The objective of this study was to identify specific cutoff scores for three commonly used embedded performance validity tests (PVTs) for a Spanish speaking population. Culturally adapted cutoff scores for embedded PVTs were established using an analog study design. In addition, the psychometric properties of these measures when applying culturally adapted scores as compared to non-adapted scores were analyzed.
Participants ( = 114) were administered three embedded PVTs (Reliable Digit Span, Phonetic Fluency Test, and Animal Semantic Fluency Test) in a randomized order. Following an analog design, control participants were instructed to perform to the best of their abilities and the analog group was instructed to simulate cognitive impairment.
In keeping with guidelines for specificity and sensitivity, the most culturally appropriate scores of ≤6, ≤27, and ≤16 were determined for the Reliable Digit Span, Phonetic Fluency Test, and the Semantic Fluency Test, respectively.
This the first study addressing culturally sensitive cutoffs for commonly used embedded validity measures using a European Spanish population. While these findings cannot be generalized to forensic or clinical populations at the present time, they support the claim that specific cutoff scores that are sensitive to cultural variables are necessary in addressing embedded validity measures of the Reliable Digit Span, Phonetic Fluency Test, and Semantic Fluency Test.
本研究旨在为西班牙语人群确定三种常用嵌入式效度量表（PVT）的特定截断分数。使用模拟研究设计为嵌入式 PVT 制定了文化适应的截断分数。此外，还分析了在应用文化适应分数与非适应分数时这些测量的心理测量特性。
参与者（n=114）以随机顺序接受三种嵌入式 PVT（可靠数字跨度、语音流畅性测试和动物语义流畅性测试）。根据模拟设计，对照组被指示尽最大能力表现，而模拟组被指示模拟认知障碍。
根据特异性和敏感性的指导原则，确定了最适合文化的分数，即可靠数字跨度、语音流畅性测试和语义流畅性测试的≤6、≤27 和≤16。
这是第一项使用欧洲西班牙语人群针对常用嵌入式效度量表的文化敏感截断值的研究。虽然这些发现目前不能推广到法医或临床人群，但它们支持这样一种说法，即需要针对可靠数字跨度、语音流畅性测试和语义流畅性测试的嵌入式效度量表的文化变量具有敏感性的特定截断分数。
