虽然人们认识到，显着的认知缺陷是固有的许多精神疾病，有很少的研究是否赤字可以导致失败的症状有效性测试（SVT）的分数。分别对104例和178例精神病性障碍和非精神病性精神障碍患者在7个SVT上的表现进行了检查。分析表明，大多数这些SVT的特异性率为90%或更好的两个临床组。此外，只有7%的患者在精神病组和5%的患者在非精神病性精神病组产生假阳性分类的基础上伪装的标准类似于那些由Slick埃塔尔建议。(i.e.,两个或多个SVT失败或一个SVT失败，在统计学上显著差于机会率）。因此，这项研究表明，精神疾病通常不会对SVT的表现产生不利影响。
Although it is recognized that significant cognitive deficits are inherent in many psychiatric disorders, there is minimal research on whether the deficits can cause a failing score on symptom validity tests (SVTs). The performances of 104 and 178 patients with psychotic disorders and non-psychotic psychiatric disorders, respectively, on seven SVTs were examined. Analyses indicate that most of these SVTs have specificity rates of 90% or better for both clinical groups. Further, only 7% of patients in the psychotic group and 5% of patients in the non-psychotic psychiatric group produced false-positive classifications based on malingering criteria similar to those suggested by Slick etal. (i.e., failure of two or more SVTs or failure of one SVT at statistically significantly worse than chance rates). Consequently this research indicates that psychiatric disorders typically do not adversely affect SVT performance.
