目的 探讨交通事故致颅脑外伤伤者智残评定的最佳方法。方法 采用4种智力评估方法对被鉴定人的智力和认知状况进行评估。结果 与智力迟滞诊断作为金标准相比较,事件相关电位P300评定结果呈显著正相关(125例,r(?)=0.952,P<0.01),成人智残评定量表结果呈显著正相关(129例,r(?)=0.963,P<0.01),韦氏成人智力测量总智商(IQ)评定结果呈无明显相关(4例,r(?)=0.099,P>0.05)。结论 根据智力迟滞诊断、事件相关电位测定P300、成人智残量表评定、韦氏成人智力测量等多种方法进行综合分析,可准确评定被鉴定者智残水平。如被评定者有伪装倾向,则不宜采用韦氏智力测量方法进行评估。
Objective To explore the best method of assessing mental retardation of traumatic brain injury in traffic accidents. Methods Four kinds of intelligence assessment methods were used to evaluate the intelligence and cognitive status of the appraisers. Results Compared with the gold standard, the results showed that there was a significant positive correlation between event-related potentials P300 assessment (125 cases, r (?) = 0.952, P <0.01) (R = 0.963, P <0.01). There was no significant correlation between the results of Wechsler adult IQ test and IQ test (4 cases, r = 0.99, P> 0.05). Conclusions According to the comprehensive assessment of the diagnosis of mental retardation, the event-related potential measurement P300, the assessment of adult mental retardation scale, Webster’s adult intelligence, etc., the level of mental retardation can be accurately assessed. If the assessor has a disguise tendency, it is not advisable to use Wechsler’s intelligence measurement method to evaluate.
