Anomia is usually assessed using picture-naming tests. While many tests evaluate anomia for nouns, very few tests have been specifically designed for verb anomia. This article presents the DVAQ-30, a new naming test for detecting verb anomia in adults and elderly people.
The article describes three studies. Study 1 focused on the DVAQ-30 development phase. In Study 2, healthy participants and individuals with post-stroke aphasia, mild cognitive impairment, Alzheimer's disease, or primary progressive aphasia were assessed using the DVAQ-30 to establish its convergent and discriminant validity, test-retest reliability, and internal consistency. In Study 3, a group of adults and elderly Quebec French-speaking adults were assessed to obtain normative data.
The DVAQ-30 had good convergent validity and distinguished the performance of healthy participants from that of participants with pathological conditions. The test also had good internal consistency, and the test-retest analysis showed that the scores had good temporal stability. Furthermore, normative data were collected on the performance of 244 participants aged 50 years old and over.
The DVAQ-30 fills an important gap and has the potential to help clinicians and researchers better detect verb anomia associated with pathological aging and post-stroke aphasia.
命名障碍通常通过图片命名测试进行评估。虽然有许多测试评估名词的命名障碍，但专门用于动词命名障碍的测试却很少。本文介绍了 DVAQ-30，这是一种用于检测成人和老年人动词命名障碍的新命名测试。
本文描述了三项研究。研究 1 侧重于 DVAQ-30 的开发阶段。在研究 2 中，使用 DVAQ-30 对健康参与者和患有卒中后失语症、轻度认知障碍、阿尔茨海默病或原发性进行性失语症的个体进行评估，以确定其收敛效度和判别效度、重测信度和内部一致性。在研究 3 中，对一组成年和老年魁北克法语使用者进行评估，以获得常模数据。
DVAQ-30 具有良好的收敛效度，可以区分健康参与者和有病理状况的参与者的表现。该测试还具有良好的内部一致性，重测分析表明分数具有良好的时间稳定性。此外，还收集了 244 名 50 岁及以上参与者的表现的常模数据。
DVAQ-30 填补了一个重要的空白，有潜力帮助临床医生和研究人员更好地检测与病理性衰老和卒中后失语症相关的动词命名障碍。
