Studies suggest that individuals with aphasia present with impairments in attention. However, most research has been conducted with small sample sizes using experimental protocols that lack established psychometric properties. We examined the attention performance of 114 individuals with chronic post-stroke aphasia using a standardised, norm-referenced assessment of attention, the Conners' Continuous Performance Test-II (CPT-II; Conners, C. K. (2000). . Toronto: Multi-Health Systems Inc). Participants completed the CPT-II and the Western Aphasia Battery-Revised (WAB-R; Kertesz, A. (2007). . San Antonio, TX: PsychCorp). As a group, variable performance on selected CPT-II measures was observed. Participants demonstrated impairments on omissions (48.2%) and hit reaction time (67.5%), with 11.4% demonstrating atypically slow performance and over half of the sample (56.1%) performing atypically fast. The Confidence Index, a summary score, was also within the impaired range for the majority of participants. However, there were also measures in which a greater percentage of participants demonstrated performance within normal limits. Using the WAB-R Aphasia Quotient (AQ) as a measure of severity, there was significantly worse performance in participants with more severe (AQ < 50) compared to less severe (AQ ≥ 50) aphasia. No significant differences in attention were identified between participants with fluent versus non-fluent aphasia. The CPT-II is a feasible measure for persons with aphasia, which may assist in identifying attention performance deficits that potentially affect language.
研究表明，失语症患者存在注意力障碍。然而，大多数研究都是针对小样本量进行的，使用的实验方案缺乏已建立的心理测量特性。我们使用标准化的、基于常模的注意力评估方法——康纳斯连续操作测试第二版（CPT-II；Conners，C.K.，2000. 多伦多：多健康系统公司），对 114 名慢性中风后失语症患者的注意力表现进行了检查。参与者完成了 CPT-II 和西部失语症成套测验修订版（WAB-R；Kertesz，A.，2007. 圣安东尼奥，TX：心理公司）。观察到在某些 CPT-II 指标上，参与者的表现存在差异。参与者在遗漏（48.2%）和击中反应时间（67.5%）方面表现出障碍，11.4%的人表现出异常缓慢的反应，超过一半的样本（56.1%）表现出异常快速的反应。信心指数，一个综合分数，也在大多数参与者的受损范围内。然而，也有一些指标显示出更多的参与者表现出正常范围内的成绩。使用 WAB-R 失语症商数（AQ）作为严重程度的衡量标准，在 AQ<50 的严重程度患者中，其表现明显比 AQ≥50 的轻度患者差。在流利型和非流利型失语症患者之间，注意力没有显著差异。CPT-II 是一种适合失语症患者的可行测量方法，它可以帮助识别可能影响语言的注意力表现缺陷。
