Abstract

There are a few standardized assessment tools in Persian language. The present study was carried out to develop a Verb Picture Naming Test and assessing its psychometric properties. In this cross-sectional study, a total of 230 verbs were selected based on their frequency, familiarity, age of acquisition, visual complexity, name agreement, image agreement, syllable length, transitivity, and compound or simple verbs. To determine content and face validity, 230 pictures of verbs were given to 15 experts, and then 180 final pictures were divided into original and parallel versions. Both versions of the test were performed on 50 healthy adults and 20 patients with Alzheimer’s diseases. Results showed that face and content validity of these versions was more than .85 and .98. Intraclass Correlation Coefficient (ICC) for total scores was equal to .98 (p < .001, 95%CI: .97–.99) and .96 (p < .001, 95%CI: .93–.98). Standard Error of Measurement (SEM) and Smallest Detectable Change (SDC) of total scores were equal to .93 and 2.66 in version1 and 1.27 and 3.12 in version 2, respectively. The two versions of Persian Verb Picture Naming Test were found to be valid and reliable, so the clinicians can use it in clinical settings.

摘要

波斯语有一些标准化的评估工具。本研究旨在开发动词图片命名测试并评估其心理测量特性。在这项横断面研究中，根据频率、熟悉度、习得年龄、视觉复杂性、名称一致性、图像一致性、音节长度、及物性以及复合或简单动词，总共选择了 230 个动词。为了确定内容和面部有效性，将 230 张动词图片提供给 15 位专家，然后将 180 张最终图片分为原始版和平行版。两种版本的测试均针对 50 名健康成人和 20 名阿尔茨海默病患者进行。结果表明，这些版本的面部和内容效度均超过 0.85 和 0.98。总分的组内相关系数 (ICC) 等于 0.98 (p  < .001, 95%CI: .97–.99) 和 0.96 ( p < .001, 95%CI: .93–.98)。测量标准误差 (SEM) 和总分的最小可检测变化 (SDC) 在版本 1 中分别等于 0.93 和 2.66，在版本 2 中分别等于 1.27 和 3.12。两个版本的波斯语动词图片命名测试被证明是有效和可靠的，因此临床医生可以在临床环境中使用它。
