People with seizure disorders experience elevated rates of psychopathology, often undiagnosed and untreated. Accurate diagnosis of psychopathology remains an important goal of quality health care for people with seizure disorders. One of the most widely used dimensional measures of psychopathology is the Minnesota Multiphasic Personality Inventory-Second Edition (MMPI-2). Research in heterogeneous mental health samples suggests that the 2008 revision of this measure, the Minnesota Multiphasic Personality Inventory-Second Edition-Restructured Form (MMPI-2-RF), offers better construct fidelity and more cost-effective administration. This study seeks to extend research on MMPI-2-RF scale elevations to a sample of people with seizure disorders.
In a consecutive, heterogeneous sample of people with seizure disorders, MMPI-2 and MMPI-2-RF scores were compared in terms of categorical classification agreement (clinically elevated versus not clinically elevated). Scores were also compared in terms of variance attributable to diagnosis-specific items, general demoralization, subtle items, social desirability, and demographic factors.
Scores on MMPI-2 and MMPI-2-RF provided a statistically significant level of agreement between corresponding clinical diagnostic scales ranging from 68% to 84%. Most classification disagreement was attributable to MMPI-2 clinical scale elevations when MMPI-2-RF scales were not elevated. Regression analysis supported the interpretation that general demoralization, subtle items, social desirability, and demographic factors led to MMPI-2 clinical scale elevations.
The results provide evidence that in the context of strong psychopathology classification agreement, the MMPI-2-RF restructured clinical scales provide better construct fidelity compared with the more trait heterogeneous MMPI-2 clinical scales. These results should encourage clinicians to use the MMPI-2 Restructured Form (MMPI-2-RF) for improved psychopathology assessment compared with the MMPI-2 in patients with seizure disorders.
癫痫症患者出现精神病理学症状的比例较高，且这些症状往往未得到诊断和治疗。准确诊断精神病理学症状仍然是癫痫症患者高质量医疗保健的一个重要目标。精神病理学最广泛使用的维度测量方法之一是明尼苏达多相人格调查表第二版（MMPI-2）。对异质性心理健康样本的研究表明，该量表在2008年的修订版，即明尼苏达多相人格调查表第二版重组版（MMPI-2-RF），具有更好的结构效度和更高的管理成本效益。本研究旨在将对MMPI-2-RF量表升高情况的研究扩展到癫痫症患者样本。
在一个连续的、异质性的癫痫症患者样本中，比较了MMPI-2和MMPI-2-RF在分类一致性（临床升高与非临床升高）方面的得分。还比较了得分在归因于特定诊断项目、总体士气低落、细微项目、社会期望和人口统计学因素方面的差异。
MMPI-2和MMPI-2-RF的得分在相应临床诊断量表之间提供了具有统计学意义的一致性水平，范围从68%到84%。当MMPI-2-RF量表未升高时，大多数分类不一致归因于MMPI-2临床量表升高。回归分析支持这样的解释，即总体士气低落、细微项目、社会期望和人口统计学因素导致了MMPI-2临床量表升高。
结果提供了证据，表明在精神病理学分类一致性较强的情况下，与特质异质性更强的MMPI-2临床量表相比，MMPI-2-RF重组临床量表具有更好的结构效度。这些结果应鼓励临床医生在癫痫症患者中使用MMPI-2重组版（MMPI-2-RF），以比MMPI-2更好地评估精神病理学症状。
