目的探讨遗忘型轻度认知障碍老年人长延迟回忆(N5)的相关因素,并建立长延迟回忆的多元线性回归方程.方法采用便利抽样法抽取248名于北京市某社区卫生服务中心就诊的老年人,在遗忘型轻度认知障碍的筛查过程中,利用听觉词语学习测验(AVLT)评估其记忆力,并收集其一般资料；以AVLT-长延迟回忆得分(N5)为因变量,以一般资料及AVLT-词语学习阶段的3次短时回忆得分(N1、N2、N3)及短延迟回忆得分(N4)为自变量,采用逐步回归分析法建立多元线性回归方程；比较听觉词语学习测验-长延迟回忆实际值(N5)与利用回归方程得到的预测值的差异.结果经多元线性逐步回归分析,得出N5对于N2、N3、N4的多元线性回归方程,长延迟回忆实际值(N5)与回归方程预测值之间无显著差异.结论听觉词语学习测验-词语学习阶段的第2、3次短时回忆得分(N2、N3)、短延迟回忆得分(N4)可作为预测长延迟回忆得分(N5)的主要参考指标；对检查对象进行遗忘型轻度认知障碍筛查时,可首先通过回归方程预测其长延迟回忆得分,得分≤4分者继续进行筛查,得分＞5分则停止,以便于人、财、物的集中,提高筛查效率.

Objective To establish a multiple regression equation of long delayed recall of the amnestic mild cognitive impairment,in order to predict the scores.Methods 248 old people were investigated by convenience sampling.Auditory verbal learning test (AVLT) was used to evaluate the ability of memory of the old people,and their general demographic data were collected.Multivariate linear regression analysis was conducted,the regression model was established and AVLT-long delayed recall scores (N5) to the predicted value got from the 3 times scores of study stage scores (N1,N2,N3) and short delayed recall (N4) of Auditory Verbal Learning Test were compared.Results The multiple linear regression equation between the variables was established.There was no significant difference between N5 and the predicted value.Conclusions N2,N3,N4 could be used to predict N5 during screening of amnestic mild cognitive impairment to make the screening process faster and briefer.When the score ≤4 points,the screening continues,if the score ＞5 points,the screening ceases in order to improve the efficiency of screening.
