目的探讨IQ损伤值评估在智力损伤鉴定中的应用价值。方法对266例智力损伤鉴定资料进行回顾性分析,采用“事前智力水平的估计方法”评估伤前IQ,按IQ损伤值(伤前与伤后IQ的差值)对智力损伤进行评定,并与根据原鉴定当时IQ评定的智力损伤结果及与专家意见进行比较。结果鉴定当时IQ评定结果与IQ损伤值评定结果不一致率为40.23%(107/266),二者一致性差(k=0.367);鉴定当时IQ评定结果与专家最终评定意见一致率为63.91%,而IQ损伤值评定结果与专家最终评定意见一致率为89.85%,一致性好于前者。结论在智力损伤鉴定中,根据IQ损伤值比根据鉴定当时IQ评定结果做出的鉴定结论更为科学。伤前IQ评估在智力损伤的司法鉴定中有较重要的应用价值。
Objective To explore the value of IQ damage assessment in the identification of intellectual impairment. Methods A retrospective analysis of 266 cases of intelligence damage identification data was performed. The preimplantation IQ was evaluated using “antecedent intelligence level estimation method ”, and the IQ damage was evaluated according to the IQ damage value (the difference between pre- and post-traumatic IQ) And compared with the results of intellectual impairment assessed according to the original IQ at that time and with expert opinions. Results The inconsistency between the IQ and IQ scores was 40.23% (107/266) at the time of identification. The consistency between them was not significant (k = 0.367). The consistency between IQ evaluation results and experts’ final assessment was 63.91% IQ injury assessment results and the final assessment of experts agreed rate was 89.85%, consistency is better than the former. Conclusion In the identification of intellectual impairment, it is more scientific to conclude based on the IQ damage value than the identification result of the IQ evaluation at the time of identification. Injury IQ assessment in the intellectual damage of forensic identification has more important value.
