Abstract

The Hooper Visual Organization Test (HVOT) is used to assess visual organization and visual synthesis. Psychometric studies reveal cultural biases and associations between demographic variables and test performance capable of compromising the test’s clinical utility. The present study aimed to adapt the HVOT, explore the psychometric properties of this test, and develop regression-based norms for the Venezuelan population. Using a cross-sectional design, the HVOT was administered to a stratified sample of 351 healthy adults (20–85 years of age and 0–23 years of education) from the Metropolitan Area of Caracas. The results revealed good levels of internal consistency and reliability. Confirmatory Factor Analysis suggests that the HVOT is unidimensional. Item difficulty, types and rate of errors and inappropriateness of some items indicated a potential cultural bias in our Venezuelan sample. Spearman’s Correlation and Wilcoxon Rank test analysis (p<.001) showed a significant association between HVOT total score and age, education, and gender, but not with socioeconomic status. We present regression-norms stratified by age, years of education, and gender. Cultural biases were noted, which highlights the need for a revision of items in terms of inclusion, scoring, and order of presentation. Future studies of concurrent and predictive validity are needed.

摘要

Hooper 视觉组织测试 (HVOT) 用于评估视觉组织和视觉合成。心理测量学研究揭示了人口统计学变量与测试表现之间的文化偏见和关联，从而影响了测试的临床效用。本研究旨在调整 HVOT，探索该测试的心理测量特性，并为委内瑞拉人口制定基于回归的规范。使用横断面设计，HVOT 对来自加拉加斯都会区的 351 名健康成年人（20-85 岁和 0-23 岁教育）的分层样本进行管理。结果显示了良好的内部一致性和可靠性水平。验证性因子分析表明 HVOT 是一维的。项目难度，错误的类型和比率以及某些项目的不当之处表明我们的委内瑞拉样本中存在潜在的文化偏见。Spearman 相关性和 Wilcoxon 秩检验分析 (p <.001) 显示 HVOT 总分与年龄、教育和性别之间存在显着关联，但与社会经济地位无关。我们提出了按年龄、受教育年限和性别分层的回归规范。注意到文化偏见，这突出了在包含、评分和呈现顺序方面对项目进行修订的必要性。未来需要对并发有效性和预测有效性进行研究。
