【摘要】：目的:修订临床记忆量表中的词语配对联想学习测验(VPALT)的老年常模并检验其效度和信度。方法:在北京取60~85岁正常老人825名(用于建立常模和信度检验)和轻度认知损害(MCI)患者91名(用于效度检验),完成VPALT、瑞氏听觉词语学习测验(RAVLT)、蒙特利尔认知评估量表(MoCA)等神经心理测验,并选取其中25名正常老人于2~5周后进行VPALT重测。把被试按年龄和受教育程度分组以建立常模。效度检验采用实证效度和效标效度,效标工具包括RAVLT和MoCA,并进行ROC曲线分析。信度检验使用内部一致性系数和重测信度。结果:不同年龄组和受教育程度组VPALT得分存在差异(P0.001),年龄越低或受教育程度越高VPALT得分越高。效度检验发现,VPALT得分与RAVLT的即时回忆总分、MoCA的延迟回忆得分、MoCA总分均呈正相关(r=0.56、0.46、0.49,均P0.001);正常老年人群的VPALT得分高于MCI患者[(6.9±4.2)vs.(4.2±3.2),P0.001];根据ROC曲线结果,VPALT的敏感度为81.4%,特异度为64.4%。信度检验发现,VPALT的Cronbachα系数为0.86,其中容易词对和困难词对两个分测验的α系数分别为0.78和0.83;VPALT的重测信度为0.80,其中容易词对和困难词对两个分测验的重测信度分别为0.77和0.71。结论:本研究修订了词语配对联想学习测验60~85岁健康老人的年龄和受教育程度常模,其效度、信度检验符合心理测量学要求,可作为老年人记忆能力检测和MCI临床诊断的定量参照指标。
[Abstract]:Objective: to revise the geriatric norm of word pair associative learning test (VPALTT) in clinical memory scale and to test its validity and reliability. Methods: 825 normal people aged 60 to 85 years old (used to establish norm and reliability test) and mild degree were selected in Beijing. 91 patients with cognitive impairment (MCI) received neuropsychological tests such as validity test, VPALTT, RAVLTT, Montreal Cognitive Assessment scale (MOCA), etc. 25 of them were selected to retest VPALT after 2 weeks. The subjects were divided into two groups according to their age and education level to establish the norm. The validity test was conducted by empirical validity and standard validity. The reliability test uses internal consistency coefficient and retest reliability. Results: there are differences in VPALT scores of different age groups and educated groups (P 0.001), the lower the age or the educational level, the lower the age or the educational level. The higher the score of VPALT was, the higher the score of VPALT was. The validity test showed that the score of VPALT was positively correlated with the total score of delayed recall of RAVLT and the total score of RAVLT was 0.560.46 卤0.49, all of which was P 0.0010.The VPALT score of normal elderly people was higher than that of MCI patients [6.9 卤4.2)vs.(4.2 卤3.2P0.001], and according to the result of ROC curve, VPALT was significantly higher than that of MCI patients. The sensitivity was 81.4 and the specificity was 64.4. The reliability test found that the Cronbach 伪 coefficient of VPALT was 0.86, and the 伪 coefficient of easy word pair and difficult word pair subtest was 0.78 and 0.83VPALT, respectively, and the re-test reliability of easy word pair and difficult word pair was 0.80. The test-retest reliability of the test was 0.77 and 0.71 respectively. Conclusion: this study revised the norm of age and education level of the healthy people aged 6085 years old in the word pair associative learning test. The test of validity and reliability meets the requirement of psychometrics and can be used as a quantitative reference index for the detection of memory ability and the clinical diagnosis of MCI in the elderly.
