠性的Pearson相关系数为0.95。
结论:我们的研究证实了LASTen似乎按照设计发挥作用。失语症患者存在评分异质性,无失语症患者存在期望的上限效应,除了出色的并行形式可靠性。这些发现为急性中风患者的大规模诊断准确性试验提供了动力。
OBJECTIVE: We describe recruitment feasibility for language screening in acute stroke using the English adaptation the Language Screening Test (LASTen), originally developed in French. We also elucidate preliminary measurement properties of LASTen in patients with and without aphasia.
METHODS: Prospective eligibility tracking, recruitment, and screening for aphasia using the 2 parallel forms, LASTen-A and LASTen-B.
METHODS: The Neurovascular Unit and the Transient Ischemic Attack and Minor Stroke Unit of a tertiary care hospital.
METHODS: Stroke patients (N=12) with hyperacute to subacute stroke.
METHODS: Not applicable.
METHODS: Numbers of eligible patients and recruitment viability, individual performance indicators for both LASTen versions (15 points each) in 12 patients grouped by aphasia status, and reliability of the 2 parallel forms.
RESULTS: There were 25 eligible stroke patients over 1 month. All 12 recruited patients consented to testing. The patients ranged in age from 29 to 85 years, and 5 were women. Three patients had intracerebral hemorrhage, and 6 had aphasia (mild to severe). The median LASTen scores in patients with and without aphasia were 10 (interquartile range, 8) and 15 (interquartile range, 0), respectively. Five patients had discrepant scores across versions involving a 1-point difference. One patient with aphasia had a 5-point difference, demonstrating improvement on the second version. The Pearson correlation coefficient was 0.95 for parallel form reliability.
CONCLUSIONS: Our study confirmed that LASTen appears to function as designed. There was score heterogeneity for patients with aphasia and desired ceiling effects for those without aphasia, alongside excellent parallel form reliability. The findings provide the impetus for a large-scale diagnostic accuracy trial in acute stroke patients.
