朝文版社区痴呆筛查工具的信度和效度评价

目的 朝文版检测社区痴呆筛查工具(CSID-K)的信度与效度.方法 以韩国社区65岁以上老年人为对象,选择痴呆组(实验组)以及抑郁症组、有文化的健康组、无文化的健康组(对照组)各30名,了解CSID-K评分情况以及他们的社会人口学特征、抑郁症的严重程度、认知功能.结果 CSID-K的认知分(COGSCORE)和扶养者分(RELSCORE)的半分信度、内部一致性信度、评定者之间一致性信度、重测信度分别为0.82,0.87,0.75,0.72和0.85,0.88,0.83,0.79,均优秀(P<0.01).实验组的COGSCORE、RELSCORE、识别功能分(DFSCORE)与简易精神状况检查之间的相关系数分别为0.90,-0.48,-0.76,与老年精神状态进度表B3器质性部分分数之间的相关系数分别为-0.76,0.34,0.60.实验组的COGSCORE、RELSCORE、DFSCORE分别为(21.3±3.1)分、(6.4±4.9)分、(0.3±0.2)分,与抑郁症组的(28.1±2.2)分、(4.0±1.9)分、(0.1±0.063)分和有文化组的(29.2±1.6)分、(2.5±2.1)分、(0.041±0.069)分以及无文化组的(27.7±1.8)分、(3.2±2.8)分、(0.086±0.096)分相比,均差异有显著性(P<0.05).结论 CSID-K能够可靠和有效地筛查出韩社区老年人中的痴呆,同时可用于l临床实际,也可用于跨文化研究.

Reliability and validity of community screening interview for dementia-revised korean

Objective To test the reliable and valid of community screening interview for dementia-revised korean(CSID-K). Methods Study sample consisted of a dementia patient group and three control groups (depression, education, no-education), each of them was composed of 30 community residing elders in Korea. CSID-K was administered, and demographic characteristic, depression, and cognitive function were investigated. Results Split half reability (Guttmans'), internal consistency (Cronbach' s α), and inter-rater and test-retest (two weeks) reliabilities of the CSID-K were excellent. Scores on the CSID-K were significantly correlated with other measures for cognitive function. In addtion, scores on the CSID-K were significantly between the dementia patient group and three control groups. Conclusion CSID-K was a reliable and vaild instrument to screen dementia in Korean community residing old people. It could be used in clinical settings and for cross-cultural researches.
