ABSTRACT

To examine the potential of the Five-Variable Psychiatric Screener (V-5) to serve as an embedded symptom validity test (SVT). In Study 1, 43 undergraduate students were randomly assigned to a control or an experimental malingering condition. In Study 2, 150 undergraduate students were recruited to examine the cognitive and emotional sequelae of self-reported trauma history. The classification accuracy of the V-5 was computed against the Inventory of Problems (IOP-29), a free-standing SVT. In Study 1, the V-5 was a poor predictor of experimental malingering status, but produced a high overall classification against the IOP-29. In Study 2, the V-5 was a stronger predictor of IOP-29 than self-reported trauma history. Results provide preliminary support for the utility of the V-5 as an embedded SVT. Given the combination of growing awareness of the need to determine the credibility of subjective symptom report using objective empirical methods and systemic pressures to abbreviate assessment, research on SVTs within rapid assessment instruments can provide practical psychometric solutions to this dilemma.

摘要

检查五变量精神病筛查仪 (V-5) 作为嵌入式症状有效性测试 (SVT) 的潜力。在研究 1 中，43 名本科生被随机分配到对照组或实验性装病组。在研究 2 中，招募了 150 名本科生来检查自我报告的创伤史的认知和情感后遗症。V-5 的分类精度是根据问题清单 (IOP-29) 计算的，这是一个独立的 SVT。在研究 1 中，V-5 对实验性装病状态的预测效果不佳，但对 IOP-29 产生了较高的总体分类。在研究 2 中，V-5 比自我报告的创伤史更能预测 IOP-29。结果为 V-5 作为嵌入式 SVT 的实用性提供了初步支持。
