目的探讨2项必选数字记忆测验得分在精神发育迟滞患者司法鉴定与非鉴定组的异同。方法精神发育迟滞(MR)患者司法精神医学鉴定者43例,非鉴定者44例,分别进行2项必选数字记忆测验(BFDMT)和韦氏成人智力量表测查(WAIS-RC),对鉴定组和非鉴定组之间的结果进行比较和分析。结果MR鉴定组总分、容易条目得分明显低于非鉴定组(分别为P<0.05、P<0.001),在困难条目得分上两组之间无显著性差异(P>0.05);鉴定组的智商、言语智商值都明显低于非鉴定组,有显著性差异(P<0.05);操作智商两组之间无显著性差异(P>0.05)。MR鉴定组BFDMT测验总分、容易条目分、困难条目分与WAIS-RC测验的智商总分、言语智商、操作智商分之间均呈显著正相关。结论BFDMT得分的高低有助于司法鉴定MR患者的诊断。
Objective To explore the similarities and differences between the two mandatory digital memory test scores in judicial appraisal and non-appraisal of patients with mental retardation. Methods Forty-three patients with mental retardation (MR) were identified as psychiatric medical appraiser and 44 non-appraised patients. Two mandatory digital memory tests (BFDMT) and WAIS-RC The results between certified and non-identified groups were compared and analyzed. Results There was no significant difference between the two groups (P> 0.05). The score of easy item in MR group was significantly lower than that of non-identified group (P <0.05, P <0.001) IQ, verbal IQ value were significantly lower than the non-identified group, there was a significant difference (P <0.05); operation IQ between the two groups no significant difference (P> 0.05). There was a significant positive correlation between BFDMT score, easy item score and difficult item score in the MR group and the total scores of IQ, verbal IQ, and IQ in the WAIS-RC test. Conclusion The level of BFDMT score is helpful to the forensic diagnosis of MR patients.
