The relationship between IQ and nine effort indicators was examined in a sample of 189 neuropsychology clinic outpatients who were not in litigation or attempting to obtain disability. Participants with the lowest IQ (50-59) failed approximately 60% of the effort tests, while patients with an IQ of 60 to 69 failed 44% of effort indicators, and individuals with borderline IQ (70 to 79) exhibited a 17% failure rate. All patients with IQ < 70 failed at least one effort test. Cutoffs for the Warrington Recognition Memory Test (Words) and Finger Tapping maintained the highest specificities in low IQ samples.
在189名未处于诉讼或申请残疾状态的神经心理学门诊患者样本中，研究了智商（IQ）与九个努力程度指标之间的关系。智商最低（50 - 59）的参与者在大约60%的努力程度测试中未通过，而智商在60至69之间的患者有44%的努力程度指标未通过，处于临界智商（70至79）的个体失败率为17%。所有智商低于70的患者至少有一项努力程度测试未通过。在低智商样本中，韦氏记忆测验（词语）和手指敲击测试的临界值具有最高的特异性。
