Clinical validation of the Spanish version of the Mississippi Aphasia Screening Test (MASTsp) as a screening test for language disorders in patients who have suffered a stroke.
A total of 29 patients who had suffered a stroke and had aphasia after a left hemispheric lesion were evaluated with the MASTsp, the Boston Diagnostic Aphasia Examination and the Token Test at baseline and after six months of rehabilitation. Two expert speech-therapists evaluated twelve aphasic patients to determine the inter-observer reliability. This sample was assessed twice in the same week to analyse the reproducibility of the test (test-retest reliability). Aphasic patients were compared with a matched sample of non-aphasic patients with vascular lesions in the right hemisphere (n =29) and a group of healthy subjects (n=60) stratified by age and educational level.
The MASTsp showed a good convergent validity, interobserver validity, test-retest reliability and a moderate sensitivity to detect changes over time. A diagnostic cut-off <90 on the MASTsp total test score is proposed.
The MASTsp is a valid tool for the detection and monitoring of language problems in patients with stroke.
对西班牙语版密西西比失语症筛查测试（MASTsp）作为中风患者语言障碍筛查测试进行临床验证。
共有29例中风后左侧半球病变并发失语症的患者在基线期和康复6个月后接受了MASTsp、波士顿诊断性失语症检查及代币测试评估。两名专业言语治疗师对12例失语症患者进行评估以确定观察者间信度。该样本在同一周内接受两次评估以分析测试的可重复性（重测信度）。将失语症患者与一组年龄和教育水平匹配的右侧半球血管病变非失语症患者样本（n = 29）及一组健康受试者（n = 60）进行比较。
MASTsp显示出良好的收敛效度、观察者间效度、重测信度以及对随时间变化的中等敏感度。建议MASTsp总测试分数的诊断临界值<90。
MASTsp是检测和监测中风患者语言问题的有效工具。
