Current guidelines for conducting symptom validity assessments require that professionals administer multiple symptom validity tests (SVTs) and that the SVTs selected for their evaluations provide nonredundant information. However, not many SVTs are currently available, and most of them rely on the same, (in)frequency-based, feigning detection strategy. In this context, the Inventory of Problems (IOP-29) could be a valuable addition to the assessor's toolbox because of its brevity (29 items) and its different approach to assessing the credibility of presented symptoms. As its ecological validity has been poorly investigated, the present study used a criterion groups design to examine the classification accuracy of the IOP-29 in a data set of 174 court-ordered psychological evaluations focused on psychological injury. The validity scales of the Minnesota Multiphasic Personality Inventory-2 Restructured Form and the total score of the Structured Inventory of Malingered Symptoms were used as criterion variables. Overall, the results of this study confirm that the IOP-29 is an effective measure (1.70 ≤ d ≤ 2.67) that provides valuable information when added to the multimethod assessment of symptom validity in civil forensic contexts.

IOP-29 的生态有效性：使用 MMPI-2-RF 和 SIMS 作为标准变量的后续研究。

当前进行症状有效性评估的指南要求专业人员进行多项症状有效性测试 (SVT)，并且为评估选择的 SVT 提供非冗余信息。然而，目前可用的 SVT 并不多，而且大多数都依赖于相同的、基于频率的伪装检测策略。在这种情况下，问题清单 (IOP-29) 可能是评估者工具箱的一个有价值的补充，因为它的简洁性（29 项）以及评估所呈现症状的可信度的不同方法。由于其生态有效性调查较少，本研究采用标准组设计来检验 IOP-29 在 174 项法院下令的针对心理伤害的心理评估的数据集中的分类准确性。明尼苏达多相人格量表 2 重组表的有效性量表和装病症状结构化量表的总分被用作标准变量。总体而言，本研究的结果证实，IOP-29 是一种有效的测量方法 (1.70 ≤ d ≤ 2.67)，在民事法医环境中添加到症状有效性的多方法评估中时，可以提供有价值的信息。（PsycInfo 数据库记录 (c) 2023 APA，保留所有权利）。
