ABSTRACT

Background

The Comprehensive Aphasia Test (CAT) has recently been adapted to a number of languages – including Hungarian – by an international network of multidisciplinary aphasia researchers, the Collaboration of Aphasia Trialists. In Hungarian, to date, there is no standardised test to assess people with aphasia (PWA).

Aims

The aim of this paper was to evaluate psychometric properties of the Hungarian adaptation of the CAT (CAT-H) by assessing internal consistency, reliability, and validity of the test. In addition, we reiterate main challenges of the adaptation – so far only published in Hungarian – and present the main characteristics of the CAT-H.

Methods & Procedures

One hundred PWA, mostly with unilateral, left hemisphere stroke, and 34 healthy control participants completed the CAT-H which consists of two parts: A Cognitive Screening Test (CST) and a Language Battery (LB). Our analysis included (1) comparison of performance between PWA and control participants in all subtests; (2) assessment of inter-rater and test–retest reliability in a small group of PWA (N = 10 and N = 9, respectively) using intra-class correlation coefficients (ICCs); (3) assessment of construct validity by performing principal component analysis (PCA) on subtests of the CST and subtests of the LB in the aphasia group; (4) assessment of concurrent validity by calculating Spearman rank correlation coefficients between subtests of the CAT-H and subtests of the Western Aphasia Battery (WAB; N = 59) and the Test for the Reception of Grammar-Hungarian (TROG-H; N = 35).

Outcomes & Results

Our results show that the CAT-H has good-to-excellent psychometric properties. It is able to differentiate between aphasic and non-aphasic performance and it demonstrates strong internal consistency. Moderate to high ICCs suggest good-to-excellent inter-rater and test–retest reliability for most subtests of the LB. Consistent with the English CAT, the PCA identified one component in the CST and three components in the LB. High correlations between subtests of the CAT-H and subtests of the WAB and the TROG-H suggest satisfying concurrent validity for the CAT-H.

Conclusions

Comparable psychometric properties of the CAT-H and the original version of the CAT suggest that the Hungarian language and cultural adaptation was successful. We believe that the CAT-H will be a unique resource for rehabilitation professionals and aphasia researchers in aphasia assessment in Hungary. In addition, together with adaptations in other languages, it may provide a unique tool for cross-linguistic aphasia assessment.

综合失语症测试-匈牙利语：适应和心理测量特性

摘要

背景

综合性失语症测试 (CAT) 最近已被多学科失语症研究人员国际网络（失语症试验者协作组织）改编为多种语言，包括匈牙利语。迄今为止，在匈牙利，还没有用于评估失语症 (PWA) 患者的标准化测试。

目标

本文的目的是通过评估测试的内部一致性、可靠性和有效性来评估匈牙利语适应 CAT (CAT-H) 的心理测量特性。此外，我们重申了改编的主要挑战——迄今为止仅以匈牙利语出版——并介绍了 CAT-H 的主要特征。

方法和程序

一百名 PWA（主要是单侧左半球中风）和 34 名健康对照参与者完成了由两部分组成的 CAT-H：认知筛查测试 (CST) 和语言电池 (LB)。我们的分析包括 (1) PWA 和对照组参与者在所有子测试中的表现比较；(2) 评估一小组 PWA 中的评分者间和重测信度（N = 10 和N= 9，分别）使用类内相关系数（ICC）；(3) 通过对失语组的 CST 分测验和 LB 分测验进行主成分分析 (PCA) 来评估结构效度；(4) 通过计算 CAT-H 的子测试和西方失语症电池 (WAB; N = 59) 的子测试和匈牙利语法接收测试 (TROG-H; N )之间的 Spearman 等级相关系数来评估同时效度= 35)。

结果和结果

我们的结果表明，CAT-H 具有从良好到优秀的心理测量特性。它能够区分失语和非失语表现，并表现出很强的内部一致性。中等到高的 ICC 表明 LB 的大多数子测验具有良好到优秀的评分者间和重测信度。与英语 CAT 一致，PCA 确定了 CST 中的一个组成部分和 LB 中的三个组成部分。CAT-H 的子测试与 WAB 和 TROG-H 的子测试之间的高度相关性表明满足 CAT-H 的同时效度。

结论

CAT-H 和原始版本的 CAT 的可比心理测量特性表明匈牙利语言和文化适应是成功的。我们相信 CAT-H 将成为匈牙利失语症评估康复专业人员和失语症研究人员的独特资源。此外，与其他语言的改编一起，它可能为跨语言失语症评估提供独特的工具。
