In clinical practice, indicators of random or irrelevant responses on MMPI protocols are typically not examined, and, if obtained, assumed to be the result of either gross psychopathology or attempts to malinger. A sample of 40 computer-generated random profiles and 40 profiles of forensic outpatients were compared on validity scales, clinical scales, and scales specially designed to detect randomness (TR index and Carelessness Scale). Results of discriminant analysis indicated differentiating patterns of responses with random profiles generally elevated. Further, the accuracy of several clinical decisions rules were evaluated. The "F greater than 80 and TR greater than 4" rule was found to have the greatest clinical utility at correctly classifying random responders.
在临床实践中，通常不会检查明尼苏达多相人格调查表（MMPI）记录中随机或不相关反应的指标，而且，如果获得此类指标，会认为这是严重精神病理学或伪装企图的结果。对40份计算机生成的随机剖面图样本和40份法医门诊患者的剖面图在效度量表、临床量表以及专门设计用于检测随机性的量表（TR指数和粗心量表）方面进行了比较。判别分析结果表明，随机剖面图的反应模式通常有所不同且得分较高。此外，还评估了几种临床决策规则的准确性。发现“F大于80且TR大于4”这一规则在正确分类随机反应者方面具有最大的临床实用性。
