Abstract

Background: Detecting impaired naming capacity contributes to the detection of mild (MildND) and major (MajorND) neurocognitive disorder due to Alzheimer's disease (AD). The Test for Finding Word retrieval deficits (WoFi) is a new, 50-item, auditory stimuli-based instrument.

Objective: The study aimed to adapt WoFi to the Greek language, to develop a short version of WoFi (WoFi-brief), to compare the item frequency and the utility of both instruments with the naming subtest of the widely used Addenbrooke's cognitive examination III (ACEIIINaming) in detecting MildND and MajorND due to AD.

Methods: This cross-sectional, validation study included 99 individuals without neurocognitive disorder, as well as 114 and 49 patients with MildND and MajorND due to AD, respectively. The analyses included categorical principal components analysis using Cramer's V, assessment of the frequency of test items based on corpora of television subtitles, comparison analyses, Kernel Fisher discriminant analysis models, proportional odds logistic regression (POLR) models and stratified repeated random subsampling used to recursive partitioning to training and validation set (70/30 ratio).

Results: WoFi and WoFi-brief, which consists of 16 items, have comparable item frequency and utility and outperform ACEIIINaming. According to the results of the discriminant analysis, the misclassification error was 30.9%, 33.6% and 42.4% for WoFi, WoFi-brief and ACEIIINaming, respectively. In the validation regression model including WoFi the mean misclassification error was 33%, while in those including WoFi-brief and ACEIIINaming it was 31% and 34%, respectively.

Conclusions: WoFi and WoFi-brief are more effective in detecting MildND and MajorND due to AD than ACEIIINaming.

在自然临床环境中验证发现单词检索缺陷测试（WoFi）在检测阿尔茨海默病方面的有效性。

背景：检测命名能力受损有助于发现阿尔茨海默病（AD）导致的轻度（MildND）和重度（MajorND）神经认知障碍。发现词语检索缺陷测试（WoFi）是一种基于听觉刺激的新工具，共有 50 个项目：研究旨在将 WoFi 改编为希腊语，开发 WoFi 的简短版本（WoFi-brief），比较这两种工具与广泛使用的 Addenbrooke's cognitive examination III（ACEIIINaming）命名子测试在检测 AD 引起的轻度ND 和重度ND 方面的项目频率和实用性：这项横断面验证研究包括 99 名无神经认知障碍的患者，以及分别为 114 名和 49 名轻度和重度 ADND 患者。分析包括使用 Cramer's V 进行的分类主成分分析、基于电视字幕语料库的测试项目频率评估、对比分析、核费雪判别分析模型、比例几率逻辑回归（POLR）模型和分层重复随机子采样，并对训练集和验证集进行递归分区（70/30 比例）：由 16 个条目组成的 WoFi 和 WoFi-brief 的条目频率和效用相当，优于 ACEIIINaming。根据判别分析结果，WoFi、WoFi-brief 和 ACEIIINaming 的误分类误差分别为 30.9%、33.6% 和 42.4%。在包括 WoFi 的验证回归模型中，平均误分类误差为 33%，而在包括 WoFi-brief 和 ACEIIINaming 的模型中，误分类误差分别为 31% 和 34%：与 ACEIIINaming 相比，WoFi 和 WoFi-brief 能更有效地检测出 AD 引起的轻度ND 和重度ND。

期刊介绍： The European Journal of Ageing: Social, Behavioural and Health Perspectives is an interdisciplinary journal devoted to the understanding of ageing in European societies and the world over. EJA publishes original articles on the social, behavioral and population health aspects of ageing and encourages an integrated approach between these aspects. Emphasis is put on publishing empirical research (including meta-analyses), but conceptual papers (including narrative reviews) and methodological contributions will also be considered. EJA welcomes expert opinions on critical issues in ageing. By stimulating communication between researchers and those using research findings, it aims to contribute to the formulation of better policies and the development of better practice in serving older adults. To further specify, with the term ''social'' is meant the full scope of social science of ageing related research from the micro to the macro level of analysis. With the term ''behavioural'' the full scope of psychological ageing research including life span approaches based on a range of age groups from young to old is envisaged. The term ''population health-related'' denotes social-epidemiological and public health oriented research including research on functional health in the widest possible sense.
