Objective evaluation of simulation in low back pain is currently not possible. A new simulation scale based on subject response to 103 pain words has shown promise in discriminating patients with low back pain from those simulating low back pain. Administration of this scale to 1679 individuals who were injured at work produced a 10.4% sample with scores in the simulation range. This subsample projected more intense pain and were disabled longer. These findings were replicated in a second study in which treating physicians rated the degree of physical pathology and symptom exaggeration blind to patient classification by the Low Back Pain Simulation Scale. Medical assessment indicated less organic pathology and greater symptom exaggeration among patients classified as simulators providing a measure of support for the validity of the simulation scale.
目前尚无法对腰痛模拟进行客观评估。一种基于受试者对103个疼痛词汇反应的新模拟量表，在区分腰痛患者和模拟腰痛患者方面显示出了前景。对1679名工伤人员使用该量表，结果显示有10.4%的样本得分处于模拟范围内。这个子样本预计会有更强烈的疼痛，且残疾时间更长。这些发现 在第二项研究中得到了重复，在该研究中，治疗医生在不知道患者根据腰痛模拟量表分类的情况下，对身体病理学程度和症状夸大程度进行了评分。医学评估表明，被归类为模拟者的患者中，器质性病理学较少，症状夸大较多，这为模拟量表的有效性提供了一定程度的支持。
