Abstract

The Toulouse-Piéron Cancelation Test (TP) is a classic psychometric tool for the assessment of selective/sustained attention, processing speed and visuo-perceptual abilities. It is commonly used in neurological disorders such as epilepsy, multiple sclerosis or Alzheimer’s disease. It encompasses two main indexes: Work-Efficiency (WE) and Dispersion-Index (DI). The aim of this study is to provide normative scores for the TP in a sample of Portuguese healthy adults. The TP was administered to a convenience sample of 357 cognitively-dwelling subjects aged between [45 and 86] years old, following a standard assessment protocol. The normative scores were adjusted for age and education. Education was the main predictor of TP-WE (R² = .310), whereas the influence of age on this score was lower (R² = .191). These two variables explained 50.1% of the variance of the results. Regarding TP-DI, education was also the main predictor of the results (R² = .039), whereas age was responsible for R² = .011 and together, they explained 5% of the variance of TP-DI. TP performances are strongly influenced by age and education. This is the first study focused on the establishment of normative data after the age of 45 in the Portuguese population, allowing a reliable assessment in both clinical and research contexts.

摘要

图卢兹-皮埃龙取消测试 (TP) 是一种经典的心理测量工具，用于评估选择性/持续注意力、处理速度和视觉感知能力。它常用于神经系统疾病，如癫痫、多发性硬化症或阿尔茨海默病。它包括两个主要指标：工作效率（WE）和分散指数（DI）。本研究的目的是为葡萄牙健康成年人样本提供 TP 的规范分数。按照标准评估方案，对 357 名年龄在 [45 至 86] 岁之间的认知居留受试者的便利样本进行了 TP。标准分数根据年龄和教育进行了调整。教育是 TP-WE 的主要预测因素 (R ² = .310)，而年龄对该分数的影响较低 (R ²=.191）。这两个变量解释了 50.1% 的结果方差。关于 TP-DI，教育也是结果的主要预测因素 (R ² = .039)，而年龄是 R ² = .011 的原因，它们共同解释了 TP-DI 的 5% 方差。TP 表现受年龄和教育程度的强烈影响。这是第一项侧重于在葡萄牙人口中建立 45 岁后规范数据的研究，允许在临床和研究环境中进行可靠的评估。
