Three expert MMPI judges classified 100 psychiatric inpatients as psychotic or non-psychotic on the basis of their MMPIs. Validity scale data, as well as clinical scale scores, were included for 50 of the profiles, while the validity scale scores were withheld from the judges for the remaining 50 profiles. Within each of the above two groups, half had a "positive" validity scale sign (a defensive validity scale configuration defined as L or K greater than or equal to 70, or both greater than or equal to 60) and half had a negative validity scale sign, indicating a lack of defensiveness. Using actual diagnosis as the external criterion, results indicated that the majority of defensive psychotic patients produced clinical scale configurations which appeared nonpsychotic to the judges. Conversely, the majority of nondefensive nonpsychotics produced psychotic-appearing clinical scale configurations. These two types of test misses suggest that K corrections on MMPI scales relating to psychosis are not optimal for psychiatric inpatients. Guidelines were developed for interpreting defensive profiles.
三位明尼苏达多相人格调查表（MMPI）专家根据100名精神科住院患者的MMPI将其分类为精神病性或非精神病性。50份档案包含效度量表数据以及临床量表分数，而其余50份档案的效度量表分数未提供给评估人员。在上述两组中，每组一半具有“阳性”效度量表迹象（一种防御性效度量表构型，定义为L或K大于或等于70，或两者均大于或等于60），另一半具有阴性效度量表迹象，表明缺乏防御性。以实际诊断作为外部标准，结果表明，大多数防御性精神病患者产生的临床量表构型在评估人员看来是非精神病性的。相反，大多数非防御性非精神病患者产生的临床量表构型看起来像是精神病性的。这两种测试失误表明，MMPI上与精神病相关量表的K校正对于精神科住院患者并非最佳。制定了解读防御性档案的指南。
