The objective of this study was to assess the MOXO-d-CPT utility in detecting feigned ADHD and establish cutoffs with adequate specificity and sensitivity. : The study had two phases. First, using a prospective design, healthy adults who simulated ADHD were compared with healthy controls and ADHD patients who performed the tasks to the best of their ability ( = 47 per group). Participants performed the MOXO-d-CPT and an established performance validity test (PVT). Second, the MOXO-d-CPT classification accuracy, employed in Phase 1, was retrospectively compared with archival data of 47 ADHD patients and age-matched healthy controls. : Simulators performed significantly worse on all MOXO-d-CPT indices than healthy controls and ADHD patients. Three MOXO-d-CPT indices (attention, hyperactivity, impulsivity) and a scale combining these indices showed adequate discriminative capacity. : The MOXO-d-CPT showed promise for the detection of feigned ADHD and, pending replication, can be employed for this aim in clinical practice and ADHD research.
本研究旨在评估 MOXO-d-CPT 在检测伪装 ADHD 方面的效用，并确定具有足够特异性和敏感性的截断值。研究分为两个阶段。第一阶段采用前瞻性设计，将模拟 ADHD 的健康成年人与健康对照组和尽力完成任务的 ADHD 患者进行比较（每组 47 人）。参与者完成了 MOXO-d-CPT 和一项既定的绩效有效性测试（PVT）。第二阶段，将第一阶段中使用的 MOXO-d-CPT 分类准确性与 ADHD 患者和年龄匹配的健康对照组的 47 例档案数据进行回顾性比较。模拟者在 MOXO-d-CPT 的所有指标上的表现均明显差于健康对照组和 ADHD 患者。三个 MOXO-d-CPT 指标（注意力、多动、冲动）和一个结合这些指标的量表显示出足够的区分能力。MOXO-d-CPT 有望用于检测伪装的 ADHD，在得到复制之前，可在临床实践和 ADHD 研究中用于此目的。
