Despite the value of the MMPI to the forensic assessment of malingering (exaggeration) of psychopathology, few studies have assessed the accuracy of the MMPI validity scales in criminal forensic populations. We administered the MMPI to 35 insanity defendants undergoing evaluation for fitness to stand trial and/or sanity at the time of the crime, who stood to benefit from being assessed as psychologically disturbed, and 39 subjects previously found not guilty by reason of insanity (NGRI), who did not stand to gain from such an assessment, Insanity defendants showed significantly more malingering than NGRI subjects, p less than .05. Racial differences did not affect the data. These findings support the efficacy of MMPI validity scales in assessing malingering within criminal forensic groups, and support the generalizability of the scales across race.
尽管明尼苏达多相人格测验（MMPI）对于法医评估精神病理学方面的诈病（夸大症状）具有重要价值，但很少有研究评估MMPI效度量表在刑事法医人群中的准确性。我们对35名接受审判能力和/或犯罪时精神状态评估的精神错乱被告进行了MMPI测试，这些被告若被评估为心理紊乱则可能从中受益；另外还对39名先前因精神错乱而被判无罪（NGRI）的受试者进行了测试，这些人不会从这种评估中获益。精神错乱被告表现出的诈病行为明显多于NGRI受试者，p值小于0.05。种族差异并未影响数据结果。这些发现支持了MMPI效度量表在评估刑事法医群体中诈病行为方面的有效性，也支持了这些量表在不同种族间的通用性。
