ABSTRACT

The Wisconsin Card Sorting Test (WCST) is a widely used neuropsychological assessment of executive functioning. The aim of this study was to provide norm values and analyze the psychometric properties of WCST in healthy Argentinian adults aged from 18 to 89 years old (N = 235). Descriptive statistics are reported as means, standard deviations and percentiles, with the effects of age, education and gender being investigated by ANOVA, and with the effect sizes being calculated. The psychometrics were studied using the WCST structure, reliability, convergent validity, and discriminant validity, and WCST norms adjusted for age and educational level are proposed. This instrument is a reliable and valid tool for the assessment of executive functions. However, as the age- and educational-related effects were demonstrated, these characteristics need to be considered before interpreting WCST scores. Regarding gender, no differences were found. Our results expand the geographical and sociocultural applicability of WCST.

摘要

威斯康星卡片分类测试 (WCST) 是一种广泛使用的执行功能神经心理学评估。本研究的目的是提供常态值并分析 WCST 在 18 至 89 岁的健康阿根廷成年人中的心理测量特性（N= 235）。描述性统计以平均值、标准差和百分位数的形式报告，年龄、教育和性别的影响由方差分析调查，并计算影响大小。使用 WCST 结构、信度、收敛效度和判别效度对心理测量学进行了研究，并提出了根据年龄和教育水平调整的 WCST 规范。该工具是评估执行功能的可靠且有效的工具。然而，随着年龄和教育相关的影响得到证实，在解释 WCST 分数之前需要考虑这些特征。关于性别，没有发现差异。我们的结果扩展了 WCST 的地理和社会文化适用性。
