摘要目的 探讨改良版简短认知能力测验记忆子测验(SKT-M)在中国中老年人群的适用性.方法 选取2017年3月1日至10月31日于中国科学院大学宁波华美医院行择期大隐静脉结扎手术的患者132例及其陪同家属96例,年龄55～75岁,随机数字表法分为SKT-M测验组(n=121)与听觉词语学习测验华山版(AVLT-H)测验组(n=107),两组受试者分别于术前1天与术后第2天进行两次各自相应神经心理测验.结果 两组受试者的一般资料与2个评测时间点各神经心理测验指标差异均无统计学意义(均P＞0.05),故将两者数据整合以进行SKT-M与AVLT-H的对比分析.AVLT-H测验的即刻回忆低分率(2.4％)与延迟回忆低分率(5.7％)均显著高于SKT-M测验的即刻回忆低分率(12.1％)与延迟回忆低分率(20.5％),差异均有统计学意义(x2=8.138、11.167,均P＜0.01).AVLT-H测验的影响因素显著多于SKT-M测验.SKT-M即刻回忆测验的第2次得分为(23.1±5.4)分,高于第1次的(21.9±5.1)分,差异有统计学意义(t=-3.971,P＜0.001),表明其学习效应显著.结论 改良版SKT-M对55～75岁年龄段老年人群具有更好的适用性,其学习效应较为明显.

abstractsObjective To investigate the applicability of the modified memory sub-test of syndrom kurz test (SKT-M) in middle-aged and elderly Chinese.Methods Between March 1,2017,and October 31,2017,at HwaMei Hospital,132 patients receiving elective great saphenous vein high ligation and stripping operation and 96 their accompanying dependents,55-75 years old,were randomly divided into the SKT-M group (n=121) and auditory verbal learning test-huashan version (AVLT-H) group (n=107) using random numeral method.The two groups underwent two corresponding neuropsychological tests respectively on the day before surgery and the second day after surgery.Results There was no significant difference in the baseline characteristics and all the neuropsychological indices at the two time points between patients and dependents (P＞0.05).As a consequence,the data of the patients and dependents were integrated to compare the applicability of SKT-M and AVLT-H.The "low-score" ratio of SKT-M immediate recall (2.4％) was lower than that of AVLT-H test (12.1％) (x2=8.138,P＜O.O1).Besides,the "low-score" ratio of SKT-M delayed recall (5.7％) was also lower than that of AVLT-H test (20.5％) (x2=11.167,P＜0.01).The influence factors of SKT-M were less than that of AVLT-H test.However,the learning effect of SKT-M immediate recall was more significant,for its first testing sore (23.1 ±5.4) was significantly higher than the second one (21.9± 5.1) (t=-3.971,P＜0.001).Conclusion The SKT-M has better applicability to 55-75 years old Chinese than AVLT-H test,but its learning effect should be noted.
