OBJECTIVE This study investigated performance validity in the understudied Romanian clinical population by exploring classification accuracies of the Dot Counting Test (DCT) and the first Romanian performance validity test (PVT) (Memory of Objects and Digits and Evaluation of Memory Malingering/MODEMM) in a heterogeneous clinical sample. METHODS We evaluated 54 outpatients (26 females; MAge = 62.02; SDAge = 12.3; MEducation = 2.41, SDEducation = 2.82) with the Test of Memory Malingering 1 (TOMM-1), Rey Fifteen Items Test (Rey-15) (free recall and recognition trials), DCT, MODEMM, and MMSE/MoCA as part of their neuropsychological assessment. Accuracy parameters and base failure rates were computed for the DCT and MODEMM indicators against the TOMM-1 and Rey-15. Two patient groups were constructed according to psychometrically defined credible/noncredible performance (i.e., pass/fail both TOMM-1 and Rey-15). RESULTS Similar to other cultures, a cutoff of ≥18 on the DCT E score produced the best combination between sensitivity (0.50-0.57) and specificity (≥0.90). MODEMM indicators based on recognition accuracy, inconsistencies, and inclusion false positives generated 0.75-0.86 sensitivities at ≥0.90 specificities. Multivariable models of MODEMM indicators reached perfect sensitivities at ≥0.90 specificities against two PVTs. Patients who failed the TOMM-1 and Rey-15 were significantly more likely to fail the DCT and MODEMM than patients who passed both PVTs. CONCLUSIONS Our results offer proof of concept for the DCT's cross-cultural validity and the applicability of the MODEMM on Romanian clinical examinees, further recommending the use of heterogeneous validity indicators in clinical assessments.

东欧的有效性评估：在罗马尼亚混合临床样本中对点计数测试和 MODEMM 与 TOMM-1 和 Rey-15 进行交叉验证。

目的 本研究通过探索点计数测试 (DCT) 和第一个罗马尼亚表现有效性测试 (PVT)（对象和数字的记忆以及记忆欺骗/MODEMM 的评估）的分类准确性，调查了罗马尼亚临床人群的表现有效性。异质临床样本。方法 我们使用记忆欺骗测试 1 (TOMM-1)、Rey 十五项测试 (Rey-15)（自由回忆）评估了 54 名门诊患者（26 名女性；MAge = 62.02；SDAge = 12.3；MEducation = 2.41，SDEducation = 2.82）。和识别试验）、DCT、MODEMM 和 MMSE/MoCA 作为神经心理学评估的一部分。根据 TOMM-1 和 Rey-15 计算 DCT 和 MODEMM 指标的精度参数和基本故障率。根据心理测量定义的可信/不可信表现（即 TOMM-1 和 Rey-15 均通过/失败）构建两个患者组。结果 与其他培养类似，DCT E 评分≥18 的截止值产生了敏感性 (0.50-0.57) 和特异性 (≥0.90) 之间的最佳组合。基于识别准确性、不一致和包含误报的 MODEMM 指标在 ≥0.90 特异性下产生 0.75-0.86 灵敏度。MODEMM 指标的多变量模型针对两个 PVT 达到了 ≥0.90 特异性的完美灵敏度。未通过 TOMM-1 和 Rey-15 的患者比通过两项 PVT 的患者更有可能未通过 DCT 和 MODEMM。结论 我们的结果为 DCT 的跨文化有效性和 MODEMM 对罗马尼亚临床受试者的适用性提供了概念证明，进一步建议在临床评估中使用异质有效性指标。
