The Personality Assessment Inventory (PAI) is a widely used self-report questionnaire designed to detect and quantify dimensions of adult psychopathology. Previous studies that examined the ability of the PAI to differentiate between patients with psychogenic nonepileptic seizures (PNES) and those with epilepsy (EPIL) have yielded inconsistent results. We compared the full PAI profiles of 62 patients with PNES, 55 with EPIL, and 45 normal control (NC) participants to determine the diagnostic accuracy of the PAI. We also sought to highlight psychopathologic symptoms that may inform psychological treatment of patients with PNES or epilepsy. PNES and EPIL patients reported more somatic concerns and symptoms of anxiety and depression than did NC persons. PNES patients reported more unusual somatic symptoms, as well as greater physical symptoms of anxiety and depression than did patients with EPIL. Classification accuracy of the "NES Indicator" was not much better than chance, whereas the Conversion subscale alone had reasonable sensitivity (74%) and specificity (67%). Overall, the PAI demonstrated only moderate classification accuracy in an epilepsy monitoring unit sample. However, the inventory appears to identify specific psychopathological symptoms that may be targets of psychological/psychiatric intervention.
人格评估量表（PAI）是一种广泛使用的自陈式问卷，旨在检测和量化成人精神病理学的维度。先前研究检查了 PAI 区分心因性非癫痫性发作（PNES）患者和癫痫（EPIL）患者的能力，结果不一致。我们比较了 62 名 PNES 患者、55 名 EPIL 患者和 45 名正常对照组（NC）参与者的完整 PAI 图谱，以确定 PAI 的诊断准确性。我们还试图强调可能为 PNES 或癫痫患者的心理治疗提供信息的精神病理症状。PNES 和 EPIL 患者比 NC 个体报告了更多的躯体问题和焦虑、抑郁症状。PNES 患者比 EPIL 患者报告了更多不寻常的躯体症状，以及更多的焦虑和抑郁躯体症状。“NES 指标”的分类准确性并不比随机好多少，而单独的转换分量表具有合理的敏感性（74%）和特异性（67%）。总体而言，PAI 在癫痫监测单元样本中仅表现出中等的分类准确性。然而，该量表似乎可以识别出特定的精神病理学症状，这些症状可能是心理/精神病干预的目标。
