Compared to other Western countries, malingering research is still relatively scarce in the United Kingdom, partly because only a few brief and easy-to-use symptom validity tests (SVTs) have been validated for use with British test-takers. This online study examined the validity of the Inventory of Problems-29 (IOP-29) in detecting feigned schizophrenia and random responding in 151 British volunteers. Each participant took three IOP-29 test administrations: (a) responding honestly; (b) pretending to suffer from schizophrenia; and (c) responding at random. Additionally, they also responded to a schizotypy measure (O-LIFE) under standard instruction. The IOP-29's feigning scale (FDS) showed excellent validity in discriminating honest responding from feigned schizophrenia (AUC = .99), and its classification accuracy was not significantly affected by the presence of schizotypal traits. Additionally, a recently introduced IOP-29 scale aimed at detecting random responding (RRS) demonstrated very promising results.
与其他西方国家相比，诈病研究在英国仍然相对较少，部分原因是只有少数简短且易于使用的症状效度测试（SVT）已被验证可用于英国考生。这项在线研究检验了问题清单-29（IOP-29）在检测151名英国志愿者伪装精神分裂症和随机作答方面的效度。每位参与者进行了三次IOP-29测试：（a）诚实作答；（b）假装患有精神分裂症；（c）随机作答。此外，他们还在标准指导下对一种分裂型特质测量工具（O-LIFE）做出反应。IOP-29的诈病量表（FDS）在区分诚实作答和伪装精神分裂症方面显示出极佳的效度（曲线下面积 = 0.99），并且其分类准确性不受分裂型特质存在的显著影响。此外，最近推出的旨在检测随机作答的IOP-29量表（RRS）显示出非常有前景的结果。
