摘要
目的探讨以二项必选数字记忆测验(BFDMT)的得分来反映精神发育迟滞患者韦氏智力测验成绩真实程度的可能性。方法对53例精神发育迟滞患者进行二项必选数字记忆测验(BFDMT)和韦氏成人智力量表测查(WAIS-RC),并有两位鉴定医师根据病史、临床经验和中国精神障碍分类与诊断标准第3版(CCMD-3)对精神发育迟滞的伪装和智力情况进行评定。对BFDMT判断的伪装与临床鉴定的有无伪装之间进行比较,有无伪装的BFDMT得分与WAIS-RC测验成绩之间的差异和相关性。结果53例精神发育迟滞患者医生判定有19例伪装(占35.8%),BFDMT测查结果判定伪装27例(占50.9%)。根据智商测定值将精神发育迟滞分为4个等级。医生判定的有无伪装在不同智商等级间无显著性差异(P>0.05),而BFDMT判断的有无伪装在不同智商等级间有显著性差异,智商值在中度智缺范围的差异较明显(P<0.01)。BFDMT判定的伪装组智商、言语智商和操作智商值都明显低于非伪装组,两者间均有非常显著性差异(P<0.01)。BFDMT测验总分、困难条目分、容易条目分与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得分的高低在一定程度上能够反映被试者WAIS-RC测验成绩的真实程度。
Objective To explore possibility of the scores of binomial forced-choice digit memory test （BFDMT） reflecting the true degree of Wechsler adult intelligence scale （WAIS-RC）in the patients with mental retardation. Methods 53 subjects with mental retardation were measured with binomial forced-choice digit memory test and Wechsler adult intelligence scale. Two authenticator assessed the camouflage and intelligence of patients with mental retardation according to history,clinical experience and Chinese classification and diagnostic criteria of mental disorder-3. We carried on a comparison to the camouflage in BFDMT judgment and to make sure whether there were camouflages or not in clinical authenticate. The correlation between the scores of camouflage in BFDMT and the test result in WAIS-RC were compared. Results Among the 53 subjects with mental retardation, 19（35.8%） subjects were judged to be camouflages by authenticator, while 27（50.9%） by BFDMT. According to the intelligence quotient, mental retardation was rated normal,edge appearance, light degree and medium degree. In different rating of intelligence quotient, no significant difference was found in clinical authenticate （P〉0.05）. But significant difference was found in BFDMT judgement, especially in medium degree mental retardation （P〈0.01）. The intelligence quotient,the speech intelligence quotient and the operation intelligence quotient in the camouflage group was markedly lower than non-camouflage group in BFDMT. There was significant difference between the two groups. In BFDMT test consult, the total scores ,items in difficulty and items in easiness were correlated with the scores of intelligence quotient, speech intelligence quotient and operation intelligence quotient positively. Conclusion To some extent, the level of scores in BFDMT can reflect the true degree of the WAIS- RC test result.
