Assessing the credibility of symptoms is critical to neuropsychological assessment in both clinical and forensic settings. To this end, the Inventory of Problems-29 (IOP-29) and its recently added memory module (Inventory of Problems-Memory; IOP-M) appear to be particularly useful, as they provide a rapid and cost-effective measure of both symptom and performance validity. While numerous studies have already supported the effectiveness of the IOP-29, research on its newly developed module, the IOP-M, is much sparser. To address this gap, we conducted a simulation study with a community sample ( = 307) from the United Kingdom. Participants were asked to either (a) respond honestly or (b) pretend to suffer from mTBI or (c) pretend to suffer from depression. Within each feigning group, half of the participants received a description of the symptoms of the disorder to be feigned, and the other half received both a description of the symptoms of the disorder to be feigned and a warning not to over-exaggerate their responses or their presentation would not be credible. Overall, the results confirmed the effectiveness of the two IOP components, both individually and in combination.
评估症状的可信度对于临床和法医神经心理学评估至关重要。为此，问题清单-29（Inventory of Problems-29，IOP-29）及其最近添加的记忆模块（Inventory of Problems-Memory，IOP-M）似乎特别有用，因为它们提供了一种快速且具有成本效益的症状和表现有效性的衡量方法。虽然已经有许多研究支持了 IOP-29 的有效性，但对于其新开发的模块 IOP-M 的研究要少得多。为了解决这一差距，我们对来自英国的社区样本（ = 307）进行了一项模拟研究。参与者被要求要么（a）诚实地回答，要么（b）假装患有 mTBI，要么（c）假装患有抑郁症。在每个模拟组中，一半的参与者收到了要模拟的疾病症状描述，另一半则收到了要模拟的疾病症状描述和不要过度夸大其反应或其表现将不可信的警告。总的来说，结果证实了这两个 IOP 组件的有效性，无论是单独使用还是组合使用。
