刑事法医鉴定由于考生的反应不可靠而变得复杂。由于缺乏对评估的个人投入，严重的精神疾病和低认知能力，可能会出现不可靠的反应。在本研究中，31%的明尼苏达多相人格量表- 2重构表（MMPI-2-RF; Ben-Porath & Tellegen, 2008/2011）由于随机或固定反应（vin -r或TRIN-r量表的T得分≥80）而无效，在能力恢复治疗的背景下评估审前刑事被告样本。分层回归模型显示，通过不一致的精神症状报告来衡量的症状夸大变量，在预测随机反应和固定反应方面的贡献超过教育和智力功能。以情绪障碍来衡量的精神病理变量，在控制了认知能力的估计后，能更好地预测固定反应，但不能改善对随机反应的预测。这些发现表明，随机反应和固定反应不仅受到教育和智力功能的影响，还受到故意夸大和精神病理方面的影响。智力功能、努力和反应风格的测量应考虑与自我报告人格测量相结合，以排除无效档案的竞争性假设。
ABSTRACT Criminal forensic evaluations are complicated by the risk that examinees will respond in an unreliable manner. Unreliable responding could occur due to lack of personal investment in the evaluation, severe mental illness, and low cognitive abilities. In this study, 31% of Minnesota Multiphasic Personality Inventory–2 Restructured Form (MMPI–2–RF; Ben-Porath & Tellegen, 2008/2011) profiles were invalid due to random or fixed-responding (T score ≥ 80 on the VRIN–r or TRIN–r scales) in a sample of pretrial criminal defendants evaluated in the context of treatment for competency restoration. Hierarchical regression models showed that symptom exaggeration variables, as measured by inconsistently reported psychiatric symptoms, contributed over and above education and intellectual functioning in their prediction of both random responding and fixed responding. Psychopathology variables, as measured by mood disturbance, better predicted fixed responding after controlling for estimates of cognitive abilities, but did not improve the prediction for random responding. These findings suggest that random responding and fixed responding are not only affected by education and intellectual functioning, but also by intentional exaggeration and aspects of psychopathology. Measures of intellectual functioning and effort and response style should be considered for administration in conjunction with self-report personality measures to rule out rival hypotheses of invalid profiles.
