Previous studies have typically focused on the ability of cognitive symptom validity tests to identify cognitive symptom exaggeration in the context of head injury or memory loss. Few published studies have examined the detection of simulated attention-deficit/hyperactivity disorder (ADHD) or reading disorder (RD). The present study examined the accuracy of symptom validity measures in the detection of simulated ADHD and RD. Results indicated that several commonly used symptom validity measures show good validity for detecting simulated ADHD and RD. Total Validity Indicator Profile (VIP) scores and hard item accuracy score from the Victoria Symptom Validity Test (VSVT) were the most accurate at distinguishing simulation of ADHD and RD from adequate effort. Percentages of control participants and participants in simulation conditions scoring below a specified cut score are provided to give clinicians an estimate of the simulator (true) positive and control (false) positive rates.
以往的研究通常聚焦于认知症状效度测试在头部受伤或记忆丧失背景下识别认知症状夸大的能力。很少有已发表的研究考察对模拟注意力缺陷多动障碍（ADHD）或阅读障碍（RD）的检测。本研究检验了症状效度测量在检测模拟ADHD和RD方面的准确性。结果表明，几种常用的症状效度测量在检测模拟ADHD和RD方面显示出良好的效度。来自维多利亚症状效度测试（VSVT）的总效度指标概况（VIP）分数和难题准确率得分在区分ADHD和RD的模拟与足够努力方面最为准确。提供了控制组参与者和处于模拟条件下得分低于特定划界分数的参与者的百分比，以便为临床医生提供模拟器（真）阳性率和控制组（假）阳性率的估计值。
