This paper describes preliminary studies on a screening test for aphasia which takes 3-10 minutes to complete and which is suitable for use by general practitioners, junior medical staff and other non-specialists. Data are presented to show that it is a reliable, valid assessment. Using cut-off values derived from normal people, the test is sensitive, but its specificity is limited by such associated factors as hemianopia. Using cut-off values derived from patients known to have aphasia, its specificity is improved. An abnormal result needs to be interpreted in the light of all available clinical information. The test should help identify patients with linguistic disturbance.
本文描述了一项针对失语症的筛查测试的初步研究，该测试需3至10分钟完成，适合全科医生、初级医务人员及其他非专科医生使用。文中给出的数据表明这是一项可靠、有效的评估。采用从正常人得出的临界值时，该测试具有敏感性，但其特异性受到偏盲等相关因素的限制。采用从已知患有失语症的患者得出的临界值时，其特异性得到提高。异常结果需要根据所有可用的临床信息进行解读。该测试应有助于识别有语言障碍的患者。
