摘　　要：目的考查认知伪装甄别测验对认知伪装的甄别能力。方法用认知伪装甄别测验对123名接受劳动能力鉴定的病人、35名脑损害病人和263名正常人进行测试。结果鉴定组的数字迫选分低于对照组2.6个标准差、低于脑损害组0.8个标准差,图符迫选分低于对照组2.2个标准差、低于脑损害组0.3个标准差;按概率分标准,鉴定组有32人（26.0%）判为伪装,按划界分标准,鉴定组有69人（56.1%）判为伪装,按得分模式评判,鉴定组有41人（33.3%）判为伪装;判别分析显示六指标组合对鉴定组与对照组的归类正确率为91.2%,对鉴定组与脑损害组的归类正确率为68.4%,其中数字1-10和数字11-20是两个最敏感的指标。结论认知伪装甄别测验对伪装认知损害有较好的甄别能力。Objective To evaluate effect of cognitive malingering screening test to detect malingered cognitive impairment. Methods The cognitive malingering screening test （CNST） was administered 123 adults received disability assessment （ Disable group）, 35 patients with brain damage （ Damage group）, and 263 normal adults （ Normal group）. Results On the digital forced-choice test, the average performance of disable group was 2.6 or 0.8 standard deviations worse than that of normal group or damage group. On the figure forced-choice test, the disable group was 2.2 or 0.3 standard deviations worse than the normal group or damage group. On the base of chance level, there were 32 （26. 0% ） malingers in the disable group. According to cut-off standard, 69 （56.1%） persons in the disable group were judged as malingers. In the light of performance model, 41 （33.3%） disable adults were recognized as malingers. A discriminant function analysis using six test scores resulted in 91.2% correct classification of the disable group and normal group, and 68.4% correct classification of the disable group and damage group, digital item 1 - 10 and digital item 11 -20 were the most effective indicators. Conclusion The cognitive malingering screening test is useful instrument in detecting feigned cognitive impairment.
