During the Psychological Consultative Examination (PCE) for Social Security Disability evaluations, there is a need for symptom validity measures to validate the findings for claims of disability (Chafetz, 2010 ). The "A" Random Letter Test of Auditory Vigilance (A-Test) is a simple auditory continuous performance test utilized as part of a comprehensive mental status examination (Strub & Black, 1993 ). The present study validates the use of the A-Test as a symptom validity measure easily administered as part of the PCE for Social Security Disability evaluations. This study shows that the A-Test is well correlated with other symptom validity measures, discriminates multiple symptom validity failure from nonmultiple failure, and has good classification accuracy statistics in two different studies of these claimants. The A-Test can thus easily be used as a symptom validity measure in professional psychological examinations of Social Security claimants without additional cost or much added time to the evaluation.
在社会保障残疾评估的心理咨询检查（PCE）过程中，需要症状效度测量方法来验证残疾索赔的检查结果（查菲茨，2010年）。“A”听觉警觉随机字母测试（A测试）是一种简单的听觉持续操作测试，用作综合精神状态检查的一部分（斯特鲁布和布莱克，1993年）。本研究验证了A测试作为一种症状效度测量方法的用途，该方法易于实施，可作为社会保障残疾评估PCE的一部分。这项研究表明，A测试与其他症状效度测量方法具有良好的相关性，能够区分多次症状效度失败和非多次失败，并且在对这些索赔人的两项不同研究中具有良好的分类准确性统计数据。因此，A测试可以很容易地用作对社会保障索赔人进行专业心理检查时的症状效度测量方法，而无需额外费用或在评估中增加太多时间。
