血管性认知功能障碍的评估：中华成人智力量表的临床应用与建议

Assessment of vascular cognitive impairment： Utility of intelligence scale for Chinese adults and its recommendation

目的 考查中华成人智力量表（ISCA）在血管性认知功能障碍评估中的应用价值.方法 使用ISCA测验64例脑梗死患者,并将成绩与64名健康配对者进行比较.结果 脑梗死组的数字符号、积木构图等6项分测验量表分低于配对者,3项智商低于配对者,差异有统计学意义（P＜0.01）.常识测验、图形推理等6项分测验量表分低于配对组,差异无统计学意义（P＞0.05）.脑梗死组可疑损伤（低于一个标准差）的人数多于配对者,其中,与相似概括、数字符号、积木构图3项测验量表分和操作智商对应的可疑损伤人数（脑梗死组/配对组）分别为16/5、26/7、21/5和24/11,差异有统计学意义（P＜0.01）.ISCA核心分测验和三个量表在脑梗死中应用的Cronbach＇s α系数均＞0.80.结论 ISCA能为血管性认知障碍的评估提供有用的、可信的资料.

Objective To investigate utility of the Intelligence Scale for Chinese Adults in assessment （ISCA） of vascular cognitive impairment. Methods The ISCA was administered to 64 patients with cerebral infarction and their performance on the scale was compared with those of 64 healthy, matched a- dults. Results Scaled scores for six subtests including the Digit Symbol, Block Design of the patients were 1.11-2.30 lower than those of the paired adults, three kinds of intelligence quotients of the patients were 6.70-11.45 lower also, while scores for the other six subtests including the Information, Figural Matrix showed no significant differences between the two groups. Based on the scores, more patients were classified into those with suspected cognitive impairment. However, only four kinds of classification which were based on scaled scores of the Similarity, Digit Symbol, Block Design or the performance intelligence quotient presented significant difference. The numbers of participants classified as suspected impaired of the two groups （patients/matched） were 16/5,26/7,21/5 and 24/11 respectively. The Cronbaeh＇s coefficient for each core subtest, subscale and the full scale was above 0.80. Conclusions ISCA can provide both valid and reliable information for assessment of vascular cognitive impairment.
