颅脑损伤后社会功能与精神伤残等级评定关系的研究

Correlation between social function and mental disability level after craniocerebral injury

目的探讨颅脑损伤后社会功能受损程度与精神伤残等级的客观评定关系。方法收集汕头大学司法鉴定中心2009年~2020年201例鉴定案例,应用成人智残评定量表(Intelligengce Disability Rating Scale,IDRS)与改良Barthel指数评定量表(Modified Barthel Index,MBI)评估社会功能受损程度。结果颅脑损伤所致的精神伤残鉴定案例中,精神伤残的轻、中、重度与社会功能受损程度之间的差异有统计学意义(P<0.05),与颅脑损伤部位数目总和之间差异无统计学意义(P>0.05)。不同精神伤残程度间IDRS、MBI得分差异具有统计学意义(P<0.05),精神伤残的轻、中、重度对应的IDRS和MBI量表界限区间分别为0~9分和85~100分、10~14分和46~85分、15~20分和0~45分。结论在进行精神伤残严重程度评定时,可用评定社会功能受损程度的IDRS、MBI对精神伤残程度进行区分,评定社会功能可为精神伤残等级评定提供相对客观的依据。

Objective To explore the relationship between the degree of social function impairment and the level of mental disability after craniocerebral injury.Methods 201 forensic cases from 2009 to 2020 in Shantou University forensic center were collected.The degree of social function impairment was assessed by IDRS(intelligence disability rating scale)and MBI(modified Barthel Index).Results In the identification cases of mental disability caused by craniocerebral injury,there was significant difference between the light,medium and severe mental disability and the degree of social function impairment(P<0.05),but there was no significant difference between the light,medium and severe mental disability and the total number of craniocerebral injury sites(P>0.05).There were significant differences in the scores of IDRs and MBI among different degrees of mental disability(P<0.05).The limits of IDRs and MBI for mild,moderate and severe mental disability were 0-9 and 85-100,10-14 and 46-85,15-20 and 0-45,respectively.Conclusion In the assessment of the severity of mental disability,IDRS and MBI can be used to distinguish the degree of mental disability.The assessment of social function can provide a relatively objective basis for the assessment of mental disability.
